GeForce GTX 460 vs Radeon R9 M280X

Intro

The GeForce GTX 460 features core speeds of 675 MHz on the GPU, and 900 MHz on the 768 MB of GDDR5 RAM. It features 336 SPUs along with 56 Texture Address Units and 24 ROPs.

Compare those specifications to the Radeon R9 M280X, which comes with a core clock frequency of 900 MHz and a GDDR5 memory frequency of 1375 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It features 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

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

Memory Bandwidth

In theory, the Radeon R9 M280X should be a small bit faster than the GeForce GTX 460 in general. (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%) better at texture filtering than the GeForce GTX 460. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 460 is the winner, though only just barely. (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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total 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 processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's 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 is also dependant on many 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.
