GeForce GTX 460 vs Radeon R9 M280X

Intro

The GeForce GTX 460 has a GPU core speed of 675 MHz, and the 768 MB of GDDR5 RAM is set to run at 900 MHz through a 192-bit bus. It also features 336 Stream Processors, 56 TAUs, and 24 Raster Operation Units.

Compare those specifications to the Radeon R9 M280X, which features a core clock speed of 900 MHz and a GDDR5 memory frequency of 1375 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 896 SPUs, 56 TAUs, and 16 ROPs.

GeForce GTX 460 86400 MB/sec
Difference: 1600 (2%)

Texel Rate

The Radeon R9 M280X should be a lot (about 33%) faster with regards to 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 running with a high screen resolution is important to you, then the GeForce GTX 460 is the winner, but only just. (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 largest amount of information (measured in megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core 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 applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
