AMD Ryzen 9 5900HX vs AMD Ryzen 5 6600H

AMD Ryzen 9 5900HX

► remove from comparison AMD R9 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 benchmark scores are 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, as of mid 2022.

Thanks to its decent cooling solution and a long-term CPU power limit of 80 W, the Strix Scar 17 G733QSA-XS99 is among the fastest laptops powered by the 5900HX that we know of. It can be roughly 15% 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 45 W, a value that laptop makers are allowed to change to anything between 35 W and 54 W with clock speeds and performance changing accordingly as a result. Either way, a high-performance cooling solution is a must for a CPU like this.

The R9 5900HX is built with the 7 nm TSMC manufacturing process resulting in decent, as of late 2022, energy efficiency.

AMD Ryzen 5 6600H

► remove from comparison AMD R5 6600H

The AMD Ryzen 5 6600H is a processor for big (gaming) laptops based of the Rembrandt generation. The R5 6600H integrates six of the eight cores based on the Zen 3+ microarchitecture. They are clocked at 3.3 (guaranteed base clock) to 4.5 GHz (Turbo) and support SMT / Hyperthreading (12 threads). The chip is manufactured on the modern 6 nm TSMC process. 

The new Zen 3+ is a refresh of the Zen 3 architecture and should not offer a lot of changes. The chip itself however, offers a lot of new features, like support for USB 4 (40 Gbps), PCI-E Gen 4, DDR5-4800MT/s or LPDDR5-6400MT/s, WiFi 6E, Bluetooth LE 5.2, DisplayPort 2, and AV1 decode.

In the 6000 series, AMD finally switched to the current RDNA 2 graphics architecture for the iGPU. The 6600H only offers the slower Radeon 660M with 6 of the 12 CUs enabled and 1.9 GHz max. clock speed.

Performance

The average 6600H in our database is in the same league as the R7 5825U, the R7 6800U and also the Core i5-1340P, as far as multi-thread benchmark scores are concerned. This is a very decent result, as of late 2022.

Your mileage may vary depending on how high the CPU power limits are, and how competent the cooling solution of your system is.

Power consumption

This Ryzen 5 series APU has a default TDP, also known as the long-term power limit, of 45 W. A high-performance cooling solution is a must for a system built around such a chip.

The R5 6600H is built with TSMC's 6 nm process for great, as of early 2023, energy efficiency.
