GeForce 8600 GT 1GB GDDR3 vs GeForce RTX 3080

Intro

Compare all that to the GeForce RTX 3080, which has a clock speed of 1440 MHz and a GDDR6X memory frequency of 1188 MHz. It also makes use of a 320-bit bus, and uses a 8 nm design. It is made up of 8704 SPUs, 272 TAUs, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 1GB GDDR3		47 Watts
GeForce RTX 3080		320 Watts
	Difference: 273 Watts (581%)

Memory Bandwidth

In theory, the GeForce RTX 3080 will be 3376% quicker than the GeForce 8600 GT 1GB GDDR3 in general, because of its greater bandwidth. (explain)

GeForce RTX 3080		778547 MB/sec
GeForce 8600 GT 1GB GDDR3		22400 MB/sec
	Difference: 756147 (3376%)

Texel Rate

The GeForce RTX 3080 is a lot (about 4433%) more effective at anisotropic filtering than the GeForce 8600 GT 1GB GDDR3. (explain)

GeForce RTX 3080		391680 Mtexels/sec
GeForce 8600 GT 1GB GDDR3		8640 Mtexels/sec
	Difference: 383040 (4433%)

Pixel Rate

The GeForce RTX 3080 is a lot (about 3100%) faster with regards to FSAA than the GeForce 8600 GT 1GB GDDR3, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce RTX 3080		138240 Mpixels/sec
GeForce 8600 GT 1GB GDDR3		4320 Mpixels/sec
	Difference: 133920 (3100%)

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 information (measured in megabytes per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. 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 rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
