Architecture Overview
The Xeon 6315P is part of Intel’s Xeon 6300 series, which rebrands and refreshes the Xeon E-2400 Raptor Lake-E lineup into the Xeon 6 family. It uses the same Raptor Lake silicon as 14th-gen Core processors, but configured for server use with ECC, RAS, and virtualization features. The chip is a P-core-only design with four high-performance Raptor Cove cores, no E-cores, and no Hyper-Threading, keeping the implementation simple and power-efficient for entry servers.
CPU Design
Four Raptor Cove performance cores, each with 1.25 MB of L2 cache, sharing a 12 MB L3 cache. The cores support Intel AVX2 and Intel SSE4.1/4.2, but not AVX-512. Without Hyper-Threading, each physical core handles one hardware thread, which simplifies scheduling and reduces vulnerability side-channel exposure in some workloads.
Memory Subsystem
An integrated dual-channel DDR5 memory controller supports DDR5-4800 with ECC at up to 128 GB. This is a step up from Xeon E-2300’s DDR4-3200, providing higher bandwidth and better capacity per channel, though still only two channels. The memory controller is tuned for server-typical access patterns and supports Intel Total Memory Encryption and multi-key TME for improved security.
PCIe & I/O
The CPU provides 20 PCIe 5.0 lanes, configurable as 1x16+1x4 or 2x8+1x4, plus an 8-lane DMI 4.0 link to the Intel C260-series chipset. This allows direct attachment of high-speed NVMe SSDs, 25/40/100GbE NICs, and accelerators with full PCIe 5.0 bandwidth, while the chipset adds additional I/O such as SATA, USB, and lower-speed networking.
Overclocking
The multiplier is locked, and the processor is intended for fixed-frequency server platforms. Some OEM firmwares may allow limited power or turbo tuning, but this is not an enthusiast overclocking target.

History
The Xeon 6315P emerged as part of Intel’s effort to unify its entry-level server lineup under the Xeon 6 brand. For years, the Xeon E-2300 series (Rocket Lake-E) and then Xeon E-2400 (Raptor Lake-E) served the single-socket server market, but they sat outside the main Xeon Scalable family. With the Xeon 6300 series, Intel rebranded these Raptor Lake-E parts as Xeon 6, aligning them more closely with Xeon 6700 and 6900 in naming, even if the underlying silicon and core counts remained modest.
</br></br>Compared to Xeon E-2300, the Xeon 6300 generation brought DDR5 support and PCIe 5.0 to the entry segment, responding to AMD’s pressure in the low-end server space where EPYC Embedded and older Xeon D platforms offered competitive features. Intel’s own positioning treats Xeon 6300 as the low rung of the Xeon 6 ladder, focusing on essential performance and reliability for small business servers rather than the high-core-count, dual-socket designs of Xeon 6700/6900.
</br></br>Analysts and reviewers have noted that Xeon 6300 is more of a rebrand than a radical architectural shift, with some criticism that core counts top out at 8 in this generation while AMD pushes higher core counts at similar power. For the Xeon 6315P specifically, that means a 4-core design that is competitive on I/O and efficiency but not on raw throughput. It is nonetheless significant as one of the first mainstream entry-server CPUs to bring PCIe 5.
0 and DDR5 to low-power single-socket platforms, setting a baseline for future Raptor Lake-E and Granite Rapids-based successors.

Interesting Facts
The Xeon 6300 series is essentially a rebrand and refresh of the Xeon E-2400 Raptor Lake-E lineup under the Xeon 6 umbrella.
Despite the Xeon 6 branding, the 6315P still uses only P-cores and tops out at 4 cores, like earlier Xeon E-2300 parts.
Intel’s own ARK lists a max turbo of 4.7 GHz for 6315P, but many OEMs and retailers consistently advertise 5.2 GHz, possibly reflecting platform-specific turbo or all-core behavior.
SPEC CPU2017 results for Xeon 6315P show 1.25 MB L2 per core and 12 MB L3, confirming it shares the Raptor Lake client cache hierarchy adapted for server use.
The Xeon 6300 series is designed to pair with Intel C260-series chipsets (e.g., C262), which provide additional SATA, USB, and networking I/O alongside the CPU’s PCIe 5.0 lanes.
Compared to Xeon E-2314/E-2414, the 6315P offers DDR5 and PCIe 5.0 while staying at similar or lower TDP, improving performance per watt.
The 6315P’s single-socket, 55 W profile makes it a popular choice for micro servers and tower appliances like HPE’s ProLiant MicroServer Gen11.
Unlike some Xeon Scalable processors, there is no Hyper-Threading, which reduces speculative-execution attack surface but also limits concurrent threads per core.
The processor supports Intel Total Memory Encryption and multi-key TME, which is relatively rare in this segment and valuable for security-sensitive edge deployments.
Intel positions Xeon 6300 as the low end of the Xeon 6 family, above Atom but below Xeon 6700/6900, creating a clear but sometimes confusing segmentation between Xeon E and Xeon 6.
