Radeon HD 7750 vs Radeon RX 5500

Intro

Compare those specifications to the Radeon RX 5500, which makes use of a 7 nm design. AMD has clocked the core frequency at 1670 MHz. The GDDR6 RAM runs at a speed of 1750 MHz on this model. It features 1408 SPUs along with 88 TAUs and 32 Rasterization Operator Units.

Radeon HD 7750		55 Watts
Radeon RX 5500		150 Watts
	Difference: 95 Watts (173%)

Memory Bandwidth

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

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

Texel Rate

The Radeon RX 5500 will be much (approximately 474%) faster with regards to AF than the Radeon HD 7750. (explain)

Radeon RX 5500		146960 Mtexels/sec
Radeon HD 7750		25600 Mtexels/sec
	Difference: 121360 (474%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 5500 is superior to the Radeon HD 7750, and very much so. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon HD 7750		12800 Mpixels/sec
	Difference: 40640 (318%)

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 information (counted in megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
