Geforce GTX 770 vs Radeon RX 5500 XT

Intro

Compare all of that to the Radeon RX 5500 XT, which comes with core speeds of 1717 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 memory. It features 1408 SPUs as well as 88 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500 XT		130 Watts
Geforce GTX 770		230 Watts
	Difference: 100 Watts (77%)

Memory Bandwidth

In theory, the Radeon RX 5500 XT should be 2% quicker than the Geforce GTX 770 in general, because of its greater bandwidth. (explain)

Radeon RX 5500 XT		229376 MB/sec
Geforce GTX 770		224384 MB/sec
	Difference: 4992 (2%)

Texel Rate

The Radeon RX 5500 XT is just a bit (approximately 13%) better at anisotropic filtering than the Geforce GTX 770. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
Geforce GTX 770		133888 Mtexels/sec
	Difference: 17208 (13%)

Pixel Rate

The Radeon RX 5500 XT will be quite a bit (approximately 64%) faster with regards to full screen anti-aliasing than the Geforce GTX 770, and should be capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
Geforce GTX 770		33472 Mpixels/sec
	Difference: 21472 (64%)

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 data (measured in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 are applied per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
