One of AMD’s primary selling points has always been the extended platform support offered by the AM4 socket. A $50 A320 motherboard from 2017 can be paired with the Ryzen 7 5800X3D in 2022 to build a supercharged gaming PC with minimal effort or expense. The chipmaker promises similar durability and flexibility to owners of the X670/B650 boards. Promising support for the next-gen (Zen 5) processors along with their 3D V-Cache options, Team Red is taking a shot at its opponent.
The competition, on the other hand, makes no commitments to future upgrade support on their latest LGA 1700 platform. Intel has consistently limited platforms to one or two processors, so users who buy a 12th or 13th Gen Intel Core platform will likely have to spend a lot more money on a whole new motherboard if they want to upgrade to a 14th Gen processor or beyond.AMD
Intel likely has no plans to retain its upcoming 14th Gen Core processors on existing 600/700 series boards, blocking users from a future upgrade path. Investing in a new motherboard means paying at least 40-50% more for the upgrade, drastically increasing your investment and leaving no room for experimentation.

AMD goes on to compare the PCIe bandwidth of Intel’s flagship Z790 against its midrange B650E chipset:
As you can see, the latter offers twice as much bandwidth in heavily populated systems. Installing a Gen 5 graphics card and an NVMe SSD on a 13th Gen Core PC can limit the former’s bandwidth to 50% of the promised figure. You should know that even a PCIe Gen 4 x8 connection is sufficient for most discrete graphics cards. A Gen 5 x8 bus is more than sufficient for the foreseeable future.

|FUTURE GENERATION CPU SUPPORT COMMITMENT?|
|AMD B650E & X670E||24||16||YES|
|INTEL X790 and X690||16||8||NO|
Last but not least, AMD does have a clear I/O advantage across all segments. The B650E and X670E boards come with 24 PCIe Gen 5 lanes, allowing the graphics card to utilize all 16 over the Gen 5 protocol.
