Nvidia 8800 GTS 512MB Review – The Essence of 128 Shader Processors

The G92 runs at some 650MHz on the "core" with 1625MHz shaders. Extra power is necessary for the GPU to run at higher clockspeeds, which explains why the 8800GTS has an additional power phase for the GPU. The 8800GT in comparison has a 600MHz core with 1500MHz shaders. With great processing power comes greater heat, hence the TM68 cooling unit.

The heatsink is a two-slot solution instead of a one-slot unit used in the GT.

Beefy TM68 design with 3 heatpipes.

The blower draws air over the power regulation circuit too.

Delta manufactures the cross-blower for the TM68.

The 0.48A fan is made by Delta Electronics. It’s a 4 pin design with PWM control onboard. Bulky coolers run quieter in fact, since there is sufficient surface area not to necessitate a fast fan. The heatsink base also acts as a heatspreader for the gDDR3 RAMs. Generic thermal paste with meshed thermal pads form the interface for the GPU and the RAM and Voltage Regulation Modules. Standard NVIDIA fare, that is.

Voltage regulation is acheived by a Primarion PX3544, just as it is on the 8800GT.
You could acheive higher voltages on the 8800GTS using the widely circulated 8800GT voltage modification techniques.

With bumped clocks and resurfaced Stream Processors, the GTS looks like the next big thing out there that is aiming for your paycheck while you struggle through Crysis with your last generation graphics accelerator. On to the benchmarks!
