Intel and Nvidia are locked in a war of words over processor speed. The battle appears to have been triggered by a paper Intel engineers presented last week at the International Symposium on Computer Architecture in France. That paper, entitled “Debunking the 100x GPU vs CPU Myth: An Evaluation of Throughput Computing on CPU and GPU,” asserts that graphics processing units, or GPUs are, in essence, only 2.5 to 14 times faster than central processing units, or CPUs. Nvidia makes GPUs; Intel’s focus is CPUs.
