AMD Ryzen 9 4900H vs AMD Ryzen 5 4600HS

AMD Ryzen 9 4900H

► remove AMD R9 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.

AMD Ryzen 5 4600HS

► remove AMD R5 4600HS

The AMD Ryzen 5 4600HS is a mobile SoC for big laptops based on the Renoir architecture. The 4600HS 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 (12 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 5 4600H, the 4600HS is the power efficient version with a TDP of 35 Watt (10 Watt less).

Due to the two deactivated cores and the slower Turbo clock speed, the Ryzen 5 4600HS should be significantly slower than the Ryzen 7 4800HS. 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 35 Watt (default). Although the TDP is 10 Watt lower than the Ryzen 5 4600H, the chip is still intended for big and relatively heavy laptops.
