GeForce GTX 560 Ti vs Radeon HD 6970

Intro

The GeForce GTX 560 Ti makes use of a 40 nm design. nVidia has clocked the core frequency at 822 MHz. The GDDR5 memory works at a frequency of 1002 MHz on this model. It features 384 SPUs as well as 64 TAUs and 32 ROPs.

Compare those specs to the Radeon HD 6970, which uses a 40 nm design. AMD has set the core frequency at 880 MHz. The GDDR5 RAM works at a speed of 1375 MHz on this particular model. It features 1536 SPUs along with 96 TAUs and 32 Rasterization Operator Units.

GeForce GTX 560 Ti 128256 MB/sec
Difference: 47744 (37%)

Texel Rate

The Radeon HD 6970 is much (more or less 61%) more effective at AF than the GeForce GTX 560 Ti. (explain)

Radeon HD 6970 84480 Mtexels/sec
GeForce GTX 560 Ti 52608 Mtexels/sec
Difference: 31872 (61%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon HD 6970 is a better choice, not by a very large margin though. (explain)

Radeon HD 6970 28160 Mpixels/sec
GeForce GTX 560 Ti 26304 Mpixels/sec
Difference: 1856 (7%)

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 largest amount of data (in units of MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. 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 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 maximum fill rate.
