GeForce 8800 Ultra vs Radeon R7 260X

Intro

The GeForce 8800 Ultra uses a 90 nm design. nVidia has set the core frequency at 612 MHz. The GDDR3 RAM is set to run at a frequency of 1080 MHz on this specific model. It features 128 SPUs as well as 64 TAUs and 24 Rasterization Operator Units.

Compare all of that to the Radeon R7 260X, which has clock speeds of 1100 MHz on the GPU, and 1625 MHz on the 2048 MB of GDDR5 memory. It features 896 SPUs along with 56 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 260X 115 Watts
GeForce 8800 Ultra 171 Watts
Difference: 56 Watts (49%)

Memory Bandwidth

In theory, the Radeon R7 260X should perform a bit faster than the GeForce 8800 Ultra in general. (explain)

Radeon R7 260X 104000 MB/sec
GeForce 8800 Ultra 103680 MB/sec
Difference: 320 (0%)

Texel Rate

The Radeon R7 260X should be a lot (more or less 57%) more effective at anisotropic filtering than the GeForce 8800 Ultra. (explain)

Radeon R7 260X 61600 Mtexels/sec
GeForce 8800 Ultra 39168 Mtexels/sec
Difference: 22432 (57%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 260X is the winner, but it probably won't make a huge difference. (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.

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at 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 could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
