GeForce GTX 480 vs GeForce RTX 3080

Intro

Compare those specifications to the GeForce RTX 3080, which uses a 8 nm design. nVidia has set the core frequency at 1440 MHz. The GDDR6X RAM runs at a speed of 1188 MHz on this specific model. It features 8704 SPUs along with 272 TAUs and 96 Rasterization Operator Units.

GeForce GTX 480		177408 MB/sec
	Difference: 601139 (339%)

Texel Rate

The GeForce RTX 3080 will be a lot (more or less 833%) better at AF than the GeForce GTX 480. (explain)

GeForce RTX 3080		391680 Mtexels/sec
GeForce GTX 480		42000 Mtexels/sec
	Difference: 349680 (833%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce RTX 3080 is the winner, and very much so. (explain)

GeForce RTX 3080		138240 Mpixels/sec
GeForce GTX 480		33600 Mpixels/sec
	Difference: 104640 (311%)

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 maximum amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher 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 the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
