GeForce 8600 GT 512MB DDR2 vs GeForce RTX 4080

Intro

Compare those specs to the GeForce RTX 4080, which features GPU clock speed of 2205 MHz, and 16384 MB of GDDR6X RAM set to run at 1400 MHz through a 256-bit bus. It also features 9728 SPUs, 304 Texture Address Units, and 112 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 512MB DDR2		47 Watts
GeForce RTX 4080		320 Watts
	Difference: 273 Watts (581%)

Memory Bandwidth

The GeForce RTX 4080 should in theory perform quite a bit faster than the GeForce 8600 GT 512MB DDR2 overall. (explain)

GeForce RTX 4080		734003 MB/sec
GeForce 8600 GT 512MB DDR2		12800 MB/sec
	Difference: 721203 (5634%)

Texel Rate

The GeForce RTX 4080 will be a lot (about 7658%) faster with regards to anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)

GeForce RTX 4080		670320 Mtexels/sec
GeForce 8600 GT 512MB DDR2		8640 Mtexels/sec
	Difference: 661680 (7658%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 4080 is a better choice, by far. (explain)

GeForce RTX 4080		246960 Mpixels/sec
GeForce 8600 GT 512MB DDR2		4320 Mpixels/sec
	Difference: 242640 (5617%)

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 max amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics 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 the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
