AMD's upcoming desktop APU is expected to feature Zen 4 architecture, but recent BIOS code updates suggest that the company may be planning to use Zen 5 instead. This would be a significant improvement over the current Zen 3 architecture, offering higher performance and power efficiency.

The new APU is expected to feature a maximum of 12 cores and 24 threads, making it a powerful option for gaming and content creation. The APU will also feature a new PCIe interface, which may offer improved performance and compatibility with newer hardware.

AMD's Strix Point APU is also rumored to be in the works, which could offer even higher performance and features. However, it's unclear whether this APU will be compatible with the AM5 platform or if it will require a separate socket.

The rumors and speculations surrounding AMD's next-generation APU are exciting, but it's essential to wait for official announcements from the company to confirm the details. In the meantime, we can only speculate about the possibilities and potential benefits of these new APUs.
