GeForce 8600 GT 1GB GDDR3 vs Radeon RX 5700 XT

Intro

The GeForce 8600 GT 1GB GDDR3 makes use of a 80 nm design. nVidia has set the core frequency at 540 MHz. The GDDR3 RAM is set to run at a frequency of 700 MHz on this card. It features 32 SPUs as well as 16 TAUs and 8 ROPs.

Compare that to the Radeon RX 5700 XT, which comes with a GPU core clock speed of 1605 MHz, and 8096 MB of GDDR6 RAM set to run at 1750 MHz through a 256-bit bus. It also is comprised of 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

Pixel Rate

The Radeon RX 5700 XT should be quite a bit (approximately 2278%) better at full screen anti-aliasing than the GeForce 8600 GT 1GB GDDR3, and should be able to handle higher screen resolutions more effectively. (explain)

Radeon RX 5700 XT 102720 Mpixels/sec
GeForce 8600 GT 1GB GDDR3 4320 Mpixels/sec
Difference: 98400 (2278%)

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 information (measured in MB per second) that can be transported across the external memory interface within a second. It's worked out 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 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 number 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 this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
