AMD Ryzen 9 4900HS vs AMD Ryzen 5 4600U
AMD Ryzen 9 4900HS
► remove from comparison
The AMD Ryzen 9 4900HS is a mobile SoC for big laptops based on the Renoir architecture. The 4900HS integrates all eight cores based on the Zen 2 microarchitecture. They are clocked at 3 (guaranteed base clock) to 4.3 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 4900HS is only slightly faster than the Ryzen 7 4800HS. The CPU is clocked 100 MHz (base and boost) 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 4900HS should be able to handle all demanding tasks and gaming. Compared to the similar named 45W-version, the Ryzen 9 4900H, the 4900HS is differs in 100 MHz boost and 300 MHz base clock.
In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 7 integrated graphics card with most likely 7 CUs. 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). That means the chip is intended for big and relatively heavy laptops. The Ryzen 7 4900HS is the 35 Watt version of the R9 4900H with a 10 Watt lower TDP.
AMD Ryzen 5 4600U
► remove from comparison
The AMD Ryzen 5 4600U is a processor for thin and light laptops based on the Renoir architecture. The 4600U integrates six cores based on the Zen 2 microarchitecture. They are clocked at 2.1 (guaranteed base clock) to 4 GHz (Turbo) with SMT / Hyperthreading support (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.
With two less cores, the Ryzen 5 4600U is clearly slower than the Ryzen 7 4700U and 4800U in multi threaded workloads. However, it should still beat the fastest 15 Watt Ice Lake Intel Core i7-1065G7 (4 cores, 3.9 GHz). Thanks to the 4 GHz Boost clock, the single core performance should be similar. Therefore, the Ryzen 5 4600U is a very fast 15 Watt CPU and clearly faster than the old Ryzen 7 3700U.
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 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).
