AnandTech have posted their review of the ATi Radeon 9700 or R300. The results are just astonishing, under UT 2003 the R300 is able to outperform a Ti4600 by 38-54%. Then Anand continues on saying nVidia's NV30 will be faster than the R300! There's 24 pages worth of review by Anand, if you've got the time to read it all - Which I'm going to make time to do.
When all is said and done, there's a reason why ATI and NVIDIA are the two leaders in this market right now. Both companies have figured out the right way of doing things and are currently hard at work bringing the absolute fastest hardware to the market. These two are driving the industry and with the R300 ATI put to rest any speculation that had ever existed about their worthiness as a competitor.More information at AnandTech
ATI won't go the route of 3dfx, they're going the route of NVIDIA and today they just entered the passing lane.
