It is shipping now.
It is called Centriq.
And it is designed by Qualcomm.
Manufactured by Samsung in 10nm process.

Intel has close to 100% of the server market.
Competitors like AMD, IBM and Oracle are just rounding errors.
Centriq may be able to eat into Intel's lunch if it can prove its claims that it can match Xeon's performance for less power.

Here's the juicy info:
  • Fabricated using Samsung's 10nm FinFET process with 18 billion transistors on a 398mm2 die in a system-on-chip package.
  • Up to 48 single-thread cores running at 2.2GHz, peaking to 2.6GHz.
  • It is 64-bit-only: there is no 32-bit mode.
  • The cores are connected internally on a bidirectional ring bus with an aggregate bandwidth of 250GBps.
  • 512KB of shared L2 cache for every core pair on the bus.
  • 60MB of unified L3 cache spread out along the ring interconnect.
  • Six DDR4 RAM channels that can interface up to 768GB of memory per processor.
  • 32 PCIe gen-3 lanes and six controllers.
  • ARM TrustZone for secure boot.
  • A power draw of up to 120 watts.
  • A $1,995 price tag for the 48-core part.
