Entry Server / Workstation
The Intel Xeon 6357P is an 8-core, 16-thread entry-server and workstation processor based on the Raptor Lake Refresh architecture, built on Intel 7 process, with a 3.0 GHz base and 5.4 GHz turbo, 24 MB L3 cache, 80 W TDP, DDR5-4800 support, and 20 PCIe 5.0 lanes on FCLGA1700.
Intel Xeon 6357P sits in the Xeon 6300P entry-server family, offering 8 Performance-cores, 16 threads, 3.0 GHz base and 5.4 GHz turbo, 24 MB L3, and 80 W TDP.
It supports dual-channel DDR5-4800 ECC memory and 20 PCIe 5.0 lanes on FCLGA1700, making it a straightforward upgrade from older Xeon E-2400 or E-2300 platforms for small business servers, virtualization, and light infrastructure workloads. It lacks the core count and memory bandwidth of larger Xeon 6 or EPYC parts, but for 1P systems that value frequency and modern I/O, it is a balanced choice.
Specifications
Performance
Strong single-thread and competent multi-thread performance for entry-server and light workstation tasks, though heavier multi-threaded workloads may prefer more cores.
Good for modest VM counts per host; memory bandwidth and core count limit large-scale consolidation.
Not targeted at gaming, but its high clocks deliver reasonable frame rates in CPU-limited titles; GPU and platform choices matter more.
80 W TDP is efficient for its performance, but higher-clocked, fewer-core designs can be more performance-per-watt in some workloads.
- •High P-core clocks benefit CPU-bound games.
- •Not optimized for high-refresh-rate gaming; no integrated graphics.
- •Best paired with a discrete GPU and used where server functionality is primary.
- •No dedicated AI matrix engine like AMX.
- •AVX2 and VNNI provide some acceleration for CPU-based inference.
- •Suitable for small models and prototyping, not for large-scale training.

Architecture Overview
Xeon 6357P uses the Raptor Lake Refresh silicon configured as a performance-core-only, server-validated part on the Intel 7 process, focusing on high clocks and modern I/O rather than large core counts.
CPU Design
8 Performance-cores with Hyper-Threading yield 16 threads. Each P-core has high out-of-order resources and deep buffers, optimized for frequency and IPC rather than density.
Memory Subsystem
Integrated dual-channel DDR5 memory controller at 4800 MT/s with ECC support, providing more bandwidth than DDR4-based Xeon E-2300/E-2400 platforms, but still half the channels of larger Xeon Scalable CPUs.
PCIe & I/O
20 PCIe 5.0 lanes from the CPU, typically configured as 1x16 + 1x4 or 2x8 + 1x4, plus additional PCIe from the C260-series chipset. This is a significant upgrade over PCIe 4.0 on previous-gen entry Xeons.
Overclocking
Multiplier is locked; no enthusiast overclocking. Turbo behavior is managed by Intel Turbo Boost 2.0 and Turbo Boost Max 3.0, with power and thermal constraints defining sustained frequencies.
- PCIe 5.0 vs PCIe 4.0
- DDR5-4800 vs DDR4-3200
- Higher single-core turbo (5.4 GHz vs 5.2 GHz)

- Dual-channel memory limits bandwidth for HPC or large VMs
- 1S-only, no multi-socket scaling
- No integrated graphics
- Locked multiplier, no overclocking
History
The Intel Xeon 6357P emerged as part of the Xeon 6300P series in early 2025, filling the entry-server niche between the older Xeon E-2400 line and higher-end Xeon Scalable platforms. It leverages the same Raptor Lake Refresh silicon used in 13th/14th Gen Core desktop CPUs, but with server-focused validation, ECC memory support, and enterprise security features like Intel TDX and Total Memory Encryption. Compared to its Xeon E-2478 predecessor, the 6357P shifts the platform from DDR4 and PCIe 4.
0 to DDR5-4800 and PCIe 5.0, while keeping a similar 8-core, 80 W envelope. OEMs such as Dell and Lenovo adopted the 6357P in small business tower servers and entry-level rack systems, emphasizing its balance of frequency, I/O, and power efficiency for lightweight infrastructure and edge workloads.
Improvements over Previous Generation

Interesting Facts
Xeon 6357P is part of Intel’s Xeon 6300P series, which refreshes the Xeon E-2400 line with Raptor Lake cores and PCIe 5.0.
Despite being a server part, it shares its silicon with 13th/14th Gen Core ‘Raptor Lake’ desktop CPUs, but validated for enterprise use cases.
Its 80 W TDP matches many mainstream desktop CPUs while offering enterprise features like ECC and TDX.
PassMark lists a CPU Mark around 30,401 and single-thread around 4,168, placing it in the upper range of entry-server CPUs.
Intel markets the Xeon 6300P series specifically for entry servers, positioning it between Xeon E and Xeon Scalable.
