GeForce GTX 580 3GB vs Radeon R7 M260

Intro

Compare those specifications to the Radeon R7 M260, which uses a 28 nm design. AMD has clocked the core frequency at 715 MHz. The DDR3 memory works at a speed of 1000 MHz on this specific model. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 580 3GB should theoretically be a lot better than the Radeon R7 M260 overall. (explain)

GeForce GTX 580 3GB		192384 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 176384 (1102%)

Texel Rate

The GeForce GTX 580 3GB should be much (more or less 188%) faster with regards to AF than the Radeon R7 M260. (explain)

GeForce GTX 580 3GB		49408 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 32248 (188%)

Pixel Rate

The GeForce GTX 580 3GB should be quite a bit (about 548%) more effective at anti-aliasing than the Radeon R7 M260, and also capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 580 3GB		37056 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 31336 (548%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 can be processed per second. This is calculated by multiplying the total texture units of the card by the core clock 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated 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 filling the screen with pixels (the image). The actual pixel rate also depends 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.
