GeForce 8800 GT 512MB vs Radeon RX 6800

Intro

The GeForce 8800 GT 512MB has a core clock speed of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 256-bit bus, and uses a 65 nm design. It is made up of 112 SPUs, 56 Texture Address Units, and 16 ROPs.

Compare that to the Radeon RX 6800, which uses a 7 nm design. AMD has clocked the core speed at 1700 MHz. The GDDR6 RAM works at a frequency of 2000 MHz on this specific model. It features 3840 SPUs as well as 240 Texture Address Units and 96 Rasterization Operator Units.

GeForce 8800 GT 512MB 105 Watts
Radeon RX 6800 250 Watts
Difference: 145 Watts (138%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6800 is 810% quicker than the GeForce 8800 GT 512MB overall, because of its higher data rate. (explain)

Radeon RX 6800 524288 MB/sec
GeForce 8800 GT 512MB 57600 MB/sec
Difference: 466688 (810%)

Texel Rate

The Radeon RX 6800 should be quite a bit (more or less 1114%) faster with regards to anisotropic filtering than the GeForce 8800 GT 512MB. (explain)

Radeon RX 6800 408000 Mtexels/sec
GeForce 8800 GT 512MB 33600 Mtexels/sec
Difference: 374400 (1114%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6800 is the winner, by a large margin. (explain)

Radeon RX 6800 163200 Mpixels/sec
GeForce 8800 GT 512MB 9600 Mpixels/sec
Difference: 153600 (1600%)

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 maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 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 AA, HDR and higher screen 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 clock 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. 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 rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
