Radeon HD 4870 X2 vs Radeon HD 5570

Intro

The Radeon HD 4870 X2 has a GPU core clock speed of 750 MHz, and the 1024 MB of GDDR5 RAM is set to run at 900 MHz through a 256-bit bus. It also is comprised of 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

Compare those specifications to the Radeon HD 5570, which comes with GPU core speed of 650 MHz, and 512 MB of DDR3 RAM running at 900 MHz through a 128-bit bus. It also features 400(80x5) SPUs, 20 TAUs, and 8 ROPs.

Radeon HD 5570 13000 Mtexels/sec
Difference: 47000 (362%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon HD 4870 X2 is the winner, by far. (explain)

Radeon HD 4870 X2 24000 Mpixels/sec
Radeon HD 5570 5200 Mpixels/sec
Difference: 18800 (362%)

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 transferred over the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 applied per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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