GeForce GTX 460 vs Radeon R9 M280X

Intro

The GeForce GTX 460 comes with clock speeds of 675 MHz on the GPU, and 900 MHz on the 768 MB of GDDR5 memory. It features 336 SPUs as well as 56 TAUs and 24 Rasterization Operator Units.

Compare all of that to the Radeon R9 M280X, which comes with core clock speeds of 900 MHz on the GPU, and 1375 MHz on the 4096 MB of GDDR5 RAM. It features 896 SPUs along with 56 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M280X 75 Watts
GeForce GTX 460 150 Watts
Difference: 75 Watts (100%)

Memory Bandwidth

As far as performance goes, the Radeon R9 M280X should theoretically be a little bit superior to the GeForce GTX 460 overall. (explain)

Radeon R9 M280X 88000 MB/sec
GeForce GTX 460 86400 MB/sec
Difference: 1600 (2%)

Texel Rate

The Radeon R9 M280X should be much (more or less 33%) more effective at AF than the GeForce GTX 460. (explain)

Radeon R9 M280X 50400 Mtexels/sec
GeForce GTX 460 37800 Mtexels/sec
Difference: 12600 (33%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 460 is the winner, not by a very large margin though. (explain)

GeForce GTX 460 16200 Mpixels/sec
Radeon R9 M280X 14400 Mpixels/sec
Difference: 1800 (13%)

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 information (counted in megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the interface 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 are processed per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one 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. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
