GeForce 8600 GT 512MB DDR2 vs GeForce RTX 3080

Intro

The GeForce 8600 GT 512MB DDR2 has a clock speed of 540 MHz and a DDR2 memory speed of 400 MHz. It also makes use of a 128-bit memory bus, and uses a 80 nm design. It is comprised of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Compare those specs to the GeForce RTX 3080, which has a GPU core clock speed of 1440 MHz, and 10240 MB of GDDR6X memory running at 1188 MHz through a 320-bit bus. It also is made up of 8704 SPUs, 272 Texture Address Units, and 96 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher 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 one second.

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