Radeon RX 5700 XT vs Radeon RX 590

Intro

Compare all of that to the Radeon RX 590, which uses a 12 nm design. AMD has set the core speed at 1469 MHz. The GDDR5 memory runs at a speed of 2000 MHz on this specific model. It features 2304 SPUs along with 144 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 590		175 Watts
Radeon RX 5700 XT		225 Watts
	Difference: 50 Watts (29%)

Memory Bandwidth

In theory, the Radeon RX 5700 XT is 75% faster than the Radeon RX 590 in general, because of its higher bandwidth. (explain)

Radeon RX 5700 XT		458752 MB/sec
Radeon RX 590		262144 MB/sec
	Difference: 196608 (75%)

Texel Rate

The Radeon RX 5700 XT is quite a bit (approximately 21%) faster with regards to anisotropic filtering than the Radeon RX 590. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
Radeon RX 590		211536 Mtexels/sec
	Difference: 45264 (21%)

Pixel Rate

The Radeon RX 5700 XT should be a lot (more or less 119%) faster with regards to AA than the Radeon RX 590, and will be capable of handling higher resolutions more effectively. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
Radeon RX 590		47008 Mpixels/sec
	Difference: 55712 (119%)

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 information (counted in megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied 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 amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
