GeForce GT 320 vs Radeon R7 250

Intro

Compare all that to the Radeon R7 250, which has core clock speeds of 1000 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320		43 Watts
Radeon R7 250		65 Watts
	Difference: 22 Watts (51%)

Memory Bandwidth

The Radeon R7 250 should in theory be a lot faster than the GeForce GT 320 overall. (explain)

Radeon R7 250		73600 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 48320 (191%)

Texel Rate

The Radeon R7 250 will be quite a bit (about 85%) better at anisotropic filtering than the GeForce GT 320. (explain)

Radeon R7 250		24000 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 11040 (85%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R7 250 is a better choice, by far. (explain)

Radeon R7 250		8000 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 3680 (85%)

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 largest amount of data (measured in megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
