GeForce GTX 550 Ti vs Radeon HD 5970

Intro

The GeForce GTX 550 Ti comes with a GPU clock speed of 900 MHz, and the 1024 MB of GDDR5 RAM is set to run at 1026 MHz through a 192-bit bus. It also is made up of 192 SPUs, 32 TAUs, and 24 ROPs.

Compare those specs to the Radeon HD 5970, 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 features 1600 Stream Processors, 160 TAUs, and 64 Raster Operation Units.

GeForce GTX 550 Ti 98496 MB/sec
Difference: 157504 (160%)

Texel Rate

The Radeon HD 5970 will be much (approximately 706%) more effective at AF than the GeForce GTX 550 Ti. (explain)

Radeon HD 5970 232000 Mtexels/sec
GeForce GTX 550 Ti 28800 Mtexels/sec
Difference: 203200 (706%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 5970 is superior to the GeForce GTX 550 Ti, and very much so. (explain)

Radeon HD 5970 92800 Mpixels/sec
GeForce GTX 550 Ti 21600 Mpixels/sec
Difference: 71200 (330%)

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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses 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, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
