GeForce GTX 460 vs Radeon R7 M260X

Intro

Compare all that to the Radeon R7 M260X, which features GPU clock speed of 825 MHz, and 2048 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also is made up of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 460 should theoretically perform quite a bit faster than the Radeon R7 M260X in general. (explain)

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

Texel Rate

The GeForce GTX 460 will be much (approximately 91%) more effective at anisotropic filtering 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 is quite a bit (more or less 145%) faster with regards to full screen anti-aliasing than the Radeon R7 M260X, and should be capable of handling higher screen resolutions without slowing down too much. (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: Bandwidth is the largest amount of data (measured in MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to 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 max fill rate.
