AMD Ryzen 5 6600H

The AMD Ryzen 5 6600H is a processor for big (gaming) laptops based of the Rembrandt generation. The R5 6600H integrates six of the eight cores based on the Zen 3+ microarchitecture. They are clocked at 3.3 (guaranteed base clock) to 4.5 GHz (Turbo) and support SMT / Hyperthreading (12 threads). The chip is manufactured on the modern 6 nm TSMC process. 

The new Zen 3+ is a refresh of the Zen 3 architecture and should not offer a lot of changes. The chip itself however, offers a lot of new features, like support for USB 4 (40 Gbps), PCI-E Gen 4, DDR5-4800MT/s or LPDDR5-6400MT/s, WiFi 6E, Bluetooth LE 5.2, DisplayPort 2, and AV1 decode.

In the 6000 series, AMD finally switched to the current RDNA 2 graphics architecture for the iGPU. The 6600H only offers the slower Radeon 660M with 6 of the 12 CUs enabled and 1.9 GHz max. clock speed.

Performance

The average 6600H in our database is in the same league as the R7 5825U, the R7 6800U and also the Core i5-1340P, as far as multi-thread benchmark scores are concerned. This is a very decent result, as of late 2022.

Your mileage may vary depending on how high the CPU power limits are, and how competent the cooling solution of your system is.

Power consumption

This Ryzen 5 series APU has a default TDP, also known as the long-term power limit, of 45 W. A high-performance cooling solution is a must for a system built around such a chip.

The R5 6600H is built with TSMC's 6 nm process for great, as of early 2023, energy efficiency.
