GeForce GTX 970 vs Radeon RX 5500 XT

Intro

Compare those specs to the Radeon RX 5500 XT, which has core clock speeds of 1717 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 RAM. 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 970		145 Watts
	Difference: 15 Watts (12%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5500 XT will be 2% quicker than the GeForce GTX 970 overall, because of its greater data rate. (explain)

Radeon RX 5500 XT		229376 MB/sec
GeForce GTX 970		224000 MB/sec
	Difference: 5376 (2%)

Texel Rate

The Radeon RX 5500 XT will be a lot (about 38%) better at AF than the GeForce GTX 970. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
GeForce GTX 970		109200 Mtexels/sec
	Difference: 41896 (38%)

Pixel Rate

The GeForce GTX 970 should be a lot (more or less 22%) better at AA than the Radeon RX 5500 XT, and should be able to handle higher resolutions better. (explain)

GeForce GTX 970		67200 Mpixels/sec
Radeon RX 5500 XT		54944 Mpixels/sec
	Difference: 12256 (22%)

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 (in units of MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 can be applied per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, 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 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 colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
