GeForce 8600 GT 256MB GDDR3 vs GeForce RTX 2080

Intro

Compare all that to the GeForce RTX 2080, which makes use of a 12 nm design. nVidia has clocked the core frequency at 1515 MHz. The GDDR6 RAM is set to run at a speed of 1750 MHz on this specific model. It features 2944 SPUs as well as 184 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 256MB GDDR3		47 Watts
GeForce RTX 2080		215 Watts
	Difference: 168 Watts (357%)

Memory Bandwidth

In theory, the GeForce RTX 2080 is 1948% faster than the GeForce 8600 GT 256MB GDDR3 overall, because of its greater bandwidth. (explain)

GeForce RTX 2080		458752 MB/sec
GeForce 8600 GT 256MB GDDR3		22400 MB/sec
	Difference: 436352 (1948%)

Texel Rate

The GeForce RTX 2080 will be a lot (approximately 3126%) better at AF than the GeForce 8600 GT 256MB GDDR3. (explain)

GeForce RTX 2080		278760 Mtexels/sec
GeForce 8600 GT 256MB GDDR3		8640 Mtexels/sec
	Difference: 270120 (3126%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 2080 is a better choice, and very much so. (explain)

GeForce RTX 2080		96960 Mpixels/sec
GeForce 8600 GT 256MB GDDR3		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 largest amount of data (in units of MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. 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 max fill rate.
