Radeon HD 7750 vs Radeon RX 5500

Intro

Compare all of that to the Radeon RX 5500, which uses a 7 nm design. AMD has set the core speed at 1670 MHz. The GDDR6 memory is set to run at a frequency of 1750 MHz on this particular card. It features 1408 SPUs along with 88 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

The Radeon RX 5500 should theoretically perform much 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 quite a bit (about 474%) more effective at anisotropic filtering than the Radeon HD 7750. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 5500 is a better choice, 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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that are applied 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 this number, the better the card will be at 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 video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
