GeForce GT 315 vs Radeon R7 M260X

Intro

Compare all of that to the Radeon R7 M260X, which makes use of a 28 nm design. AMD has clocked the core speed at 825 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this particular card. It features 384 SPUs along with 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 M260X should theoretically perform quite a bit faster than the GeForce GT 315 in general. (explain)

Radeon R7 M260X		64000 MB/sec
GeForce GT 315		25280 MB/sec
	Difference: 38720 (153%)

Texel Rate

The Radeon R7 M260X is much (about 98%) more effective at texture filtering than the GeForce GT 315. (explain)

Radeon R7 M260X		19800 Mtexels/sec
GeForce GT 315		10000 Mtexels/sec
	Difference: 9800 (98%)

Pixel Rate

The Radeon R7 M260X will be a lot (more or less 32%) better at FSAA than the GeForce GT 315, and also capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon R7 M260X		6600 Mpixels/sec
GeForce GT 315		5000 Mpixels/sec
	Difference: 1600 (32%)

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 (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units of the card by the core clock 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
