Radeon HD 7950 vs Radeon RX 5600

Intro

Compare those specs to the Radeon RX 5600, which features a clock speed of 1375 MHz and a GDDR6 memory speed of 1500 MHz. It also uses a 192-bit memory bus, and makes use of a 7 nm design. It is comprised of 2048 SPUs, 128 Texture Address Units, and 64 ROPs.

Radeon HD 7950		89600 Mtexels/sec
	Difference: 86400 (96%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 5600 is a better choice, and very much so. (explain)

Radeon RX 5600		88000 Mpixels/sec
Radeon HD 7950		25600 Mpixels/sec
	Difference: 62400 (244%)

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 data (in units of MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
