GeForce 8800 Ultra vs Radeon R7 260X

Intro

The GeForce 8800 Ultra has a GPU core speed of 612 MHz, and the 768 MB of GDDR3 memory is set to run at 1080 MHz through a 384-bit bus. It also is made up of 128 Stream Processors, 64 TAUs, and 24 ROPs.

Compare all of that to the Radeon R7 260X, which makes use of a 28 nm design. AMD has clocked the core speed at 1100 MHz. The GDDR5 memory works at a speed of 1625 MHz on this particular card. It features 896 SPUs along with 56 Texture Address Units 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

Theoretically, the Radeon R7 260X should be a small 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 is a lot (more or less 57%) better at texture 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 using lots of anti-aliasing is important to you, then the Radeon R7 260X is the winner, though not by far. (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 largest amount of information (measured in megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 applied in one second. This 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
