There are only a few days left for the presentation of the new AMD APUs for 2022, which will surely receive the names of 6000U, 6000H and 6000G in their different versions. Well, some new details have just been filtered that give us a better idea of what Lisa Su is up to for laptops for this year. So let’s see what to expect from Rembrandt APUs.
If we look closely, Intel has upgraded its APUs to its newer technologies in two generations. In the first under the Cézanne or Ryzen 5000 architecture, the Zen 3 architecture was implemented, now with Rembrandt we are going to see changes in the rest of the processor and the vast majority of them are very important, because they are reflected by a significant jump in performance.
These would be the changes for AMD Rembrandt APUs
Due to the constant flow of information, many of them will be familiar to you already, as is the case with DDR5 memory support, which will mean a new Unified Memory Controller or UMC designed to support loads the new standard of memory, being the first AMD processor in the dozen. In total up to 4 channels of DDR5 memory. On the other hand, some models will have LPDDR5 support.
The second point to note concerns the interfaces of peripheral devices integrated into the CPU. We have 3 sets of 4 PCI Express 4.0 lanes interfere with motherboard chipset or NVMe SSDs and 8 lines of the same type for a graphics card that you want to connect to the system. So, as it has been said for months, AMD has decided do not adopt PCIe Gen 5 at this time. Also noteworthy is the support for 10 GB EthernetAlthough only for Linux, let’s not forget that fiber optics at these speeds are getting closer and closer. As for the support of USB ports, we can see how they were added. 2 USB 4.0 ports
Although the highlight of all is the change in architecture of the integrated GPU. We will finally say goodbye to GCN Vega to adopt RDNA or Navi, in particular with a configuration of 6 WGP or 12 compute units, being the highest of an AMD APU to date. A higher than expected figure which leads us to wonder if some products have not put the throttle too early when it comes to adopting an AMD APU in their systems.
AMD also joins TDP’s 28 W
AMD manufactures its Ryzen 6000 APU under TSMC’s 6nm node, which enables up to 18% higher density than the 7nm used by current AMD processors. However, everything indicates that the size could be much bigger and all because of the adoption of new DDR5 interfaces, peripherals like USB 4.0, iGPU with more advanced architecture like RDNA 2 and all. this we can not forget about the improvements of the CPU Zen 3.
We will have two versions of the Rembrandt or Ryzen 6000 APUs, the first will use the FP7 packaging and the second the FP7r2. The size at first glance will be the same, but they will differ in that the first type will support DDR5 memory and hence the RAM of said laptops will come SO-DIMMs, the second type will support soldered LPDDR5 memory.
If we look at the list before this section, we can see how AMD, like Intel, also adopted the standard of 28 W of TDP for its Rembrandt APU. It is surprising not to see an AMD Rembrandt 15W APU. The fact that AMD has also adopted the new TDP standard that its rival means that we are going to see a lot of models with variants from Intel and AMD under the same form factor.
