AMD Ryzen 5 6600HS

The AMD Ryzen 5 6600HS is a processor for big (gaming) laptops based of the Rembrandt generation. The R5 6600HS 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 HS variant is notable for its 10 W lower TDP than the usual 45 W and therefore a lower sustained performance than the H version.

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.

Performance

The average 6600HS in our database pretty much matches the Ryzen 5 5600H, the Ryzen 7 5800U and also the Core i7-1260P in multi-thread performance. Whish if fairly impressive, as of late 2022.

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

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

The TDP of the APU is specified at 35 Watts making the Ryzen 5 better suited for thin and light laptops. The power efficiency should be very good, thanks to the improved 6nm process  and additional power saving features in the 6000 series.
