A portable media player with a 3.3-inch OLED touch screen and an Nvidia Tegra chipset? Sounds familiar.

Nope, we're not talking about the Zune HD. This is the Samsung M1, a PMP that officially popped up on the company's Korean site this past Friday, and that's existence has been confirmed by the requisite blurry photo.

We've yet to see any pricing on Samsung's latest touch-screen media maestro, or any indication that it will be heading to the U.S. (especially not with that DMB tuner it's sporting). What we do know is that the Tegra-based PMP will include Bluetooth audio capabilities, DivX video playback, an active matrix OLED display, FM radio, photo viewer, text reader, microSD memory expansion, and an integrated voice recorder. The leaked photo also indicates the M1 will include a standalone Flash media player.

Should Microsoft worry? Well, any manufacturer going up against the iPod juggernaut should be a little worried, but I doubt the Zune team is losing much sleep over the M1. The Nvidia Tegra chip boasts some impressive specs (especially around battery life), but it's what you do with the chip that counts. Plus, advantages such as HD radio, Zune Marketplace integration, Xbox video compatibility, and one of the best podcast players you can buy make the Zune HD a tough competitor.

Of course, with pricing still unknown for both products, it's anybody's ballgame.

Just last week, we got a peek at Nvidia's new line of HD-video-playing processors in downtown Manhattan. One, the Ion, is a GPU that pairs with an Atom processor to give Netbooks gaming and HD-video-playing muscle, coming soon in Netbooks from Lenovo and Samsung.

The other, Tegra, is an all-in-one chip: it has an HD video processor, but it also has an ARM processor, making it an all-in-one computer on a chip that will be put on phone company-branded Netbooks toward the end of the year, according to an Nvidia representative.

But that's not all, it seems: rumors around the Web are suggesting that the Tegra might be placed in upcoming smartphones as well. With a Tegra processor, these phones would have pretty impressive HD and gaming capabilities.

Add to this Dell's entrance into the handheld Internet device arena and the beefed-up graphics of the iPhone 3GS, and an interesting showdown is in the works between the new-generation smartphones and fall's upcoming crop of graphically superior Netbooks.

Assuming prices hold steady, the costs might be similar, too. A Netbook can currently run between $299 and $500, while smartphones run between $199 and $299, subsidized (and up to $600 unsubsidized).

There are even some new 'tweeners that try to have the best of both worlds--call them UMPCs, MIDs, or whatever you like. We recently reviewed the (almost) pocket-size Viliv S5, which is neither a Netbook nor a smartphone.

For your money, which would you rather have--a smartphone that could handle HD video and gaming but wouldn't necessarily have a physical keyboard, or a graphically improved Netbook? Or are the two not necessarily mutually exclusive? A recent SRG research study found that women under 40 are using smartphones more than PCs as their mobile computing platform of choice. Is this true for men as well? Assuming your budget and gear bag aren't of limitless size, which would you choose?

It's been a big week for small systems.

On May 29, VIA formally announced (here) its "Nano" family of low-power x86 processors. These chips will be especially valuable in small laptops, UMPCs, and so-called mobile Internet devices (MIDs).

Then on June 2, NVIDIA announced (here) its Tegra 600 family, which is also being marketed for MIDs. But Tegra is a very different animal. It's based on an ARM11 processor core, which can run Windows Mobile or Linux but not Windows XP or Vista.

VIA's Nano processors are based on a new microarchitecture that is a giant step beyond previous VIA products and not far behind that of competing parts from AMD and Intel. Unfortunately, in this business, third place isn't a good place to be. VIA's older processors sold in relatively small quantities for low prices. Fortunately, they were very small and thus economical to make and sell.

The new Nano family offers much higher performance, with clock speeds from 1.0 to 1.8 GHz... but it's difficult to know what these clock speeds mean by comparison with AMD's or Intel's, and VIA isn't telling us, at least not directly. In this white paper on the Nano family, VIA only compares the performance of the new chips to its older C7 series.

But VIA does publish some numbers, so I was able to make some comparisons.

Take, for example, the Nano L2100 at 1.8 GHz vs. AMD's 2005-vintage Turion 64 ML-34 at the same speed, as found in the famous Acer Ferrari 4000 (reviewed here by PC World). The single-core ML-34 was much faster despite the clock-speed parity:

Of course, the ML-34 consumes much more power than VIA's processor; the ML-34 has a 35W TDP (thermal design power) specification, whereas the L2100 has a 25W TDP. The L2100 idles at a mere 500mW, but the ML-34 probably consumes at least ten times as much when idle.

To be fair, I'm not sure these are entirely fair comparisons, since VIA didn't publish the details of their system configuration. Also, VIA's performance position probably looks better on simple productivity applications, but I prefer to look at multimedia performance since that's what we usually find ourselves waiting on. It's been a while since we had to worry about out-typing our word processor...

I'm looking forward to seeing some good performance and power figures for Intel's Atom; I think the VIA chips will turn out to be effectively faster but run a little hotter. When I get more data, I'll post a comparison.

But considering that the Nano is generally 60% to 200% faster than the C7 and much more power-efficient than competing products from AMD and Intel, the new product family will likely improve VIA's market position significantly over the next year.

NVIDIA's Tegra, on the other hand, offers no compatibility with existing PC systems or software, and its performance isn't even in the same class. The Tegra 600 family's ARM11 processor core runs at a maximum speed of 800MHz and, because it's a much simpler design, it offers a fraction of the effective performance of VIA's Nano.

So how can it possibly compete with Nano in mobile Internet devices?

Well, one answer is that Tegra is meant to deliver a much more complete solution with much lower power consumption. Instead of being just a core on a chip, like the Nano family, the Tegra 600 and 650 consist of a CPU core, a GeForce GPU, special-purpose hardware for accelerating digital video decoding and camera functions, and a dual-display controller that supports HDMI, LCDs, CRTs, and NTSC/PAL video. All of that on a chip the size of a dime, as you can see in the photo.

But the real answer is that what NVIDIA means by "mobile Internet devices" is different than what Intel (which coined the phrase), AMD, and VIA mean by it.

What NVIDIA means is basically any device with a size somewhere between that of a smartphone and a laptop, which can be used to access the Internet. But this doesn't strike me as a very useful definition; it boils down to encompassing anything like a smartphone with a larger screen. It's one thing to claim the Tegra 600 family supports a "full Internet experience" as NVIDIA did in advance briefings last month, but with the wide variety of sophisticated Web 2.0 websites out there, it really takes a PC-compatible system to deliver that experience.

Now, there's no doubt that the Tegra 600 and 650 will enable fun and interesting gizmos for people who buy lots of gizmos. (And honestly, I'm exactly that kind of person.) But I believe most people are not going to be interested in them. Anything larger than a cellphone is too big to carry around all the time. Anything with a screen smaller than about 7" to 9" isn't big enough for comfortable web browsing and movie watching. Anything with a screen that large might as well be a full Windows-compatible system.

Now, over time, these segments will inevitably blur together. Moore's Law will let us squeeze more performance into handheld devices. Software technologies like Adobe's Flash and Microsoft's Silverlight will allow more websites to work on simpler systems. Hardware like high-resolution LCDs and OLEDs and tiny projection displays will help solve size problems too.

But for now, I believe the Tegra 600 family is aimed at a market segment that isn't ready to develop, whereas VIA's Nano has a big market ready and waiting for it. The Nano won't sell as well as competing PC processors from AMD and Intel, but it should help raise awareness of VIA among PC buyers and encourage PC makers to keep pushing more functionality into smaller packages.

Nvidia is doubling down on its budding processor business for the next generation of mobile computers.

This week at Computex, Nvidia plans to show off its new Tegra brand for mobile application processors. Earlier this year, the company unveiled its first processor for smartphones, the APX 2500. It's now adding two processors to its Tegra brand, with plans to target the emerging Mobile Internet Device category, according to Mike Rayfield, general manager of the company's mobile business.

Nvidia is best known for its graphics processors, of course, but has been taking steps toward a mobile future since its purchase of PortalPlayer in 2006. The company is a member of the ARM universe, with an ARM11 processor core at the heart of the Tegra processors.

The ARM community, companies like Texas Instruments, Samsung, and Marvell, dominates the market for smartphone processors. But they are formulating plans for challenging Intel in the MID category, which by Nvidia's reckoning is loosely defined as everything from a 4-inch minitablet to a subnotebook like the Eee PC.

Intel has huge plans for this market with its Atom lineup of processors, but Nvidia thinks it can carve out a niche by promoting the power consumption of its Tegra processors, Rayfield said. Nvidia says the Tegra 600 series processors won't consume more than a watt of power running at either 600MHz or 800MHz, while Atom is capable of exceeding that limit.

The difference, according to Rayfield, is that Nvidia's design spreads the work out over several different hardware accelerators, rather than just one main processor like Atom. Texas Instruments made a similar argument earlier this year regarding its ability to move up from smartphones into more powerful computers.

One interesting part of Nvidia's strategy, however, is that the company's products are designed to work exclusively with Microsoft's Windows Mobile software. Unlike the PC world, there are several operating system options for mobile computers, and that number will continue to grow with the release of Google's Android and Palm's Nova over the next year and a half.

Rayfield acknowledges that Windows Mobile users of the past haven't had the best experience with their smartphones, but thinks that the most recent version of the operating system, and the forthcoming Windows Mobile 7, give device makers much more freedom to put catchy user interfaces on top of Windows Mobile. Microsoft's software also gives Nvidia's customers a fast route to the marketplace at an affordable price, he said.

Rayfield expects devices using the Tegra processors to arrive by the fourth-quarter holiday season. Nvidia has created its own reference design for a MID using the chips that it will show off at Computex this week.
