GeForce GTX 260 vs Radeon R7 M260

Intro

Compare all that to the Radeon R7 M260, which features GPU core speed of 715 MHz, and 2048 MB of DDR3 memory running at 1000 MHz through a 64-bit bus. It also features 384 Stream Processors, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GTX 260 should be a lot faster than the Radeon R7 M260 in general. (explain)

GeForce GTX 260		111888 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 95888 (599%)

Texel Rate

The GeForce GTX 260 is quite a bit (more or less 115%) more effective at texture filtering than the Radeon R7 M260. (explain)

GeForce GTX 260		36864 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 19704 (115%)

Pixel Rate

The GeForce GTX 260 should be quite a bit (more or less 182%) better at AA than the Radeon R7 M260, and able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 260		16128 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 10408 (182%)

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 max amount of data (measured in megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If 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 texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
