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

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 9 5900HX

The AMD Ryzen 9 5900HX is a processor for big (gaming) laptops based on the Cezanne generation. The R9 5900H integrates all eight cores based on the Zen 3 microarchitecture. They are clocked at 3.3 (guaranteed base clock) to 4.6 GHz (Turbo) and support SMT for a total of 16 threads. The chip is manufactured on the modern 7 nm TSMC process. 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.

In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 8 integrated graphics adapter 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.

Performance

The average 5900HX in our database trades blows with Intel's Core i9-11980HK, as far as multi-thread performance is concerned. While not much faster than the less power-hungry Ryzen 9 5900HS, this is still a great CPU for quality gaming laptops as well as DTRs and high-performance mini-PCs.

Power consumption

This Ryzen 9 has a default TDP of 45 W (also known as the long-term power limit), a value that laptop manufacturers are allowed to change to anything between 35 W and 54 W with clock speeds and performance changing accordingly. Either way, a high-performance cooling solutions is a must for a CPU like this.

Ryzen 9 5900HX is built with the relatively modern 7 nm TSMC process resulting in very decent, as of late 2022, energy efficiency.

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.
