GeForce GTX 465 vs Radeon R7 260X

Intro

Compare that to the Radeon R7 260X, which has a GPU core clock speed of 1100 MHz, and 2048 MB of GDDR5 memory set to run at 1625 MHz through a 128-bit bus. It also is comprised of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Power Consumption (Max TDP)

Radeon R7 260X		115 Watts
GeForce GTX 465		200 Watts
	Difference: 85 Watts (74%)

Memory Bandwidth

Theoretically speaking, the Radeon R7 260X should perform a small bit faster than the GeForce GTX 465 in general. (explain)

Radeon R7 260X		104000 MB/sec
GeForce GTX 465		102592 MB/sec
	Difference: 1408 (1%)

Texel Rate

The Radeon R7 260X is much (more or less 131%) faster with regards to AF than the GeForce GTX 465. (explain)

Radeon R7 260X		61600 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 34892 (131%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 465 is a better choice, but only just. (explain)

GeForce GTX 465		19424 Mpixels/sec
Radeon R7 260X		17600 Mpixels/sec
	Difference: 1824 (10%)

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 max amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 can be 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 higher this number, the better the 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 most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
