A recent leak has revealed the block diagram of the upcoming Intel Arrow Lake-S “800 series” desktop CPU platform, showcasing dedicated Gen5 lanes. The Arrow Lake-S desktop CPUs will be supported by the 800 series platform and will feature up to 20 dedicated PCIe Gen5 lanes. The leak, originally shared on the Chiphell Forums, provides insights into the platform’s details and configurations.
Intel’s 800 series platform will introduce the Arrow Lake-S desktop CPUs on new LGA 1851-socket motherboards. These motherboards, including the Z890, H870, B860, and H810 series, will support higher-end features such as DDR5-6400 memory. The platform diagram also reveals two additional SKUs with 6+8 and 6+16 configurations for varying core counts.
The new Intel 800 series platform will support higher memory speeds natively, with DDR5 UDIMM/SODIMM at up to 6400 MT/s in a dual-channel configuration. The CPUs will offer native x16 PCIe Gen5 dGPUs and x4 PCIe Gen5 M.2 lanes, along with additional x4 PCIe Gen4 lanes for M.2. The Arrow Lake-S CPU will have 20 PCIe Gen5 lanes and 8 SATA III lanes, while the ARL-S PCH for 800 series motherboards will feature DMI Gen4, PCIe Gen4 lanes, SATA III lanes, USB ports, and other connectivity options.
In comparison to AMD’s Ryzen 9000 desktop CPUs, Intel’s Arrow Lake CPUs will have slightly fewer usable PCIe Gen5 lanes, with 20 lanes compared to AMD’s 24 lanes. Additionally, Arrow Lake CPUs will feature native DDR5-6400 support, while Zen 5 CPUs will have native support for DDR5-5600.
The upcoming Arrow Lake-S desktop CPUs are anticipated to launch in the second half of 2024 and will compete with AMD’s Zen 5-based Ryzen 9000 “Granite Ridge” CPUs. These new CPUs will mark Intel’s entry into the next-generation LGA 1851 socket and 800 series motherboards, offering various enhancements such as increased PCIe Gen 5.0 lanes and updated integrated graphics.
During Computex 2024, Intel’s motherboard partners showcased their next-generation designs based on the Z890 PCH and LGA 1851 socket, preparing for the upcoming launch of Arrow Lake-S CPUs. The comparison table provided in the article outlines the various Intel desktop CPU generations, highlighting the evolution of processor architectures, platform chipsets, memory support, and other key specifications.
In conclusion, the leaked details of Intel’s Arrow Lake-S desktop CPU platform indicate significant advancements in performance and features, setting the stage for a competitive launch later in 2024. Fans of desktop computing can look forward to the arrival of Arrow Lake-S CPUs and the associated 800 series motherboards, which promise enhanced capabilities and improved user experiences.
