GeForce 920M vs Radeon RX 5700

Intro

The GeForce 920M comes with a core clock speed of 954 MHz and a DDR3 memory frequency of 900 MHz. It also uses a 64-bit memory bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 32 Texture Address Units, and 8 Raster Operation Units.

Compare those specifications to the Radeon RX 5700, which has a clock speed of 1465 MHz and a GDDR6 memory frequency of 1750 MHz. It also makes use of a 256-bit memory bus, and makes use of a 7 nm design. It features 2304 SPUs, 144 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 5700 should be a lot faster than the GeForce 920M in general. (explain)

Radeon RX 5700 458752 MB/sec
GeForce 920M 14400 MB/sec
Difference: 444352 (3086%)

Texel Rate

The Radeon RX 5700 should be quite a bit (about 591%) more effective at AF than the GeForce 920M. (explain)

Radeon RX 5700 210960 Mtexels/sec
GeForce 920M 30528 Mtexels/sec
Difference: 180432 (591%)

Pixel Rate

The Radeon RX 5700 is a lot (approximately 1129%) faster with regards to AA than the GeForce 920M, and will be capable of handling higher resolutions better. (explain)

Radeon RX 5700 93760 Mpixels/sec
GeForce 920M 7632 Mpixels/sec
Difference: 86128 (1129%)

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 data (measured in MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling 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 the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
