GeForce GTX 580 3GB vs Radeon RX 5500

Intro

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

	Difference: 97552 (197%)

Pixel Rate

The Radeon RX 5500 should be quite a bit (approximately 44%) more effective at anti-aliasing than the GeForce GTX 580 3GB, and also able to handle higher resolutions better. (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 max amount of data (in units of megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
