Today we have an interesting leak for those who are expecting next-gen AMD laptops with the Rembrandt Ryzen 6000 APU like the Ryzen 9 6900HX.
High-performance AMD laptops with Ryzen 9 6900HX ‘Rembrandt’ APUs to pack 8 upgraded Zen 3 cores in a 6nm process and a Radeon 680M ‘RDNA 2’ iGPU
Our sources have told us quite a lot about the AMD Rembrandt APUs, especially the Ryzen 9 6900HX, which will be one of the fastest Ryzen 6000 chips in the pack. AMD’s new line of APUs will replace the Ryzen 5000 ‘Cezanne’ series and will feature an update for CPU and GPU IPs.
On the CPU side, AMD’s Ryzen 9 6900HX APU will offer 8 cores and 16 threads. These cores are based on the new Zen 3+ architecture, which is an upgraded version of the Zen 3 core but with the latest 6nm TSMC toggle. The new compute node would allow AMD to extract more juice from your laptop’s chips while running efficiently. As for the cache, the chip will come with 16MB of L3 cache and 4MB of L2 cache. For those hoping for 3D V-Cache technology in laptops, that won’t happen for a few more generations.
In terms of clock speeds, the maximum boost clock for the chip will be rated at 4.6 GHz, which is the same as the current Ryzen 9 5900HX, but we can expect the Ryzen 9 6900HX to consume less power. The CPU will allow DDR5-4800 memory support in laptops, which will bring a massive increase in bandwidth over DDR4 memory.
The GPU side for the AMD Rembrandt Ryzen 9 6900HX will see a major update. AMD will be using their RDNA 2 core architecture and while we were not told how many RDNA 2 CUs we will get on the new chips, we are being told that the red team has decided to change the nomenclature of their integrated RDNA graphics. Starting from Rembrandt, AMD will use the Radeon 6 ** M brand. The particular iGPU variant for the Ryzen 9 6900HX will be called the Radeon 680M. The addition of DDR5 plays a crucial role for integrated graphics as RDNA 2 loves raw bandwidth and the extra juice from the new memory standard will definitely help here.
But since the AMD Ryzen 9 6900HX will be aimed at high-performance laptops, we are told that most designs that will pack this APU inside will be equipped with NVIDIA’s best GeForce GPUs, such as the RTX 3070 Ti. (8 GB) and RTX 3080 Ti (16 GB). We’ve already seen some ASUS designs leak before, including their ROG Zephyrus and ROG STRIX. Expect more information from AMD at the CES 2022 virtual keynote address.
