AMD Ryzen 7 4800U vs AMD Ryzen 5 4600U
AMD Ryzen 7 4800U
► remove from comparison
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).
AMD Ryzen 5 4600U
► remove from comparisonThe 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).
