The Intel 15900K/Core Ultra 9 285K is set to offer 20 PCIe 5 lanes, in contrast to the 24 present on the AMD Ryzen 9 9950X.

Leaked information from Chiphell has disclosed the I/O capabilities of Intel’s Arrow Lake-S processors, slated for release in the final quarter of 2024. These processors will introduce the LGA1851 socket, transitioning away from the previous LGA1700 in conjunction with the 800-series chipset lineup, which includes Z890, B860, H870, and H810 motherboards.

According to leaked details, the Arrow Lake-S processors from Intel will boast 20 usable PCIe Gen 5 lanes, with 16 dedicated to discrete graphics and four for M.2 NVMe SSDs. Additionally, there will be a separate 4-lane PCI Gen 4 cluster for M.2 storage and two Thunderbolt 4 ports.

Comparatively, AMD’s Ryzen 9000 CPUs are expected to feature 24 PCIe Gen 5 lanes. Despite this, Intel has an edge in memory speeds, with Arrow Lake chips potentially supporting up to 6400 MT/s compared to Ryzen’s 6000 MT/s.

Intel’s 800-series chipsets will comprise up to 24 PCIe Gen 4 lanes, alongside 8 SATA III lanes, and 3 GbE ports. USB connectivity will include options for 10 USB 3.2 Gen2 x1 (or 5 USB 3.2 Gen 2×2), 14 USB 2, and a BT6/WiFi7 adapter configuration. On the flip side, AMD’s 800-series chipset offerings will vary across different models.

There has also been speculation surrounding the core layout of Arrow Lake processors, with a proposed design showcasing E-cores interspersed between columns of P-cores. This contrasts with previous iterations where P and E-core clusters were distinctly separated. The reasoning behind this new design remains ambiguous, hinting at potential inter-core latency or bandwidth optimizations.
