GeForce GTX 580 vs Radeon RX 5500 XT

Intro

Compare those specs 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 speed of 1750 MHz on this specific model. 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

Performance-wise, the Radeon RX 5500 XT should in theory be just a bit superior to the GeForce GTX 580 overall. (explain)

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

Texel Rate

The Radeon RX 5500 XT will be much (more or less 206%) faster with regards to 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 quite a bit (about 48%) more effective at FSAA than the GeForce GTX 580, and also should be capable of handling higher screen resolutions without slowing down too much. (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 maximum amount of information (in units of MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number 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 output 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 reach the max fill rate.
