GeForce GTX 465 vs GeForce RTX 3080

Intro

Compare those specs to the GeForce RTX 3080, which uses a 8 nm design. nVidia has clocked the core speed at 1440 MHz. The GDDR6X memory works at a speed of 1188 MHz on this model. It features 8704 SPUs along with 272 Texture Address Units and 96 ROPs.

GeForce GTX 465		200 Watts
GeForce RTX 3080		320 Watts
	Difference: 120 Watts (60%)

Memory Bandwidth

The GeForce RTX 3080 should in theory perform much faster than the GeForce GTX 465 in general. (explain)

GeForce RTX 3080		778547 MB/sec
GeForce GTX 465		102592 MB/sec
	Difference: 675955 (659%)

Texel Rate

The GeForce RTX 3080 should be quite a bit (approximately 1367%) better at texture filtering than the GeForce GTX 465. (explain)

GeForce RTX 3080		391680 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 364972 (1367%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce RTX 3080 is superior to the GeForce GTX 465, and very much so. (explain)

GeForce RTX 3080		138240 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 118816 (612%)

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 megabytes per second) that can be transported 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. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount 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 fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
