Intel has big ambitions for its low power Oak Trail Atom-based platform, which it says will trash ARM processors in Android performance.  (Source: Intel)

Sadly for Intel quite the opposite proved true in early benchmarks. ARM badly beat an Oak Trail prototype in app performance and heat.  (Source: Tweakers.net)

ASUSTek's Eee Transformer Pad, powered by NVIDIA's dual-core Tegra 2 ARM CPU proved the most powerful tablet in most benchmarks.  (Source: Android In)
The only benchmark Intel's new platform performed admirably in was Javascript performance

By the time the die shrink hits Nvidia will be hitting back with Tegra 3 & 4. Intel is going to be playing catch up, and Nvidia will always have the upper hand with better graphical capabilities.

The funny part is, tegra2s gpu is relatively slow. Future versions will only embarrass Atom. I'm sorry, but I think Atom is not going to make it, as Intel is NEEDING process shrinks to even catch up. ARM is just designed for low power, x86 isn't. Intel will die trying, but I think it will be another itanium moment. Billions in effort for decades, insufficient adoption.

Nah, these are itty-bitty chips that Intel is probably funding with change found in their sofa cushions.

If someone wants to build an x86 tablet, using an Atom or Tegra2 won't cut it compared to the current AMD Fusion which is (A) faster (B) cheaper (C) less heat (D) less power.

Much as I can understand why so many enjoy entertaining such delusions... While it's quite true that the AMD Fusion offerings are faster than the currently available Atoms, they by no means consume less power/generate less heat. Sorry, but it just isn't true. Laptops based on the C-50 idle anywhere from 5 to 10 watts, with full load consumption typically being around 20 watts. The typical E-350 implementation meanwhile ends up at around 10 watts idle and just shy of 30 watts at load. N550 based laptops are in the 4 to 8 watt idle range and 15 watt load... and who knows exactly what Oak Trail based netbooks will be like for power consumption/performance?

AMD Z-01 APU says Hi.

My AMD C-50 (with Z-01's GPU 276Mhz clockspeed) is nowhere near 20 watts at full load. I use Belkin power meter.

Let's see, do I want to believe you, or what I've found to be the best laptop review site available? Not saying that the C-50 is bad or power hungry, just that it is higher power consumption than atom. (C-50 still bests it slightly in single-threaded performance, and easily in graphics/media.)

C-50 based Acer Iconia Tab W500 - http://www.notebookcheck.net/Review-Acer-Iconia-Ta...

Atom N550 based Acer Aspire One D255 - http://www.notebookcheck.net/Review-Acer-Aspire-On...

Oh, and keep in mind that the 'Z' series Atoms are far lower power consumption than the N550. More than easily keeping pace with the amusing Z-01 (which, by the way, is still crippled with the power-sucking M1 FCH last I heard.)

Atom N550 based Acer Aspire One D255 uses a screen with 1024 x 600 pixels, while Acer Iconia W500 uses 1200 x 800 pixels.

Acer Iconia W500 was benchmarked with docking Keyboard+USB Hub+Pointer.

Your point being? Yes, when not under full load (aka, not everything connected and turned on) the power consumption goes down. Yes, there are other differences between the two machines other than the processor used. Yes, you can find both C-50 based and N550 based products that use more power...

But in terms of actual power consumption, the N550+NM10 combination is less than the C-50+M1.

ACER W500 includes a touch screen while Acer Aspire One D255 does not.

18 watts under a furmark and prime95 is nearly meaningless. That has to be above any typical usage scenario, including the vast majority of gaming scenarios. When you have 80 SPs, there is no way around using a lot of power if you really want to.

The ratings seen on CPUs are not for power draw, but heat dissipation. Do remember that.

AMD Z-01 APU (renamed C-50 with 276Mhz GPU) has a max TDP of 5.9 watts. Normal AMD C-50 has 280Mhz GPU clockspeed.

AMD G-T40E APU has a max TDP of 6.4 watts.

Both AMD Z-01 and AMD G-T40E APUs includes dual core at 1Ghz and Radeon HD 6250M i.e. same as a normal AMD C-50.

Intel Atom Processor N550 has a max TDP of 8.4 watts.

And without a controller hub, the only I/O of either of those chips is memory, display, and one PCI-E x4 connection. As well, I've not read anything stating that the processor can actually operate without a controller hub... In which case you must add the 2.7-4.7W TDP of the Hudson M1 FCH to those figures. (TDP of the FCH is according to this chart - http://images.anandtech.com/reviews/cpu/amd/brazos... )

By comparison, that N550 (or the N570) has a TDP of 8.5W and gets coupled to the 2.1W TDP NM10. Or you could go with the Z670 with its 3W TDP, adding another 0.75 watts to the TDP for its SM35 chipset.

3.75W for the lowest power atom configuration compared to 8.6W for the Z-01.

ACER Tablet W500's FCH doesn't match Anandtech's Brazos Hudson FCH feature set.

For example, my FCH has 1 active SATA port instead of 6 active SATA port.

PS; Doesn't include tablet specfic FCH.

Intel Atom Processor Z670 has 1 CPU core, it's missing X64 ISA and supports DDR2-800.

You forget one critical thing, and that is what the overall system performance is like. Atom based machines feel very slow and feel like cheap crap. While I have not personally tested the new AMD Fusion based machines, what I have read indicates that they have a much better level of performance, and may even be worth using.

If temperatures on the Atom based machine are high, with poor performance, and the Fusion based machines are lower with better performance, which is better for the consumer?
