Intel’s Subsequent-Gen Xeon CPU Leaks: 4-Method Sapphire Rapids In Q1 23, 8-Method In Q3 23, Granite Rapids & Diamond Rapids With HBM Choices
On: October 13, 2022
New data on Intel’s next-gen Sapphire Rapids, Granite Rapids, and Diamond Rapids Xeon CPUs has been leaked out.
Intel’s Full Sapphire Rapids-SP Xeon CPU Lineup Leaks Out, Early Granite Rapids & Diamond Rapids Platform Info Revealed
Intel has formally revealed 4 next-gen Xeon CPU platforms that may launch within the coming years. These embrace Sapphire Rapids, Emerald Rapids, Granite Rapids, and Diamond Rapids. We have already got numerous data coated for the Sapphire Rapids platform and the lineup itself but it surely seems like Intel has prepped up much more SKUs than what we had coated earlier as reported by YuuKi AnS.

Intel Sapphire Rapids-SP Xeon CPU Platform
The Sapphire Rapids lineup will make use of 8-channel DDR5 reminiscence with speeds of as much as 4800 Mbps & assist PCIe Gen 5.0 on the Eagle Stream platform (C740 chipset). The lineup tops out at 60 cores which is the flagship die configuration with 15 cores enabled on every of the 4 chiplet dies.
The Eagle Stream platform may even introduce the LGA 4677 socket which will probably be changing the LGA 4189 socket for Intel’s upcoming Cedar Island & Whitley platform which might home Cooper Lake-SP and Ice Lake-SP processors, respectively. The Intel Sapphire Rapids-SP Xeon CPUs may even include CXL 1.1 interconnect that may mark an enormous milestone for the blue workforce within the server section.

Coming to the configurations, the highest half is began to function 60 cores with a TDP of 350W. What’s fascinating about this configuration is that it’s listed as a low-bin break up variant which signifies that it will likely be utilizing a tile or MCM design. The Sapphire Rapids-SP Xeon CPU will probably be composed of a 4-tile format with every tile that includes 14 cores. The Intel Sapphire Rapids-SP Xeon CPUs will are available 4 tiers:
Bronze Tier: 150W TDP
Silver Tier: 145-165W TDP
Gold Tier: 150-270W TDP
Platinum Tier: 250-350W+ TDP
Moreover, every tier will probably be featured in particular segments which embrace:
The TDPs listed below are at PL1 score so the PL2 score, as seen earlier, goes to be very excessive within the 400W+ vary and the BIOS restrict is anticipated to hover at round 700W+. In comparison with the final itemizing where a lot of the SKUs had been nonetheless within the ES1/ES2 state, the brand new specs are based mostly on ultimate chips which will probably be hitting retail.
The flagship of the lineup is the Intel Xeon Platinum 8490H which provides 60 Golden Cove cores, 120 threads, 112.5 MB of L3 cache, 2.9 GHz all-core increase clocks, and a base TDP determine of 350W. That is optimized for as much as 8 socket configurations for a complete of 480 cores and 960 threads.

Intel Granite Rapids-SP sixth Gen Xeon CPU Household
Moving over to Granite Rapids-SP, that is where Intel actually begins to make some huge modifications to its lineup. As of straight away, Intel has confirmed that its Granite Rapids-SP Xeon CPUs will probably be based mostly on the ‘Intel 4’ course of node (Formely 7nm EUV). The lineup is anticipated to launch someday between 2023 and 2024 as Emerald Rapids will probably be serving as an middleman resolution & not a correct Xeon household alternative.
It’s said that Granite Rapids-SP Xeon chips will make the most of the Redwood Cove core structure and have elevated core counts although the precise quantity just isn’t supplied. Intel did tease a high-level overview of its Granite Rapids-SP CPU throughout its ‘Accelerated’ keynote which appeared to function a number of dies packaged in a single SOC by way of EMIB. We are able to see HBM packages together with high-bandwidth Rambo Cache packages. The Compute tile appears to be composed of 60 cores per die which equals 120 cores in complete however we should always count on a couple of of these cores to be disabled to get higher yields on the brand new Intel 4 course of node.
So we really feel very snug with that. We’re then working very intently — emerald goes into the Sapphire platform. So we’re working very intently with our prospects on the timing there. The product is wanting very wholesome.
So we’re properly on observe. In order that will probably be a ’23 product. After which Granite and Sierra Forest is the ’24 product. And simply to remind everyone, it is a main new platform.

AMD will probably be growing the core counts of its personal Zen 4C EPYC lineup with Bergamo, pushing out as much as 128 cores and 256 threads so, regardless of Intel doubling its core rely, they nonetheless won’t be capable of match AMD’s disruptive multi-threaded and multi-core lead. However by way of IPC, that is where Intel may begin getting near AMD’s Zen structure within the server section and again within the game. Whereas earlier rumors had talked about 12-channel DDR5 & PCIe 6.0 assist, the newest data states that the chips will are available HBM choices and assist 8-channel DDR5, PCIe 5.0, CXL 2.0, and PFR 4.0.
Intel Diamond Rapids-SP seventh Gen Xeon CPU Household
Come Diamond Rapids-SP and Intel may lastly have their huge win in opposition to AMD since its first EPYC launch again in 2017. Diamond Rapids Xeon CPUs are anticipated to launch by 2025 with a radically new structure that will probably be positioned in opposition to Zen 5. The EPYC Turin lineup based mostly on Zen 5 will not be coming slowly as AMD will concentrate on Intel planning a comeback within the knowledge heart and server section. Thus far, there are not any particulars out there as to what structure or core rely the brand new chips will provide however they’ll provide compatibility on the identical Birch Stream & Mountain Stream platforms that may even assist Granite Rapids-SP chips.
The Diamond Rapids seventh Gen Xeon CPUs are anticipated to function the improved Lion Cove cores on the Intel 3 (5nm) course of node and provide as much as 144 cores and 288 threads. For the platform itself, the chips are anticipated to supply as much as 128 PCIe Gen 6.0 lanes, 8-channel DDR5 assist, CXL Gen 3.0, and with none onboard PCH.
