GeForce 8800 Ultra vs Radeon R7 260X

Intro

Compare all of that to the Radeon R7 260X, which uses a 28 nm design. AMD has clocked the core frequency at 1100 MHz. The GDDR5 RAM runs at a speed of 1625 MHz on this specific card. It features 896 SPUs as well as 56 TAUs and 16 ROPs.

GeForce 8800 Ultra		39168 Mtexels/sec
	Difference: 22432 (57%)

Pixel Rate

The Radeon R7 260X should be a small bit (more or less 20%) faster with regards to FSAA than the GeForce 8800 Ultra, and also will be able to handle higher resolutions while still performing well. (explain)

Radeon R7 260X		17600 Mpixels/sec
GeForce 8800 Ultra		14688 Mpixels/sec
	Difference: 2912 (20%)

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 (in units of megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 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, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
