AMD Ryzen 5 6600U

AMD R5 6600U

The AMD Ryzen 5 6600U is a processor for thin and light laptops based of the Rembrandt generation. The R5 6600U packs six of the eight cores based on the Zen 3+ microarchitecture. They are clocked at 2.9 (guaranteed base clock) to 4.5 GHz (Turbo) and support SMT / Hyperthreading (12 threads). The chip is manufactured on the modern 6 nm process at TSMC. Compared to the similar R5 6600H, the 6600U offers a lower base clock speed and a lower TDP.

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.

The processor performance should be clearly better than the old Ryzen 5 5600U thanks to the improved clock speed. However, the new Alder Lake U and P-series CPUs, like the i5-1260P, should offer a higher performance.

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

The TDP of the APU is specified at 15 - 28 Watts (default). The power efficiency should be very good, thanks to the improved 6nm process and additional power saving features in the 6000 series.
