GeForce GTX 460 SE vs Radeon R7 M265

Intro

Compare all that to the Radeon R7 M265, which makes use of a 28 nm design. AMD has clocked the core frequency at 725 MHz. The DDR3 memory runs at a frequency of 1000 MHz on this particular card. It features 384 SPUs along with 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 460 SE should theoretically be quite a bit faster than the Radeon R7 M265 overall. (explain)

GeForce GTX 460 SE		108800 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 76800 (240%)

Texel Rate

The GeForce GTX 460 SE will be much (about 79%) better at anisotropic filtering than the Radeon R7 M265. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 13800 (79%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 460 SE is superior to the Radeon R7 M265, by far. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 15000 (259%)

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 maximum amount of data (counted in MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units 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 maximum amount of pixels that the graphics chip could possibly write 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 - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
