GeForce GT 320 vs Radeon R7 250X

Intro

Compare those specs to the Radeon R7 250X, which makes use of a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 memory works at a frequency of 1125 MHz on this card. It features 640 SPUs along with 40 TAUs and 16 ROPs.

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

Memory Bandwidth

In theory, the Radeon R7 250X should perform a lot 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 should be quite a bit (about 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

If running with a high resolution is important to you, then the Radeon R7 250X is a better choice, by a large margin. (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: Bandwidth is the max amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range 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 worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
