GeForce GT 320 vs Radeon R7 250X

Intro

Compare all that to the Radeon R7 250X, which has a clock speed of 1000 MHz and a GDDR5 memory frequency of 1125 MHz. It also features a 128-bit bus, and makes use of a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Texel Rate

The Radeon R7 250X is a lot (about 209%) faster with regards to AF 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 will be much (more or less 270%) better at FSAA than the GeForce GT 320, and will be able to handle higher screen resolutions without slowing down too much. (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 transferred across the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
