GeForce GT 310 vs Radeon R7 250

Intro

Compare all of that to the Radeon R7 250, which comes with clock speeds of 1000 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs as well as 24 TAUs and 8 ROPs.

GeForce GT 310		31 Watts
Radeon R7 250		65 Watts
	Difference: 34 Watts (110%)

Memory Bandwidth

Theoretically, the Radeon R7 250 should perform a lot faster than the GeForce GT 310 in general. (explain)

Radeon R7 250		73600 MB/sec
GeForce GT 310		16000 MB/sec
	Difference: 57600 (360%)

Texel Rate

The Radeon R7 250 should be quite a bit (approximately 409%) better at anisotropic filtering than the GeForce GT 310. (explain)

Radeon R7 250		24000 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 19288 (409%)

Pixel Rate

The Radeon R7 250 is much (approximately 240%) more effective at anti-aliasing than the GeForce GT 310, and also able to handle higher resolutions more effectively. (explain)

Radeon R7 250		8000 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 5644 (240%)

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 information (counted in MB per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, 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 maximum amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
