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 the Core i7-12650H, the Core i9-11900H and the Core i9-11980HK in multi-thread performance. Surprisingly enough, it manages to come unbelievably close to the more power-hungry Ryzen 9 5900HX. This is a great CPU in all respects, and laptop makers as well as mini-PC manufacturers are taking notice.
Thanks to its decent cooling solution and a long-term CPU power limit of 80 W, the Zephyrus G14 GA401QEC is among the fastest laptops powered by the 5900HS that we know of. It can be at least 10% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.
Power consumption
This Ryzen 9 series chip has a default TDP (also known as the long-term power limit) of 35 W that laptop makers aren't really required to stick to. Either way, an active cooling solution is a must for a CPU like this.
The Ryzen 9 5900HS is built with TSMC's 7 nm process for average, as of mid 2023, energy efficiency.
The AMD Ryzen 9 5980HS is a processor for big (gaming) laptops based on the Cezanne generation. The R9 5980HS integrates all eight cores based on the Zen 3 microarchitecture. They are clocked at 3 GHz (guaranteed base clock) to 4.8 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured on the modern 7 nm process at TSMC. Compared to the 5980HX (up to 54 W), the 5980HS is configured to a TDP of 35W and offers a 300 MHz reduced base speed.
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 9 5980HS should be clearly faster than the lower clocked Ryzen 9 4900H.
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 2100 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 16 MB level 3 cache can be found on the chip.
The TDP of the APU is specified at 35 Watt and therefore suited for smaller laptops than the 5980HX (35 - 52W, default 45W).
