GeForce 8600 GT 1GB DDR2 vs GeForce RTX 2060 Super

Intro

Compare all that to the GeForce RTX 2060 Super, which features a clock frequency of 1470 MHz and a GDDR6 memory frequency of 1750 MHz. It also uses a 256-bit bus, and makes use of a 12 nm design. It features 2176 SPUs, 136 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 1GB DDR2		47 Watts
GeForce RTX 2060 Super		175 Watts
	Difference: 128 Watts (272%)

Memory Bandwidth

In theory, the GeForce RTX 2060 Super should be 3484% faster than the GeForce 8600 GT 1GB DDR2 overall, because of its higher data rate. (explain)

GeForce RTX 2060 Super		458752 MB/sec
GeForce 8600 GT 1GB DDR2		12800 MB/sec
	Difference: 445952 (3484%)

Texel Rate

The GeForce RTX 2060 Super is much (approximately 2214%) more effective at AF than the GeForce 8600 GT 1GB DDR2. (explain)

GeForce RTX 2060 Super		199920 Mtexels/sec
GeForce 8600 GT 1GB DDR2		8640 Mtexels/sec
	Difference: 191280 (2214%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 2060 Super is a better choice, and very much so. (explain)

GeForce RTX 2060 Super		94080 Mpixels/sec
GeForce 8600 GT 1GB DDR2		4320 Mpixels/sec
	Difference: 89760 (2078%)

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 maximum amount of information (measured in megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels 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. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few 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.
