AMD OpenCL APP SDK Beats Intel's Own SDK On Ivy Bridge
Phoronix: AMD OpenCL APP SDK Beats Intel's Own SDK On Ivy Bridge
Here are some OpenCL benchmarks from the Intel Ivy Bridge CPU. Being compared though is AMD's APP SDK, which does support running OpenCL on x86 CPUs, to Intel's CPU-based OpenCL SDK for Linux. To some surprise, AMD's Accelerated Parallel Processing SDK when using the Ivy Bridge CPU is actually faster than the Intel OpenCL SDK on the same hardware.
The problem is Intel really doesn't like OpenCL.
It highlights the weakest link in their hardware. AMD though can actually benefit from strong OpenCL support. It is actually a great selling point, use our software and even if your code runs on Intel hardware you will get the best performance.
As to bench marking I'd really love to see some graphs of better i86 hardware and the better GPUs side by side. This to determine if there really is an advantage to those expensive GPUs. An APU or two thrown in the mix would be nice.
