GeForce GTX 560 Ti 448 vs Radeon HD 5970

Intro

The GeForce GTX 560 Ti 448 has clock speeds of 732 MHz on the GPU, and 900 MHz on the 1280 MB of GDDR5 RAM. It features 448 SPUs along with 56 Texture Address Units and 40 ROPs.

Compare those specifications to the Radeon HD 5970, which makes use of a 40 nm design. AMD has clocked the core frequency at 725 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this particular card. It features 1600 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 560 Ti 448 210 Watts
Radeon HD 5970 294 Watts
Difference: 84 Watts (40%)

Memory Bandwidth

In theory, the Radeon HD 5970 is 78% quicker than the GeForce GTX 560 Ti 448 in general, due to its greater data rate. (explain)

Radeon HD 5970 256000 MB/sec
GeForce GTX 560 Ti 448 144000 MB/sec
Difference: 112000 (78%)

Texel Rate

The Radeon HD 5970 should be quite a bit (about 466%) better at AF than the GeForce GTX 560 Ti 448. (explain)

Radeon HD 5970 232000 Mtexels/sec
GeForce GTX 560 Ti 448 40992 Mtexels/sec
Difference: 191008 (466%)

Pixel Rate

The Radeon HD 5970 will be a lot (about 217%) faster with regards to full screen anti-aliasing than the GeForce GTX 560 Ti 448, and will be able to handle higher screen resolutions while still performing well. (explain)

Radeon HD 5970 92800 Mpixels/sec
GeForce GTX 560 Ti 448 29280 Mpixels/sec
Difference: 63520 (217%)

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 (measured in megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that are applied per second. This is worked out 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 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 write to its local memory in a second - measured in millions of pixels per second. The number 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 filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
