Intel fleshes out the MID platform with five low-power CPUs

Intel has high hopes for its new Silverthorne/Diamondville-based Atom processors. Intel formally introduced Atom and Centrino Atom in early March and indicated that the processors/platform would be used in a wide variety of devices.

Intel expects for its new Atom architecture to target $40B in new markets. "It’s not just the 1 billion people that have access to the Internet now. It’s the next 2 billion people. It’s not just about selling more PCs, but bringing new devices and new price points to bring those people onto the Internet," said Intel CEO Paul Otellini in March. "We are not talking about repurposing old silicon, but designing new silicon for each of these different areas."

Intel is now taking its first steps to deliver Atom processors to the masses. The first round of Atom processors are the Silverthorne-based units which feature a 13mm x 14mm package size.

The five new 45nm, high-k Atom processor range in speed from 800MHz to 1.86GHz and all feature 512KB of L2 cache. The Z500 and Z510 clock in at 800MHz and 1.1GHz respectively and feature a FSB operating at 400MHz. The Z520, Z530, and Z540 represent speed grades of 1.33GHz, 1.6GHz, and 1.86GHz respectively using a 533MHz FSB. The 533MHz SKUs will feature Hyper-Threading -- a technology that many are familiar with thanks to the unloved Pentium 4 processors.

The family of Atom processors features a thermal design power (TDP) range of 0.65 to 2.4 W; average power range of 160 to 200 mW; and idle power range of 80 to 100 mW.

Prices for the chips range from $45 for the Z500 to $160 for the Z540 in quantities of 1,000.

The Atom Z5xx processors are aimed at what Intel calls the Mobile Internet Device (MID) market. These devices fit into your pocket and are expected to have excellent battery life. Other targeted platforms for these Atom processors include GPS devices, portable video players, and converged tablets.

Backing up Intel's Atom Z5xx processors is Intel's new System Controller Hub (SCH) which was previously known as Poulsbo. The SCH incorporates HD audio, PCIe, USB, and SDIO support. The SCH will also have extended capabilities for WiFi, WiMAX, EV-DO and HSDPA.

Also included on the SCH is a third-party graphics solution which is quite a departure for Intel. In this case, Intel licensed Imagination Technologies’ POWERVR SGX graphics and POWERVR VXD multi-standard HD video technologies. The graphics core is capable of supporting hardware accelerated 720p and 1080i HD resolutions.

"The introduction of Intel’s Centrino Atom processor technology incorporating our POWERVR graphics and video technologies signifies the beginning of a new class of Mobile Internet Device,” said Tony King-Smith, Imagination Technologies’ VP of Marketing. “Imagination looks forward to its continued collaboration with leading industry players to provide products and technologies that help enable ever more dynamic visual user experiences."

"Today is a historic day for Intel and the high-tech industry as we deliver our first-ever Intel Atom processor and surround it with a great package of technology," said Intel Senior VP Anand Chandrasekher. "Mix in the incredible innovation coming from our fellow device makers and software vendors, and we will change the way consumers will come to know and access the World Wide Web. These forthcoming MIDs, and some incredible longer-term plans our customers are sharing with us, will show how small devices can deliver a big Internet experience."

The next big release for Intel's Atom processors will come in the form of the Diamondville-based processors. These processors will go in devices which Intel calls "netbooks". However, we know them more commonly as devices like the Eee PC 900 and ECS G10IL.

The Diamondville-based N270 will run at 1.6GHz using a 533MHz FSB. This is the chip that will find a home in the previously mentioned nettops. According to Intel's latest roadmaps, the chip will be priced at $44 in quantities of 1,000.

Intel is going full-bore with its new Atom processor lineup and it should be interesting to see how the Silverthorne and Diamondville-based machines fare in the marketplace. Diamondville-based nettops are pretty much a sure bet as far as sales are concerned, but many are still not sold on the whole MID concept which would cater to Silverthorne.

I know that for this kind of chip/chipset performance came after size thermal and power, but what are the performance of an hypothetical device that runs on diamondville?
Somewhere I read that in some case it can be even slower than the lame and downclocked cpu in the eeepc.

It's strange that intel never mention this even in cryptic performance/watt/cost graph.

Silverthorne is a "simple" in-order x86 design without the sophisticated predictors found in current desktop processors, so
expect performance to be way below a similarly clocked Core2.

Intels main selling point is that it can run the vast amount of x86
software out there (the marketing drone who gave a presentation about it at my company emphasized that it runs all the closed source video/audio codecs available for windows. We then explained that this
is somewhat irrelevant since our customers want QNX and Linux...)

The Tech Report's excellent article on Atom has some preliminary performance figures - comparisons with a 400MHz ARM11 and suggests that a 1.6GHz HT enabled Atom performs between 1 and 1.3x as fast as an 800MHz Dothan.

I've seen a graph about web page rendering speed, but was an atom 1,6GHz against a "simple" arm11 at 400MHz.
400MHz? Evene Nokia phone now use faster cpu (omap)!
The Atom dominated the graph, but that can be due to a more performance optimized x86 browser too...

From what is know how can be a rel world comparison with a modern and well clocked cortex-a9?

Looks like I'm missing something, but how can chip that draws in average 160 - 200 mW of power create heat of 0.65 to 2.4W ??

That's the guidance to the designers for their thermals. specifies the max power that can be drawn by the processor and to be cooled off (pessimistic view). Its now used as a reference for power consumption of processors.

hand held games

I just hope this finds it's way into something like a PSP or next version of the gameboy. I beleive the processor in the PSP today is at 333Mhz, and can put out some pretty slick looking games (God of War comes to mind) I can only imagine what a system with a 1.8 Ghz chip could do!

It would be nice to see a dual core Diamondville, with max TDP of 5W, and then put it on a low power mobile mobo and you'd be good to go for a very SFF desktop PC. I'd like one to replace my WHS box assuming it would come with more than two SATA ports.




Super Stacking.
By ViroMan on 4/3/2008 6:02:52 AM , Rating: 2
Since the atom CPU puts out so little heat it would be completely possible to now stack several of them into a CPU cube(say 16) and get great multi threading properties. Sure its lacking in many of the qualities of its parent CPU but, im sure the huge gains of super multi threading would far out weigh the cons. Altho I have no idea what the overhead for trying to keep track of 16 CPU's would be.




Size Comparison
By phorensic on 4/3/2008 12:56:15 PM , Rating: 2
Look how large the SCH is compared to the actual proc. Wouldn't it be more beneficial to finally combine the two into one chip, given also that they will be physically close to each other in a MID?

Well, the Atoms are interesting for Laptop makers who want an even smaller windows box (after all, what else is there that windows runs on. CE doesn't count).

The automotive and deep embedded market doesn't (yet) care about it,
simply because they already have proven solutions (ARM/MIPS/PPC/SH based) and are hesitant to adopt a quirky (and concerning firmware: closed and unpredictable) new arch.

Also, most embedded ARMs have *much* more hardware integrated, with a much lower overall power consumption.

So for even smaller windows laptops, yes, the atom will be a success, no doubt. For the more interesting small/embedded device markets (with higher margins) ARM (more precise: not x86) will continue to rule in the forseeable future.

To note that atom is betting on linux and leaving the windows behind, partly due to price and partly due to the amazing scalability of the linux. There are currently plans for variant of Ubuntu and Asianux.

They seem to price themselves out of the mobilephone and settopbox market and others.

They will be grear for micro laptops etc though.

Perhaps the free cell phone market yes. But not for devices like the iPhone.

Honestly I would love a phone with a chip like this in it, a screen like the iPhones, and using Google's new AndroidOS.

I also think this thing potentially has a future in a gaming handheld. 800MHz would still be more than 2x the speed of the CPU in the PSP. And for that kind of screen size, the GPU on the Poulsbo chipset would be more than enough. Imagine a handheld that used DX9 level graphics. At around a 400x250 resolution, an 800MHz Atom and the Poulsbo GPU would do just fine in terms of power. Microsoft could even modify the original Xbox OS to run on it.

These kinds of processors, and x86 processors generally aren't suited for the embedded market. Most embedded products are designed to have the hardware built for a relatively long period of time. The market life for x86 processors are short. It's consumer market related. Any given processor will be dropped (possibly with a price boost at the end) in a relatively short period of time. Processors targetted toward the embedded market will have commitments for the part being made for a fairly long period of time even when considered "obsolete". The processor in an embedded product is "beside the point" of the product and the maker doesn't want to have to redsign it every few years just to keep making the very same product.

Yes, I've been designing products with embedded processors for about 35 years (first one I used was the intel 8008-1, but I'll say that one hasn't been manufactured in a looooong time). :-) But others have been made for ten years or even longer. Imagine building a product that depends upon having x86 silicon that came out out more than ten to twelve years ago (allow for design time from release to product as well).

P.S. - One can mitigate designs by using modular construction with processor cards that then can be replaced by "compatible" modules later on (possibly third party made cards). Just not very cost efficient.

The first thing i thought when intel launched these things was the potential for future smart phones. i think that while what you say is true, they are very power hungry in that kind of device. i deffinately think theres potential.

As for desktops, conglomorates that are green conscience or just money conscience could benefit a lot from investing in a couple thousand of these for their employees to send funny emails to eachother on when they should be working ^_^

Baby steps.
Processor and chipset now, then further down the road they reduce size, reduce power, increase performance, and integrated chipset and processor on the same package.

This isn't really about the now, it's about the future. Start making a few design wins here and there, get some market penetration and start developing a new market (like the Eee PC), and then develop much better solutions in a year or few.

Here, here! Well said.

This may not be PERFECT for PDAs in terms of consumption or PERFECT for notebooks in terms of ability, but Intel's aim IS perfect. I'll bet that you could run a Vista Basic notebook quite well on this. Office, surfing, solitaire, music, photos, movies - perhaps even HD playback when combined with a HD3000 or GF9000 series GPU...

This will be gobbled up by "netbook" makers, carPC builders, HTPC makers...

I mean 1080p output to a HDTV. We know it can decode it and display it at a lower resolution on the device.

First thing that comes to mind.

CAR-PUTER
DVD/DIVX Playback - Dont need HD for the car.
FM Radio with Tivo like functions
Mapping software
Can even tie it in to a car alarm.
Record your driving? Maybe not I speed a little. ;)
Full car diagnostics through the system.

I've been itching to build a great CarPC, but nothing has really stood out as a good enough starting point. A HD and WiMax-enabled netbook would be a great start.

3-4"? Where have you been? :P

Dual monitors.

This up front, custom-fitted in the center:
http://www.xenarc.com/product/1020tsv.html

Then a larger, flush-mounted, non-touch, flip-down LCD for rear passengers.

No one NEEDS anything in a car, but if you're going to do it, may as well do it right.
