AMD Ryzen 9 4900H

The AMD Ryzen 9 4900H is a mobile SoC for big laptops based on the Renoir architecture. At the time of announcement in March 2020 it is the fastest model of the 4000H series. The R9 4900H integrates all eight cores based on the Zen 2 microarchitecture. They are clocked at 3.3 (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 and partly thanks to it AMD advertises a 2x improved performance per Watt for the Renoir chips

According to our information, the Ryzen 9 4900H is only slightly faster than the Ryzen 7 4800H. The CPU is clocked 400 MHz (base +14%) to 200 MHz (boost +5%) higher, but the gains greatly depend on the cooling and TDP settings. Compared to Intel chips, the i9-9980HK top model should be comparable. That means the Ryzen 9 4900H should be able to handle all demanding tasks and gaming.

In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 8 integrated graphics card with 8 CUs. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 12 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 45 Watt (default). That means the chip is intended for big and relatively heavy laptops.
