GeForce GTX 460 vs Radeon R7 M260X

Intro

Compare those specs to the Radeon R7 M260X, which makes use of a 28 nm design. AMD has set the core frequency at 825 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this card. It features 384 SPUs along with 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 460 should theoretically be quite a bit better 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 is quite a bit (about 91%) faster with regards to texture filtering than the Radeon R7 M260X. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 460 is the winner, and very much so. (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 maximum amount of information (in units of megabytes per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
