Radeon R9 390X 8G vs Radeon RX 5600 XT

Intro

Compare that to the Radeon RX 5600 XT, which makes use of a 7 nm design. AMD has set the core speed at 1375 MHz. The GDDR6 memory is set to run at a speed of 1500 MHz on this particular card. It features 2304 SPUs as well as 144 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600 XT		160 Watts
Radeon R9 390X 8G		275 Watts
	Difference: 115 Watts (72%)

Memory Bandwidth

In theory, the Radeon R9 390X 8G should be 12% quicker than the Radeon RX 5600 XT in general, because of its higher bandwidth. (explain)

Radeon R9 390X 8G		384000 MB/sec
Radeon RX 5600 XT		344064 MB/sec
	Difference: 39936 (12%)

Texel Rate

The Radeon RX 5600 XT is a bit (about 7%) more effective at anisotropic filtering than the Radeon R9 390X 8G. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
Radeon R9 390X 8G		184800 Mtexels/sec
	Difference: 13200 (7%)

Pixel Rate

The Radeon RX 5600 XT should be much (approximately 31%) more effective at FSAA than the Radeon R9 390X 8G, and capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
Radeon R9 390X 8G		67200 Mpixels/sec
	Difference: 20800 (31%)

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 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 card's interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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