Intel’s is now ramping volume on its Ice Lake-SP CPU, but die photographs of its observe-up generation, Sapphire Rapids, have presently leaked. To speedily recap: Up right until now, Intel’s desktop and server processors have both of those been primarily based on 14nm CPUs. Ice Lake-SP is Intel’s 1st 10nm server solution and it makes use of the Sunny Cove CPU main.
Sapphire Rapids is the follow-up to Ice Lake-SP, and it’s not anticipated right until 2022-2023. Next Intel’s nomenclature, it would be made on the 10nm++ method, and it is envisioned to use the same Willow Cove CPU architecture that powers Intel’s Tiger Lake cell chips. The images underneath ended up produced by YuuKi_AnS:
A resource has verified to THG that the chip is a Sapphire Rapids A2 sample, with 28 enabled CPU cores. We’re searching at LGA4677, if the rumors are correct. Ice Lake-SP makes use of LGA4189, but it’s not stunning for Intel to swap to a new socket at the exact time they add DDR5, PCIe 5., and chiplets. Prior leaks have also proposed at the very least some Sapphire Rapids products will assist HBM memory. This would most likely be confined to precise SKUs, on the other hand, considering the fact that the HBM has to be built-in on-package.
Presented that the LGA4677 socket is believed at about 72mm x 54mm, there’s no way for the chiplets earlier mentioned to be just about anything less than big. A lot greater, in simple fact, than just a seven-main CPU array can account for. THG’s sources assert that Intel has packaged up to 14 cores per chiplet, for a complete of 56 cores available. This is of course an early, engineering sample processor, so only acquiring 28 of the cores lively wouldn’t be regarded uncommon.
One intriguing difference between the AMD CPUs and this ES CPU is the gap — or absence thereof — between the die. On an AMD Threadripper or Epyc, there is 4 distinct chiplets found all around the I/O die:
The Intel CPU has no I/O die, although there’s an Altera Max 10 FPGA off-bundle. Maintaining the CPUs physically nearer together will reduce latency and cut down the energy usage put in on chiplet-to-chiplet interaction.
These are engineering samples for a CPU we really don’t expect to see for 18-24 months, so we’d consider them with a shaker of salt additional so than a grain, but what we see listed here is broadly what we’d count on to see. Intel has earlier mentioned it believes its superior packaging technology is a meaningful differentiator amongst itself and AMD. We’ll see if AMD pulls its Epyc chiplets back again alongside one another into a clustered configuration about the subsequent couple of merchandise generations, but for now it seems to be like Intel and AMD might go after various methods when it arrives to dealing with intra-chip interaction.
