Workstation
The Intel Xeon w5-2545 is a 12-core, 24-thread workstation processor built on the Sapphire Rapids Refresh design. It pairs 64 PCIe 5.0 lanes and quad‑channel DDR5‑4800 support with up to 2 TB memory, targeting professional workloads such as 3D rendering, simulation, software development, and local AI inference in single‑socket workstations.
The Intel Xeon w5‑2545 sits in Intel’s W‑2500 mainstream workstation stack, offering 12 performance cores and 24 threads with a 3.5 GHz base and 4.7 GHz all‑core turbo.
It uses the LGA4677 socket, provides 64 PCIe 5.0 lanes from the CPU, and supports up to 2 TB of quad‑channel DDR5‑4800 ECC memory. The 210 W base power and 252 W maximum turbo power make it a power‑hungry part suited to OEM towers like Dell’s Precision 5860.
Intel’s AMX and AVX‑512 accelerate AI and vector workloads, while vPro Enterprise and ECC/RAS features add enterprise reliability. It is not a gaming part and has no integrated graphics, but for professionals running CAD, rendering, virtualization, and local AI workloads, it offers a solid mix of cores, clocks, and platform I/O.
Specifications
Performance
Strong multi‑threaded performance for CPU‑bound applications like rendering, encoding, and simulation. Twelve P‑cores and high boost clocks help with interactive work.
Excellent for hosting multiple VMs thanks to 12 cores/24 threads, PCIe 5.0 for fast networking and storage, and Intel VT‑x/VT‑d/EPT support.
The w5‑2545 can game fine when paired with a strong GPU, but its value is in workstation workloads, not gaming. Clocks are lower than mainstream gaming CPUs and there is no integrated graphics.
At 210 W base and up to 252 W turbo, the chip draws significantly more power than mainstream desktops; it is best in well‑ventilated OEM towers with robust cooling.
- •Sufficient per‑core performance for 60+ fps at 1080p in many titles when paired with a strong GPU.
- •Higher power draw and platform cost compared with mainstream gaming CPUs.
- •No integrated graphics; a discrete GPU is mandatory.
- •Optimized gaming workloads are not the primary target for this workstation platform.
- •Intel AMX improves AI inference performance via dedicated tile‑matrix operations.
- •AVX‑512 with Bfloat16 support (3rd Gen DL Boost) benefits frameworks that can use it.
- •Best suited to inference and small‑scale training; for larger workloads, dedicated GPUs are still faster.

Architecture Overview
Sapphire Rapids is Intel’s server‑and‑workstation microarchitecture, built on Intel 7 (10 nm‑class) with big performance and efficiency improvements over prior generations. The Xeon W‑2500 refresh brings more cores and higher clocks to the mainstream workstation stack while keeping the same LGA4677 socket and platform features.
CPU Design
The w5‑2545 uses 12 performance cores with Hyper‑Threading (24 threads) and no efficient cores. Intel configures two AVX‑512 FMA units per core, which helps vectorized workloads and AI primitives. The chip supports Intel Turbo Boost Technology 2.0 (4.5 GHz) and Turbo Boost Max 3.0 (4.7 GHz).
Memory Subsystem
Quad‑channel DDR5‑4800 with ECC is supported. The official maximum memory size is 2 TB, which is substantial for memory‑intensive simulations and large datasets. Intel does not support Optane Persistent Memory on this part.
PCIe & I/O
The CPU directly provides 64 PCIe 5.0 lanes, enough for multiple GPUs, NVMe SSDs, and high‑speed networking without sharing chipset bandwidth. The DMI 4.0 link to the chipset handles additional I/O.
Overclocking
The w5‑2545 is not in Intel’s official unlocked list; only select W‑2500 and W‑3500 SKUs ending in X are unlocked. Expect limited or no multiplier control, though base‑clock or BCLK may be adjustable depending on the motherboard.
- Higher base clock (3.5 GHz vs 3.2 GHz on w5‑2455X).
- Slightly improved turbo behavior and newer stepping.
- Updated platform support and better AMX/accelerator enablement.
- Refreshed price positioning within the W‑2500 stack.
Key Highlights
- 12 performance cores with Hyper‑Threading and up to 4.7 GHz turbo for strong multi‑threaded performance.
- 64 PCIe 5.0 lanes enable multiple high‑speed devices without sharing bandwidth.
- Quad‑channel DDR5‑4800 ECC support with up to 2 TB capacity for large workloads.
- Intel AMX, AVX‑512, and DL Boost accelerate AI and scientific computing.
- Intel vPro Enterprise and RAS features for enterprise manageability and reliability.
- Data Streaming Accelerator (DSA) offloads common data‑movement operations.
- No integrated graphics; a discrete GPU is required.
- Not an unlocked SKU (w5‑2545 is locked); limited overclocking.
- Base power of 210 W and turbo power of 252 W require robust cooling and a spacious chassis.
- Memory speed limited to DDR5‑4800; faster kits will downclock unless overclocked on unlocked SKUs.
- Platform cost is higher than mainstream desktop; best suited to OEM workstations.
History
Intel announced the Xeon W‑3500 and W‑2500 families on August 28, 2024, describing them as a refresh of the Sapphire Rapids workstation lineup aimed at creators, engineers, and AI developers. The W‑2500 stack added cores and modestly improved frequencies over the prior W‑2400 generation, while keeping the LGA4677 socket and expanding support for DDR5, PCIe 5.0, and AI accelerators like AMX.
The w5‑2545 emerged as the mid‑range 12‑core SKU, positioned below the 14‑core w5‑2555X and the higher‑core W7 models. OEMs such as Dell quickly adopted it in systems like the Precision 5860 Tower, reflecting Intel’s strategy to push Sapphire Rapids Refresh into single‑socket workstations where local AI and large datasets are increasingly common.
Improvements over Previous Generation
- Higher base clock (3.5 GHz vs 3.2 GHz on w5‑2455X).
- Slightly improved turbo behavior and newer stepping.
- Updated platform support and better AMX/accelerator enablement.
- Refreshed price positioning within the W‑2500 stack.
