GeForce 8600 GT 512MB DDR2 vs GeForce RTX 2080 SUPER

Intro

Compare all that to the GeForce RTX 2080 SUPER, which makes use of a 12 nm design. nVidia has set the core frequency at 1650 MHz. The GDDR6 RAM runs at a speed of 1937 MHz on this specific model. It features 3072 SPUs along with 192 Texture Address Units and 64 ROPs.

	Difference: 495104 (3868%)

Texel Rate

The GeForce RTX 2080 SUPER is quite a bit (about 3567%) better at anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce 8600 GT 512MB DDR2		8640 Mtexels/sec
	Difference: 308160 (3567%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 2080 SUPER is the winner, by a large margin. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce 8600 GT 512MB DDR2		4320 Mpixels/sec
	Difference: 101280 (2344%)

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: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's 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 - the lower the bandwidth is, the lower the ability to get to the max fill rate.
