GeForce GT 315 vs Radeon R7 260X

Intro

Compare all of that to the Radeon R7 260X, which makes use of a 28 nm design. AMD has set the core frequency at 1100 MHz. The GDDR5 RAM is set to run at a frequency of 1625 MHz on this particular model. It features 896 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.

GeForce GT 315		52 Watts
Radeon R7 260X		115 Watts
	Difference: 63 Watts (121%)

Memory Bandwidth

In theory, the Radeon R7 260X should perform much faster than the GeForce GT 315 overall. (explain)

Radeon R7 260X		104000 MB/sec
GeForce GT 315		25280 MB/sec
	Difference: 78720 (311%)

Texel Rate

The Radeon R7 260X should be much (approximately 516%) faster with regards to anisotropic filtering than the GeForce GT 315. (explain)

Radeon R7 260X		61600 Mtexels/sec
GeForce GT 315		10000 Mtexels/sec
	Difference: 51600 (516%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R7 260X is superior to the GeForce GT 315, and very much so. (explain)

Radeon R7 260X		17600 Mpixels/sec
GeForce GT 315		5000 Mpixels/sec
	Difference: 12600 (252%)

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 (measured in MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. 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 quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
