GeForce RTX 3080 Ti vs Radeon RX 470 4GB

Intro

Compare all that to the Radeon RX 470 4GB, which uses a 14 nm design. AMD has set the core frequency at 926 MHz. The GDDR5 RAM is set to run at a frequency of 1650 MHz on this particular model. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 470 4GB		120 Watts
GeForce RTX 3080 Ti		350 Watts
	Difference: 230 Watts (192%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3080 Ti should be 342% quicker than the Radeon RX 470 4GB in general, because of its greater data rate. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
Radeon RX 470 4GB		211200 MB/sec
	Difference: 723097 (342%)

Texel Rate

The GeForce RTX 3080 Ti will be much (more or less 269%) faster with regards to texture filtering than the Radeon RX 470 4GB. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
Radeon RX 470 4GB		118528 Mtexels/sec
	Difference: 318272 (269%)

Pixel Rate

The GeForce RTX 3080 Ti should be a lot (approximately 416%) more effective at AA than the Radeon RX 470 4GB, and also will be able to handle higher resolutions without losing too much performance. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
Radeon RX 470 4GB		29632 Mpixels/sec
	Difference: 123248 (416%)

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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's 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 number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
