We already published the first data about the speed of retail version radeon x2900 XTX - This video card coupled with motherboard on base of chipset i975X and dual core processor core 2 Extreme x6800 (2.93 GHz) collected more than 9700 marks in 3DMark06 benchmark.
Associate supplemented these data by the test results of video card on base of chip r600 paired with four core processor core 2 Extreme QX6700 (2.66 GHz). As is known, this benchmark demonstrates increase in speed with transfer from dual core to the four core processor. It is completely regular, that this time Radeon x2900 XTX demonstrated result on the order of 11 400 points. Under similar conditions geForce 8800 GTX get 11 000 marks (overclocked card), but video card geForce 8800 Ultra will for sure prove to be as minimum not slower than Radeon x2900 XTX.
Associate simultaneously reports that the modification Of r600 with memory type GDDR- 3 will have the frequency of only 1600 MHz DDR - This is completely modest for video card class high-end on the present measures. Associates explain, that this memory frequency will be sufficient for guaranteeing the necessary speed level , since video card will have 512-bit memory system bus . Actually , the total capacity can be increased due to the expansion of memory system bus , but not only due to frequency increase . GeForce 8800 GTX and GeForce 8800 Ultra, are satisfied by the 384- bit memory system bus .
The version Or600 with memory of type GDDR-4 will have the memory frequency more than 2000 MHz DDR.
