GeForce GT 320 vs Radeon R7 370 2G

Intro

Compare that to the Radeon R7 370 2G, which uses a 28 nm design. AMD has set the core speed at 975 MHz. The GDDR5 RAM runs at a frequency of 1400 MHz on this particular model. It features 1024 SPUs as well as 64 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320		43 Watts
Radeon R7 370 2G		110 Watts
	Difference: 67 Watts (156%)

Memory Bandwidth

Theoretically speaking, the Radeon R7 370 2G is 609% quicker than the GeForce GT 320 in general, because of its greater bandwidth. (explain)

Radeon R7 370 2G		179200 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 153920 (609%)

Texel Rate

The Radeon R7 370 2G should be much (more or less 381%) more effective at AF than the GeForce GT 320. (explain)

Radeon R7 370 2G		62400 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 49440 (381%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R7 370 2G is the winner, by a large margin. (explain)

Radeon R7 370 2G		31200 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 26880 (622%)

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 (in units of megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
