GeForce GTX 480 vs Radeon R7 M260X

Intro

The GeForce GTX 480 features a clock speed of 700 MHz and a GDDR5 memory frequency of 924 MHz. It also features a 384-bit bus, and makes use of a 40 nm design. It is made up of 480 SPUs, 60 TAUs, and 48 Raster Operation Units.

Compare those specifications to the Radeon R7 M260X, which comes with GPU core speed of 825 MHz, and 2048 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is comprised of 384 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 480 will be 177% faster than the Radeon R7 M260X in general, because of its higher bandwidth. (explain)

GeForce GTX 480 177408 MB/sec
Radeon R7 M260X 64000 MB/sec
Difference: 113408 (177%)

Texel Rate

The GeForce GTX 480 will be quite a bit (approximately 112%) more effective at texture filtering than the Radeon R7 M260X. (explain)

GeForce GTX 480 42000 Mtexels/sec
Radeon R7 M260X 19800 Mtexels/sec
Difference: 22200 (112%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 480 is a better choice, by far. (explain)

GeForce GTX 480 33600 Mpixels/sec
Radeon R7 M260X 6600 Mpixels/sec
Difference: 27000 (409%)

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 (measured in MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
