Radeon RX 6650 XT vs Radeon RX 6700 XT

Intro

Compare that to the Radeon RX 6700 XT, which has a GPU core clock speed of 2321 MHz, and (Unknown) MB of GDDR6 memory running at 2000 MHz through a 192-bit bus. It also is comprised of 2560 Stream Processors, 160 Texture Address Units, and 64 ROPs.

Radeon RX 6650 XT		287072 MB/sec
	Difference: 106144 (37%)

Texel Rate

The Radeon RX 6700 XT should be quite a bit (approximately 41%) more effective at AF than the Radeon RX 6650 XT. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
Radeon RX 6650 XT		263040 Mtexels/sec
	Difference: 108320 (41%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6700 XT is the winner, though only just barely. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
Radeon RX 6650 XT		131520 Mpixels/sec
	Difference: 17024 (13%)

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 max amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the 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 chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of 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 output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
