GeForce GTX 580 3GB vs Radeon RX 5500

Intro

Compare that to the Radeon RX 5500, which features a clock frequency of 1670 MHz and a GDDR6 memory frequency of 1750 MHz. It also makes use of a 128-bit bus, and uses a 7 nm design. It is made up of 1408 SPUs, 88 TAUs, and 32 Raster Operation Units.

Memory Bandwidth

Performance-wise, the Radeon RX 5500 should in theory be just a bit superior to the GeForce GTX 580 3GB in general. (explain)

Radeon RX 5500		229376 MB/sec
GeForce GTX 580 3GB		192384 MB/sec
	Difference: 36992 (19%)

Texel Rate

The Radeon RX 5500 will be much (more or less 197%) more effective at AF than the GeForce GTX 580 3GB. (explain)

Radeon RX 5500		146960 Mtexels/sec
GeForce GTX 580 3GB		49408 Mtexels/sec
	Difference: 97552 (197%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 5500 is the winner, by a large margin. (explain)

Radeon RX 5500		53440 Mpixels/sec
GeForce GTX 580 3GB		37056 Mpixels/sec
	Difference: 16384 (44%)

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 (counted in megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
