New industry rumors reveal alleged details of the Intel Sapphire Rapids server processors, which will arrive with a 10nm +++ manufacturing process that seems to weigh the same 14nm +++ problem, and this translates into very poor energy efficiency, And it is said that the top-of-the-range CPU, with 56 cores, will consume 400W of energy.
This SuperFin manufacturing process will be the most advanced in the company until it can make the leap to 7nm or relegate the job to another foundry. Sapphire Rapids also puts an end to monolithic server chips from Intel, so it uses the same multichip MCM design from AMD, where we will find up to four Die’s in total where each one would offer a total of 14 cores, although there is talk that there could be 4 hidden cores, which would add up to a total of 60 cores and 120 threads instead of 56 cores and 112 threads practically confirmed.
These chips would also integrate four HBM2e memory stacks, where each stack can reach 16 GB of memory, which implies up to 64 GB of HBM2e memory of which a bandwidth of up to 1 TB / s is indicated. Additionally, it will be the first platform of the company that uses the PCI-Express 5.0 interface with up to 80 lines in the top-of-the-range CPUs and 64 in other more basic models, it will also debut the use of DDR5 @ 4800 MHz memory.
On the other hand, problems are indicated around 300 and 400W power consumption ( in the most exotic models ), reflecting that they are much higher than AMD’s (280W for 64 cores) and that they will finally face AMD GENOA CPUs with Zen4 @ 5nm, PCIe 5.0 and DDR5, which translates into serious problems for Intel when they expected their rival to be MILAN (Zen3 @ 7nm, PCIe 4.0 and DDR4) since both CPUs will arrive in 2021, or so Intel hopes, and that is that the Ice Lake-SP have been delayed a quarter, not knowing if it will affect its successor. These will offer up to 27 Sunny Cove cores @ 10nm with a TDP of 270W, so they are born dead.
