Introduction
Well it’s finally here, the 9 series of GPUs has hit the shelves and the reviews have already poured in thick and fast. I know we’re a little behind everyone else on this one, but our 9600GT review is a bit different. Vvikoo’s monstrous 9600, comes with a whopping Zalman heatsink and some hefty factory overclocking. Let’s see what it’s made of.
Features
- Dual Link DVI supports digital output up to 2560×1600
- HDCP Compliant
- DirectX 10.0
- OpenGL2.1 support
- NVIDIA PureVideo HD Technology
- NVIDIA SLI Technology ready
- NVIDIA nView Multi-Display Technology

G94 and 9600
There arn’t any real differences between the G94 chip used in the new 9600GT cards and the G92 chip used in the 8800GT and GTS refresh. It still supports a unified shader achitecture, nVidia’s own Quantum physics engine and Purevideo. It’s still the same 65nm die size but it does tend to be clocked slightly higher than most G92 chips when at stock.
There are a couple of things that the 9600 has over the 8600 though: it doubles the stream processors to 64, and also doubles the bus width from 128 to 256bit.
