GeForce 920M vs Radeon RX 6650 XT

Intro

The GeForce 920M uses a 28 nm design. nVidia has set the core frequency at 954 MHz. The DDR3 RAM runs at a speed of 900 MHz on this specific model. It features 384 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.

Compare those specs to the Radeon RX 6650 XT, which uses a 7 nm design. AMD has set the core frequency at 2055 MHz. The GDDR6 RAM runs at a frequency of 2190 MHz on this model. It features 2048 SPUs along with 128 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon RX 6650 XT should perform much faster than the GeForce 920M in general. (explain)

Radeon RX 6650 XT 287072 MB/sec
GeForce 920M 14400 MB/sec
Difference: 272672 (1894%)

Texel Rate

The Radeon RX 6650 XT will be quite a bit (approximately 762%) faster with regards to texture filtering than the GeForce 920M. (explain)

Radeon RX 6650 XT 263040 Mtexels/sec
GeForce 920M 30528 Mtexels/sec
Difference: 232512 (762%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6650 XT is superior to the GeForce 920M, by far. (explain)

Radeon RX 6650 XT 131520 Mpixels/sec
GeForce 920M 7632 Mpixels/sec
Difference: 123888 (1623%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 are applied per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
