GeForce GTX 460 2GB vs Radeon R9 M265X

Intro

Compare that to the Radeon R9 M265X, which makes use of a 28 nm design. AMD has clocked the core speed at 575 MHz. The GDDR5 memory is set to run at a speed of 1125 MHz on this specific model. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 460 2GB should in theory perform quite a bit faster than the Radeon R9 M265X in general. (explain)

GeForce GTX 460 2GB		115200 MB/sec
Radeon R9 M265X		72000 MB/sec
	Difference: 43200 (60%)

Texel Rate

The GeForce GTX 460 2GB will be much (about 64%) faster with regards to texture filtering than the Radeon R9 M265X. (explain)

GeForce GTX 460 2GB		37800 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 14800 (64%)

Pixel Rate

The GeForce GTX 460 2GB will be quite a bit (more or less 135%) better at FSAA than the Radeon R9 M265X, and also able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 460 2GB		21600 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 12400 (135%)

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 max amount of data (counted in MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
