GeForce GTX 460 vs Radeon R7 M260

Intro

Compare all of that to the Radeon R7 M260, which has GPU core speed of 715 MHz, and 2048 MB of DDR3 memory set to run at 1000 MHz through a 64-bit bus. It also is comprised of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 460 should be 440% faster than the Radeon R7 M260 in general, because of its greater bandwidth. (explain)

GeForce GTX 460		86400 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 70400 (440%)

Texel Rate

The GeForce GTX 460 should be quite a bit (more or less 120%) more effective at anisotropic filtering than the Radeon R7 M260. (explain)

GeForce GTX 460		37800 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 20640 (120%)

Pixel Rate

The GeForce GTX 460 will be much (more or less 183%) better at anti-aliasing than the Radeon R7 M260, and also capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 460		16200 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 10480 (183%)

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 data (measured in megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it 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 high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
