The 9600GT is based upon NVIDIA’s G94 chip which is based upon TSMC’s 65 nanometer process with 505 million transistors. The 9600GT has 64 Stream Processors, which is a far cry from the 240 SPs on the GTX280 and the 800 SPs on the HD4870 cards, but is twice the SPs found on its predecessor, the 8600GT which had 32 SPs and that is the card that it should be compared against.
The Gigabyte card has 1GB of DDR3 memory. Most 9600GT cards have 512MB of memory but Gigabyte decided on the larger amount of memory. All 9600GT cards have a 256-bit memory interface, the first mainstream card to have such an interface after years of having cards like the 8600GT and HD3650 having a 128-bit memory interface. Higher memory bus interfaces mean higher memory bandwidth in general.
Gigabyte’s card has a clock speed of 720MHz for the core, 1.8GHz for the memory and 1800MHz for the Shader clock. This is much higher than NVIDIA’s reference clock speeds for the 9600GT which are 650MHz for the core, 1650MHz for the Shader and 1800MHz for the memory. A 256-bit memory interface means that the Gigabyte 9600GT will have a memory bandwidth of 57.6GB/second on this card.
The 9600GT is fully DirectX 10.0 compliant with support for Pixel Shader 4.0 and Vertex Shader 4.0 features including Unified Shaders, Geometry Shaders and more are supported by the 9600GT chip. ATI has moved on to DirectX 10.1 support, but NVIDIA says that developers only wanted a few features in the SM4.1 feature-set. Today there are no games that require DirectX 10.1 support which is unfortunate and rather lame.
The GeForce 9600GT uses the PCI Express 2.0 interface. PCI Express was released along with the Intel 925X chipset in 2004 to provide higher bandwidth between the motherboard and the video card than the AGP interface that preceded it. The PCI Express 2.0 bus provides up to 8GB of bandwidth on a x16 lane compared to 4GB on the first generation PCI Express bus.
Gigabyte’s specific features include TurboForce, Ultra Durable 2, and ROHS compliance. Turbo Force has three components combining T3 technology and V-Tuner overclocking. T3 stands for Performance Assurance Tuning, Stability Tuning and Power Optimization Tuning. Ultra Durable 2 is Gigabyte’s initiative on their graphics cards and motherboards to use Low RDS (on) MOSFET, Lower ESR Solid Capacitors, and Ferrite Chokes.
