Radeon HD 7750 vs Radeon RX 5500 XT

Intro

Compare that to the Radeon RX 5500 XT, which uses a 7 nm design. AMD has clocked the core frequency at 1717 MHz. The GDDR6 RAM works at a frequency of 1750 MHz on this model. It features 1408 SPUs along with 88 Texture Address Units and 32 ROPs.

Radeon HD 7750		55 Watts
Radeon RX 5500 XT		130 Watts
	Difference: 75 Watts (136%)

Memory Bandwidth

Theoretically, the Radeon RX 5500 XT should perform quite a bit faster than the Radeon HD 7750 overall. (explain)

Radeon RX 5500 XT		229376 MB/sec
Radeon HD 7750		72000 MB/sec
	Difference: 157376 (219%)

Texel Rate

The Radeon RX 5500 XT is a lot (about 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

The Radeon RX 5500 XT will be quite a bit (more or less 329%) faster with regards to FSAA than the Radeon HD 7750, and also should be capable of handling higher resolutions more effectively. (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 max amount of data (measured in megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
