AMD Ryzen 7 5800HS
The AMD Ryzen 7 5800H is a processor for big (gaming) laptops based on the Cezanne generation. The R7 5800H integrates all eight cores based on the Zen 3 microarchitecture. They are clocked at 3.2 (guaranteed base clock) to 4.4 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured in the modern 7 nm process at TSMC. Compared to the 5800H (up to 54 W), the 5800HS is configured to a TDP of 35W.
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 7 5800H should be clearly faster than the lower clocked Ryzen 7 4800H.
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 2000 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 16 MB level 3 cache (up from 8 MB at the 4800U) can be found on the chip.
The TDP of the APU is specified at 35 Watt and therefore suited for smaller laptops than the 5800H (35 - 52W, default 45W).
Beware, the R7 5800HS is not yet released (rumored early 2021) and therefore above information is still based on rumors and leaks like from Geekbench.
