GeForce RTX 2080 vs Radeon RX 5700

Intro

Compare all of that to the Radeon RX 5700, which makes use of a 7 nm design. AMD has set the core frequency at 1465 MHz. The GDDR6 RAM is set to run at a speed of 1750 MHz on this specific card. It features 2304 SPUs along with 144 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700		180 Watts
GeForce RTX 2080		215 Watts
	Difference: 35 Watts (19%)

Memory Bandwidth

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

Texel Rate

The GeForce RTX 2080 will be quite a bit (more or less 32%) better at anisotropic filtering than the Radeon RX 5700. (explain)

GeForce RTX 2080		278760 Mtexels/sec
Radeon RX 5700		210960 Mtexels/sec
	Difference: 67800 (32%)

Pixel Rate

The GeForce RTX 2080 will be a little bit (about 3%) more effective at FSAA than the Radeon RX 5700, and capable of handling higher resolutions while still performing well. (explain)

GeForce RTX 2080		96960 Mpixels/sec
Radeon RX 5700		93760 Mpixels/sec
	Difference: 3200 (3%)

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 maximum amount of information (counted in megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 amount 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 speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock 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 output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
