GeForce RTX 3080 Ti vs Radeon R9 M385X

Intro

Compare all that to the Radeon R9 M385X, which uses a 28 nm design. AMD has set the core speed at 1100 MHz. The GDDR5 memory is set to run at a frequency of 1500 MHz on this specific model. It features 896 SPUs as well as 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3080 Ti should be a lot faster than the Radeon R9 M385X in general. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 838297 (873%)

Texel Rate

The GeForce RTX 3080 Ti should be much (about 609%) more effective at AF than the Radeon R9 M385X. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
Radeon R9 M385X		61600 Mtexels/sec
	Difference: 375200 (609%)

Pixel Rate

The GeForce RTX 3080 Ti should be quite a bit (more or less 769%) more effective at full screen anti-aliasing than the Radeon R9 M385X, and also will be capable of handling higher screen resolutions better. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 135280 (769%)

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 (counted in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock 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 is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
