GeForce GTX 460 SE vs Radeon R9 M270X

Intro

Compare those specifications to the Radeon R9 M270X, which makes use of a 28 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 RAM is set to run at a speed of 1125 MHz on this particular card. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GTX 460 SE should perform quite a bit faster than the Radeon R9 M270X overall. (explain)

GeForce GTX 460 SE		108800 MB/sec
Radeon R9 M270X		72000 MB/sec
	Difference: 36800 (51%)

Texel Rate

The GeForce GTX 460 SE is just a bit (approximately 8%) faster with regards to texture filtering than the Radeon R9 M270X. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
Radeon R9 M270X		29000 Mtexels/sec
	Difference: 2200 (8%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 460 SE is superior to the Radeon R9 M270X, by far. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon R9 M270X		11600 Mpixels/sec
	Difference: 9200 (79%)

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 largest amount of information (measured in megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
