The AMD Ryzen 9 6900HX is a processor for big (gaming) laptops based on the Rembrandt generation. The R9 6900HX 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 "X" in the name indicates the overclocking capabilities of the CPU.
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 2.4 GHz. It should be the fastest iGPU of all at the time of announcement.
Performance
The average 6900HX in our database edges out the Core i7-12800H just slightly while, a little disappointingly, not quite managing to leave the 6900HS behind in the dust. Don't get us wrong; this is still a brilliant CPU for your demanding apps and games, as of late 2022. It does lag behind some of the 12th generation Intel Core i9 options, though.
Thanks to its decent cooling solution and a long-term CPU power limit of nearly 90 W, the XMG Neo 15 2022 is among the fastest laptops built around the 6900HX that we know of. It can be at least 20% 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 with the letter "X" indicating that the user is officially allowed to overclock the thing - leading to an increase in power consumption levels. Either way, a high-performance cooling solution is a must for a CPU like this.
The R9 6900HX is built with TSMC's 6 nm process making for very good, as of early 2023, energy efficiency.
The Intel Core i5-12600H is a high-end mobile CPU for laptops based on the Alder Lake architecture. It was announced in early 2022 and offers 4 of the 6 performance cores (P-cores, Golden Cove architecture) and all 8 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 16 supported threads when combined with the E-cores. The clock rate ranges from 2.7 to 4.5 GHz on the performance cluster and 2 to 3.3 GHz on the efficient cluster. The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6700HQ). All cores can use up to 18 MB L3 cache. Compared to the 12650H, the 12600H offers less P-cores but more E-cores, a faster iGPU and "Enterprise" vPro features (for remote management).
Performance
Thanks to the 12 cores, the multi-threaded performance should be clearly faster than the older Tiger Lake-H CPUs with similar clock speeds (especially like the Core i5-11500H with only 6 cores). Due to the architectural improvements, single-core performance is also better than similar or higher clocked Tiger Lake CPUs.
Features
The integrated memory controller supports various memory types up to DDR5-4800, DDR4-3200, LPDDR5-5200, and LPDDR4x-4267. The Thread Director (in hardware) can support the operating system to decide which thread to use on the performance or efficient cores for the best performance. For AI tasks, the CPU also integrates GNA 3.0 and DL Boost (via AVX2). Quick Sync in version 8 is the same as in the Rocket Lake CPUs and supports MPEG-2, AVC, VC-1 decode, JPEG, VP8 decode, VP9, HEVC, and AV1 decode in hardware. The CPU only supports PCIe 4.0 (x8 for a GPU and two x4 for SSDs).
The integrated graphics card is based on the Xe-architecture and offers 80 of the 96 EUs (Execution Units) operating at up to 1.4 GHz.
The CPU is rated at 45 W base power (95 W PL2) but most laptops will use a PL1 of around 60 Watt. The SoC is manufactured in a 10nm process at Intel, which is known as Intel 7.
