NVIDIA and Intel Are Bickering Again
For a long time, NVIDIA has championed the use of their GPUs in HPC applications, stating that with the right optimizations, their GPUs could be 100 times as quick as traditional CPUs. However, Intel has recently presented a paper titled "Debunking the 100x GPU vs CPU Myth" at the International Symposium on Computer Architecture, claiming that GPUs are only 14 times quick, not a hundred. Naturally, NVIDIA was not too pleased.
TGDaily - Intel has reportedly acknowledged that application kernels run up to 14 times faster on an Nvidia GeForce GTX 280 compared to a Core i7 960 CPU.
According to Nvidia spokesperson Andy Keane, the kernels were likely tested by Intel on the previous-gen GTX 280 GPU without any optimizations.
Is Nvidia's GeForce 14X faster than Intel's Core i7?"[But] it's actually unclear...what codes were run and how they were compared between the GPU and CPU...[Still], it wouldn't be the first time the industry has seen Intel using these types of claims with benchmarks."
