The AMD Ryzen 7 4800H is a mobile SoC for big laptops based on the Renoir architecture. The 4800H integrates all eight cores based on the Zen 2 microarchitecture. They are clocked at 2.9 (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.
According to AMD, the Ryzen 7 4800H is 5% faster in Cinebench R20 single thread test and 46 % faster in the multithreaded test compared to the Core i7-9750H (thanks to the 2 additional cores). That translates to a performance between a Intel Core i9-9880H and the i9-9980HK top model. The old Ryzen 3000 mobile chips (e.g. Ryzen 7 3750H) are easily bested in CPU-performance thanks to the additional 4 cores, Zen 2 microarchitecture, and higher clock speeds. That means the Ryzen 7 4800H 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 7 integrated graphics card with 7 CUs and up to 1600 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 45 Watt (default) and can be configured to 35 - 54 Watt by the laptop vendor. That means the chip is intended for big and relatively heavy laptops. The Ryzen 7 4800HS is the 35 Watt version of the 4800H with a 10 Watt lower TDP.
The AMD Ryzen 5 4600H is a mobile SoC for big laptops based on the Renoir architecture. The 4600H integrates six of the eight cores based on the Zen 2 microarchitecture. They are clocked at 3 (guaranteed base clock) to 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.
Due to the two deactivated cores and the slower Turbo clock speed, the Ryzen 5 4600H should be significantly slower than the Ryzen 7 4800H. The old top model Ryzen 7 3750H is still clearly slower due to the four Zen+ cores. Compared to the competition, the Intel Core i7-8850H (6-core Coffee Lake 2.6 - 4.3 GHz) should offer a similar performance.
In addition to the six CPU cores, the APU also integrates a Radeon RX Vega 6 integrated graphics card with 6 CUs and 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.
The TDP of the APU is specified at 45 Watt (default) and can be configured to 35 - 54 Watt by the laptop vendor. That means the chip is intended for big and relatively heavy laptops. The similar named Ryzen 5 4600HS is the 35 Watt version of the chip with the same specifications.
