AMD Ryzen 9 5900HS vs AMD Ryzen 9 5980HX vs AMD Ryzen 7 5800HS
AMD Ryzen 9 5900HS
► remove from comparisonThe 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 9 5980HX
► remove from comparisonThe AMD Ryzen 9 5980HX (in leaks also known as R9 5980H is a processor for big (gaming) laptops based on the Cezanne generation. The R9 5980HX integrates all eight cores based on the Zen 3 microarchitecture. They are clocked at 3.3 (guaranteed base clock) to 4.8 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured in the modern 7 nm process at TSMC. The "X" in the name indicates the overclocking capabilities of the CPU.
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 5980HX 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.
Power consumption
This Ryzen 9 series chip has a default TDP, also known as the long-term power limit, of 45 W. Laptop makers are free to change that value to anything between 35 W and 54 W, with clock speeds and performance changing accordingly as a result. Either way, a powerful cooling solution is a must for a CPU like this.
The R9 5980HX is built with TSMC's 7 nm process for higher than average, as of late 2022, energy efficiency.
AMD Ryzen 7 5800HS
► remove from comparisonThe 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.
