GeForce GTX 460 SE vs Radeon R7 250X

Intro

Compare those specifications to the Radeon R7 250X, which comes with core clock speeds of 1000 MHz on the GPU, and 1125 MHz on the 1024 MB of GDDR5 memory. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator 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, the GeForce GTX 460 SE should be quite a bit faster than the Radeon R7 250X in general. (explain)

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

Texel Rate

The Radeon R7 250X should be much (more or less 28%) more effective at texture 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

The GeForce GTX 460 SE will be quite a bit (about 30%) more effective at anti-aliasing than the Radeon R7 250X, and also should be able to handle higher resolutions while still performing well. (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: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
