NVIDIA and GPUs VS Intel Sandy Bridge By William Jiang, MLS

In the past, all the work of computing depended on the CPU. The The more powerful the CPU, the faster programs ran. However, besides the CPU there is now the GPU (Graphical Processing Unit on the video card) revolution that NVIDIA current leads with a technology called CUDA. Desktop computers can run at speeds that rival supercomputers of 5 years ago!


the new generation of NVIDIA Echelon GPU’s run at about 10 teraflops (http://gpuscience.com/news/sc10-nvidia-details-10-teraflops-echelon-processor/)

most supercomputers still running the teraflop range. So, this is an example of technology advancing significantly until what used to be a supercomputer not too long ago that cost millions of dollars is now available on the desktop for a few thousand. the graphic below shows how powerful processors can increase their power of CPUs exponentially by using programs that use the GPU like the Mercury playback engine in Adobe Premiere CS5. Below we see that the rendering time of a video decreases by almost 10x. (http://www.tomshardware.com/reviews/xeon-x5680-5600-series-westmere-ep,2692-7.html)

Of course the giant Intel does not want to NVIDIA to have this much power in the computer market. So what Intel is doing with the Sandy Bridge processor is they are putting a middling powerful GPU right on the chip. NVIDIA GPUs still has more power, but with Intel’s economy of scale and most people going with Intel, the behemoth may make inroads into the GPU market and the crush NVIDIA. This senario may be how Microsoft crushed Netscape. With up to eight cores with an integrated GPU Intel is looking powerful.
