GeForce GTX 460 SE vs GeForce RTX 3080

Intro

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

The GeForce RTX 3080 is a lot (more or less 1155%) better at texture filtering than the GeForce GTX 460 SE. (explain)

GeForce RTX 3080		391680 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 360480 (1155%)

Pixel Rate

The GeForce RTX 3080 should be quite a bit (about 565%) more effective at AA than the GeForce GTX 460 SE, and will be able to handle higher resolutions while still performing well. (explain)

GeForce RTX 3080		138240 Mpixels/sec
GeForce GTX 460 SE		20800 Mpixels/sec
	Difference: 117440 (565%)

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 largest amount of data (counted in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units of the card by the core 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 applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
