Radeon HD 3650 512MB vs Radeon RX 5700 XT

Intro

Compare all that to the Radeon RX 5700 XT, which comes with GPU core speed of 1605 MHz, and 8096 MB of GDDR6 memory running at 1750 MHz through a 256-bit bus. It also is comprised of 2560 SPUs, 160 TAUs, and 64 ROPs.

Radeon RX 5700 XT		256800 Mtexels/sec
Radeon HD 3650 512MB		5800 Mtexels/sec
	Difference: 251000 (4328%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 5700 XT is superior to the Radeon HD 3650 512MB, and very much so. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
Radeon HD 3650 512MB		2900 Mpixels/sec
	Difference: 99820 (3442%)

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 max amount of data (counted in megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
