GeForce 8600 GT 512MB DDR2 vs GeForce RTX 3080

Intro

The GeForce 8600 GT 512MB DDR2 comes with a GPU core speed of 540 MHz, and the 512 MB of DDR2 memory runs at 400 MHz through a 128-bit bus. It also features 32 Stream Processors, 16 Texture Address Units, and 8 Raster Operation Units.

Compare those specs to the GeForce RTX 3080, which features clock speeds of 1440 MHz on the GPU, and 1188 MHz on the 10240 MB of GDDR6X memory. It features 8704 SPUs along with 272 TAUs and 96 Rasterization Operator Units.

GeForce RTX 3080 778547 MB/sec
GeForce 8600 GT 512MB DDR2 12800 MB/sec
Difference: 765747 (5982%)

Texel Rate

The GeForce RTX 3080 is quite a bit (approximately 4433%) faster with regards to texture filtering than the GeForce 8600 GT 512MB DDR2. (explain)

GeForce RTX 3080 391680 Mtexels/sec
GeForce 8600 GT 512MB DDR2 8640 Mtexels/sec
Difference: 383040 (4433%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce RTX 3080 is a better choice, by a large margin. (explain)

GeForce RTX 3080 138240 Mpixels/sec
GeForce 8600 GT 512MB DDR2 4320 Mpixels/sec
Difference: 133920 (3100%)

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 maximum amount of data (in units of MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that can be processed in one second. This figure is calculated 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 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 graphics card can possibly write 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 clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
