First specifications of GeForce 350 GTX have been leaked (unfortunately it is not known if they are true).
New weapons of NVIDIA are based on the core GT300. Its made in 55nm technology process, system is equipped with innovations such as unified units which are doubled in amount (now 480), plus (2GB) and accelerated (GDDR5) video memory, and also raised clocks: core - 830 MHz, a unified shaders - 2075 MHz and memory - 1680 (3360) MHz. Memory clocks have not changed and still with a width of 512 bits. Contrary to the expectations of the new GeForce still will not be compatible with DirectX 10.1.
Rumors say that new GeForce GTX 350 will be 30% faster than GeForce GTX 280.
sorce
bolded is what i want you to read
underlined i think they ment 'memory bus' not 'memory clocks'
if these specs are true....
i think ati will have some major catching up to do.
with those specs, i would imagine that can either almost keep up or keep up with, or outright spank the gtx 295
216GB/s bandwidth,....thats crazy! best i can get my 280 up to is 165GB/s
