VS

GeForce 8800 GS vs Radeon HD 4670 1GB

Intro

The GeForce 8800 GS features clock speeds of 550 MHz on the GPU, and 800 MHz on the 384 MB of GDDR3 RAM. It features 96 SPUs as well as 48 Texture Address Units and 12 ROPs.

Compare all of that to the Radeon HD 4670 1GB, which has a core clock frequency of 750 MHz and a GDDR4/GDDR3/DDR3/DDR2 memory speed of 1100 MHz. It also uses a 128-bit bus, and makes use of a 55 nm design. It is comprised of 320(64x5) SPUs, 32 Texture Address Units, and 8 Raster Operation Units.

The GeForce 8800 GS should be a small bit (about 10%) more effective at anisotropic filtering than the Radeon HD 4670 1GB. (explain)

GeForce 8800 GS 26400 Mtexels/sec
Radeon HD 4670 1GB 24000 Mtexels/sec
Difference: 2400 (10%)

Pixel Rate

The GeForce 8800 GS will be just a bit (more or less 10%) more effective at FSAA than the Radeon HD 4670 1GB, and will be able to handle higher resolutions without losing too much performance. (explain)

GeForce 8800 GS 6600 Mpixels/sec
Radeon HD 4670 1GB 6000 Mpixels/sec
Difference: 600 (10%)

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 data (counted in MB per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
