Where is the 5,9W Quadcore Temash?
The DC version with 3,9W is boring. No turbo, only 225MHz GPU clock (result in only 57,6 GFLOPs). I think it's clear that Jaguar is not a CPU architecture for low power devices like tablets.

It was obviously a fake by AMD. 8W TDP in nominal mode and 15W in turbo dock mode exactly what we realistically expected. AMD Fans were dreaming.
It's the A6-1450. 5,9 watt without, and 8 watt with turbo.Wait...

Not from AMD :

Quadcore with 1GHz is 8W. Or turbo up to 1,4GHz with 1Core.

Did you all notice how the 25W Kabini took the 17W Ivy Bridge apart in battery life?

No. The turbo will work for all the 4 cores and also the IGP. This solution is useful for the hybrids. If the tablet is not docked, than turbo will be inactivated.
Temash and Kabini not support the traditional turbo core. The CPU cores must be used at the same clock at all time.

No, the turbo only works in combination with less than all four cores:
1,4 - 1T
1,3 - 2T
etc.
Temash with Quadcore and 1GHz has a TDP of 8W.

This chip is not support the traditional turbo core technology, because the for cores are in the same module, and they must use the same clock speed. A different clock can be used in another module, but there is only one module in the Temash/Kabini. This is not a good solution, but that's how it works.
Even the 3.9W DC version is the most powerful x86 SoC in it's TDP range. Similar CPU performance to 1.7 Ghz DC A15 (possibly) and GPU performance is close to PowerVR SGX 554MP4.
Vs. Atom:
Atom Z2760 (2 x 1.8 Ghz, 3W)
Mozilla Kraken (lower = better): 14,500ms
CB R11.5 Single: 0.17
CB R11.5 Multi: 0.52
7-Zip Single: 750
7-Zip Multi: 2,300
3DMark Ice Storm: 2,900
GL/DX Benchmark: 2.3 fps
AMD A4-1200 (2 x 1 Ghz, 3.9W) (est.)
Mozilla Kraken (lower = better): 9,800ms (+33%)
CB R11.5 Single: 0.26 (+50%)
CB R11.5 Multi: 0.52 ( +0%)
7-Zip Single: 880 (+20%)
7-Zip Multi: 1,500 (-35%)
3DMark Ice Storm: 10,450 (+260%)
GL/DX Benchmark: 16.6 fps (+700%)
That assumes perfect scaling, which might not necessarily be the case.
It'll be very interesting to see what Silvermont brings to the table.

Kraken:
Tegra 4 5W TDP (number from nVidia): 6770
Kabini 15W TDP with Chrome: 6512 - http://www.anandtech.com/show/6974/amd-kabini-review/3
We don't need x86 anymore to get more performance in less than 5W. Temash with 3,6W is to slow to be relevant.
Does NVIDIA's number use Chrome? It's useless for comparison purposes otherwise.
AMD is targeting Windows tablets with Temash, where ARM chips (like the Tegra 4) are irrelevant by default.
My bad, thanks. That's not too bad though - at least there is the faster 25W version to look forward to (even though battery life will be worse).

Is it me or something doesn't add up ??
A4-1250 is a Dual core at 1GHz with iGPU at 300MHz and it comes at 9W TDP when a Quad core A6-1450 comes at 8W TDP ?? What the hell ??
Edit: Also, from Dual core 1GHz + iGPU at 225MHz (A4-1200) to Dual core 1GHz + iGPU at 300MHz (A4-1250) and we triple the TDP to 9W ??? no wayyyyyyyyyyyy
Also, 40nm C-70 dual core 1GHz + iGPU(80 cores) is also at 9W TDP, granted they also need a NorthBridge but that also doesn't add up. They kept the same core count and frequency, doubled the Radeon Cores and with a full node shrink they still need 9W TDP ???
I dont know but it doesnt seem ok with me.

nVidia is targeting Windows, too: Windows RT.
And Chrome is much faster in Kraken than IE10. So i think it's fair.
BTW: 1,4GHz Jaguar gets 480ms in Sunspider with IE10. Tegra 4 500ms with Android. And IE10 is much better than anything on Android.

At 25W TDP the dual core + 192 Radeon Cores iGPU Trinity will be way faster than Kabini. Only the price must be lower.
Who said this bullshit? The Temash use a hardlimit on TDP. It won't work above 8 watt. Kabini will, but this is Temash.
Fine,
Temash: Windows 8/x86
Tegra 4: Windows RT/ARM
Tegra 4 isn't competing with Temash, since no one chooses an OS because of a processor. It's the other way round - they choose an OS to build a tablet for, then use the best processor for that task.
Everyone. In nominal mode (without turbo dock) A6-1450 has a 8W TDP with 1Ghz base clock and 1,4 Ghz turbo clock. Turbo dock is 15W and 1,4 Ghz probably on all 4 cores.
if you think ARM A15 is as fast as Jaguar you are thoroughly mistaken. the A6-1450's single core clock is 1.4 Ghz. for every extra thread clocks drop 100 - 200 mhz. dual thread seems to be 1.3 ghz. quad core seems to be 1 - 1.1 ghz.
as for performance
http://www.anandtech.com/show/6974/amd-kabini-review/3
"Here we see a 14% improvement over Bobcat, likely closer to 20% if we normalized clock speed between the partstracking perfectly with AMD's promised IPC gains for Jaguar.
Jaguar seems to be around 9-20% faster than Bobcat depending on the benchmark. Multithreaded workloads are obviously much better as there are simply more cores to run on. In practice, using the Kabini test system vs. an old Brazos machine delivers a noticeable difference in user experience. Clover Trail feels anemic by comparison and even Brazos feels quite dated. Seeing as how Bobcat was already quicker than ARM's Cortex A15, its no surprise that Jaguar is as well "
you can see from the relation between A4-5000 and E-350 that Kraken does not exploit 4 cores. so its a good measure of single/dual thread performance. the Samsung ARM A15 at 1.7 Ghz gets decimated by Jaguar 1.5 Ghz. remember Temash will turbo to 1.4 Ghz for single thread and should not be far behind A4-5000. Even for dual thread it should be just 200 Mhz slower than A4-5000.
Tegra 4 will draw less power but will not stand a chance against Temash in raw performance.
The world is changing. Temash competes in a market segment which does not need Windows and x86.
Consumers want to browse the web, play (vintage 1999) games without hassle, watching videos, doing skype, listen to music, reading books, learning new language etc.
All this is possible on iOS, RT and Android, too. Consumers want the best product. They don't care anymore about the x86 world.
