GeForce GTX 260 Core 216 vs Radeon R7 260X

Intro

Compare those specs to the Radeon R7 260X, which has a clock speed of 1100 MHz and a GDDR5 memory speed of 1625 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 260X		115 Watts
GeForce GTX 260 Core 216		202 Watts
	Difference: 87 Watts (76%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 260 Core 216 is 8% faster than the Radeon R7 260X in general, due to its higher data rate. (explain)

GeForce GTX 260 Core 216		111888 MB/sec
Radeon R7 260X		104000 MB/sec
	Difference: 7888 (8%)

Texel Rate

The Radeon R7 260X will be quite a bit (about 49%) better at AF 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

The Radeon R7 260X should be just a bit (approximately 9%) better at FSAA than the GeForce GTX 260 Core 216, and also will be able to handle higher resolutions without slowing down too much. (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: Bandwidth is the max amount of information (counted in MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
