Cold war over prpcessor speed both Intel and Nvidia are fghting it out over supremacy on processor. It all started with Intel engineers presenting a paper 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.
