The 200MHz core is the same core as on any GeForce2 GTS. It's clocked the same and has the same feature set. Nothing is different. The core contains four pixel pipelines, each capable of rendering one pixel per clock with two textures per pixel. Four pixels per clock at 200MHz gives you a 800Mpixel per second fill rate. And at two textures per pixel, we're talking a 1.6Gtexel per second texel rate. Of course, those are the same performance numbers that a GeForce2 GTS has, however, things get different when you look at the memory.
Backing up the GeForce2 GTS core is 64MB of 200MHz DDR SDRAM. 200MHz DDR SDRAM provides close to the memory bandwidth of what 400MHz SDR SDRAM memory could provide. At that clock speed, riding on a 128-bit memory bus, the 3D Prophet II GTS Pro has a grand total of 6.4GBps of memory bandwidth. That is about 1.1GBps more than a GeForce2 GTS and about 1GBps less than a GeForce2 Ultra. That extra memory bandwidth should help boost performance at 1280x1024 and 1600x1200, where memory bandwidth is being pushed but the GPU core is not the bottleneck.
As we said before, beyond the faster memory, the 3D Prophet II GTS Pro sports the same features as the GeForce2 GTS, including the hardware T&L engine, which can draw 25 million polygons per second.
The 3D Prophet II GTS Pro has the Hercules standard cooling setup, the same cooling as their other GeForce2 GTS cards. This includes a heat sink/fan combo for the GPU as well as heat sinks for each memory device. There are eight devices with four mounted on each side of the board, and each device has its own heat sink. This cooling setup may or may not help with overclocking, but it will definitely keep things cool.
