Intel Xeon W-3400 and W2400 HEDT ‘W790’ platform would be launched in Q4, 13th Gen Raptor Lake and W790 platform in October, followed by H770 and B660 in Q1 2023
A series of Intel HEDT Sapphire Rapids and Mainstream Raptor Lake-S processor rumors have been released by a reliable leaker, Enthusiastic citizen at Bilibili. Rumors detail launch dates and accompanying platforms for next-gen processor lines.
Intel HEDT Sapphire Rapids Xeon W-3400 and W-2400 processors in Q4 2022, 13th Gen Raptor Lake-S desktop processors in October 2022
We’ve known for a while now that Intel is working on its all-new desktop processor lineup for 2022, which includes both HEDT and mainstream components. The Intel HEDT family will include all-new Sapphire Rapids chips that will carry the Xeon W-3400 and Xeon W-2400 SKU branding, while the mainstream family will include 13th Gen Raptor Lake-S processors. Now, we have detailed the two families here and here, respectively.
The Intel HEDT lineup will support a W790 platform which is codenamed “Fishhawk Falls” and will support a range of chips from consumer HEDTs to high-end HEDT parts. The 13th Gen Raptor Lake desktop processors, meanwhile, will support the new 700-series board platform while remaining compatible with existing 600-series motherboards.
Intel Sapphire Rapids HEDT Desktop Processor Family
So, starting with the HEDT line, the Intel Sapphire Rapids family will include up to 24 cores for the mainstream HEDT and up to 56 cores for the premium family. All of these chips will feature a singular Golden Cove core architecture and will not benefit from hybrid P-Core/E-Core processing like mainstream desktop SKUs. You can expect the mainstream family to feature fewer DDR5 memory channels, PCIe lanes, and I/O compared to the premium family.

Intel ‘Expert’ Sapphire Rapids HEDT Processors ‘Expected Features’:
- Up to 56 cores / 112 threads
- LGA 4677 socket support (dual-socket motherboards possible)
- 112 PCIe Gen 5.0 lanes
- 8-channel DDR5 memory (up to 4TB)
Features expected from Intel’s “mainstream” HEDT Sapphire Rapids processors:
- Up to 24 cores / 48 threads
- Boost clocks up to 5.2 GHz
- Up to 4.6GHz All-Core Boost
- LGA 4677 socket support
- 64 PCIe Gen 5.0 lanes
- 4-channel DDR5 memory (up to 512 GB)
Rumor has it that Intel has delayed the launch of its Sapphire Rapids HEDT family to Q4 with a high likelihood of an October launch. Both processor segments will be supported on the new W790 powered platform.

Intel Raptor Lake Consumer Desktop Processor Family
The 13th Gen Intel Raptor Lake-S desktop processors will retain a hybrid design on the “Intel 7” process node. P-Cores will be upgraded to the new Raptor Cove architecture while E-Cores will see slight improvements in cache while Global Cores will also see an increase. The maximum number of cores was leaked as a 24-core, 32-lead part (8 P-cores + 16 E-cores). TDPs will be around the same limit as existing parts and clocks are rumored to hit 5.8GHz. Once again, cache will see a major boost.
Expected Features of 13th Generation Intel Raptor Lake Desktop Processors:
- Up to 24 cores and 32 threads
- New Raptor Cove CPU Cores (Higher P-Core IPC)
- Based on 10nm ESF ‘Intel 7’ process node
- Supported on existing LGA 1700 motherboards
- DDR5-5600 dual channel memory support
- 20 PCIe Gen 5 lanes
- Improved overclocking functions
- 125W PL1 TDP (flagship references)
Now, for the platform itself, Intel’s Raptor Lake-S desktop processors will come with support for DDR5 and DDR4 memory, giving them a major edge over the platform. AM5 only DDR5 from AMD. Another advantage for Intel is that they will have compatibility enabled on the 600 series motherboards (Z690/H670/B650 and H610) as well as the new 700 series chipsets (Z790/H770/B760). The 13th Gen Z790 and Raptor Lake desktop processors are slated to launch in October, along with the HEDT line of processors and Z790 motherboards.
The mainstream H770 and B760 chipsets will be launched by Q1 2023, but the H710 will not be produced as the H610 will be continued for low-level PC segments. The new 700 series motherboards are also rumored to support DDR4 and we may also see PCIe Gen 5.0 M.2 slots on the new line which will compete with AMD’s own AM5 platform which has Gen 5 for M.2 and dGPU.
