GeForce GT 320 vs Radeon R7 250X

Intro

Compare all that to the Radeon R7 250X, which features GPU clock speed of 1000 MHz, and 1024 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320		43 Watts
Radeon R7 250X		95 Watts
	Difference: 52 Watts (121%)

Memory Bandwidth

The Radeon R7 250X should theoretically be much faster than the GeForce GT 320 overall. (explain)

Radeon R7 250X		72000 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 46720 (185%)

Texel Rate

The Radeon R7 250X will be much (more or less 209%) faster with regards to texture filtering than the GeForce GT 320. (explain)

Radeon R7 250X		40000 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 27040 (209%)

Pixel Rate

The Radeon R7 250X should be quite a bit (more or less 270%) more effective at full screen anti-aliasing than the GeForce GT 320, and also will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon R7 250X		16000 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 11680 (270%)

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 max amount of data (measured in MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If 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 are applied in one second. This number is calculated by multiplying the total texture units 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 maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
