Wow, my employer sucks and is blocking Phoronix. Anyone want to summarize this until I can check it from home?

Six dual-core PandaBoard ES boards stuck in a wooden dish-drying rack :) One of these draws a max of 5-6 watts under heavy load, so the whole "rack" should stay around 30 watts during cluster benchmarking etc. It's not completely assembled yet so there are no real numbers. Total cost about $1500.
It looks like one PandaBoard can roughly match the CPU horsepower of four APC boards at a slightly lower price, so that's good to know. The Raspberry Pi might still beat out the PandaBoard in terms of purchase cost-to-Megahertz ratio. We'll see. :-)
For comparison, you can now get http://ark.intel.com/products/65703/Intel-Core-i5-3470T-Proc... http://ark.intel.com/products/65735 http://ark.intel.com/products/65714/Intel-Core-i7-3517U-Proc...
You're giving Intel graphics as a pro for servers using OpenCL? Either way, I don't know about this set-up, but next year a set-up with Cortex A15 and Mali T658 will have shared cache between CPU and GPU, which should be a lot more efficient than anything Intel or even AMD has today regarding GPU compute. From what I understand cache "latency" between CPU and GPU is a pretty big problem in the desktop space, and this…
Intel's had cache (last level cache, LLC in the diagram below) since January, 2011:

I'm probably just missing something, but can you explain how the concept is going to fix cache latency CPU GPU?
I'm assuming this: Cortex A15 and Mali T658 will have shared cache between CPU and GPU is what you're looking for.
But as far as i can see, this 'beast' of 12 cores, its not a high end system it runs around 1.3 GHZ ? Do 12 cores makeup for low speed ? there is also a 8 core buldozer amd at around 75 watt but with double the Ghz speed if i remind corectly (thats equals about 35 wat to ratio of 16 cores)

I thought Intel next architecture, Haswell, was going to have the same feature?
