Radeon RX 6650 XT vs Radeon VII

Intro

Compare that 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 is comprised of 3840 Stream Processors, 240 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6650 XT		176 Watts
Radeon VII		295 Watts
	Difference: 119 Watts (68%)

Memory Bandwidth

Theoretically, the Radeon VII should perform a lot faster than the Radeon RX 6650 XT overall. (explain)

Radeon VII		1048576 MB/sec
Radeon RX 6650 XT		287072 MB/sec
	Difference: 761504 (265%)

Texel Rate

The Radeon VII should be quite a bit (approximately 28%) faster with regards to anisotropic 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

If running with lots of anti-aliasing is important to you, then the Radeon RX 6650 XT is superior to the Radeon VII, and very much so. (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: Bandwidth is the maximum amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum 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 better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
