GeForce RTX 2070 vs Radeon RX 5700 XT

Intro

Compare that to the Radeon RX 5700 XT, which has a clock speed of 1605 MHz and a GDDR6 memory frequency of 1750 MHz. It also uses a 256-bit memory bus, and makes use of a 7 nm design. It features 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2070		175 Watts
Radeon RX 5700 XT		225 Watts
	Difference: 50 Watts (29%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The Radeon RX 5700 XT will be a lot (approximately 26%) better at AF than the GeForce RTX 2070. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
GeForce RTX 2070		203040 Mtexels/sec
	Difference: 53760 (26%)

Pixel Rate

The Radeon RX 5700 XT should be a little bit (more or less 14%) more effective at full screen anti-aliasing than the GeForce RTX 2070, and capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
GeForce RTX 2070		90240 Mpixels/sec
	Difference: 12480 (14%)

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 (measured in MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write 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 card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
