Intel’s 15th Gen Arrow Lake-S CPU introduces: 24 Cores, No Hyper-Threading, and 125W TDP

Intel has launched the specifications of its highly anticipated 15th Gen Arrow Lake processors, along with details about the accompanying PCH (Platform Controller Hub). While much has already been revealed about the CPU architecture, the PCH has remained a mystery until now. Let’s dive into the exciting features of Intel’s latest offering.

Starting with the Arrow Lake-S CPU, it boasts an impressive 24 cores, comprising 8 performance cores (P-Cores) and 16 efficiency cores (E-Cores). However, it’s worth noting that this information is based on a pre-alpha sample, and hyper-threading seems to have been disabled from the BIOS. This means that the thread count is limited to 24. Intel has also made an interesting shift from hyper-threading to Rentable Units with the Arrow Lake processors.

In terms of power consumption, the Arrow Lake-S CPU has a base TDP (Thermal Design Power) of 125W. The listed clock speed is 3.5GHz, which could either be the base clock for the P-cores or the boost clock for the E-cores. It’s important to remember that these frequencies are likely to be lower in the final market version.

The P-cores, codenamed “Lion Cove,” are expected to feature 3MB of L2 cache, which is a significant improvement compared to the previous Raptor Lake processors’ 2MB cache. Additionally, Intel claims that these processors will offer a 15% improvement in multi-threaded performance over their predecessors, thanks to the combination of Lion Cove P-cores and Skymont E-cores.

The Arrow Lake-S family will debut alongside the LGA1851 socket, and it will be accompanied by the Z890 chipset. This chipset hints at the existence of two more dies with 14 cores (6P + 8E) and 22 cores (6P + 16E). The CPUs will natively support DDR5-6400 memory, a significant upgrade from DDR5-5600. They will also offer 20 PCIe Gen 5 lanes for dGPU and M.2 NVMe, along with four Gen 4 lanes for an M.2 SSD. Additionally, users can expect up to 8 SATA III lanes, two USB 4.0 ports, and one Thunderbolt 4 port.

Turning our attention to the PCH, it features a DMI3 x8 (Gen 4) interconnect to the CPU, 24 PCIe Gen 4 lanes, 8 SATA III ports, 10 USB 3.2 Gen 2×1 ports, Bluetooth 6/WiFi 7 support, and 14 USB 2.0 ports. These specifications ensure seamless connectivity and high-speed data transfer capabilities.

Intel plans to launch its 15th Gen Arrow Lake processors in the second half of this year. These processors will be the first to utilize the Intel 20A node, which incorporates RibbonFET (GAA) and backside power delivery technologies. The combination of these advancements promises improved performance and efficiency for users.

As we eagerly await the release of Intel’s Arrow Lake processors, it’s clear that the company is pushing the boundaries of CPU technology. With increased core counts, enhanced cache sizes, and support for faster memory and connectivity options, these processors are poised to deliver impressive performance gains. Stay tuned for more updates on Intel’s exciting new products.
