#972- AMD Asustek HD 4870 1GB GDDR5 Benchmark

This is AMD's generation now... in the video card subcatagory, of course. The HD 4870 clearly outperforms the GTX 260 by a huge margin. In some tests, the HD 4870 is within 95% of the GTX 280 performance. The competetor, GTX 260, is equally priced, but weaker.We have received some preliminary performance numbers from CJ for Radeon HD 4870 and 4850 vs the current GeForce 9800 series lineup. Apparently, RV770XT with GDDR5 (160W) will run 1.3X faster than RV770PRO with GDDR3 (110W). Two key factors that contribute to the difference in performance between the 2 cards: a 100MHz core clock difference and a faster GDDR5 at 1.96GHz vs GDDR3 at 1GHz. Interesting, RV770PRO will run 1.25X faster than GeForce 8800 GT/9800 GT while RV770XT will run 1.25X faster than GeForce 9800 GTX.Final early specifications of AMD's upcoming 55nm Radeon HD 4000 series graphics cards have been documented for the first time outlining cards from low-end HD 4450 up to big daddy 4870 X2.AMD has managed to create seven GPU's from the three cores RV770, RV740 (using 256-bit memory bus) and RV710 (slower 128-bit memory bus).At the top of the range is the HD 4870 X2 which is a dual-GPU card like the HD 3870 X2 but with much higher core clock speed (1050MHz vs. 825MHz) and using newer GDDR5 memory, which is said to run at 1800MHz DDR. As usual, there will first be the HD 4870 which has a core clock of 1050MHz also but with its 1GB of GDDR5 memory running at a huge 2200MHz DDR.Going down the list is the slightly cut down HD 4850 which uses 512MB of GDDR5 memory clocked at 1800MHz with its core clock running at 850MHz. Moving onto the RV740 is the mid-range HD 4670 and 4650 using GDDR4 memory and at the bottom based on the RV710 is the HD 4470 and 4450 using a mix of GDDR3 and GDDR2 memory.Pricing ranges from $59 USD to $499 USD bottom to top, which is again very competitive against Nvidia.Fake ventrilo, btw
