GeForce 9600 GSO 512MB vs Radeon HD 4850 X2 1GB

Intro

The GeForce 9600 GSO 512MB makes use of a 65/55 nm design. nVidia has set the core speed at 650 MHz. The GDDR3 memory works at a speed of 900 MHz on this model. It features 96 SPUs as well as 48 Texture Address Units and 16 Rasterization Operator Units.

Compare that to the Radeon HD 4850 X2 1GB, which has a core clock speed of 625 MHz and a GDDR3 memory speed of 993 MHz. It also makes use of a 256-bit memory bus, and uses a 55 nm design. It features 800(160x5) SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Difference: 18800 (60%)

Pixel Rate

The Radeon HD 4850 X2 1GB is quite a bit (approximately 92%) better at FSAA than the GeForce 9600 GSO 512MB, and also capable of handling higher screen resolutions more effectively. (explain)

Radeon HD 4850 X2 1GB 20000 Mpixels/sec
GeForce 9600 GSO 512MB 10400 Mpixels/sec
Difference: 9600 (92%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
