AMD Ryzen 5 PRO 4650U

The AMD Ryzen 5 PRO 4650U is a processor for thin and light laptops based on the Renoir architecture. The 4650U integrates six cores based on the Zen 2 microarchitecture. They are clocked at 2.1 (guaranteed base clock) to 4 GHz (Turbo) with SMT for a total of 12 threads. The chip is manufactured on the modern 7 nm TSMC process and partly thanks to it AMD advertises a 2x improved performance per Watt for the Renoir chips.

The PRO processors offer a range of business features like hardware security (e.g., AMD Memory Guard), manageability (e.g., support for Microsoft Endpoint Manager), and longer availability and software stability.

In addition to the six CPU cores, the APU also integrates a Radeon RX Vega 6 integrated graphics adapter with 6 CUs at up to 1500 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 8 MB level 3 cache can be found on the chip. See our hub page on the Renoir Processors for more information.

Performance

The average 4650U in our database is just as fast as the Intel Core i7-11375H and the AMD Ryzen 5 4600U are in multi-thread workloads. This is a fairly decent mid-range CPU, as of late 2021.

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 chip has a default TDP (also known as the long-term power limit) of 15 W. Which is a tad too high to allow for passively cooled designs, besides, laptop makers aren't really obliged to stick to it.

The AMD Ryzen 5 PRO 4650U is manufactured on TSMC's 7 nm process, leading to average, as of mid 2023, energy efficiency.
