Intel: Big changes on the next server processors: Sapphire rapids

While Ice Lake SP will only arrive in the first quarter of 2021, Sapphire Rapids, its successor, is already unveiling its main characteristics in a leaky site adoredtv.

Sapphire Rapids: 56 hearts by the end of 2021


Badly mauled by AMD and ARM, Intel is losing more and more market share in the server sector. This situation should hardly improve with the next Ice Lake SPs, postponed for the first quarter of 2021, which should offer up to 38 cores, all engraved in 10nm+(not SuperFin).

But the blues could come back in the race with their next generation of processors named : Sapphire rapids. Scheduled for the end of 2021 or even early 2022, this generation should bring major changes to better compete with the AMD Milan and Genoa.

Sapphire Rapids (or SPR), etched in 10nm Enhanced SuperFin (10nm++), will use the Golden Cove architecture, allowing it to take advantage of high frequencies and a consequent IPC gain compared to Ice Lake. The largest version is expected to offer up to 56 cores distributed over 4 chiplets of 14 cores with a TDP of up to 400W. This should be on the 4677 LGA socket, with support for 4800Mhz DDR5, PCIE 5.0 ( up to 80 lines ) and Optane memory support.

SPR ‘s major novelty would come from its MCM (Multi-Chip Module) design. As previously mentioned, the processor would consist of 4 chiplets for the cores, as well as 4 chiplets of HBM2e memory, amounting to 64 GB with 1 TB/s of bandwidth, which can work in conjunction with DDR5 depending on the modes used.

This generation would therefore herald major upheavals compared to Cooper Lake and Ice Lake SP. It will have to compete with the next AMD Milan (Zen 3), whose initial benchmarks are very encouraging, and undoubtedly Genoa (Zen 4). In short, there is only good news in the competition.
