Radeon HD 7750 vs Radeon RX 5500 XT

Intro

Compare those specs to the Radeon RX 5500 XT, which comes with core speeds of 1717 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 memory. It features 1408 SPUs as well as 88 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Performance-wise, the Radeon RX 5500 XT should in theory be much better than the Radeon HD 7750 in general. (explain)

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

Texel Rate

The Radeon RX 5500 XT should be quite a bit (more or less 490%) faster with regards to anisotropic 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 lots of anti-aliasing is important to you, then the Radeon RX 5500 XT is a better choice, and very much so. (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 maximum amount of data (in units of MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
