Gateway has outed its updated ID and NV notebook ranges, offering Sandy Bridge processors, USB 3.0 and – on select models – NVIDIA Optimus graphics switching. The Gateway ID47 series is particularly slick, using new LCD display technology to fit a 14-inch edge-to-edge panel into a notebook you’d more commonly find with a 13.3-inch screen.

The Gateway ID47H02u has a Core i5-2410M 2.3GHz processor, 4GB of DDR3 memory, a 500GB 5,400rpm hard-drive, DVD burner and Intel HD Graphics 3000 GPU, and is priced at $699.99. If you don’t mind taking a trip to Canada, however, and spending CA$799, you can get the ID47H03h, which has the same CPU but throws in 6GB of DDR3 memory, a 750GB hard-drive and NVIDIA GeForce TG 540M graphics with 1GB of video RAM and Optimus auto-switching. Canadians will also get the CA$899 ID57H03h, with a 15.6-inch display and 8GB of DDR3 memory, along with the same GPU and HDD as the ID47H03h.

In the US, the 15.6-inch segment is catered for by the NV55S05u, a $629.99 notebook with an AMD A8-3500M quadcore 1.5GHz APU (that can overclock to 2.4GHz), AMD Radeon HD 6620G graphics, 6GB of DDR3 RAM, a 640GB hard-drive and DVD burner. All of the models have an HDMI port, a USB 3.0 port, two USB 2.0 ports, a 1.3-megapixel webcam, WiFi b/g/n, stereo speakers and a copy of Windows 7.

Battery life on the 14-inchers is up to 8hrs, while the ID57H03h can also run at up to 8hrs. The AMD-based NV55S05u can go for up to 4hrs, and has a smaller battery as standard. All of the new ID and NV models are on sale now.

OMAP4470 is architecturally very similar to OMAP4460 with a number of notable changes. First off is that 20% increase in CPU clocks from 1.5 GHz in OMAP4460 to 1.8 GHz in OMAP4470. TI’s comparison point for most of the OMAP4470 specs is the OMAP4430 which has its two Cortex-A9s clocked at 1.0 GHz. The two Cortex-M3 cores remain clocked at 266 MHz for handling multimedia processing and background realtime events. The end result is an effort to both let the two Cortex-A9s remain idle for more of the time, and unburden them during heavy processing. TI feels this dichotomy of two big and fast Cortex-A9 cores for web browsing and very computationally intensive tasks augmented with two ligher weight, low power Cortex-M3 cores offers it unique power savings potential. The two Cortex-M3 cores can offload Thumb and Thumb-2 instructions, as well as some hardware multiply and divide operations from the A9s.

The real interesting change with OMAP4470, however, is a similar two-pronged approach on the GPU side of things. First, OMAP4470 moves from the PowerVR SGX540 present in OMAP4430 and OMAP4460 to a more powerful single core (MP1, if you will) PowerVR SGX544 GPU which offers 2.5x the performance of OMAP4430′s SGX540.

If you recall from Anand’s excellent iPad 2 GPU exploration, SGX543/544 features four USSE2 pipes each with a 4-wide vector ALU churning thorugh 4 MADs per clock. I’m reproducing his table below, but if you mentally replace SGX543 with SGX544 you get the same picture. As an aside, the difference between SGX543 and SGX544 is purely that full DirectX 9 compliance is offered in the latter, making it a possible shoe-in for future Windows 8 platforms.

If you recall the clocks for the OMAP4430, and OMAP4460, you can start to see where TI’s 2.5x claim over its own OMAP4430 comes into play. Going from 304 MHz to 384 MHz is an ~25% increase in clock speed, which adds into the 200% increase in MADs per clock from the change from USSE to USSE2 going from SGX540 to SGX544. Do the math and it works out to almost exactly 2.5x.

The next part of what’s new in OMAP4470 is inclusion of a new hardware composition system for doing display composition without taxing the SGX544. TI wouldn’t disclose whose IP this is, but did acknowledge that it’s from a third party and includes a dedicated 2D graphics core for compositing the entire display. Ordinarily this is done on the GPU, but TI hopes to accomplish the same composition on this hardware accelerator in a more power and bandwidth efficient manner for driving large displays while maintaining low power profile.

When big 3D applications kick in, then SGX544 powers up and takes over, but for the majority of UI paradigms, TI believes its hardware composition engine can enable power savings – analogous to the way the two Cortex-M3 cores augment the two Cortex-A9s. It’s an interesting approach, and TI claims the hardware composition abstraction layer (HAL) is already completed to enable Android and other mobile OSes to leverage that acceleration immediately.

The real hope with OMAP4470 is the ability to drive very high resolution displays as well, up QXGA (2048×1536) and maintaining HDMI 1.4a stereoscopic 3D support. TI expects OMAP4470 devices to arrive in the first half of 2012 with sampling happening in the second half of 2011.

Traditional Netbooks are minimalist, typically sub-$350 laptops that average about 3 pounds and feature Intel’s power-frugal Atom processors. But the specially designated category of Netbooks is fading as more companies and consumers gravitate to plain old small laptops, minus the Netbook nomenclature and minus Intel’s Atom. And, as many analysts are saying of late, the surge of consumer interest in tablets, like Apple’s iPad, is also causing problems for the Netbook.

AMD told me this week it “sold out” of the Fusion processor in its most recent fiscal quarter. “Demand far exceeded supply,” Raymond Dumbeck, product marketing manager for AMD’s mobile products, said in a phone interview.

In further conversations with AMD this week, I was told it has delivered about 5 million Fusion chips since their introduction in the fourth quarter of 2010, and that the total includes somewhere between 3.5 million and 4 million in the most recent (first) quarter. And this number will undoubtedly increase when AMD discloses more numbers at the end of the current quarter. This is enough to dent Atom shipments, since the first-quarter Fusion number cited above comprises more than half the average number of Atom processors shipped per quarter.

“There is a significant interest in Fusion, especially the Llano parts that have yet to be released,” said Jim McGregor, an analyst at In-Stat. Which means more un-Netbooks like Sony’s 11.6-inch Y series–very deliberately not labeled as a Netbook. And Sony has made it clear it’s not interested in the category anymore.

So, is Fusion that much better than Atom? Let’s put it this way: Though AMD’s Fusion processors don’t clobber comparable Atom chips in benchmarks, Fusion offers enough of a performance cushion over Atom for PC makers like Sony, Hewlett-Packard, and Lenovo to create new designs. Sony and HP, among others, are using Fusion in 11.6-inch designs that are designated simply as small laptops. (See CNET review of HP Pavilion dm1Z with commentary about AMD’s Fusion chip performance vis-a-vis Atom.)

Not surprisingly, Intel disagrees about the demise of Netbooks–though in a phone interview Friday, the chipmaker’s marketing chief said tablets are having some impact. “It is fair to say that if people have discretionary income and they’re going to spend 500 or 600 dollars, it’s a tablet today [which] could have been a Netbook a year ago. So, there’s no question there’s a substitution that could be happening there,” said Tom Kilroy, a senior vice president and general manager at Intel’s Sales and Marketing Group.

And a couple of final thoughts about Netbooks: Apple is also doing its part to diminish the format. Though there’s a gaping price difference between, let’s say, a $300 Atom-based 10-inch Netbook and a $999 11.6-inch MacBook Air, Apple offers consumers a clearly superior choice to a Netbook.

And let’s not forget the Chromebook, a dark horse in all of this. These small (11- and 12-inch) Google Chrome OS-based laptops, due in June, are powered by Intel’s latest dual-core Atom processors. Atom’s performance characteristics are better suited to the Chrome OS than Microsoft’s resource- and performance-intensive Windows 7, which runs (slowly) on all Netbooks today.

Codenamed Desna, the new APUs will be part of AMD’s Fusion Z-series, but at this point technical details are rather sketchy. AMD touts the new series as capable of “powering the ultimate HD tablet” and offering “true APU technology,” which is about as vague as it gets.

However, it is clear that we are looking at proper Fusion parts tweaked for tablets. Bear in mind that AMD’s C-50 APU has already found its way into Acer’s Iconia W500 tablet and it is safe to assume that new Z-series parts will offer slightly superior power efficiency than current C-series APUs. The C-50 variant used in the Iconia reportedly consumes up to 5 watts. However, Z-series specs remains unclear at this point, although it seems likely these APUs will be based on the same Bobcat core as Ontario and Zacate chips.

Of course, Z-series APUs will offer full DirectX 11 compatibility and AMD doesn’t fail to mention that they will be more than capable of smoothly streaming full HD video. In addition, AMD promises acceleration in IE9, HTML5, MS Office 10 and Adobe Flash 10.2. External monitors will also be supported and AMD notes that the Z-series should allow “immersive gaming.”

This promises to be a rather eventful summer for AMD and we will try to find out more about the Z-series over the coming days, so stay tuned.

“We have seen many of our embedded customers deploy fanless systems even with our 15W TDP processors in the past. Today we take the ground-breaking AMD Fusion APU well below 7W TDP and shatter the accepted traditional threshold for across-the-board fanless enablement,” said Buddy Broeker, director, Embedded Solutions, AMD. “System designers can now unleash their creativity without being constrained by heat or size issues.”

A fanless solution is crucial for many small embedded systems where the added cost for an active cooling system can be prohibitive or for environments where silent operation is a key requirement. Additionally, many embedded products are deployed in harsh environmental conditions where the presence of a fan represents a potential failure point for the system. The AMD Embedded G-Series platform provides enterprise-class features and performance with the reliability, cost- and power-efficiencies these systems require.

Systems based on the new low power AMD Embedded G-Series platform include an industrial mobile device from Amtek, a Pico-ITX single board computer from Axiomtek, a Qseven form factor computer-on-module from datakamp, and a fanless digital signage platform from iBASE. Additional customers are expected to bring new products to market in the coming quarters.
