Geforce GTX 770 vs Radeon RX 5500 XT

Intro

Compare that to the Radeon RX 5500 XT, which uses a 7 nm design. AMD has set the core speed at 1717 MHz. The GDDR6 memory works at a speed of 1750 MHz on this particular model. It features 1408 SPUs along with 88 TAUs 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, due to its higher data rate. (explain)

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

Texel Rate

The Radeon RX 5500 XT should be a bit (about 13%) faster with regards to AF than the Geforce GTX 770. (explain)

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

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 5500 XT is the winner, and very much so. (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: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory per 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 output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
