AMD Ryzen 9 5980HS vs AMD Ryzen 9 5900HS vs AMD Ryzen 5 5600H

AMD Ryzen 9 5980HS

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).

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 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.

AMD Ryzen 5 5600H

The AMD Ryzen 5 5600H is a processor for big (gaming) laptops based on the Cezanne generation. The R5 5600H has six of the eight cores based on the Zen 3 microarchitecture. They are clocked at 3.3 GHz (guaranteed base clock) to 4.2 GHz (Turbo) and support SMT for a total of 12 threads. The chip is manufactured on the modern 7 nm TSMC process.

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 six CPU cores, the APU also integrates a Radeon RX Vega 7 integrated graphics processor with 7 CUs running at up to 1800 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 16 MB of L3 cache can be found on the chip.

Performance

The average 5600H in our database is in the same league as the Ryzen 5 6600HS and the Core i7-1260P, as far as multi-thread benchmark scores are concerned.

Thanks to its decent cooling solution and a long-term CPU power limit of 45 W, the Lenovo Legion 5 17 is among the fastest laptops powered by the 5600H that we know of. It can be roughly 30% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

This Ryzen 5 series chip has a default TDP (also known as the long-term power limit) of 45 W, a value that laptop makers are allowed to change to anything between 35 W and 54 W with clock speed and performance changing accordingly as a result. A high-performance cooling solution is a must for a CPU like this.

The hexa-core APU is built with the 7 nm TSMC process for decent, as of late 2022, energy efficiency.
