[
MV4T editor preface / comment: we found this article really interesting, as it demonstrates the computing power of GPUs (Graphics Processing Units) produced by Nvidia (their CUDA-capable graphics cards). The large number of parallel processing GPU stream-processors (aka "cores") can really make a HUGE difference in reducing processing times on compute-intensive operations that can be run in parallel.
What we found even more interesting is that Intel compared their
current high-end Core i7 3.2 GHz processor to a somewhat
older Nvidia GTX280; Nvidia has much newer, and more powerful, 400-series procesors out now. Keep that in mind as Intel points out that the Nvidia GPUs
only ran tests 14 times faster. heh.]
Article Excerpt:
"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.
[...]
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."
