GeForce GT 320 vs Radeon R7 250X

Intro

Compare that to the Radeon R7 250X, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 memory works at a frequency of 1125 MHz on this card. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator 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

Performance-wise, the Radeon R7 250X should in theory be a lot superior to 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 quite a bit (more or less 209%) better at anisotropic 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 using a high screen resolution is important to you, then the Radeon R7 250X is superior to the GeForce GT 320, and very much so. (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 maximum amount of information (in units of MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
