AMD R7 4800U is zen 2 architecture, 8 cores and 16 threads, clocked at 1.8GHz, acceleration frequency can reach 4.2GHz, core display is 8 cores, TDP is 15W.
It is very important to choose r5 5500u or r74800u! You will know after reading http://www.adiannao.cn/dy
R5 5500U integrates six cores based on the Zen 2 microarchitecture. Their frequencies range from 2.1 (guaranteed base frequency) to 4 GHz (Turbo), and support SMT/Hyper-Threading (12 threads). The chip is manufactured at TSMC using a modern 7-nanometer process. Compared with the older Ryzen 5 4500U (Renoir), the Ryzen 5 5500U provides hyper-threading. The faster Ryzen 5 5600U is already based on the updated Zen 3 architecture.
How about AMD Ryzen R5 5500U? What level of level is it equivalent? The performance should be slightly higher than the old Ryzen 5 4500U (due to SMT support).
In addition to six CPU cores, APU also integrates Radeon RX Vega 7 integrated graphics, with 7 CUs and a frequency of up to 1800 MHz. The dual-channel memory controller supports DDR4-3200 and energy-efficient LPDDR4-4266 RAM. In addition, the chip is also equipped with an 8 MB level 3 cache.
The TDP of the APU is specified as 15 watts (default)
