I have question regarding the theoretical peak FLOPS of my graphics card.
I have a Radeon HD 7970 GHz Edition which has a peak of 4096 GFLOPS.
Now I would wanted to calculate this number.
When I just multiply the core clock (1000 MHz) with the number of cores (2048) I get 2048 GFLOPS.
What am I missing to get the 4096 FLOPS? Does a MAD operation count as two operations?
Then again according to the AMD Accelerated Parallel Processing OpenCL Programming Guide it can execute 4 MAD, ADD or MUL operations per cycle (Page 5-23)?
Which would mean the number of FLOPS would be even higher.
Can someone explain how to calculate the theoretical peak FLOPS?
