Geforce GTX 780 vs Radeon RX 5500

Intro

Compare all that to the Radeon RX 5500, which comes with core clock speeds of 1670 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR6 memory. It features 1408 SPUs along with 88 TAUs and 32 ROPs.

Radeon RX 5500		146960 Mtexels/sec
	Difference: 18736 (13%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 5500 is superior to the Geforce GTX 780, by a large margin. (explain)

Radeon RX 5500		53440 Mpixels/sec
Geforce GTX 780		41424 Mpixels/sec
	Difference: 12016 (29%)

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 largest amount of data (counted in megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better 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 amount of texture map elements (texels) that are applied in one second. This number is worked out 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
