GeForce GTX 460 vs Radeon R7 M260X

Intro

Compare all of that to the Radeon R7 M260X, which features a core clock speed of 825 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 460 should in theory be a lot faster than the Radeon R7 M260X overall. (explain)

GeForce GTX 460		86400 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 22400 (35%)

Texel Rate

The GeForce GTX 460 will be quite a bit (about 91%) better at AF than the Radeon R7 M260X. (explain)

GeForce GTX 460		37800 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 18000 (91%)

Pixel Rate

The GeForce GTX 460 will be quite a bit (more or less 145%) better at full screen anti-aliasing than the Radeon R7 M260X, and also capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 460		16200 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 9600 (145%)

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 megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
