GeForce GTX 580 vs Radeon RX 5500

Intro

Compare all that to the Radeon RX 5500, which features a GPU core clock speed of 1670 MHz, and 4096 MB of GDDR6 memory running at 1750 MHz through a 128-bit bus. It also is comprised of 1408 SPUs, 88 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500		150 Watts
GeForce GTX 580		244 Watts
	Difference: 94 Watts (63%)

Memory Bandwidth

In theory, the Radeon RX 5500 should be a little bit faster than the GeForce GTX 580 overall. (explain)

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

Texel Rate

The Radeon RX 5500 should be quite a bit (more or less 197%) more effective at anisotropic filtering than the GeForce GTX 580. (explain)

Radeon RX 5500		146960 Mtexels/sec
GeForce GTX 580		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		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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
