VS

GeForce 8600 GT 1GB GDDR3 vs Radeon RX 6900 XT

Intro

The GeForce 8600 GT 1GB GDDR3 uses a 80 nm design. nVidia has set the core frequency at 540 MHz. The GDDR3 memory is set to run at a speed of 700 MHz on this card. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.

Compare all of that to the Radeon RX 6900 XT, which has GPU clock speed of 1825 MHz, and 16384 MB of GDDR6 memory running at 2000 MHz through a 256-bit bus. It also features 5120 SPUs, 320 Texture Address Units, and 128 Raster Operation Units.

GeForce 8600 GT 1GB GDDR3 22400 MB/sec
Difference: 501888 (2241%)

Texel Rate

The Radeon RX 6900 XT should be much (about 6659%) faster with regards to AF 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 using lots of anti-aliasing is important to you, then the Radeon RX 6900 XT is superior to the GeForce 8600 GT 1GB GDDR3, 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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

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