GeForce GT 320 vs Radeon R7 M260X

Intro

Compare all of that to the Radeon R7 M260X, which has core clock speeds of 825 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 memory. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M260X is 153% quicker than the GeForce GT 320 overall, because of its higher data rate. (explain)

Radeon R7 M260X		64000 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 38720 (153%)

Texel Rate

The Radeon R7 M260X is much (about 53%) faster with regards to texture filtering than the GeForce GT 320. (explain)

Radeon R7 M260X		19800 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 6840 (53%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R7 M260X is superior to the GeForce GT 320, and very much so. (explain)

Radeon R7 M260X		6600 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 2280 (53%)

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 megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core 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 output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
