GeForce 7900 GTX: A Preview
"GeForce 7900 GTX: A Preview"
First off, Nvidia definitely plans to take back the title of world's fastest video card that ATI took away with the Radeon X1900, which tops out at 650MHz core clock speed. To do this they will be switching to a 90nm manufacturing process, compared to the GeForce 7800 GTX which was .11 micron, this inevitably ran into problems with the GeForce 7800 GTX 512, producing them in large volumes. The 90nm process should help greatly and they will need it as everything so far points to a 700-750MHz core clock speed for the GeForce 7900 GTX. You'll recall from our Asus Radeon X1800XT TOP review that ATI hit that clock speed with that card, but it wasn't produced in mass quantities. Hopefully, Nvidia will be able to produce this level at the supply needed.
Memory is also important and DigiTimes claims there will be 256MB and 512MB versions made, this will be the GeForce 7900 GTX and the GeForce 7900 GT with 256MB. Yes, the two cards will be launching at the same time and currently, while everyone has known it will be during CeBit, it looks like March 9th is the best bet, with a hard launch. The memory will feature a clockspeed of 800-900MHz of GDDR3 memory.
