GeForce GTX 260 vs Radeon R7 260X

Intro

Compare that to the Radeon R7 260X, which uses a 28 nm design. AMD has clocked the core speed at 1100 MHz. The GDDR5 RAM is set to run at a speed of 1625 MHz on this particular card. It features 896 SPUs along with 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 260X		115 Watts
GeForce GTX 260		182 Watts
	Difference: 67 Watts (58%)

Memory Bandwidth

The GeForce GTX 260 should in theory perform a small bit faster than the Radeon R7 260X in general. (explain)

GeForce GTX 260		111888 MB/sec
Radeon R7 260X		104000 MB/sec
	Difference: 7888 (8%)

Texel Rate

The Radeon R7 260X is quite a bit (more or less 67%) more effective at AF than the GeForce GTX 260. (explain)

Radeon R7 260X		61600 Mtexels/sec
GeForce GTX 260		36864 Mtexels/sec
	Difference: 24736 (67%)

Pixel Rate

If running with lots of anti-aliasing 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		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: Bandwidth is the maximum amount of data (counted in MB per second) that can be transferred across 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, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
