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 / Hyperthreading (16 threads). The chip is manufactured in the modern 7 nm process at TSMC.
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.
With the increased clock speed and IPC improvements thanks to Zen 3, the Ryzen 7 PRO 5850U should be clearly faster than the 200 MHz lower clocked Ryzen 7 4800U.
In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 8 integrated graphics card with 8 CUs and up to 2000 MHz (or 1900 MHz according to the Geekbench leak). 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.
The TDP of the APU is specified at 15 Watt (default) and can be configured from 10 to 25 Watt by the laptop vendor (most chips are configured higher than 15 Watt). That means the chip is intended for thin and light laptops (but with fans).
