GeForce RTX 2070 vs Radeon RX 5700

Intro

Compare those specifications to the Radeon RX 5700, which features a GPU core clock speed of 1465 MHz, and 8096 MB of GDDR6 memory running at 1750 MHz through a 256-bit bus. It also features 2304 Stream Processors, 144 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2070		175 Watts
Radeon RX 5700		180 Watts
	Difference: 5 Watts (3%)

Memory Bandwidth

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

Texel Rate

The Radeon RX 5700 will be a small bit (approximately 4%) faster with regards to AF than the GeForce RTX 2070. (explain)

Radeon RX 5700		210960 Mtexels/sec
GeForce RTX 2070		203040 Mtexels/sec
	Difference: 7920 (4%)

Pixel Rate

The Radeon RX 5700 should be a bit (more or less 4%) more effective at AA than the GeForce RTX 2070, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 5700		93760 Mpixels/sec
GeForce RTX 2070		90240 Mpixels/sec
	Difference: 3520 (4%)

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 moved across the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 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, High Dynamic Range and high resolutions.

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

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