GeForce GTX 460 vs Radeon R7 M260X

Intro

The GeForce GTX 460 has a core clock speed of 675 MHz and a GDDR5 memory frequency of 900 MHz. It also uses a 192-bit memory bus, and makes use of a 40 nm design. It is made up of 336 SPUs, 56 Texture Address Units, and 24 Raster Operation Units.

Compare those specifications to the Radeon R7 M260X, which comes with a GPU core clock speed of 825 MHz, and 2048 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also is made up of 384 Stream Processors, 24 Texture Address Units, and 8 ROPs.

GeForce GTX 460 86400 MB/sec
Radeon R7 M260X 64000 MB/sec
Difference: 22400 (35%)

Texel Rate

The GeForce GTX 460 should be much (about 91%) better at anisotropic filtering than the Radeon R7 M260X. (explain)

GeForce GTX 460 37800 Mtexels/sec
Radeon R7 M260X 19800 Mtexels/sec
Difference: 18000 (91%)

Pixel Rate

The GeForce GTX 460 is much (about 145%) faster with regards to AA than the Radeon R7 M260X, and also able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 460 16200 Mpixels/sec
Radeon R7 M260X 6600 Mpixels/sec
Difference: 9600 (145%)

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 information (measured in MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, 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 number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
