Based on the G92 core, the 8800 GTS 512 features a 65nm design featuring 128 SPUs clocked at 1625 MHz, 64 TAUs (Texture Address Units), along with 24 ROPs (Rasterization Operator Units). These specifications on paper look more impressive than even the 8800 Ultra, all while offering a higher core clock frequency compared to that same card.

The 8800 GTS 512 core comes clocked at an impressive 650 MHz and the GDDR3 memory works at 1940 MHz allowing for a theoretical memory bandwidth of 62.7GB/s, which is surprisingly low. It is not the amount of onboard memory that lets the 8800 GTS 512 down but rather the 256-bit wide bus that it uses. The GeForce 8800 Ultra features a peak memory bandwidth capacity of 103.7GB/s while the GTX has a throughput of 86.4GB/s as both products utilize a 384-bit wide memory bus. But it is not all bad news as the GeForce 8800 GT also uses a 256-bit bus and it performs rather well, so we still have high hopes for the new 8800 GTS 512
