"The GTX570 appears to be an amalgamation of several graphics cards in one
on first impressions. Firstly, it features the tweaked GF110 core found in
the GTX580. Like the GTX480, it has one stream multiprocessor disabled for a
total of 480 CUDA cores and 60 texture units. And lastly, it sports the same
memory bus and memory/ROP count of the GTX470, the latter feature being
intrinsically to the memory. To compensate for the cut down core, the clock
speeds have been increased to 732MHz on the core and 3800MHz on the memory.
It is officially destined to be the spiritual successor to the GTX470,
fitting in the same power envelope but from a performance standpoint, it is
equivalent to the GTX480 without the drawbacks."
