AMD Ryzen 7 4800H vs AMD Ryzen 5 4500U

AMD Ryzen 7 4800H

► remove AMD R7 4800H

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.

AMD Ryzen 5 4500U

► remove AMD R5 4500U

The AMD Ryzen 5 4500U is a processor for thin and light laptops based on the Renoir architecture. The 4500U integrates six cores based on the Zen 2 microarchitecture. They are clocked at 2.3 (guaranteed base clock) to 4 GHz (Turbo) without SMT / Hyperthreading support (6 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 Ryzen 5 4600U, the 4500U offers no SMT, but otherwise shoudl perform quite similar. 

With two less cores, the Ryzen 5 4500U 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).
