{Hardware} leaker YuuKi_AnS (opens in new tab) has offered a sneak peek of what we might anticipate from Intel’s next-generation Xeon Emerald Rapids processors. It’s humorous as a result of Sapphire Rapids (opens in new tab) hasn’t landed, however the specs of its successor are already hitting the rumor mill. Though the leaker claims that the specs got here from a doc allegedly distributed to OEMs lately, we advocate you method the knowledge with an open thoughts.
Like Sapphire Rapids, Emerald Rapids proceed to depend on the Intel 7 (rebranded 10nm Enhanced SuperFin) course of node. The forthcoming knowledge heart chips will slip into the identical Eagle Stream platform with the LGA4677 (Socket E) socket as Sapphire Rapids. Intel hasn’t confirmed which microarchitecture will energy Emerald Rapids, although. Sapphire Rapids will include Golden Cove cores; subsequently, Emerald Rapids would most likely wield Raptor Cove cores.
Whereas Sapphire Rapids have appeared to high out at 56 cores, Emerald Rapids might push it as much as 64 cores to match AMD’s EPYC processors. The issue is that Emerald Rapids could have very robust competitors. AMD’s Genoa rocks as much as 96 cores, whereas Bergamo (opens in new tab), which launches in 2023, could have as much as 128 cores. Intel continues to be behind AMD by way of core counts.
Emerald Rapids’ TDP could differ between 150W and 350W with wonderful scalability. The processor help 1S, 2S, 4S, 8S, and better configurations by way of xNC help. 4 UPI 2.0 hyperlinks per Emerald Rapids processor at the next width (x24) supply switch speeds as much as 20 GT/s.
Eight-channel reminiscence stays a function on Emerald Rapids; nonetheless there’s improved reminiscence pace help. The processors natively help DDR5-5600 in a 1DPC setup and DDR5-4800 in a 2DPC configuration. The Eagle Stream platform will allow as much as 16 DDR5 reminiscence slots per socket. The specification sheet mentions help for 24Gb reminiscence modules. Emerald Rapids additionally embraces Intel’s Crow Move Persistent Reminiscence (Crystal Ridge 3.0) modules. Though Intel has canned its Optane reminiscence enterprise, Crow Move will nonetheless make it to the market. Nevertheless, the chipmaker will not develop any future Optane merchandise past Crow Move.
By way of growth, Emerald Rapids ship as much as 80 PCIe 5.0 lanes. The platform supplies PCIe bifurcation help at x16, x8, x4, and x2 by way of PCIe 4.0 speeds. The Emmitsburg chipset, alternatively, provides 20 PCIe 3.0 lanes, 1G Ethernet for Manageability help, and an x8 DMI connection restricted to the PCIe 3.0 commonplace. AMD hasn’t share the variety of PCIe 5.0 lanes for Genoa or Bergamo. For distinction, AMD EPYC chips have been providing 128 PCIe lanes for a few generations now.
Not like Sapphire Rapids, Intel is assured that Emerald Rapids will meet its 2023 deadline.
