Geforce GTX 770 vs Radeon RX 5500 XT

Intro

Compare all that to the Radeon RX 5500 XT, which makes use of a 7 nm design. AMD has clocked the core frequency at 1717 MHz. The GDDR6 memory works at a speed of 1750 MHz on this specific model. It features 1408 SPUs as well as 88 TAUs and 32 Rasterization Operator Units.

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

Memory Bandwidth

Theoretically speaking, the Radeon RX 5500 XT should perform just a bit faster than the Geforce GTX 770 overall. (explain)

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

Texel Rate

The Radeon RX 5500 XT will be a bit (about 13%) faster with regards to texture 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%) better at anti-aliasing than the Geforce GTX 770, and should be able to handle higher resolutions while still performing well. (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 largest amount of data (in units of MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 reach the max fill rate.
