What is the difference between the cudaDeviceProp fields clockRate and memClockRate.
Is the first one SP clock rate and the later memory controller clock rate?
Also somewhere I read that, there are three different clocks in GPU. How does that compare with this?
There’s a paragraph about this in the Anandtech review of the 680, on the first page: http://www.anandtech.com/show/5699/nvidia-geforce-gtx-680-review
There’s still 3 clocks, but an old one is gone and a new boost clock is there. I don’t know what SP clock rate refers to, so can’t answer that.
Thanks! But I still dont get it…I got that the 680 has the shader clock removed. But I have a GTX480 and it shows 2 clocks around 1GHz.
cudaDeviceProp.clockRate : core clock
cudaDeviceProp.memClockRate : memory controller clock
