GeForce GTX 570 vs Radeon HD 5850

Intro

The GeForce GTX 570 features a GPU core clock speed of 732 MHz, and the 1280 MB of GDDR5 RAM is set to run at 950 MHz through a 320-bit bus. It also features 480 SPUs, 60 Texture Address Units, and 40 Raster Operation Units.

Compare those specifications to the Radeon HD 5850, which has GPU clock speed of 725 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 256-bit bus. It also is comprised of 1440(288x5) SPUs, 72 Texture Address Units, and 32 Raster Operation Units.

Power Consumption (Max TDP)

Radeon HD 5850 151 Watts
GeForce GTX 570 219 Watts
Difference: 68 Watts (45%)

Memory Bandwidth

The GeForce GTX 570 should in theory be just a bit faster than the Radeon HD 5850 overall. (explain)

GeForce GTX 570 152000 MB/sec
Radeon HD 5850 128000 MB/sec
Difference: 24000 (19%)

Texel Rate

The Radeon HD 5850 should be a bit (approximately 19%) more effective at texture filtering than the GeForce GTX 570. (explain)

Radeon HD 5850 52200 Mtexels/sec
GeForce GTX 570 43920 Mtexels/sec
Difference: 8280 (19%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 570 is superior to the Radeon HD 5850, and very much so. (explain)

GeForce GTX 570 29280 Mpixels/sec
Radeon HD 5850 23200 Mpixels/sec
Difference: 6080 (26%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends 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.
