I've been to www.3dbrew.org to see if there are articles about GPU clock rate and CPU clock rate. Boy, is the interface hard to navigate... In the end, I can't quickly find where it mentions GPU and CPU comparisons with how fast it can calculate heavy tasks. This is for me to figure out if it's a good idea to do matrix calculations in the vertex shader for the GPU, or do it in the CPU, then pass in the results to the vertex shader. Just a quickie. Thanks.
