AMD Ryzen 7 4800U

The AMD Ryzen 7 4800U is a processor for thin and light laptops based on the Renoir architecture. The 4800U integrates all eight cores based on the Zen 2 microarchitecture. They are clocked at 1.8 (guaranteed base clock) to 4.2 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured in the modern 7 nm process at TSMC and partly thanks to it AMD advertises a 2x improved performance per Watt for the Renoir chips. Compared to the similar named Ryzen 7 4800H, the 4800U offers a lower TDP (15 versus 45 Watt) and base clock (1.8 versus 2.9 GHz).

According to AMD, the Ryzen 7 4800U is 4% faster in Cinebench R20 single thread test and 90 % faster in the multithreaded test compared to the fast Intel Core i7-1065G7 (Ice Lake, 4 cores, 3.9 GHz). This means the CPU should be one of the fastest processors in the 15 Watt TDP range and well suited for demanding tasks. The sustained performance however ist strongly depending on the cooling system and the TDP settings of the laptop.

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 1750 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.

The TDP of the APU is specified at 15 Watt (default) and can be configured from 10 to 25 Watt by the laptop vendor. That means the chip is intended for thin and light laptops (but with fans).
