GeForce 8600 GT 512MB DDR2 vs GeForce RTX 2080 Ti

Intro

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

Compare all that to the GeForce RTX 2080 Ti, which features a GPU core clock speed of 1350 MHz, and 11264 MB of GDDR6 RAM set to run at 1750 MHz through a 352-bit bus. It also is made up of 4352 Stream Processors, 272 Texture Address Units, and 88 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the 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 that the graphics card could 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 Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
