AMD Ryzen 9 5980HS vs AMD Ryzen 7 5800HS vs AMD Ryzen 9 5900HS

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 in 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 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.

With the increased clock speed and IPC improvements thanks to Zen 3, the Ryzen 7 5800H should be clearly faster than the lower clocked Ryzen 7 4800H.

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.

Power consumption

The Ryzen 7 has a default TDP (also known as the long-term power limit) of 35 W. Which is too much to allow for passively cooled designs.

The APU is built with TSMC's 7 nm process for very decent, as of early 2023, energy efficiency.

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.
