GeForce GTX 460 2GB vs Radeon R7 M260

Intro

Compare that to the Radeon R7 M260, which makes use of a 28 nm design. AMD has set the core speed at 715 MHz. The DDR3 memory is set to run at a speed of 1000 MHz on this particular card. It features 384 SPUs as well as 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 460 2GB will be 620% faster than the Radeon R7 M260 overall, due to its greater data rate. (explain)

GeForce GTX 460 2GB		115200 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 99200 (620%)

Texel Rate

The GeForce GTX 460 2GB should be quite a bit (about 120%) faster with regards to anisotropic filtering than the Radeon R7 M260. (explain)

GeForce GTX 460 2GB		37800 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 20640 (120%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 460 2GB is the winner, by far. (explain)

GeForce GTX 460 2GB		21600 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 15880 (278%)

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 MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number 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 filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
