When the Apple tablet comes out, are you in?

The gadget industry is waiting in suspense, wondering if you're going to buy an Apple tablet. Because if you do, they're going to flip the production line's on switch.

The ultrathin MacBook Air exudes some of the aspects of an expected Apple tablet, according to one analyst.

Apple has a knack for creating new categories of devices. The iPhone arguably created the high-end smartphone segment and the design was parroted by dozens of device makers and carriers. The MacBook Air inspired the ultrathin laptop category.

The expected--and highly anticipated--Apple tablet would do the same. Manufacturing companies in Asia are eager to find a new category of devices to fill up their factories, according to an analyst I spoke with recently who monitors these things.

I will make an exception--which I almost never do--and not identify the analyst. He claims to have seen a prototype of the Apple tablet and would prefer not to be identified. (Yeah, I know, more than a few analysts claim they have seen the furtive device. But I will go out on a limb and say I trust him. He claims the MacBook Air has some of the aesthetic qualities of the tablet.)

The point is that many Asia-based manufacturers would be quite pleased if the Apple tablet was a success and, as a result, ushered in a new device category. Needless to say, companies like Dell, Sony, and Acer would quickly follow suit if consumers started snapping up boatloads of Apple tablets.

But Apple will stay above the fray, according to this analyst, offering a device that's very thin, light--and expensive. In other words, don't expect Apple to bring out a $199 tablet, as you may see from other companies that market a media pad-type device. Apple won't be bashful about charging more than $500.

Competing devices will vary widely. My prediction is that the market outside of an Apple-branded tablet will not be a Windows-Intel enclave. Like cell phones and media players, many tablet devices will likely be offered by carriers and device makers using the ubiquitous ARM processor that runs operating systems like Google's Android or the upcoming Chrome OS.

Why ARM chips? They're cheap, very power efficient (necessary for all-day battery life), and have enough horsepower to make a tablet experience compelling. Texas Instruments, Qualcomm, Samsung, and Nvidia are either offering chips now--or are slated to bring out silicon next year--that can easily scale up from smartphones to larger devices like tablets or media pads.

What's that? Don't think you would buy one? Don't think a tablet fills a market need? Get back to me a year from now when you have a sudden epiphany and find yourself in an Apple Store or Best Buy eying one as an essential adjunct to your inner circle of gadgets.

AMD: MacBook issues giving graphics bad rap

by Brooke Crothers
  • 26 comments

Advanced Micro Devices worries that lingering issues--both real and speculative--with Apple MacBooks are giving laptop graphics a black eye.

In a phone interview Tuesday, Stan Ossias, director of marketing, mobile graphics, at AMD, began by asserting that my March 11 post "overstated" the case about heat and the instability of graphics processors in laptops and that some readers may interpret heat issues too broadly.

"In the case of Apple's product, I don't know what happened with Nvidia's GPU but we'd like to avoid having the negative aspects taint the entire industry," he said. (GPU stands for graphics processing unit.)

Most recently, there have been reports of performance issues with Apple's new 17-inch MacBook Pro, which has the Nvidia GeForce 9600M chip. But it's unclear whether Nvidia's chips are really the problem and it's not known how widespread the issues are.

Ossias started off the discussion by spelling out how AMD mobile graphics processors can adjust performance and power consumption to different conditions. (The technology, it should be noted, is applied in various ways by many graphics chips.)

"When the system is calling upon the GPU to do more work, we either increase the voltage or increase the clock speed or increase the operating attributes of the system in order to maximize the performance, and when those things are not in demand we can scale them back so they're not constantly being run at their maximum. This is the way we go about trying to avoid overheating," he said. Strict implementation of these design parameters is particularly critical in systems where there is the greatest potential for overheating: thin notebooks and high-end gaming notebooks, according to Ossias.

AMD provides tools to PC makers, he said, who make the final design decisions on how the GPU will perform in different power-usage scenarios. But sometimes the laptop maker won't make the best choice.

"Somebody may choose a GPU that doesn't necessarily have the best operating characteristics or doesn't deliver the optimal power consumption in all operating ranges. That's a constant development challenge" for laptop makers, he said, then added: "A very, very large proportion of our customers do a very good job of this."

"I don't think Apple does a bad job of this in general. They are extremely meticulous generally," he said. However, in some cases "a product decision is made (where) maybe there is more emphasis put on performance characteristics than on another characteristic. Again, that's another choice that can be made," Ossias said.

Ossias gave an example of the type of graphics chip that would not go into the new MacBook Pro, which is about an inch thick. At the high end of its mobile graphics chip lineup, the ATI Mobility Radeon 4870 can draw as much as 45 watts--a big power draw for a mobile chip. Due to these power characteristics, this would not go into a thin form-factor notebook like the new MacBook Pro, he said.

Last week, AMD announced groundbreaking mobile GPUs, the ATI Mobility Radeon HD 4830 and 4860, based on a cutting-edge 40-nanometer process. Both chips compete in the same general performance category as the 4870 but start at a much lower power-consumption level (the low 20-watt range) and "therefore you can actually get the 4830 into a thin and elegant notebook design," according to Ossias. AMD's current 4650 and 4670 can fit into thin form factors also, he said. These latter two chips would be in the same class as the Apple MacBook Pro's Nvidia GeForce 9600M, he claimed. The 9600M is the chip alleged to have heat and performance issues.

"I know that when Nvidia announced (in October of last year) publicly that it was recalling or having to rework some of its products and they took a big write-down, we had to address concerns from our customers that we were not also experiencing packaging failures because of the overheating and design flaws that they were experiencing in their product line," he said. "So, we basically had to go and calm down a lot of our customers and say, look, this is not something that's inherent to our technology, it's not something that you have to expect from any GPU."

Apple and the Nvidia 'problem'

by Brooke Crothers
  • 45 comments

Nvidia is again at the center of a graphics tempest in the media, this time surrounding performance issues of Apple's new 17-inch MacBook Pro. Two little pesky questions haven't been answered yet, however. Are Nvidia graphics chips really the problem? And are the issues really that widespread?

Postings in an Apple discussion forum cite a smorgasbord of problems: Some cite the Nvidia GeForce 9600M, while others point to issues with fan speed. Another post points to faulty wiring and another to the main processor (i.e., Intel). But this is just one forum. Does this really indicate widespread problems?

Does the Apple MacBook Pro 17-inch unibody have chip issues?

I haven't heard back from Apple. Nvidia had no comment Monday.

So, I spoke with a few people who have informed insights into potential problems. Not all would speak on the record, however. Jon Peddie of Tiburon, Calif.-based Jon Peddie Research, which tracks the graphics chip market and does testing on graphics chips, said he hasn't tested the new MacBook Pro yet. Generally speaking, however, a GPU problem of this sort would dictate a BIOS change to adjust the fan speed (one of the possible solutions proposed already). Or, if it's more serious, the graphics board would need to be replaced. (BIOS stands for basic input-output system; GPU stands for graphics processing unit; CPU stands for central processing unit.)

"If either of those conditions were true, Apple would be issuing an alert," he said. The alternative is for Apple to deal with the alleged problem on a piecemeal basis, one customer at a time, Peddie said.

The latter scenario--the status now--of course leads to a lot of speculation and attempted diagnoses among users.

I also contacted another analyst, Linley Gwennap, principal analyst at the The Linley Group. He made some obvious points but important in the context that it's not necessarily the GPU. Basically he said that if any chip exceeds the "thermal design budget," the system becomes unstable.

Other people I contacted (who wished to remain anonymous) said the issue appears to be more of a fan issue than a GPU issue. But the jury is still out. And, let's be clear, Nvidia has been faulted for past MacBook glitches. The most recent being in October. Will Nvidia be perpetually plagued by fallout from past problems? The 1994 Pentium FDIV bug was an Intel albatross for years.

I see another ancillary issue--not necessarily directly related to the MacBook Pro issue discussed above--that needs to be addressed. Here's the proposition: you want better graphics but you also want a sleek laptop like the Apple MacBook Pro. Well, if you're pushing the outside of the graphics-performance envelope, something's got to give. It's like saying: I want a car that goes from zero to 60 in under four seconds but with low emissions.

The truth is high-performance discrete GPUs and Intel CPUs--even the ones with the "m" (for "mobile") suffix--will sometimes wreak havoc when they're stressed inside enclosures only 1-inch high (i.e., many laptops). But I'm stating the obvious (I think). Anyone who has maxed out a relatively high-performance GPU or CPU in a laptop knows the real meaning of the euphemism "uncomfortably hot"--a phrase often used in discussion forums.

Overheating results in a lot of unpleasant (and sometimes seemingly unrelated) surprises, including BSOD (Blue Screen Of Death), automatic (arbitrary) shutdown, and, as in the case of the MacBook Pro, graphics artifacts.

Some people will always point their finger at Nvidia (or ATI) but I submit that some of those people experiencing problems would be the first to raise a stink if Nvidia didn't offer a high-performance laptop graphics chip to run Crysis at the frame rates and resolutions they demand. Yes, a product should work as advertised but there are limits to what a GPU (or CPU) can do inside the thermally challenged, cramped quarters of a laptop.

Not that Nvidia is absolved of any and all crimes. Far from it. As I stated above, Nvidia has had its share of problems that were its own fault. But even Intel's integrated graphics (theoretically the most power efficient) has heat gotchas of its own. Heat has been an issue in the first version of the Intel-graphics-based MacBook Air (when playing video)--which I can vouch for since I own a first-generation MBA. And I have another laptop (from a top-five PC maker) with integrated graphics that immediately heats up (and sometimes overheats) when running video.

But back to discrete GPUs. If you want desktop-level graphics in your sleek laptop, then you're going to have to take the heat and, consequently, in some cases--if you push the graphics card--instability and graphics anomalies. That doesn't make it right. It's just a fact of life.

Apple pulls MacBook graphics update

by Tom Krazit
  • 29 comments

A software update meant to fix some issues with graphics on the new MacBooks has been removed by Apple.

(Credit: CNET)

Correction, 11:48 a.m. PST: This story misstated when the Apple notebooks were redesigned. It was October 2008.

Apple has withdrawn a software update that was supposed to help MacBook owners deal with graphics issues, but that apparently failed to solve many of the problems.

AppleInsider spotted the disappearance of the update on Wednesday, after Apple had released it on Monday. The Web page that hosted the update has been removed from Apple's site, but a copy was available in Google's cache; missing the pertinent file, of course.

As AppleInsider notes, it's not clear why Apple pulled the update after just two days. It was designed to fix issues with flickering displays raised by some MacBook owners with the use of external monitors over the miniDVI ports on the new MacBooks. A scan of Apple's discussion boards shows that the update didn't seem to fix the problem for everyone and in some cases, made the problem worse.

This issue only affects those with the MacBooks, MacBook Airs or MacBook Pros redesigned in October, and it seems to only be a problem when running the integrated graphics on those machines; Nvidia's discrete graphics don't appear to cause the same problems. A separate issue involving HD video playback on Macs running the older Nvidia GeForce 7300 GT graphics was also contained in this particular update.

Video, memory issues with MacBooks being reported

by Tom Krazit
  • 62 comments

Early adopters of Apple's latest MacBook Pros and MacBooks (shown here) are reporting glitches with the laptops.

Problems with Apple's newly redesigned MacBooks are being reported on Apple discussion boards and across the Internet.

The new notebooks, which have already run into problems with the trackpad, are said to have problems with video performance, third-party memory chips, and staying in sleep mode. It's always difficult to get a sense of how widespread such problems are from tracking message board posts--and every computer ever made has had problems--but the volume of such complaints regarding the new systems seems to be increasing.

Gizmodo collected some of the more pressing problems in a post Monday. The memory issue involves crashes that appear to be linked to adding third-party memory chips into the new MacBooks and MacBook Pros. Apple charges way more for memory upgrades than other companies such as Crucial or Other World Computing, so savvy Mac users interested in adding memory on their own often choose one of those products.

That post also highlights an issue that involves the MacBook Pro being unable to stay in sleep mode, turning itself on when closed every minute or so, or freezing when woken up by the user. That issue doesn't seem as serious as the memory one, but if you've noticed this problem resetting your MacBook's PRAM seems to have worked for some people.

New MacBook Air's newness lies within

by Brooke Crothers
  • 17 comments

The latest MacBook Air masks a lot of new electronics under an old skin.

To me, the new MacBook Air (MBA) is truly a second-generation product despite its unchanged appearance. But before I explain why, let me clarify where I am coming from.

I have been using an MBA for the last eight months. Why the over-priced Air? I am a minimalist when it comes to computers (though not necessarily when it comes to spending money on computers). The more spartan the laptop is, the better. In a well-executed design this translates to more portability, which, for me, takes priority over performance and ports.

And this is especially true for the Air. The economy of design dictates lower performance and fewer connectors than mainstream laptops.

Updated MacBook Air has new processor, chipset, graphics, and solid state drive

(Credit: Apple)

Having said that, the new Air seems to have made significant gains in performance. (Again, this is a preview, so only benchmarks will bear this out.) The Air uses Intel's newest Penryn-architecture low-power mobile processors, not the older Merom processors--which were, let's be honest, already dated even way back in January when Apple launched the Air.

Penryn-class processors come with 6MB (versus the Merom's 4MB in the previous Air) of cache memory and faster front-side bus speeds (1066MHz versus 667MHz). Of course, other MacBooks use Penryn chips too but it is significant that these powerful mobile processors are now being squeezed into the Air's form factor.

The widely reported use of Nvidia's GeForce 9400M graphics is another big plus. This is a step up from Intel's integrated graphics, which for too long has really been the only choice for subnotebooks and ultraportables. Better game playing and the ability to drive Apple's new 24-inch LED Cinema Display as well as the 30-inch Cinema HD Display are other benefits. (More on the GeForce 9400M here.)

And let's not forget memory. The Air uses DDR3 memory versus the DDR2-specified chips of the previous Air. DDR3 delivers better bandwidth and lower power consumption than DDR2.

Storage. Generally speaking, solid-state drives are faster than hard disk drives, especially when reading data. The Air and the ThinkPad X300 legitimized SSDs. The new Air takes this to the next level with a larger 128GB solid-state drive (versus the previous model's 64GB SSD). The newer 128GB (and larger-capacity) solid-state drives are based on multilevel cell technology. MLC allows larger capacities at lower cost. But MLC-based drives typically don't deliver the performance of single-level cell (SLC) drives. Dell, for example, offers its Latitude E4200 ultraportable with both high-performance SLC drives and lower-performance MLC SSDs.

Last but not least is price. OK, so $2,499 is not a steal (for the 1.86GHz model with a 128GB SSD). But look at it this way, you get a lot more for the same price as the previous Air. You get a faster processor, better graphics, speedier memory, and a larger solid state drive. Though I wouldn't call this a great deal by any means, Apple could have priced it higher. (Apple has been known to push the envelope on pricing.)

Longstanding Issues

Let me also address some longstanding issues I've had with the Air. I currently use one of the original models--launched back in January--that comes with a 1.8GHz processor and 64GB solid state drive. The Air's aluminum body is wonderful, but it hasn't maintained the tolerances that it had at first. Specifically, the seams just below the keyboard sometimes creak (for lack of a better word) and, at times, noticeably expand and contract. Let me be clear: this is not a big issue and is noticeable only occasionally. Most users probably wouldn't notice this.

Heat. I hesitate to cite heat as an issue because every laptop I have ever owned has had heat issues--some much worse than the Air's. It's a little like complaining about your car's engine block getting warm. But because the aluminum body itself acts as a heat sink of sorts, excessive heat can become an issue when the Air is pushed to its limits. That is, a lot of open applications and a heavy workload.

Screen response time. This could be subjective to some extent but the LCD's response times seem to be slower than, for example, the response times I get from my other laptop: the 3.3-pound HP 2510p. In other words, whenever I go back to working on the 2510p after working on the Air for a while, I feel that the screen response times are better on the 2510p.

But overall the Air is an amazing piece of engineering and a delight to use.

More MacBook rumors and pics surface

by Dan Farber
  • 22 comments

Corrected at 2:45 p.m.: This report misidentified one of the MacBook Pro's rumored features; it is a mini-DVI connector. The report also misidentified the Web site attributed to the original report. It was AppleInsider.

Despite the tanking economy, Apple's new MacBooks due to be unveiled Tuesday are creating some buzz (see Techmeme) and propping up Apple's stock price. The latest alleged pictures in the wild are of the new aluminum case (above) of the forthcoming systems posted on MacX.cn.

According to AppleInsider.com, the new higher end MacBook Pro will include a mini-DVI connector and a single FireWire 800 connector.

Overall the changes don't look major other than the shift to aluminum and the rumored substitution of Intel's chip set of Nvidia's graphics chip set, as reported by AppleInsider.

Apple to repair MacBooks with faulty Nvidia GPUs

by Anne Dujmovic
  • 17 comments

An investigation by Apple shows some MacBook Pros may have faulty Nvidia graphics processors after all, despite Nvidia's earlier assurances to the contrary, the computer maker has announced.

Apple said it will repair at no charge MacBook Pros where the Nvidia GPU has failed, or fails within two years from the purchase date. Problem signs include distorted or scrambled video, or no video on the screen though the computer is turned on. Models that might be affected are 15-inch and 17-inch MacBook Pros with Nvidia GeForce 8600M GT graphics processors. The computers were made between May 2007 and September 2008.

This past summer, Nvidia acknowledged that a packaging defect had led to a graphics chip problem that affected some notebook computers, including those made by Dell and Hewlett-Packard. The chipmaker said in July it was taking a one-time charge of $150 million to $200 million to cover expenses relating to the glitch.

In a post about the problem, Apple said that back in July "Nvidia assured Apple that Mac computers with these graphics processors were not affected." But the computer maker's own investigation showed some models might be affected.

Nvidia's director of PR and events, Derek Perez, told MacWorld on Friday the company "has worked diligently with Apple." According to Perez:

"Our analysis shows that a failure in an Apple MacBook Pro notebook is remote. However, Apple, like other OEMs, decides on their own how to handle their warranty and repair programs, based upon their own quality standards. Regardless, we stand by our products, thus the reason why we set aside such a large reserve, and we have and will continue to work closely with Apple and their customers."

Nvidia cuts estimates, citing product delays and failures

by Tom Krazit
  • 1 comment

Nvidia's fortunes took a turn for the worse during the quarter, as slowing sales plus faulty products never add up to anything good.

The company announced Wednesday that revenue and gross margins for its second quarter will come in below its own projections, blaming a delay in the ramp of a new product, price cuts prompted by competitive pressures, and a general economic malaise. Analysts were expecting revenue of around $1.1 billion, but revenue now will be just $875 million to $900 million for its second quarter, which ends on July 27.

And then on top of that, Nvidia will have to take a one-time charge between $150 million and $200 million to account for "a weak die/packaging material set" used with certain graphics processors and platforms in some notebooks that is causing system failures. The company claimed the problem was in the interaction between its products and the rest of the system, but said it would switch to a more sturdy material for its chip packages and work on improving the thermal management software of its products.

Nvidia has been throwing its weight around in recent months, picking a fight with Intel over the most proper way to configure a PC and expanding its efforts to develop processors for mobile devices. It now has some work to do on its core graphics products, which might give rival AMD's ATI division a chance to score some wins.

Industry group to evaluate Apple's OpenCL as standard

by Tom Krazit
  • 9 comments

The PC and mobile-computing industries are getting together to propose a standard for computing on graphics processors, and they are going to start their evaluation with Apple's OpenCL technology.

The Khronos Group, an industry consortium that already administers well-known standards like OpenGL, announced the creation of a Compute Working Group on Monday to develop an industry standard for allowing software developers to tap into the performance offered by graphics processors, or GPUs.

Many familiar names dot the list of founding members, including chip companies such as AMD, Nvidia, and Intel, mobile industry representatives such as ARM, Motorola, Samsung, and TI, and Apple.

GPUs are perhaps best-known for rendering realistic mayhem in the never-ending sequence of PC shooter games, but they are taking on new roles. Newer operating systems like Vista are placing more graphical demands on the PC, and programmers in the scientific community are also interested in using the power of GPUs to process certain types of applications.

GPUs are very good at taking specific tasks, breaking them down into pieces, and solving them at an extremely high rate of speed using multiple processor cores. But they aren't good at handling the random assortment of software that we all have on our PCs or Macs, which in turn hasn't been programmed to take advantage of multiple processor cores, for the most part.

To that end, companies like Nvidia, AMD, and Intel have all been working on ways to make it easier for software developers outside of the scientific computing industry to take advantage of the unique characteristics of the GPU.

In typical fashion, however, they all came up with different implementations. Nvidia has CUDA, AMD has Stream Computing, and Intel has its Larrabee project, which actually hasn't been released.

When Apple unveiled Mac OS X Snow Leopard last week during its Worldwide Developers Conference, the company noted that the operating system would feature a technology called OpenCL to make it easier for software developers to access graphics processors. The Khronos Group will evaluate OpenCL as a proposed standard, but there's no guarantee that all companies will eventually head down that path.

That's because there's a notable company missing from the founding members of this group: Microsoft. If Microsoft chooses to go down a different path with the next implementations of Windows and Windows Mobile, it will be hard for the chip companies to resist following suit.
