Radeon HD 6790 vs Radeon RX 5600

Intro

Compare those specifications to the Radeon RX 5600, which features GPU core speed of 1375 MHz, and 6144 MB of GDDR6 memory set to run at 1500 MHz through a 192-bit bus. It also is comprised of 2048 SPUs, 128 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

As far as performance goes, the Radeon RX 5600 should theoretically be quite a bit superior to the Radeon HD 6790 overall. (explain)

Radeon RX 5600		294912 MB/sec
Radeon HD 6790		134400 MB/sec
	Difference: 160512 (119%)

Texel Rate

The Radeon RX 5600 should be a lot (about 424%) more effective at anisotropic filtering than the Radeon HD 6790. (explain)

Radeon RX 5600		176000 Mtexels/sec
Radeon HD 6790		33600 Mtexels/sec
	Difference: 142400 (424%)

Pixel Rate

The Radeon RX 5600 is a lot (about 555%) more effective at AA than the Radeon HD 6790, and able to handle higher resolutions without slowing down too much. (explain)

Radeon RX 5600		88000 Mpixels/sec
Radeon HD 6790		13440 Mpixels/sec
	Difference: 74560 (555%)

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 data (in units of megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. 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 is also dependant 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 maximum fill rate.
