GeForce GTX 1070 Ti vs Radeon RX 5500 XT

Intro

Compare all that to the Radeon RX 5500 XT, which features a clock frequency of 1717 MHz and a GDDR6 memory speed of 1750 MHz. It also uses a 128-bit bus, and uses a 7 nm design. It is comprised of 1408 SPUs, 88 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500 XT		130 Watts
GeForce GTX 1070 Ti		180 Watts
	Difference: 50 Watts (38%)

Memory Bandwidth

In theory, the GeForce GTX 1070 Ti should be 14% faster than the Radeon RX 5500 XT in general, because of its greater data rate. (explain)

GeForce GTX 1070 Ti		262144 MB/sec
Radeon RX 5500 XT		229376 MB/sec
	Difference: 32768 (14%)

Texel Rate

The GeForce GTX 1070 Ti should be quite a bit (approximately 62%) better at texture filtering than the Radeon RX 5500 XT. (explain)

GeForce GTX 1070 Ti		244264 Mtexels/sec
Radeon RX 5500 XT		151096 Mtexels/sec
	Difference: 93168 (62%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 1070 Ti is a better choice, and very much so. (explain)

GeForce GTX 1070 Ti		102848 Mpixels/sec
Radeon RX 5500 XT		54944 Mpixels/sec
	Difference: 47904 (87%)

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 (in units of megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The better 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 amount of pixels the video card could possibly write to its 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 - aka 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
