AVX in HD 3000

AVX in HD 3000

I am getting some tremendous performance out of the cores(with AVX)and the HD 3000 on the i5-2500k. I can understand why the cores with AVX are producing the performance , but can not explain why the HD 3000 is so quick.

Do the 12 Execution Units on the HD 3000 use an AVX-like structure to achieve their performance? I am comparing the Execution Unit(EU)s to Nvidia's Streaming Multiprocessor design with each EU containing a 256bit register set(or longer)to achieve this large computing throughput.

Where could I find out more about the architecture of these EU?

For more complete information about compiler optimizations, see our Optimization Notice.

You can find documentation about the graphics cores on the Intel Linux Graphics Documentation page. Intel HD Graphics 3000 (code-named "Sandy Bridge") is a little bit further down on the page.
