AMD generation Ryzen, 7th generation / 8th generation APU (Raven Ridge), Ryzen 2000 (Pinnacle Ridge) have one thing in common, namely shared AM4 interface. Although it is a gorgeous two different types of products, two generations, however, the motherboard Still the A320, B350 and X470 three models.
This means that even if you are the first batch of B350 users, you only need to upgrade the BIOS to switch seamlessly between the four CPUs.
However, this kind of "conscience" compatibility also has some problems in the actual operation.
For example, in the early days of the 8th generation APU, some users found that the old motherboard had a bug that had no solution because updating the BIOS had to light the system, and they had only new processors at hand. For this purpose, AMD allowed related users to apply for boot kits (Boot) Kit), there is a 7-generation APU inside, we get the boot and upgrade to support 8 generations of APU's BIOS, and then consciously return the kit to the factory.
Another example is the motherboard BIOS update progress is not the same, and manufacturers always give priority to the high-end X470, followed by the B350/A320. Once the problem occurs, netizens always target AMD. Things have become more serious after the release of the Ryzen 2000 processor..
In order to stimulate sales in the absence of a new chipset, motherboard makers made a small change to the X470/B350 to attract users. They bought a boss or waited for a smooth upgrade and went to bed. No new BIOS.
After foreign media TechSpot analyzed the problem, AMD is likely to give up the maintenance of AM4 compatibility and follow Intel's only two generations of routines.
The so-called maintenance of only two generations means that historically, SNB/IVB motherboards are compatible, Haswell/Broadwell motherboards are compatible, and Skylake/Kabylake motherboards are compatible. Although CoffeeLake is consistent with the 6th/7th generation of Core Duo, it has been mercilessly strangled by Intel. Has been cracked, but changing the BIOS is not easy.
TS also understands Intel's approach. It seems that the user is the 'damage' of choice, but it reduces a lot of trouble, but also to take care of the numerous white users.
In the official caliber of AMD, the AM4 interface will continue until 2020. This may be the end of the fourth-generation compatible strategy. In addition, we have not talked about the pressure of DDR5, PCIe 4.0 on the AM4 interface.
