AMD Ryzen 9 6900HS vs AMD Ryzen 5 4600H vs AMD Ryzen 7 6800H
AMD Ryzen 9 6900HS
► remove from comparison
The AMD Ryzen 9 6900HS is a processor for big (gaming) laptops based on the Rembrandt generation. The R9 6900HS integrates all eight cores based on the Zen 3+ microarchitecture. They are clocked at 3.3 (guaranteed base clock) to 4.9 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured on the modern 6 nm TSMC process. The HS variant offers a 10 W lower TDP and therefore a lower sustained performance than the HX version.
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.
Performance
The average 6900HS in our database matches the Intel Core i7-12800H in multi-thread performance while managing to keep up with the more power-hungry 6900HX. "Top of the crop" is precisely the right phrase to describe this Ryzen 9 series chip, as of Q4 2022, and it will have no difficulty ripping through any task imaginable for years to come.
Your mileage may vary depending on how high the CPU power limits are, and how competent the cooling solution of your system is.
A big novelty is the integrated GPU Radeon 680M, that is now based on the RDNA2 architecture and offers 12 CUs at up to 2.4 GHz. It should be the fastest iGPU of all at the time of announcement.
The TDP of the APU is specified at 35 Watts and therefore better suited for thin and light laptops. The power efficiency should be very good, thanks to the improved 6 nm process and additional power saving features in the 6000 series.
AMD Ryzen 5 4600H
► remove from comparison
The AMD Ryzen 5 4600H is a mobile SoC for big laptops based on the Renoir architecture. The 4600H integrates six of the eight cores based on the Zen 2 microarchitecture. They are clocked at 3 (guaranteed base clock) to 4 GHz (Turbo) and support SMT / Hyperthreading (12 threads).
In addition to the six CPU cores, the APU also integrates a Radeon RX Vega 6 integrated graphics adapter with 6 CUs and up to 1500 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 8 MB level 3 cache can be found on the chip. See our hub page on the Renoir Processors for more information.
Performance
The average 4600H in our database matches the Intel Core i7-10875H and even the Core i9-10885H, both significantly more costly chips, in multi-thread performance, giving this Ryzen an outrageously high price-to-performance ratio.
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
The Ryzen 5 chip has a default TDP (also known as the long-term power limit) of 45 W, a value that laptop makers are free to change to anything between 35 W and 54 W with clock speed and performance changing accordingly as a result. Either way, a high-performance cooling solution is a must for a CPU like this.
The 7 nm TSMC process this APU is built with makes for better-than-average, as of early 2022, energy efficiency.
AMD Ryzen 7 6800H
► remove from comparisonThe AMD Ryzen 7 6800H is a processor for big (gaming) laptops based on the Rembrandt generation. The R7 6800H integrates all eight cores based on the Zen 3+ microarchitecture. They are clocked at 3.2 (guaranteed base clock) to 4.7 GHz (Turbo) and support SMT / Hyperthreading (16 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.
A big novelty is the integrated GPU Radeon 680M that is now based on the RDNA2 architecture and offers 12 CUs at up to 2.2 GHz. It should be the fastest iGPU of all at the time of announcement.
Performance
The average 6800H in our database is in the same league as the Core i5-12500H and the Core i7-12650H, as far as multi-thread benchmark scores are concerned. The Ryzen 9 5900HX is found close nearby as well.
Thanks to its decent cooling solution and a long-term CPU power limit of 90 W, the Legion 5 Pro 16ARH7H is among the fastest systems built around the 6800H that we know of. It can be about 60% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.
Power consumption
This Ryzen 7 series chip has a default TDP, also known as the long-term power limit, of 45 W. An active cooling solution is a must for a CPU like this.
The R7 6800H is built with TSMC's 6 nm manufacturing process for above average, as of mid 2023, energy efficiency.
