GeForce 8800 GTS (G80) 320MB vs Radeon HD 3850 1GB

Intro

The GeForce 8800 GTS (G80) 320MB comes with core clock speeds of 513 MHz on the GPU, and 792 MHz on the 320 MB of GDDR3 RAM. It features 96 SPUs as well as 48 TAUs and 20 ROPs.

Compare all of that to the Radeon HD 3850 1GB, which features GPU core speed of 668 MHz, and 1024 MB of GDDR3 RAM running at 828 MHz through a 256-bit bus. It also features 320(64x5) Stream Processors, 16 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 3850 1GB 75 Watts
GeForce 8800 GTS (G80) 320MB 143 Watts
Difference: 68 Watts (91%)

Memory Bandwidth

In theory, the GeForce 8800 GTS (G80) 320MB should be 20% faster than the Radeon HD 3850 1GB in general, because of its higher bandwidth. (explain)

GeForce 8800 GTS (G80) 320MB 63360 MB/sec
Radeon HD 3850 1GB 52992 MB/sec
Difference: 10368 (20%)

Texel Rate

The GeForce 8800 GTS (G80) 320MB will be much (more or less 130%) faster with regards to AF than the Radeon HD 3850 1GB. (explain)

GeForce 8800 GTS (G80) 320MB 24624 Mtexels/sec
Radeon HD 3850 1GB 10688 Mtexels/sec
Difference: 13936 (130%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 3850 1GB is superior to the GeForce 8800 GTS (G80) 320MB, not by a very large margin though. (explain)

Radeon HD 3850 1GB 10688 Mpixels/sec
GeForce 8800 GTS (G80) 320MB 10260 Mpixels/sec
Difference: 428 (4%)

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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If 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 amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
