GeForce RTX 3080 Ti vs Radeon R9 270

Intro

Compare those specifications to the Radeon R9 270, which makes use of a 28 nm design. AMD has clocked the core speed at 900 MHz. The GDDR5 memory runs at a speed of 1400 MHz on this specific card. It features 1280 SPUs as well as 80 TAUs and 32 Rasterization Operator Units.

Radeon R9 270		72000 Mtexels/sec
	Difference: 364800 (507%)

Pixel Rate

The GeForce RTX 3080 Ti should be quite a bit (about 431%) more effective at full screen anti-aliasing than the Radeon R9 270, and also will be capable of handling higher screen resolutions more effectively. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
Radeon R9 270		28800 Mpixels/sec
	Difference: 124080 (431%)

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 megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at 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 video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
