GeForce GTX 580 vs Radeon RX 5500 XT

Intro

Compare that to the Radeon RX 5500 XT, which makes use of a 7 nm design. AMD has set the core frequency at 1717 MHz. The GDDR6 RAM runs at a frequency of 1750 MHz on this card. It features 1408 SPUs along with 88 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500 XT		130 Watts
GeForce GTX 580		244 Watts
	Difference: 114 Watts (88%)

Memory Bandwidth

In theory, the Radeon RX 5500 XT is 19% faster than the GeForce GTX 580 overall, because of its higher bandwidth. (explain)

Radeon RX 5500 XT		229376 MB/sec
GeForce GTX 580		192384 MB/sec
	Difference: 36992 (19%)

Texel Rate

The Radeon RX 5500 XT should be much (approximately 206%) better at texture filtering than the GeForce GTX 580. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
GeForce GTX 580		49408 Mtexels/sec
	Difference: 101688 (206%)

Pixel Rate

The Radeon RX 5500 XT should be much (more or less 48%) more effective at full screen anti-aliasing than the GeForce GTX 580, and also capable of handling higher screen resolutions better. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
GeForce GTX 580		37056 Mpixels/sec
	Difference: 17888 (48%)

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 data (measured in MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
