I think the chance of having intel is higher than having Kyro, which is from Qualcomm.There is nothing wrong with ARM architecture. In a sense it's much more efficient than going with desktop architecture. It's also a good industry standard but missing those Denver cores is going to make a big hit for performance IMO.
I'd be happy if they used something like 4x ARM Kryo cores. Something that is a bit more powerful but still used in the latest flagship Android devices.
Arm still has a72/ a73, which are slower but more power efficient than Denver 2 (especially a73). If I recall correctly ARM has a much bigger ISA than x86.
