Radeon RX 6650 XT vs Radeon VII

Intro

Compare those specs to the Radeon VII, which comes with a GPU core clock speed of 1400 MHz, and 16384 MB of HBM2 RAM running at 1000 MHz through a 4096-bit bus. It also features 3840 SPUs, 240 TAUs, and 64 Raster Operation Units.

Radeon RX 6650 XT		287072 MB/sec
	Difference: 761504 (265%)

Texel Rate

The Radeon VII will be much (about 28%) more effective at texture filtering than the Radeon RX 6650 XT. (explain)

Radeon VII		336000 Mtexels/sec
Radeon RX 6650 XT		263040 Mtexels/sec
	Difference: 72960 (28%)

Pixel Rate

The Radeon RX 6650 XT will be a lot (about 47%) faster with regards to anti-aliasing than the Radeon VII, and should be able to handle higher screen resolutions more effectively. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
Radeon VII		89600 Mpixels/sec
	Difference: 41920 (47%)

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 largest amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated 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 rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
