AMD Ryzen 7 PRO 5850U

The AMD Ryzen 7 PRO 5850U is a processor for thin and light laptops based on the Cezanne generation. The R7 5850U integrates all eight cores based on the Zen 3 microarchitecture and is the fastest U-series processor at launch. They are clocked at 1.9 (guaranteed base clock) to 4.4 GHz (Turbo) and support SMT for a total of 16 processing threads. The chip is manufactured on the modern 7 nm TSMC process.

The PRO CPUs offer additional management and security features. The 5850U is otherwise identical to the Ryzen 7 5800U.

The new Zen 3 microarchitecture offers a significantly higher IPC (instructions per clock) compared to Zen 2. For desktop processors AMD claims 19 percent on average and in applications reviews showed around 12% gains at the same clock speed.

In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 8 graphics processor with 8 CUs at up to 2000 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 16 MB level 3 cache (up from 8 MB at the 4800U) can be found on the chip.

Performance

The average 5850U in our database matches Ryzen 7 5700U, Ryzen 7 4800U, Ryzen 7 5800U, Intel Core i7-1260P and Core i7-1270P in multi-thread performance. In other words, this is a very capable U-class APU that creeps in front of many H-class processors.

Power consumption

This Ryzen 7 has a default TDP (also known as the long-term power limit) of 15 W. That is a tad too high to allow for passively cooled designs. Furthermore, most laptop manufacturers will go for even higher values to allow for higher performance levels. Say, 23 W or 30 W.

Ryzen 7 PRO 5850U is built with TSMC's 7 nm process for very decent, as of late 2022, energy efficiency.
