GeForce RTX 2080 vs Radeon RX 5700

Intro

The GeForce RTX 2080 comes with a clock speed of 1515 MHz and a GDDR6 memory frequency of 14 MHz. It also uses a 256-bit bus, and uses a 12 nm design. It is comprised of 2944 SPUs, 184 Texture Address Units, and 64 ROPs.

Compare those specifications to the Radeon RX 5700, which comes with clock speeds of 1465 MHz on the GPU, and 14000 MHz on the 8096 MB of GDDR6 memory. It features 2304 SPUs as well as 144 TAUs and 64 Rasterization Operator Units.

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 the exact same memory bandwidth, so theoretically they should have identical performance. (explain)

Texel Rate

The GeForce RTX 2080 will be quite a bit (approximately 32%) more effective at AF 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 is just a bit (approximately 3%) more effective at AA than the Radeon RX 5700, and capable of handling higher resolutions without slowing down too much. (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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
