The Avoton Atom C2750 which is already out now is also 8 cores, but at 2.4GHz and with the entire SoC at 20W. It's supposed to have comparable performance to a Xeon E5520 quad-core/8-thread 2.26GHz CPU from 3 generations back, or about half the performance of a current quad-core/8-thread Xeon E3 1230v3. And it supports virtualization extensions. I agree that I/O and not the CPU is usually the bottleneck though.

That's pretty impressive, actually. I just built a new server, and was comparing 80W and 95W packages. I didn't realize Intel had sorted out power so effectively that they could compete with ARM architecture. (Though, to be fair, this new ARM from AMD is a beast...ARM's grown up and Intel has shrunk down.) Three generations back is still plenty fast for me. I'm running a Core 2 Duo on my desktop, as mentioned, and I don't see any reason to upgrade. I can't imagine needing vastly more in a web server. I think it'd be interesting to see how these two product lines stack up on all the variables: cost, performance, power under load, etc.

I had no idea this existed!

The AMD might have more IO bandwidth - ships with dual 10GbE, while the C2750 ships with 4x2.5GbE (usually 1Gb unless on backplane), although it has PCIe too, who knows about total bandwidth.

  I've got a C2758 on my desk with dual 10G over PCIe. works just fine.

    Except that cost ~$700 for the processor + mobo + NIC, right? Seattle is supposed to be cheaper.

The Rangely C2758 adds QuickAssist for even more crypto/compression throughput. http://ark.intel.com/products/77988/Intel-Atom-Processor-C2758-4M-Cache-2_40-GHz http://ark.intel.com/products/77988/Intel-Atom-Processor-C27... I have one of these sitting on my desk with an m-sata SSD. It compiles emacs just as fast as a R510 with 2 X5570s @ 2.93GHz. When Intel goes 'tock' on these this Summer and manufactures them in 14nm rather than the current 22nm, the power consumption will drop even further. and then there is Denverton. :-)

  I think you mean 'tick' for a die shrink, which is Denverton, and is supposed to have "more cores and more of everything". 'tock' refers to a new microarchitecture, and the details on the generation that will follow Denverton haven't been announced yet. There's also going to be the Broadwell SoC, which will fit somewhere between Denverton and E3 v4's.
