It's a 8+3 phase with the voltage controller being a true 4 phase on the CPU section doubled to 8 with additional mosfet drivers while the other 3 are for iGPU.
I thought the other three were for the entire system agent, including the memory controller
It's another voltage controller that controls the memory VRM which is a Richtek RT8120. The CPU Core Voltage VRM uses an Intersil 95866 which is a true 4+3 phase which Gigabyte has doubled to 8+3 phase. System Agent and VCCIO use Richtek RT8120D which is 1 phase each.
I didn't mention the memory signal voltage controller, for which the components can usually be seen separated from the group of things for various CPU devices
As for the 4/8, I say split, you say doubled. But getting back to the original message, we were seeing 24+ voltage regulators on P35/P45 boards before someone else (I think MSI) came out with higher capacity parts on a 6-phase design that could do the same work at lower cost. Soon after we were frying 12 phase regulator components and not frying 8 phase components when doing the same thing, because the boards with the 12 phase regulators were using substandard parts. Then some companies put high-amp chokes on low-amp MOSFETs and I blew more boards.Then some companies put high-amp chokes AND MOSFETs on the same board and extreme overclockers blew traces surrounding the MOSFETs. Then some companies used a thicker copper layer on the PCB with higher amp parts and hollow EPS12V pins and I blew out the connector. We even had sockets without enough contact pressure on the pins blowing out. Because of this, the only way I can find the weak point is through testing. And because of that, I'm now treating "phase count" as a matter of trivia.
