AMD Ryzen 5 PRO 6650U

The AMD Ryzen 5 PRO 6650U is a processor for thin and light laptops based of the Rembrandt generation. The Ryzen has six out of a possible 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 TSMC process. The Ryzen 5 PRO 6650U is the professional version of the consumer R5 6600U with additional management features and the Microsoft Pluton Security processor. Compared to the similar R5 6650H, the 6850U 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.

Performance

The average 6650U in our database is very close to the Core i7-1260P and the Core i7-10870H, as far as multi-thread benchmark scores are concerned. This is a really good result, as of late 2022.

Thanks to its decent cooling solution and a long-term CPU power limit of 32 W, the ThinkPad T16 G1 is among the fastest laptops built around the 6650U that we know of. It can be about 20% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

In the 6000 series, AMD finally switched to the current RDNA 2 graphics architecture for the iGPU. The 6650U 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.
