AMD Ryzen 3 5400U
The AMD Ryzen 3 5400U is a processor for thin and light laptops based on the Cezanne generation. The R3 5400U integrates four of the eight cores based on the Zen 3 microarchitecture and is the slowest U-series processor of the Cezanne generation at launch. The cores are clocked at 2.6 (guaranteed base clock) to 4 GHz (Turbo) and support SMT / Hyperthreading (8 threads). The chip is manufactured in the modern 7 nm process at TSMC.
The new Zen 3 microarchitecture offers a significantly higher IPC (instructions per clock) compared to Zen 2. For desktop processors AMD claims 19 percent on average and in applications reviews showed around 12% gains at the same clock speed.
With the increased clock speed and IPC improvements thanks to Zen 3, the Ryzen 3 5400U should be clearly faster than the lower clocked Ryzen 3 4300U.
In addition to the four CPU cores, the APU also integrates a Radeon RX Vega 6 integrated graphics card with 6 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 (same as the old 4800U) can be found on the chip.
The TDP of the APU is specified at 15 Watt (default) and can be configured from 10 to 25 Watt by the laptop vendor (most chips are configured higher than 15 Watt). That means the chip is intended for thin and light laptops (but with fans).
