GeForce RTX 3080 vs GeForce RTX 3090

Intro

Compare that to the GeForce RTX 3090, which has a core clock speed of 1395 MHz and a GDDR6X memory frequency of 1219 MHz. It also features a 384-bit memory bus, and uses a 8 nm design. It is comprised of 10496 SPUs, 328 Texture Address Units, and 112 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3080		320 Watts
GeForce RTX 3090		350 Watts
	Difference: 30 Watts (9%)

Memory Bandwidth

In theory, the GeForce RTX 3090 is 23% quicker than the GeForce RTX 3080 in general, because of its greater bandwidth. (explain)

GeForce RTX 3090		958668 MB/sec
GeForce RTX 3080		778547 MB/sec
	Difference: 180121 (23%)

Texel Rate

The GeForce RTX 3090 will be a small bit (more or less 17%) faster with regards to anisotropic filtering than the GeForce RTX 3080. (explain)

GeForce RTX 3090		457560 Mtexels/sec
GeForce RTX 3080		391680 Mtexels/sec
	Difference: 65880 (17%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce RTX 3090 is a better choice, not by a very large margin though. (explain)

GeForce RTX 3090		156240 Mpixels/sec
GeForce RTX 3080		138240 Mpixels/sec
	Difference: 18000 (13%)

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 max amount of data (counted in MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core 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 also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
