As the owner of an AM4 Aorus Master, I have to say I was very disappointed by this AM5 Aorus Master. Very disappointed. Here are a few things I've noticed when perusing the Gigabyte site and looking at the feature set. (Please let me know if I've missed something here...!)
1) No backpanel Clear CMOS button--gone! I've used it a lot on the x570 Master. Why would GB think that people might actually prefer opening up the case and setting a jumper for every Clear CMOS? Huge step backwards.
2) Dual bios, mechanically switched, on the AM4 Master--Gone in the AM5 Master. That was a compelling feature for me.
3) The AM5 Master has the same audio codec as the AM4 Master--but GB has removed the hardware SABRE DAC, along with the hardware headphone amp. Result is inferior headphone sound compared to the AM4 Master, by a healthy margin.
4) The AM5 Master loses a Lan port, but gains an extra .M2 slot, compared to the AM4 Master. That's a wash, or maybe better than the AM4, depending on your point of view.
5) Last but not least, the AM4 Master is an ATX mboard while the AM5 Master is an E-ATX, so I'd need a new case for it on top of everything else.
There are a few more obvious deficiencies when compared to the AM4 Master, but those are the main ones that I recall. The Kicker? To get the feature set I love about the AM4 Master, I would have to swing for the $800 Aorus Xtreme! That's really pathetic Gigabyte.
It all makes sticking with AM4 a bit longer a much more attractive proposition...😉
