AMD Ryzen 7 5800HS

The AMD Ryzen 7 5800HS 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 2.8 (guaranteed base clock) to 4.4 GHz (Turbo) and support SMT for a total of 16 threads. The chip is manufactured on the modern 7 nm TSMC process. 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.

In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 8 integrated graphics adapter with 8 CUs (512 shaders) at up to 2,000 MHz. The dual channel memory controller supports dual-channel DDR4-3200 and quad-channel LPDDR4-4266 energy efficient RAM. Furthermore, 16 MB level 3 cache (up from 8 MB at the 4800U) can be found on the chip.

Performance

While we have not tested a single system built around the 5800HS as of August 2023, we have tested several laptops featuring the 5800H, a chip with very similar specs (Cezanne, 8 cores, 16 threads, up to 4.4 GHz). Based on that, we fully expect the 5800HS to be just slightly slower than the Core i5-12500H, Core i7-11800H, Core i7-12650H, Core i9-11950H and also the AMD Ryzen 9 4900H, as far as multi-thread benchmark scores are concerned. Which is pretty damn fast, as of late 2022.

Your mileage may vary depending on how competent the cooling solution of your system is, and how high the CPU power limits are.

Power consumption

The Ryzen has a default TDP, also known as the long-term power limit, of 35 W. A proper cooling solution is a must for a CPU like this.

This Zen 2-based APU is built with TSMC's 7 nm process for average, as of mid 2023, energy efficiency.
