GeForce GTX 560 vs Radeon R9 M295X

Intro

The GeForce GTX 560 has clock speeds of 810 MHz on the GPU, and 1001 MHz on the 1024 MB of GDDR5 RAM. It features 336 SPUs along with 56 Texture Address Units and 32 Rasterization Operator Units.

Compare that to the Radeon R9 M295X, which makes use of a 28 nm design. AMD has clocked the core speed at 750 MHz. The GDDR5 memory is set to run at a speed of 1375 MHz on this card. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

GeForce GTX 560 45360 Mtexels/sec
Difference: 50640 (112%)

Pixel Rate

The GeForce GTX 560 is a little bit (more or less 8%) faster with regards to AA than the Radeon R9 M295X, and should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 560 25920 Mpixels/sec
Radeon R9 M295X 24000 Mpixels/sec
Difference: 1920 (8%)

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: Memory bandwidth is the max amount of data (measured in MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
