Mind-Blowing Performance per Watt

In the Anandtech article you linked to:

The single threaded performance numbers are just barely ahead of AMD's Jaguar based Kabini SoC. The big difference however is power. I had Intel measure SoC power at the board level while running a single threaded Cinebench 11.5 run on the Atom Z3770 and saw a range of 800mW - 1.2W.

Multithreaded performance puts Bay Trail and AMD's Kabini at similar performance levels. Once again, looking at SoC power however the Atom Z3770 pulls around 2.5W in this test.

Kabini performance at a fraction of the power - in FP workload!

While Silvermont's single threaded FP performance seemed identical to Jaguar, its single threaded integer performance is much higher in the 7-Zip benchmark. Here the Atom Z3770 is 25% faster than the A4-5000.

In multithreaded integer workloads, the Z3770 gets dangerously close to Ivy Bridge levels of performance.

For what its worth, Bay Trail SoC power during the multithreaded 7-Zip benchmark was between 1.9W - 2.5W.

In integer, it blows away AMD, and much better performance per watt than Ivy Bridge!

Bay Trail GPU Performance

13,850 in Ice Storm is quite good! The difference vs. Clovertrail by the way is 5.7x - incredible sandbagging on Intel's part, something I haven't seen in years!

Not to mention the 3DMark physics test is 11.65x of Clovertrail, and ahead of Kabini - suggesting a very good balance of CPU and GPU.

GLBench is a small letdown, in that it's only on par with the iPad4 (which will soon get 2x'ed with A7X), and on par with Snapdragon 600 - which was last year's target. And either AMD is very good at optimizing for GLBench (or Intel is not so good), because Bay Trail tends to fall behind more vs. AMD here.

But overall, this is a good GPU showing. Not the leadership we had originally hoped for, but it's "in the game" while leading on CPU performance and power efficiency, which is still a damned good effort, and quite a jump up from the previous generation.
