Intel Xeon W-3400 & W2400 HEDT ‘W790’ platform rumored to launch in Q4, 13th generation W790 platform in October, followed by H770 and B660 in Q1 2023

A series of rumors regarding Intel HEDT Sapphire Rapids & Mainstream Raptor Lake-S CPUs have been spread by a trusted leaker, Enthusiast Citizen of Bilibili. Rumors reveal the launch dates and accompanying systems for the next generation of CPU sets.

Intel HEDT Sapphire Rapids Xeon W-3400 & W-2400 CPUs in Q4 2022, 13th Generation Raptor Lake-S Desktop CPUs in October 2022

We’ve known for some time that Intel is working on a new desktop CPU lineup for 2022 that includes both HEDT and mainstream parts. The Intel HEDT family will consist of all-new Sapphire Rapids chips that will be named the Xeon W-3400 & Xeon W-2400 series, while the dominant family will consist of the 13th generation Raptor Lake-S processors. Now we’ve detailed both families here and here respectively.

The Intel HEDT suite will feature support on the W790 platform codenamed “Fishhawk Falls” and will support a range of chips ranging from mainstream HEDT to premium HEDT parts. The 13th-generation Raptor Lake desktop CPUs, on the other hand, will feature support on the new 700-series motherboard platform while remaining compatible with existing 600-series motherboards.

Intel Sapphire Rapids HEDT Desktop CPU Family

So starting with the HEDT family, the Intel Sapphire Rapids family will consist of up to 24 cores for the mainstream HEDT and up to 56 cores for the premium family. All of these chips will feature a unique Golden Cove core architecture and won’t get the hybrid P-Core/E-Core processing like mainstream desktop SKUs do. You can expect the mainstream family to feature fewer DDR5 memory channels, PCIe lanes, and IO lanes than the premium family.

Intel ‘Expert’ Sapphire Rapids HEDT CPUs ‘Expected Features’:

  • Up to 56 cores / 112 threads
  • LGA 4677 socket support (dual socket motherboards)
  • 112 PCIe Gen 5.0 Lanes
  • 8-channel DDR5 memory (up to 4TB)

Intel “Mainstream” Sapphire Rapids HEDT CPUs “Expected Features”:

AMD will stream EPYC CPUs with Xilinx-based FPGA AI drives, starting in 2023

  • Up to 24 cores / 48 threads
  • Up to 5.2GHz Boost Hours
  • Up to 4.6 GHz All-Core Boost
  • LGA 4677 . socket support
  • 64 PCIe Gen 5.0 slots
  • 4-Channel DDR5 Memory (up to 512GB)

Rumors have it that Intel has postponed the launch of the Sapphire Rapids HEDT family to the fourth quarter with a high probability of an October launch. Both CPU sections will offer support on the new platform running the W790.

Intel Raptor Lake Desktop CPU Family

The 13th generation Intel Raptor Lake-S desktop CPUs will retain a hybrid design on an “Intel 7” processing node. P-Cores will be upgraded to the new Raptor Cove architecture while E-Cores will have minor cache improvements while overall cores will also see an increase. The maximum number of nuclei was leaked as 24 cores and 32 thread segments (8 cores + 16 electronic cores). TDPs will be around the same as the max on existing parts and clocks and are expected to reach 5.8GHz according to the rumor maker. Once again, your cache will experience a huge boost.

Expected Features of 13th Generation Intel Raptor Lake Desktop CPUs:

  • Up to 24 cores and 32 threads
  • Brand New Raptor Cove CPU Cores (Top P-Core IPC)
  • Based on 10nm ESF ‘Intel 7’ processing node
  • Supported on current LGA 1700 motherboards
  • Dual channel DDR5-5600 memory support
  • 20 PCIe Gen 5 slots
  • Enhanced overclocking features
  • 125W PL1 TDP (Master SKUs)

Now for the platform itself, Intel’s Raptor Lake-S desktop CPUs will come with support for DDR5 and DDR4 memory, giving it a significant advantage over AMD’s AM5 DDR5-only platform. Another advantage of Intel is that compatibility will be enabled on both 600 series motherboards (Z690/H670/B650 and H610) along with the new 700 series chipsets (Z790/H770/B760). The Z790 and 13th Gen Raptor Lake Desktop processors are expected to launch in October, along with the HEDT CPU lineup with Z790 motherboards.

The mainstream H770 and B760 chipsets will be released by the first quarter of 2023 but the H710 will not be produced as the H610 will be ported to lower-end PC chips. New 700 series motherboards are also rumored to feature DDR4 support and we can also see PCIe Gen 5.0 M.2 slots in the new lineup which will compete with AMD’s AM5 platform which has Gen 5 for M.2 and dGPU.
