AMD Ryzen 5 6600U

The AMD Ryzen 5 6600U is a processor for thin and light laptops based of the Rembrandt generation. The Ryzen 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.

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 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 6600U in our database matches Ryzen 7 5800U in multi-thread performance, highlighting benefits of the updated architecture and making this Ryzen 5 a great CPU for mid-range laptops of the thinner, lighter kind.

Power consumption

This Ryzen 5 series chip has a default TDP, also known as the long-term power limit, of 15 W to 28 W, the expectation being that laptop makers will go for a higher value in exchange for higher performance. Either way, that's too much to allow for passively cooled designs.

The R5 6600U is manufactured on TSMC's 6 nm manufacturing process for good, as of mid 2023, energy efficiency.
