GeForce 8600 GT 512MB DDR2 vs GeForce RTX 2080

Intro

Compare that to the GeForce RTX 2080, which has a core clock speed of 1515 MHz and a GDDR6 memory speed of 1750 MHz. It also uses a 256-bit bus, and makes use of a 12 nm design. It is made up of 2944 SPUs, 184 Texture Address Units, and 64 Raster Operation Units.

	Difference: 270120 (3126%)

Pixel Rate

The GeForce RTX 2080 will be quite a bit (approximately 2144%) more effective at FSAA than the GeForce 8600 GT 512MB DDR2, and able to handle higher resolutions more effectively. (explain)

GeForce RTX 2080		96960 Mpixels/sec
GeForce 8600 GT 512MB DDR2		4320 Mpixels/sec
	Difference: 92640 (2144%)

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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock 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 processed in one second.

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