GeForce RTX 3080 vs Radeon RX 5700

Intro

Compare that to the Radeon RX 5700, which comes with a clock speed of 1465 MHz and a GDDR6 memory speed of 1750 MHz. It also features a 256-bit memory bus, and makes use of a 7 nm design. It is made up of 2304 SPUs, 144 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700		180 Watts
GeForce RTX 3080		320 Watts
	Difference: 140 Watts (78%)

Memory Bandwidth

Theoretically, the GeForce RTX 3080 should perform quite a bit faster than the Radeon RX 5700 in general. (explain)

GeForce RTX 3080		778547 MB/sec
Radeon RX 5700		458752 MB/sec
	Difference: 319795 (70%)

Texel Rate

The GeForce RTX 3080 is a lot (more or less 86%) more effective at texture filtering than the Radeon RX 5700. (explain)

GeForce RTX 3080		391680 Mtexels/sec
Radeon RX 5700		210960 Mtexels/sec
	Difference: 180720 (86%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 3080 is a better choice, by far. (explain)

GeForce RTX 3080		138240 Mpixels/sec
Radeon RX 5700		93760 Mpixels/sec
	Difference: 44480 (47%)

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 largest amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
