Radeon HD 6790 vs Radeon RX 5600

Intro

Compare all that to the Radeon RX 5600, which uses a 7 nm design. AMD has clocked the core frequency at 1375 MHz. The GDDR6 RAM works at a frequency of 1500 MHz on this card. It features 2048 SPUs along with 128 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Radeon RX 5600 is 119% quicker than the Radeon HD 6790 overall, due to its higher data rate. (explain)

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

Texel Rate

The Radeon RX 5600 is quite a bit (approximately 424%) faster with regards to AF than the Radeon HD 6790. (explain)

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

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 5600 is a better choice, by far. (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 maximum amount of information (measured in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
