AMD Ryzen 9 5900HS

The AMD Ryzen 9 5900HS is a processor for big (gaming) laptops based on the Cezanne generation. The R9 5900HS integrates all eight cores based on the Zen 3 microarchitecture. They are clocked at 3 GHz (guaranteed base clock) to 4.6 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured on the modern 7 nm TSMC process. Compared to the 5900HX (up to 54 W), the 5900HS is configured with a TDP of 35 W.

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 iGPU with 8 CUs at up to 2100 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 16 MB of Level 3 cache can be found on the chip.

Performance

The average 5900HS in our database matches Intel Core i7-12650H, Core i9-11900H and Core i9-11980HK in multi-thread performance while, surprisingly enough, coming unbelievably close to the more power-hungry Ryzen 9 5900HX. This is a great CPU in all respects, and most laptop manufacturers as well as many mini-PC manufacturers are taking note.

Power consumption

This Ryzen 9 has a default TDP (also known as the long-term power limit) of 35 W, making it significantly less of a power hog than the 5900H. Either way, an active cooling solution is a must for a CPU like this.

Ryzen 9 5900HS is built with TSMC's 7 nm process for decent, as of late 2022, energy efficiency.
