GeForce 9600 GT 1GB vs Radeon HD 4850 X2 1GB

Intro

The GeForce 9600 GT 1GB features a GPU core speed of 650 MHz, and the 1024 MB of GDDR3 RAM runs at 900 MHz through a 256-bit bus. It also features 64 SPUs, 32 TAUs, and 16 Raster Operation Units.

Compare those specs to the Radeon HD 4850 X2 1GB, which uses a 55 nm design. AMD has clocked the core frequency at 625 MHz. The GDDR3 RAM is set to run at a speed of 993 MHz on this particular model. It features 800(160x5) SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Radeon HD 4850 X2 1GB 50000 Mtexels/sec
GeForce 9600 GT 1GB 20800 Mtexels/sec
Difference: 29200 (140%)

Pixel Rate

The Radeon HD 4850 X2 1GB is much (about 92%) more effective at full screen anti-aliasing than the GeForce 9600 GT 1GB, and should be able to handle higher resolutions better. (explain)

Radeon HD 4850 X2 1GB 20000 Mpixels/sec
GeForce 9600 GT 1GB 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: Bandwidth is the largest amount of information (measured in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
