GeForce GTX 980 vs Radeon RX 5600 XT

Intro

Compare those specifications to the Radeon RX 5600 XT, which features GPU clock speed of 1375 MHz, and 6144 MB of GDDR6 RAM set to run at 1500 MHz through a 192-bit bus. It also is comprised of 2304 Stream Processors, 144 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600 XT		160 Watts
GeForce GTX 980		165 Watts
	Difference: 5 Watts (3%)

Memory Bandwidth

The Radeon RX 5600 XT should in theory be a lot faster than the GeForce GTX 980 in general. (explain)

Radeon RX 5600 XT		344064 MB/sec
GeForce GTX 980		224000 MB/sec
	Difference: 120064 (54%)

Texel Rate

The Radeon RX 5600 XT will be quite a bit (more or less 37%) better at AF than the GeForce GTX 980. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
GeForce GTX 980		144128 Mtexels/sec
	Difference: 53872 (37%)

Pixel Rate

The Radeon RX 5600 XT is quite a bit (more or less 22%) more effective at anti-aliasing than the GeForce GTX 980, and should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
GeForce GTX 980		72064 Mpixels/sec
	Difference: 15936 (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 largest amount of data (in units of MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the 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 figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
