GeForce 8800 Ultra vs Radeon HD 7790

Intro

The GeForce 8800 Ultra comes with a GPU clock speed of 612 MHz, and the 768 MB of GDDR3 RAM 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 Raster Operation Units.

Compare those specs to the Radeon HD 7790, which features a GPU core clock speed of 1000 MHz, and 1024 MB of GDDR5 RAM running at 1500 MHz through a 128-bit bus. It also is made up of 896 SPUs, 56 TAUs, and 16 ROPs.

Radeon HD 7790 96000 MB/sec
Difference: 7680 (8%)

Texel Rate

The Radeon HD 7790 will be a lot (more or less 43%) better at texture filtering than the GeForce 8800 Ultra. (explain)

Radeon HD 7790 56000 Mtexels/sec
GeForce 8800 Ultra 39168 Mtexels/sec
Difference: 16832 (43%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon HD 7790 is a better choice, though only just barely. (explain)

Radeon HD 7790 16000 Mpixels/sec
GeForce 8800 Ultra 14688 Mpixels/sec
Difference: 1312 (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.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If 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 number of 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 higher the texel rate, the better the 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 amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
