GeForce GTX 980 Ti vs Radeon RX 5500 XT

Intro

Compare those specifications to the Radeon RX 5500 XT, which uses a 7 nm design. AMD has set the core frequency at 1717 MHz. The GDDR6 memory is set to run at a speed of 1750 MHz on this particular model. It features 1408 SPUs as well as 88 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500 XT		130 Watts
GeForce GTX 980 Ti		250 Watts
	Difference: 120 Watts (92%)

Memory Bandwidth

The GeForce GTX 980 Ti, in theory, should be quite a bit faster than the Radeon RX 5500 XT overall. (explain)

GeForce GTX 980 Ti		336000 MB/sec
Radeon RX 5500 XT		229376 MB/sec
	Difference: 106624 (46%)

Texel Rate

The GeForce GTX 980 Ti should be just a bit (approximately 16%) more effective at anisotropic filtering than the Radeon RX 5500 XT. (explain)

GeForce GTX 980 Ti		176000 Mtexels/sec
Radeon RX 5500 XT		151096 Mtexels/sec
	Difference: 24904 (16%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 980 Ti is the winner, by a large margin. (explain)

GeForce GTX 980 Ti		96000 Mpixels/sec
Radeon RX 5500 XT		54944 Mpixels/sec
	Difference: 41056 (75%)

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 max amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out 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 video 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 maximum number of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
