AMD Ryzen 9 6900HX
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.
The processor performance should be a bit higher than the old Ryzen 9 5980HX thanks to the higher boost clock (+100 MHz). The new Alder Lake mobile CPUs with 14 cores (like the Core i9-12900HK) should however offer a higher multi-core performance. Compared to the fastest model, the Ryzen 9 6980HX, the 6900HX offers a 100 MHz lower Boost clock and therefore a slightly lower performance.
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 45 Watts (default) and can be configured higher for the X series CPUs if an OEM so desires. The power efficiency should be very good, thanks to the improved 6 nm process and additional power saving features in the 6000 series.
