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

Intro

Compare those specs to the Radeon RX 580, which makes use of a 14 nm design. AMD has clocked the core speed at 1257 MHz. The GDDR5 memory works at a frequency of 2000 MHz on this specific card. It features 2304 SPUs along with 144 TAUs 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

As far as performance goes, the Radeon RX 5700 XT 50th Anniversary Edition should in theory be much superior to the Radeon RX 580 overall. (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 will be much (approximately 49%) more effective at anisotropic filtering 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 running with lots of anti-aliasing is important to you, then the Radeon RX 5700 XT 50th Anniversary Edition is a better choice, and very much so. (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: Memory bandwidth is the max amount of information (counted in MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock 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 applied per second.

Pixel Rate: Pixel rate is the most pixels that 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 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 also depends on many 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.
