GeForce 8600 GT 1GB GDDR3 vs Radeon RX 6900 XT

Intro

The GeForce 8600 GT 1GB GDDR3 has core speeds of 540 MHz on the GPU, and 700 MHz on the 1024 MB of GDDR3 memory. It features 32 SPUs along with 16 Texture Address Units and 8 ROPs.

Compare all of that to the Radeon RX 6900 XT, which has a core clock frequency of 1825 MHz and a GDDR6 memory frequency of 2000 MHz. It also makes use of a 256-bit bus, and uses a 7 nm design. It features 5120 SPUs, 320 Texture Address Units, and 128 Raster Operation Units.

Radeon RX 6900 XT 524288 MB/sec
GeForce 8600 GT 1GB GDDR3 22400 MB/sec
Difference: 501888 (2241%)

Texel Rate

The Radeon RX 6900 XT should be much (more or less 6659%) better at texture filtering than the GeForce 8600 GT 1GB GDDR3. (explain)

Radeon RX 6900 XT 584000 Mtexels/sec
GeForce 8600 GT 1GB GDDR3 8640 Mtexels/sec
Difference: 575360 (6659%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6900 XT is a better choice, by far. (explain)

Radeon RX 6900 XT 233600 Mpixels/sec
GeForce 8600 GT 1GB GDDR3 4320 Mpixels/sec
Difference: 229280 (5307%)

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 max amount of data (measured in megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs 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 output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
