GeForce GTX 460 SE vs Radeon R7 250X

Intro

Compare those specs to the Radeon R7 250X, which features GPU clock speed of 1000 MHz, and 1024 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250X		95 Watts
GeForce GTX 460 SE		150 Watts
	Difference: 55 Watts (58%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 SE is 51% quicker than the Radeon R7 250X overall, due to its higher bandwidth. (explain)

GeForce GTX 460 SE		108800 MB/sec
Radeon R7 250X		72000 MB/sec
	Difference: 36800 (51%)

Texel Rate

The Radeon R7 250X will be quite a bit (more or less 28%) more effective at anisotropic filtering than the GeForce GTX 460 SE. (explain)

Radeon R7 250X		40000 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 8800 (28%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 460 SE is a better choice, by far. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon R7 250X		16000 Mpixels/sec
	Difference: 4800 (30%)

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 maximum amount of information (counted 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. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
