VIA's CenTaur division sprung an unexpected surprise in the CPU industry with its new CHA x86-64 microarchitecture and an on-die NCORE AI co-processor. This would be the first globally-targeted x86 processor launch by a company other than Intel and AMD in close to 7 years, and VIA's first socketed processor in over 15 years. SemiAccurate scored a look at mock-up of the CenTaur CHA NCORE 8-core processor and it turns out that the chip is indeed socketed.
Pictured below, the processor is a flip-chip LGA. We deduce it is socketed looking at its alignment notches and traces for ancillaries on the reverse-side (something BGAs tend to lack). On the other hand, the "contact points" of the package appear to cast shadows, and resemble balls on a BGA package. Topside, we see an integrated heatspreader (IHS), and underneath is a single square die. CenTaur built the CHA NCORE on TSMC's 16 nm FinFET process. The package appears to have quite a high pin-count for a die this size, but that's probably because of its HEDT-rivaling I/O, which includes a quad-channel DDR4 memory interface and 44 PCI-Express gen 3.0 lanes.
