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

Intro

The GeForce 9600 GT 1GB has a GPU core clock speed of 650 MHz, and the 1024 MB of GDDR3 RAM is set to run at 900 MHz through a 256-bit bus. It also is made up of 64 Stream Processors, 32 TAUs, and 16 ROPs.

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GT 1GB 95 Watts
Radeon HD 4850 X2 1GB 250 Watts
Difference: 155 Watts (163%)

Memory Bandwidth

In theory, the Radeon HD 4850 X2 1GB should be 121% faster than the GeForce 9600 GT 1GB overall, due to its higher bandwidth. (explain)

Radeon HD 4850 X2 1GB 127104 MB/sec
GeForce 9600 GT 1GB 57600 MB/sec
Difference: 69504 (121%)

Texel Rate

The Radeon HD 4850 X2 1GB will be quite a bit (more or less 140%) more effective at AF than the GeForce 9600 GT 1GB. (explain)

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

Pixel Rate

If running with a high resolution is important to you, then the Radeon HD 4850 X2 1GB is the winner, by far. (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 max amount of data (counted in megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
