AMD Ryzen 5 3550H

The AMD Ryzen 5 3550H is a mobile SoC that was announced in January 2019. It combines four Zen+ cores (8 threads) clocked at 2.1 GHz to 3.7 GHz with a Radeon RX Vega 8 graphics adapter with 8 CUs (512 Shaders) clocked at up to 1,200 MHz. Compared to the similar Ryzen 5 3500U, the 3550H offers a 20 Watt higher TDP and therefore a better performance under long periods of load. The integrated dual-channel memory controller supports up to DDR4-2400 memory. As the features of the Picasso APUs are the same compared to the Raven Ridge predecessors, we point to our Raven Ridge launch article.

The Picasso SoCs use the Zen+ microarchitecture with slight improvements that should lead to a 3% IPS (performance per clock) improvements. Furthermore, the 12 nm process allows higher clock rates at similar power consumptions.

Performance

The average 3550H in our database proves itself as a solid mid-range CPU, its multi-thread benchmark scores hovering around those of Intel Core i7-10710U and Core i5-8257U. Which is a little slow for an H-class processor but still more than enough for the vast majority of apps and games, provided one is happy to wait a little longer than usual for that 4K video encoding job to get completed.

Power consumption

This Ryzen 5 has a default TDP (also known as the long-term power limit) of 35 W. Laptop manufacturers are free to change this value to anything between 12 W and 35 W, with clock speeds and performance changing accordingly as a result. Either way, that's a little too high to allow for passively cooled designs.

Last but not the least, the AMD APU is built with a fairly old, as of late 2022, 12 nm process for average energy efficiency.
