VS

GeForce GTX 470 vs Radeon HD 4850 X2 1GB

Intro

The GeForce GTX 470 features a GPU core clock speed of 607 MHz, and the 1280 MB of GDDR5 RAM runs at 837 MHz through a 320-bit bus. It also is comprised of 448 Stream Processors, 56 TAUs, and 40 Raster Operation Units.

Compare those specifications to the Radeon HD 4850 X2 1GB, which has GPU core speed of 625 MHz, and 1024 MB of GDDR3 RAM set to run at 993 MHz through a 256-bit bus. It also features 800(160x5) Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Pixel Rate

The GeForce GTX 470 is much (more or less 21%) more effective at FSAA than the Radeon HD 4850 X2 1GB, and also will be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 470 24280 Mpixels/sec
Radeon HD 4850 X2 1GB 20000 Mpixels/sec
Difference: 4280 (21%)

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 information (counted in MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
