Hello Okayson, thanks for joining the processor community.
I’m afraid to inform you that upgrading older systems to a Broadwell processor is not going to be possible.
The reason is because all Broadwell processors are in the BGA package, which means that they will be soldered to the motherboard.
Thanks for the prompt response. I would just like to clarify that I am
talking about desktop systems, not laptop systems. I was referring to
upgrading the Mac Pro (cylindrical desktop), which like most desktops I
know come with upgradeable CPUs. Are you saying that starting with
Broadwell, there will be no upgrade for desktops?
