Radeon HD 7750 vs Radeon RX 6800

Intro

Compare those specifications to the Radeon RX 6800, which uses a 7 nm design. AMD has set the core frequency at 1700 MHz. The GDDR6 memory runs at a speed of 2000 MHz on this card. It features 3840 SPUs along with 240 Texture Address Units and 96 Rasterization Operator Units.

Radeon HD 7750		55 Watts
Radeon RX 6800		250 Watts
	Difference: 195 Watts (355%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6800 will be 628% faster than the Radeon HD 7750 in general, due to its higher bandwidth. (explain)

Radeon RX 6800		524288 MB/sec
Radeon HD 7750		72000 MB/sec
	Difference: 452288 (628%)

Texel Rate

The Radeon RX 6800 should be a lot (about 1494%) more effective at texture filtering than the Radeon HD 7750. (explain)

Radeon RX 6800		408000 Mtexels/sec
Radeon HD 7750		25600 Mtexels/sec
	Difference: 382400 (1494%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 6800 is the winner, by far. (explain)

Radeon RX 6800		163200 Mpixels/sec
Radeon HD 7750		12800 Mpixels/sec
	Difference: 150400 (1175%)

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 information (counted in megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum 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 this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 max fill rate.
