Intel Unveils Moorestown and the Atom Z600, The Fastest Smartphone Platform?

The Memory Controller: 32-bit LPDDR1
The Lincroft SoC (or Atom Z600) measures 13.8 mm x 13.8 mm x 1.0 mm. That’s smartphone SoC sized. In order to hit the small package size and in order to keep power consumption down, the single channel DDR2 memory controller from the netbook Atom is gone. What we have instead is a 32-bit wide LPDDR1 memory bus capable of supporting up to 1GB of memory. At 400MHz that’s about the amount of memory bandwidth we had on PCs 10 years ago.
Intel claims that the majority of workloads on smartphones are compute and not memory bandwidth bound so the reduction in memory bandwidth isn’t going to be an issue. Lincroft's caches are the same as Silverthorne before it (24/32KB L1 + 512KB L2).
Compared to smartphone SoCs today, Intel isn’t really outgunned:
| 2010 Application Processor Comparison | |||||
| Memory Interface | |||||
| Apple A4 | 32-bit LPDDR1/LPDDR2 (?) | ||||
| Intel Atom Z600 | 32-bit LPDDR1 | ||||
| TI OMAP 3430 | 32-bit LPDDR1 | ||||
| TI OMAP 4430 | 2 x 32-bit LPDDR2 | ||||
| NVIDIA Tegra 2 | 32-bit LPDDR2 | ||||
| Qualcomm Snapdragon QSD8250 | 32-bit LPDDR1 | ||||
It’s only next year when products based on TI’s OMAP 4430 chip that we’ll see a real ramp in memory bandwidth. Intel will offer a version of Lincroft for tablets with a 32-bit DDR2-800 interface. It can support a maximum of 2GB of memory.
The Lincroft memory controller has less bandwidth than the netbook version, but it's more efficient as a result. Intel included a lot of optimizations, particularly for graphics to improve bandwidth utilization.

Anand, Intel said 3 out of 5, you said one magic device, I think they have one sorted out ... NOKIA is a company needing revolution and this partnership is Nokia's hope for smart phone market.Also outside US and to some extent Europe Nokia has a very strong foot hold, combined with essentially free software such as MeeGo the road looks good, only IF and a big if, they can deliver on software front.

“…NOKIA is a company needing revolution and this partnership is Nokia's hope for smart phone market.”Only problem: Nokia needs a polished solution fast—its average sales price is imploding and the shareholders are restless. A solution that would require them to throw away all the development work to date would be suicidal.
If it takes 12-24 months to implement a totally new architecture, with new software (seems a bit optimistic), only a smartphone maker whose roadmap is in great shape today can afford to make the switch; that'd be Apple. But they have just bulked up with PA Semi and Intrinsity; it'd be hard to imagine much Intel Inside.
Not to mention that Intel's i-series CPUs seem to have been designed to derail Apple's plans of running with a graphics-centric, well-supported CPU. The extra silicon & design time seems to have kept the i3 out of Apple's 13" notebook, while the 15" and 17" have just-a-bit-rocky auto-switch technology to fire up the NVidia GPUs. It doesn't seem that Intel has exactly been courting Apple's product intentions of late.

Intel First SoC based on Atom is not Moorestown, but CE4100(codename Sodaville) is: http://download.intel.com/design/celect/prodbrf/32...http://intelconsumerelectronics.com/
Where is the love for Intel's CE product. Anand you should look into reviewing some products based off these products too.

Sure, is there a shipping product based on the CE3xxxx or CE4xxxx series?I remember there seemed to be something like the Yuixxx from Conceptronix or some similarly named Dutch company.. Did they ever ship?

I am not sure what products have CE products in it... CE devices typically don't advertise this kind of info.Lots of rumors when searching for ce4100 on engadget

Most of those CE4100 results are Intel announcements announcing platform updates or availabilities.The TiVo Premier result, I am not sure why it is even there.... TiVo Premier teardown revealed it is fully Boradcom based, IIRC.
I am very interested to know whether there are any CE4100 products out in the hands of the customers right now... Any Intel employees / PR guys care to offer this information?

Seeing that GPU part is descendant of Paulsbo... I foresee similar fiasco with opensource drivers as with GMA500. Too bad, it really damages Intel reputation.beginner99 - Wednesday, May 5, 2010 - link
funny gma 600. Even if intel like improves gm drivers 100x fold, they will still suck...So you can pretty much say it depends on that.And there go my dreams for useful drivers for my menlow device...it's a PITA. slowing hardware by deliberatley? making horrible drivers.

Intel's graphics performance as they begin integrating into the CPU improved significantly, to the point of competitive. http://www.anandtech.com/show/2952/2Your view point is strictly from a desktop running pixels number as high as 1900x1200 (too much for even the best IGP from nVidia or ATi/AMD), on a smartpone the graphic intensity is not nearly enough... it does not need to win on the highest FPS, it just needs to get 30 FPS or better for a fluid experience.
The graphics component should be fine, no real reason to suspect otherwise.

Given the abysmal Linux support of the GMA500 I foresee a complete piece of crap again that will result in this being used in NO android phones. For me Android is the future of the cellphone and frankly what happened with Paulsbro foreshadows the complete crap that this platform will be on Android and other Linux based platforms (like WebOS). The concerns of the OP are completely justified and I had exactly the same reaction when I read the GPU is based on PowerVR like the piece of crap GMA500.Intel cannot succeed in the Phone space if Linux is treated with the same disdain they presented with GMA500.
