GeForce RTX 3080 Ti vs Radeon R9 270X

Intro

Compare all that to the Radeon R9 270X, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 memory works at a frequency of 1400 MHz on this particular card. It features 1280 SPUs along with 80 Texture Address Units and 32 ROPs.

Radeon R9 270X		180 Watts
GeForce RTX 3080 Ti		350 Watts
	Difference: 170 Watts (94%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3080 Ti should be 421% quicker than the Radeon R9 270X in general, because of its greater bandwidth. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
Radeon R9 270X		179200 MB/sec
	Difference: 755097 (421%)

Texel Rate

The GeForce RTX 3080 Ti is a lot (more or less 446%) better at AF than the Radeon R9 270X. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
Radeon R9 270X		80000 Mtexels/sec
	Difference: 356800 (446%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 3080 Ti is the winner, and very much so. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
Radeon R9 270X		32000 Mpixels/sec
	Difference: 120880 (378%)

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 information (in units of MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 can be applied in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics 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 the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
