Radeon HD 3650 vs Radeon RX 5700 XT

Intro

Compare that to the Radeon RX 5700 XT, which makes use of a 7 nm design. AMD has clocked the core speed at 1605 MHz. The GDDR6 RAM runs at a frequency of 1750 MHz on this card. It features 2560 SPUs along with 160 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 3650		78 Watts
Radeon RX 5700 XT		225 Watts
	Difference: 147 Watts (188%)

Memory Bandwidth

In theory, the Radeon RX 5700 XT will be 1692% faster than the Radeon HD 3650 in general, due to its higher data rate. (explain)

Radeon RX 5700 XT		458752 MB/sec
Radeon HD 3650		25600 MB/sec
	Difference: 433152 (1692%)

Texel Rate

The Radeon RX 5700 XT should be quite a bit (more or less 4328%) better at texture filtering than the Radeon HD 3650. (explain)

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

Pixel Rate

The Radeon RX 5700 XT is a lot (approximately 3442%) more effective at AA than the Radeon HD 3650, and should be able to handle higher screen resolutions better. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
Radeon HD 3650		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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
