Intel研究部門出版了一份處理器運算性能比較報告, 用的是最新的Intel 四核Core i7 CPU處理器, 對比兩年前NVIDIA的舊顯卡, GTX280 GPU圖形處理器.

Intel researchers have published the results of a performance comparison between their latest quad-core Core i7 processor and a two-year-old Nvidia graphics card, and found that the Intel processor can't match the graphics chip's parallel processing performance.

平均來看, NVIDIA GeForce GTX280 (2008年6月發布的) 效能比起Intel 3.2Ghz i7 CPU, 有x2.5倍快的運算效能 .

在某些測試看來, NVIDIA GeForce GTX280 (2008年6月發布的) 效能比起Intel 3.2Ghz i7 CPU, 有x14倍快的運算效能 .

下載來看看吧. Intel的論文名稱叫做 -- ” 其實GPU圖形處理器沒有比CPU快x100倍啦” (Debunking the 100x GPU vs. CPU myth: An evaluation of throughput computing on CPU and GPU)

On average, the Nvidia GeForce GTX 280 -- released in June 2008 -- was 2.5 times faster than the Intel 3.2GHz Core i7 960 processor, and more than 14 times faster under certain circumstances, the Intel researchers reported in the paper, called "Debunking the 100x GPU vs. CPU myth: An evaluation of throughput computing on CPU and GPU."

In a bid to discredit claims that GPUs outperform Intel's processors by a factor of 100, researchers compared the performance of the quad-core Core i7 processor with the Nvidia GPU running a set of 14 throughput computing kernels. The comparison was designed to test the parallel processing capabilities of the chips.
