Kindly forward the specification
Sure mate
* ATI Radeon HD 4850 - 650MHz/850MHz/1140MHz core/shader/memory clock speeds, 20.8 GTexel/s (32 TMU x 0.65 GHz) fill-rate, available in 256MB/512MB of GDDR3 memory or 512MB of GDDR5 memory clocked at 1.73GHz
* ATI Radeon HD 4870 - 850MHz/1050MHz/1940MHz core/shader/memory clock speeds, 27.2 GTexel/s (32 TMU x 0.85 GHz) fill-rate, available in 1GB GDDR5 version only
* ATI Radeon HD 4870 X2 - unknown core/shader clock speeds, available with 2048MB of GDDR5 memory clocked at 1730MHz
As for the GT200, the specs I believe are around:
65nm fab process.
478mm^ die size(as big as the original G80 GPU).
192 unified shaders(roughly 1.5 Terraflops of floating point shading power,with the shaders running at 1625Mhz)
DX10.1 support.
512 bit memory bus(using GDDR 3 at 1180 Mhz for a total of 151 GB/sec of memory bandwith)
32 ROP's(23.1 Gigapixels/sec)
Texture fillrate at 69.2 Gigatexels.
GPU clock is at 650 mhz.
1GB ram.
The GT200 will probably be as fast or faster than the HD4870X2 but will also cost about the same amount.
But neither cards have come out nor have been benched so I can't say for sure. What I do know is that a trusted source has claimed that the GT200 (9900GTX) is capable of running Crysis at Very High settings with 4xAA at 1900x1200 at around 25-35fps which is playable in Crysis due to motion blur effects. I don't think even the 9800GX2 is capable of that.
The same person predicted the performance of the G80 and got it spot on. But I will wait and see for myself.
