Radeon RX 550 vs Radeon RX 6650 XT

Intro

Compare all of that to the Radeon RX 6650 XT, which uses a 7 nm design. AMD has set the core frequency at 2055 MHz. The GDDR6 memory is set to run at a speed of 2190 MHz on this particular card. It features 2048 SPUs as well as 128 Texture Address Units and 64 ROPs.

Radeon RX 550		50 Watts
Radeon RX 6650 XT		176 Watts
	Difference: 126 Watts (252%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6650 XT should perform quite a bit faster than the Radeon RX 550 in general. (explain)

Radeon RX 6650 XT		287072 MB/sec
Radeon RX 550		114688 MB/sec
	Difference: 172384 (150%)

Texel Rate

The Radeon RX 6650 XT should be much (about 647%) better at anisotropic filtering than the Radeon RX 550. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 227840 (647%)

Pixel Rate

The Radeon RX 6650 XT will be much (more or less 647%) more effective at AA than the Radeon RX 550, and also will be able to handle higher resolutions better. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 113920 (647%)

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 megabytes per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can 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 colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
