And there is no good OP system for phones that runs on x86 which would be also kind of issue.
I mean, AMD can pull off ~4W TDP for their specifically binned tablet APU at 45 nm (Z-50 which is found in MSI 110W (http://www.msi.com/product/nb/WindPad-110W.html) it's dualcore at 1 GHz and has pretty reasonably GPU in it as well which can play some older games pretty smooth - like Half Life 2 or other Source engine thins at 1280x800. Keep in mind that this thing has also pretty beefy GPU for that TDP and its 64 bit part while Intel lowest end offers are still 32 bit.

Hondo APU Z-60/4.5W TDP is manufactured at 40nm(TSMC), and his successor Tamesh APU will be manufactured on 28nm probably at Globalfoundries. wink.gif

The big problem is what will Intel charge for Haswell at such a ULV setting as their current Ivy ULVs are still much more expensive (200 minimum per chip IIRC). Sure Haswell may perform better and come close to the same consumption...but if it costs more than double the ARM offerings I can't see it really usurping ARM.

I'm wondering what will happen between AMD and Intel with this market. AMD seems to have power consumption down pat and as far as every day tasks, these apus seem to do very well for that. Less power draw means increased battery life, I'd rather have that than game power for a portable device. Seeing how ARM already does decent enough gaming for on the go, I don't really see either doing much more. Idk, we'll see. It seems that if AMD can keep these low watt processors going, even laptops might be beneficial in the long run.

I'm not sure how well the Exynos Dual's power consumption compares to the Atom's since the Exynos is probably a more "complete" SoC. But it still eats up quite a bit of power compared to predecessors. Also, Haswell is 8W not 10W, and that's at high load (as seen in the video running Unigine).

Haswell will probably be expensive but probably not prohibitively so. Current Ivy bridge ULV i3s can be found in some cheap laptops (like the new VIVObook) while offering a decent amount of power. Plus there's the new Atom coming in late 2013

They are indeed more powerful than the N series, especially considering the TDP is doubled.

I give you the win in here. The D series were indeed usable. Not powerful by any means or in any way, but usable.

Well - I highly doubt that most people get these mobile gadgets or netbooks to be their only computers - and for cheking email or watching youtube these things get the job done. Granted I might be a little bit biased as I'm myself pretty much desktop guy - have used a laptop in some periods of my life as my only computer tho. Nowadays - I recently got a ARM tablet, some china reasonably cheap 7'' with ok screen , dualcore cpu and mali gpu - as far as I can tell my tablet does not feel the need to use the second core almost never and even the first core is sitting at some low clocks when I do use the tablet for something - and if I need more power or something that does not run on ARM I just do remote desktop into my desktop system from that tablet.

So for a mobile device power consumption tends to be more important than the raw power of the CPU as long as the CPU is strong enough to pull off reasonably smooth experience for whatever you are doing with it.

Dual Core 1.8GHz Atom D525 is comparable to dual cortex - A15 in this review

The old N series was only single core. The newer N series like N2600 or N2800 are dual core.

Atom Z2760, at tablet CPU with very low TDP, is dual core 1.8GHz (similar CPU specs to D525)

Clovertrail (Z2760) has same CPU specs as D525, both are dual core 1.8GHz. So, the scores in CPU benchmarks should be equal

Comparable, but not likely equal.
