GeForce RTX 3090 vs Radeon RX 5700 XT

Intro

Compare all of that to the Radeon RX 5700 XT, which makes use of a 7 nm design. AMD has set the core frequency at 1605 MHz. The GDDR6 RAM works at a speed of 1750 MHz on this specific card. It features 2560 SPUs along with 160 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700 XT		225 Watts
GeForce RTX 3090		350 Watts
	Difference: 125 Watts (56%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3090 will be 109% faster than the Radeon RX 5700 XT in general, due to its greater bandwidth. (explain)

GeForce RTX 3090		958668 MB/sec
Radeon RX 5700 XT		458752 MB/sec
	Difference: 499916 (109%)

Texel Rate

The GeForce RTX 3090 is a lot (about 78%) faster with regards to AF than the Radeon RX 5700 XT. (explain)

GeForce RTX 3090		457560 Mtexels/sec
Radeon RX 5700 XT		256800 Mtexels/sec
	Difference: 200760 (78%)

Pixel Rate

The GeForce RTX 3090 is quite a bit (approximately 52%) more effective at full screen anti-aliasing than the Radeon RX 5700 XT, and also will be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce RTX 3090		156240 Mpixels/sec
Radeon RX 5700 XT		102720 Mpixels/sec
	Difference: 53520 (52%)

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 largest amount of data (measured in MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, 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 calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the 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 most pixels that the graphics chip can possibly record to the local memory per 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 - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
