Radeon RX 5700 XT 50th Anniversary Edition vs Radeon RX 580

Intro

Compare all of that to the Radeon RX 580, which features GPU clock speed of 1257 MHz, and 8192 MB of GDDR5 RAM running at 2000 MHz through a 256-bit bus. It also is comprised of 2304 SPUs, 144 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 580		185 Watts
Radeon RX 5700 XT 50th Anniversary Edition		235 Watts
	Difference: 50 Watts (27%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5700 XT 50th Anniversary Edition should perform a lot faster than the Radeon RX 580 in general. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		458752 MB/sec
Radeon RX 580		262144 MB/sec
	Difference: 196608 (75%)

Texel Rate

The Radeon RX 5700 XT 50th Anniversary Edition should be quite a bit (more or less 49%) faster with regards to AF than the Radeon RX 580. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		268800 Mtexels/sec
Radeon RX 580		181008 Mtexels/sec
	Difference: 87792 (49%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 5700 XT 50th Anniversary Edition is superior to the Radeon RX 580, by a large margin. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		107520 Mpixels/sec
Radeon RX 580		40224 Mpixels/sec
	Difference: 67296 (167%)

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 (counted in megabytes per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 can be processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
