GeForce GTX 260 Core 216 vs Radeon R7 260X

Intro

Compare those specs to the Radeon R7 260X, which uses a 28 nm design. AMD has clocked the core frequency at 1100 MHz. The GDDR5 memory runs at a frequency of 1625 MHz on this specific model. It features 896 SPUs as well as 56 Texture Address Units and 16 ROPs.

Radeon R7 260X		104000 MB/sec
	Difference: 7888 (8%)

Texel Rate

The Radeon R7 260X should be quite a bit (more or less 49%) more effective at texture filtering than the GeForce GTX 260 Core 216. (explain)

Radeon R7 260X		61600 Mtexels/sec
GeForce GTX 260 Core 216		41472 Mtexels/sec
	Difference: 20128 (49%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R7 260X is the winner, though only just barely. (explain)

Radeon R7 260X		17600 Mpixels/sec
GeForce GTX 260 Core 216		16128 Mpixels/sec
	Difference: 1472 (9%)

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 information (counted in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units by the core clock 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 in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. 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 output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
