GeForce GTX 460 2GB vs Radeon R7 M265

Intro

Compare those specifications to the Radeon R7 M265, which has core speeds of 725 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 460 2GB should theoretically perform a lot faster than the Radeon R7 M265 in general. (explain)

GeForce GTX 460 2GB		115200 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 83200 (260%)

Texel Rate

The GeForce GTX 460 2GB is much (about 117%) more effective at anisotropic filtering than the Radeon R7 M265. (explain)

GeForce GTX 460 2GB		37800 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 20400 (117%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 460 2GB is a better choice, and very much so. (explain)

GeForce GTX 460 2GB		21600 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 15800 (272%)

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 (in units of MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory 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 better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling 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 record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
