Ryzen 7000 (Raphael) processors have proven to be some of the best CPUs on the market. The only AMD chip currently on the AM5 socket. However, that could change soon.according to table (opens in new tab) Since last year’s Gigabyte hack (we recommend throwing a little salt on this one), AMD’s Rembrandt and Phoenix APUs have moved from mobile to desktop, potentially offering two new tenants on the AM5 socket. I have.
The leaked information reportedly points to three variants of Ryzen processors using the AM5 socket. They all belong to the processor family 19h, which consists of AMD’s Zen 3, Zen 3+ and Zen 4 chips. We can see that Type 2 (models 60h-6Fh) refers to the Ryzen 7000 lineup. This is because the Zen 4 based chip features the “A60F12” CPU ID. Type 2 specs such as 28 PCIe lanes made it clear right away.
Type 1 (models 40h-4Fh) and Type 3 (models 70h-7Fh) processors are not currently released. We believe that Type 1 is the Ryzen 6000 series (Rembrandt) and Type 3 is the Ryzen 7040 series (Phoenix), mobile APUs already announced by AMD. Rembrandt’s CPU ID is “A40F41”. Phoenix should be “A70F71”. Phoenix is targeting Ultra Thing laptops and is set to enter the retail market. However, we have not seen any chips in public databases to back up the CPU ID.
Rembrandt comes with Zen 3+ cores and RDNA 2 graphics. TSMC is manufacturing Rembrandt for AMD at his 6nm node in the foundry. Phoenix, on the other hand, is a more exciting prospect. Powered by TSMC’s 4nm node, Phoenix pairs AMD’s latest Zen 4 cores with his RDNA 3 graphics. The chip also features XDNA technology, an FPGA-based AI engine acquired by AMD when it acquired Xilinx. AMD’s previous desktop APUs such as the Ryzen 7 5700G stuck to octa-core configurations. Mobile Rembrandt and Phoenix are up to 8 cores and 16 threads, so this recipe fits AMD’s desktop APUs.

Like Raphael, Rembrandt and Phoenix also support DDR5 memory and support up to two memory modules per channel. Consumers wanted the latest in his APUs that could take advantage of DDR5. AMD APU’s frenzy for fast memory is well documented, so it will be interesting to see how much we can benefit from his fast DDR5 memory.
However, there are some features consumers miss out on in Rembrandt and Phoenix, such as PCIe 5.0 connectivity.Rembrandt and Phoenix only support PCIe 4.0, so you won’t be able to take advantage of PCIe 5.0 SSDs in your desktop. Scalability and connectivity are also slightly limited. Raphael offers 28 PCIe lanes, while Rembrandt and Phoenix offer only 20 lanes, 29% less.
Connectivity options clearly differ between the three different Ryzen processor families. According to the leaked table, one variant of Rembrandt (model 40h) offers three USB 3.2 Type-C ports, while another variant (model 44h) offers two USB 4 ports and one USB 3.2 Type-C port. Provides a C port. Additionally, Phoenix will reportedly feature two USB 4 ports and one USB 3.2 Typ-C port.
Granted, AMD hasn’t given APUs as much love as they’ve given them over the past few generations. APU stagnated around Zen 3. The last APU that AMD launched for him in 2021 was the Ryzen 5000G (Cezanne) series. So his APU from AMD deserves an upgrade and we hope Phoenix can provide it.
