Radeon RX 5700 vs Radeon RX 590

Intro

Compare that to the Radeon RX 590, which comes with GPU clock speed of 1469 MHz, and 8192 MB of GDDR5 memory running at 2000 MHz through a 256-bit bus. It also is comprised of 2304 SPUs, 144 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 590		175 Watts
Radeon RX 5700		180 Watts
	Difference: 5 Watts (3%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5700 is 75% quicker than the Radeon RX 590 overall, due to its higher bandwidth. (explain)

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

Texel Rate

The Radeon RX 590 will be a little bit (about 0%) more effective at anisotropic filtering than the Radeon RX 5700. (explain)

Radeon RX 590		211536 Mtexels/sec
Radeon RX 5700		210960 Mtexels/sec
	Difference: 576 (0%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 5700 is the winner, and very much so. (explain)

Radeon RX 5700		93760 Mpixels/sec
Radeon RX 590		47008 Mpixels/sec
	Difference: 46752 (99%)

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 maximum amount of information (counted in MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 per second. This is calculated by multiplying the total texture units of the card 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
