Updated at 3:45 p.m. PST with correction of Motorola, IBM executives' names.
Even the biggest chip companies churn out their share of flops. But the hype that surrounds these chips is more fascinating than the failures.
It's been almost a year since I posted A brief history of chip hype--and flops (part 1). Consider this Part 2.
Itanium
First, I have to revisit Intel's Itanium. Simply because it's still around and still missing production target dates.
Intel's Itanium has been relegated to obscurity if not practical oblivion
(Credit: Intel)The hype: "This design philosophy will one day replace RISC and CISC. It is a gateway into the 64-bit future." This copy was, at one time, posted on Hewlett-Packard's Web site. And analysts were drinking the Kool-Aid too. "I expect Itanium to replace Xeon, but not until 2003," one analyst said back in 2001. (Xeon is Intel's successful, lucrative line of server processors that doesn't include Itanium.)
The reality: Yes, Itanium is still warm, still breathing in the rarefied very-high-end server market--where it does have a limited role. But its architecture will never live in a desktop or laptop or even 99 percent of the servers as once thought. And it certainly hasn't remade the computer industry. And it is still chronically late. This time it's Tukwila that's tardy. The quad-core version of Itanium is late because Intel had to make "some engineering enhancements to the Tukwila platform," according to an Intel statement earlier this month. I can only guess that one day Intel will finally let this failed research project go cold and die quietly.
PowerPC
IBM's original PowerPC platform never lived up to the hype. Even when Motorola and IBM processors populated Apple computers.
The hype: "The PowerPC G5 changes all the rules. This 64-bit race car is the heart of our new Power Mac G5, now the world's fastest desktop computer," said Apple CEO Steve Jobs back in 2003. Jobs, a master of hype (also referred to as a Svengali-like reality-distortion field), continued with this precious quote. "IBM offers the most advanced processor design...and this is just the beginning of a long and productive relationship." (Emphasis added.)
The reality: Apple dumped IBM, Motorola, and the PowerPC in 2005 and it was revealed later that the Mac operating system had been leading "a secret double life" for about five years. But the PowerPC platform had really failed long before 2005. Look no further than these comments from an IBM marketing manager in this 1997 Electronic News article: "Many business school case histories will be written about this failure," Jesse Parker, marketing manager at IBM Micro, said at that time. "No one of the three companies involved in PowerPC executed on their plans. IBM didn't. Motorola didn't. And Apple didn't," he said.
The original PowerPC project was conceived by John Sculley, president and CEO of Apple, and Jack Kuehler, vice chairman of IBM. Phil Hester, an IBM manager at the time, and David Mothersole, a Motorola executive, where also instrumental in starting the project, known initially as "Somerset." But as the PowerPC came to market, Mr. Sculley was pushed out of Apple (and) Mr. Kuehler retired. Their replacements did not have the same enthusiasm for the PowerPC alliance, dooming the project.
In short, the PowerPC failed to challenge Intel in the PC market in a big way. (Though it has been reincarnated as IBM's Cell processor that powers Sony's PlayStation and the architecture still powers IBM servers.)
And I have my own vignette to relate that illustrates one reason why Apple eventually dropped the PowerPC. When Apple first began to crow about the dual-processor Power Mac (circa 2003), a neighbor of mine at the time bought into the hype and purchased an Apple Power Mac tower with two IBM G4 processors (this preceded the dual-processor G5 tower that followed soon after). This thing was a furnace. It quite literally raised the temperature in the room it was in, had about five fans too many, and was deafening, to boot. That was the first time I fully understood the magnitude of Apple's fabrications about IBM's "superior" PowerPC designs. (IBM's less-than-impressive--at that time--chip manufacturing process that was used for PowerPC processors also contributed to the problem.)
AMD Puma
Lastly, turning to Advanced Micro Devices, I'll try to look beyond the botched Barcelona launch in September of 2007 (as I've already covered this in Part 1) and focus instead on AMD's mobile "Puma" platform. Though I can't leave Barcelona entirely out of the discussion because there are some disturbing parallels. (Note: AMD's upcoming Yukon and Congo platforms offer some hope for mobile redemption.)
The hype: Like Barcelona, AMD had too much to say about Puma too long before it was real. AMD started pumping Puma back in April 2007 when the company did one of its many (infamous) soft launches (a PR strategy that it has thankfully ditched). This prompted some editorializing from me as well as other publications. "It is questionable whether...Puma will meet the hype AMD is currently trying to generate though these early announcements," according to a rare editorial from DigiTimes in 2007.
Things got even more dicey at the financial analyst day in December 2007 when AMD said Puma would be delayed until the second quarter of 2008.
It's not so much that Puma (aka Turion X2 Ultra coupled with ATI graphics) is a failure of epic proportions like Itanium, it's that the CPU component (separate from the ATI GPU component) fell so far short of the long, ballyhooed build-up it got.
And it is beaten consistently by Intel in the mobile marketplace. Here's an October 2008 CNET review of laptops with AMD's Turion X2 Ultra. "Turning to AMD's 2.0GHz Turion X2 Dual-Core RM-70 CPU might be an option if you're looking to keep costs down and have only basic computing needs," the review said. "The Acer Aspire 5735-4624 costs only $499 and uses a 2.0GHz Intel Pentium Dual Core T3200; it completed our multitasking benchmark test in one-third the time the HP G60 did. The HP G60 wasn't the last-place performer in our mainstream midprice holiday retail laptop roundup. That dubious distinction goes to the Toshiba Satellite L355D-S7825, also an AMD-powered system."
And there are more unfavorable comparisons. This review at Hexus.net of a Toshiba Satellite 300D with AMD Turion X2 Ultra ZM-80 said the Turion X2 Ultra CPU was "found wanting when compared to Centrino 2." The one bright spot was the ATI Mobility Radeon HD 3650 graphics card--but this speaks more about solid ATI technology than AMD's shaky Turion processor.
Intel has delayed a high-end server chip, billed as the world's first 2 billion transistor microprocessor, originally expected as long ago as 2007.
Tukwila is a quad-core update to the Itanium processor, which has had a less-than-promising run since the original version was announced back in 2001. The chip's architecture--based on explicit instruction-level parallelism--is a radical departure from the x86 design used in PCs today. It was believed at one time that Itanium would replace x86 chips in many Intel-based computers.
So, what's delaying it this time? Intel has "made some engineering enhancements to the Tukwila platform," according to a statement Thursday from Intel. As one enhancement, Tukwila and its follow-on processors on the Itanium roadmap, Poulson and Kittson, will be socket compatible. Intel is also introducing a technology called "scalable buffered memory" to Tukwila platforms. Scalable buffered memory enables higher memory capacities and uses newer DDR3 (Double Data Rate, third generation) memory.
The number of CPU pins that can be dedicated to a memory interface is limited. Scalable buffered memory acts as a memory expander by connecting to multiple DDR3 RDIMMs (Registered Dual In-line Memory Modules) for each CPU memory interface, thus increasing the total memory capacity compared to natively attached memory configurations, according to an explanation provided by Intel.
"Validation testing of the Tukwila processor with the new memory will move the Tukwila platform launch from early '09 to mid '09," and Intel spokesperson said.
Current and past users of Itanium processors include Hewlett-Packard, SGI, NEC, Fujitsu, Unisys, and Hitachi.
The processors are targeted at high-end enterprise servers and high-performance computing systems.
UPDATE An alliance to promote the use of Intel's Itanium processor said a quad-core version of the chip will come out in early 2009. The alliance also disclosed more than a 30 percent jump in volume growth year to year and an update to its partnership with Microsoft, among other announcements.
Itanium is an Intel 64-bit architecture for high-end servers. It differs from the x86 architecture, widely used in PCs. One principal difference is the way the compiler is used. Because the compiler makes decisions about the parallel execution of instructions, the processor can execute up to six instructions per clock cycle.

The quad-core version of the Itanium, code-named Tukwila, will come out in early 2009 and be one of the first "monolithic" quad-core designs from Intel, said Rob Shiveley, worldwide marketing manager of the Mission Critical Server Platform Group at Intel. A monolithic design puts all four cores on one piece of silicon (called a die). To date, Intel has built its quad-core processors by combining two dual-core processor dies. AMD's "Barcelona" Opteron quad-core design puts all four processors on one die.
This will give system vendors the ability to deliver eight-socket systems with up to 32 cores (4 cores per socket), said Mike Mitsch, General Manager, Enterprise Servers, IT Platform Group, NEC Corporation of America.
Tukwila will also have an integrated memory controller and QuickPath Interconnect technology, Shiveley said. This will increase the data transfer rate within the processor. Intel's "Nehalem" processor--due in the fourth quarter of this year--will also be a monolithic design with an integrated memory controller and QuickPath Interconnect technology.
On-chip cache memory for Tukwila will also be increased from 24MB to 30MB. "It is focused on database performance"--that's what the large 30MB cache is for, Shiveley said. Windows Itanium platforms are used, for example, to consolidate a larger number of SQL database servers.
Using two billion transistors (the bulk of the transistors are allocated to the large cache memory), Tukwila will be based on Intel's 65nm process technology and will initially have a clock speed of up to 2GHz at both 170 watts and 130 watts.
NEC's Mitsch said Itanium also supports extremely robust error detecting and error correcting memory. "We're in the process of qualifying up to two terabytes of logical (memory)," he said.
On another front, the Itanium Solutions Alliance announced that worldwide annual Itanium-based factory system revenue and system volume continued to grow in 2007, with a year-over-year increase of 30.8 and 36.3 percent, respectively. The Asia-Pacific region led the way, with year-over-year growth in factory system revenue and system volume of 61 percent and 45 percent, respectively. In Japan, Itanium-based revenue exceeds all other non x86 server platforms, the alliance said.
The alliance also said it is collaborating with Microsoft to deliver new programs and tools to help businesses migrate from "costly legacy RISC systems and mainframes" to Itanium-based platforms. Currently, a fourth of the more than 13,000 Itanium-based applications are Windows Server-based, the alliance said.
Other recent developments include: an NEC enterprise server with dynamic hardware partitioning functionality for Microsoft Windows Server 2008--the NEC Express5800/1320Xf. Sun Microsystems previewed Itanium-optimized Java SE 6 running on an Itanium-based server in several different SOA (service-oriented architecture) scenarios.
While the marquee processor theme at IDF Shanghai is "milliwatts to petaflops," Intel is also set to offer a vision of universal connectivity.
The main theme for the event, which starts Wednesday, Beijing time, refers to "very, very big to very, very small and low power," according to Pat Gelsinger, senior vice president and co-general manager of Intel's digital enterprise group, speaking in a video.
(See: Intel rolls out five new Atom processors.)
"Milliwatts" refers to chips such as Atom, a tiny low-power, low-cost processor destined for ultramobile devices and low-cost desktops typically running either Linux or Windows XP. The first Atom chips will launch in June.
"Petaflops" refers to high-performance computing--what used to be called supercomputing. ("Peta" is quadrillion, or a thousand trillion; "flop" is floating-point operation.) Intel is targeting petaflop supercomputers that would compete with the fastest supercomputer in the world: IBM's Blue Gene/P machines.
Though more technology and product details will certainly emerge in the next two days in Shanghai, the main chip themes are already out there. Gelsinger spelled them out at briefing earlier this month.
The specs for Intel's Dunnington processor
(Credit: Intel)The chip buzzwords are: Tukwila, a new quad-core chip with 2 billion transistors, a whopping 30MB of cache, and a new interconnect technology called QuickPath; Dunnington, a six-core chip for multiprocessor computers that can support four or more processors (in this case, each with six cores); Nehalem, a follow-on to the current "Penryn" processors, it is a new 45-nanometer chip microarchitecture due in the fourth quarter that scales up to eight cores; and Larrabee, a visual-computing architecture that uses many cores ("many" usually means many more than a typical quad-core computer).
In addition to Atom, the processor spotlight will likely fall on Nehalem and Larrabee. Nehalem is a relatively known quantity; Larrabee, a relatively unknown quantity. So interest should focus on the latter.
Nehalem boasts increased parallelism, better branch prediction (to move instructions more quickly through the instruction pipeline), and an on-chip memory controller for increased memory performance--what Intel calls "memory latency reduction." Something, by the way, Advanced Micro Devices already has in its chips.
Larrabee is a graphics processor scheduled for the 2009-2010 time frame. It will include a new vector instruction set to improve the performance of graphics and video applications. Larrabee will be compatible with Intel's popular x86 instruction set, theoretically making life easier for software developers.
On another front, Intel is evangelizing universal connectivity, always a problematic proposition, simply because it invariably promises more (sometimes much more) than it can deliver. Intel puts it this way: "Imagine a day when a single device small enough to fit in your pocket...knows your tendencies and preferences and can adapt and optimize its interfaces to match what you are doing at any point any time...Imagine a day when this device...can dynamically become a hybrid combination of other computing and multimedia devices in close proximity." You get the picture. Intel calls this "Carry Small, Live Large."
On a slightly more practical level, the Cliffside technology is being demonstrated from the Mobile Products Group; it enables a single Wi-Fi adapter to function like two independent Wi-Fi adapters. The hope is that this technology could sync your MP3 and video files without a USB cable, directly and wirelessly connecting your notebook to your TV to view HD movies. More here.
There is also a demonstration of wireless device discovery and setup. This demonstration shows how to detect and connect to nearby wireless displays, using the familiar FnF7 (Function F7 key combination).
