Radeon RX 5600 XT vs Radeon RX 6650 XT

Intro

Compare all of that to the Radeon RX 6650 XT, which features a core clock speed of 2055 MHz and a GDDR6 memory frequency of 2190 MHz. It also features a 128-bit memory bus, and makes use of a 7 nm design. It is made up of 2048 SPUs, 128 Texture Address Units, and 64 ROPs.

The Radeon RX 6650 XT is a lot (approximately 33%) faster with regards to AF than the Radeon RX 5600 XT. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
Radeon RX 5600 XT		198000 Mtexels/sec
	Difference: 65040 (33%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6650 XT is superior to the Radeon RX 5600 XT, and very much so. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
Radeon RX 5600 XT		88000 Mpixels/sec
	Difference: 43520 (49%)

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 MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video 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 one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
