Radeon HD 7750 vs Radeon RX 5500 XT

Intro

Compare that to the Radeon RX 5500 XT, which has a GPU core clock speed of 1717 MHz, and 8192 MB of GDDR6 memory set to run at 1750 MHz through a 128-bit bus. It also is comprised of 1408 Stream Processors, 88 Texture Address Units, and 32 ROPs.

Radeon HD 7750		72000 MB/sec
	Difference: 157376 (219%)

Texel Rate

The Radeon RX 5500 XT is quite a bit (more or less 490%) more effective at texture filtering than the Radeon HD 7750. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
Radeon HD 7750		25600 Mtexels/sec
	Difference: 125496 (490%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 5500 XT is a better choice, by a large margin. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
Radeon HD 7750		12800 Mpixels/sec
	Difference: 42144 (329%)

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 largest amount of data (counted in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
