The Intel Xeon w7-2575X is a 22-core, 44-thread workstation processor based on the Sapphire Rapids architecture, built on Intel 7 and designed for single-socket workstations with quad-channel DDR5-4800, 64 PCIe 5.0 lanes, and a 250W base power rating.
Intel’s Xeon w7-2575X combines 22 performance cores, 44 threads, a 3.0 GHz base and 4.8 GHz turbo, 45 MB of Smart Cache, quad-channel DDR5-4800 with ECC, and 64 PCIe 5.
0 lanes in a single-socket LGA-4677 package. It is aimed at workstations for 3D rendering, simulation, video editing and AI workloads, offering strong multi-threaded performance and I/O, but at 250W base and 300W max turbo it demands robust cooling and a substantial platform investment.
Specifications
Performance
Strong multi-threaded performance for professional content creation and engineering workloads, especially when heavily parallelized.
Excellent for single-socket VM hosts with many vCPUs, though some workloads may still benefit from dual-socket platforms.
Capable of high-refresh-rate gaming at 1440p with a modern GPU, but not optimized for gaming; mainstream desktop CPUs are often faster and far more efficient.
High power draw under load makes it less efficient than many-core desktop alternatives, requiring robust cooling and power supply.
- •Single-thread performance is strong thanks to 4.8 GHz turbo.
- •Most games cannot leverage 22 cores; GPU and platform matter more.
- •Not a gaming-focused SKU; high cost and power are hard to justify for pure gaming builds.
- •Intel AMX provides dedicated matrix acceleration for deep learning workloads.
- •Suitable for small to medium models and inference tasks; large-scale training still typically uses GPUs or specialized accelerators.
- •No integrated GPU or dedicated AI accelerator beyond CPU-based AMX/DL Boost.

Architecture Overview
Sapphire Rapids is Intel’s 4th Gen Xeon Scalable architecture, using a chiplet-based design with EMIB to connect compute tiles, built on the Intel 7 process.
CPU Design
The w7-2575X uses 22 performance cores (P-cores) with no efficient cores, each supporting Hyper-Threading for 44 threads. The core complex shares 45 MB of Intel Smart Cache, and the chip is optimized for high single-thread clocks and sustained all-core turbo.
Memory Subsystem
It integrates a quad-channel DDR5 memory controller with official support up to DDR5-4800 and up to 2 TB of RDIMM/LRDIMM memory with ECC, providing high bandwidth for memory-bound workloads.
PCIe & I/O
The CPU exposes 64 PCIe 5.0 lanes directly, enabling multiple high-speed devices such as GPUs, NVMe SSDs, and network cards without bottlenecks common on mainstream desktop platforms.
Overclocking
As an X-series SKU, the w7-2575X has an unlocked multiplier, allowing enthusiasts and workstation power users to overclock on compatible W790 motherboards, though cooling and power delivery must be carefully designed.
- Same Sapphire Rapids architecture but with two fewer cores and slightly higher base clock (3.0 vs 2.5 GHz on w7-2495X).
- W-2500 refresh generally adds cores at each price point and modestly increases base frequencies versus W-2400.
- Platform and I/O capabilities (PCIe 5.0, DDR5-4800, W790 chipset) remain similar between W-2400 and W-2500.
Key Highlights
- 22 high-performance cores and 44 threads for parallel workloads
- 64 PCIe 5.0 lanes for multi-GPU and fast storage configurations
- Quad-channel DDR5-4800 with ECC up to 2 TB
- Intel AMX and DL Boost for AI acceleration
- Unlocked multiplier for overclocking on W790 platforms
- Mature platform with W790 chipset and robust RAS features
- High 250W base and 300W max turbo power draw
- Requires expensive W790 motherboard and robust cooling
- Overkill and costly for gaming or light productivity
- No integrated graphics; discrete GPU required
- Newer platforms may offer better efficiency per dollar
History
The Xeon W-2500 series, including the w7-2575X, is a refresh of Intel’s Sapphire Rapids workstation lineup. The original Xeon W-2400 and W-3400 processors launched in early 2023 as Intel’s first Sapphire Rapids workstation parts, bringing DDR5, PCIe 5.0 and up to 56 cores to single-socket workstations.
By 2024, Intel refreshed the lineup as W-2500 and W-3500, modestly increasing core counts and base frequencies at several price points while keeping the same LGA-4677 platform and W790 chipset. The w7-2575X slots in as a 22-core model below the 26-core flagship w7-2595X, targeting professionals who need more cores than the 18-core w5-2565X but don’t require the extreme 60-core w9-3595X.</br>This refresh allowed Intel to improve performance without a full platform change, emphasizing higher multi-threaded throughput and AI acceleration via AMX, while also adjusting pricing to better compete with AMD’s Threadripper Pro 7000 series in the workstation market.
Improvements over Previous Generation
- Same Sapphire Rapids architecture but with two fewer cores and slightly higher base clock (3.0 vs 2.5 GHz on w7-2495X).
- W-2500 refresh generally adds cores at each price point and modestly increases base frequencies versus W-2400.
- Platform and I/O capabilities (PCIe 5.0, DDR5-4800, W790 chipset) remain similar between W-2400 and W-2500.

Use Cases
Interesting Facts
The w7-2575X is part of Intel’s Sapphire Rapids Refresh, which bumped core counts and base clocks versus the original W-2400 series while keeping the same architecture.
It uses the same LGA-4677 socket and W790 chipset as the earlier Xeon W-2400/3400 series, enabling upgrades within the same platform generation.
X-series Xeon W SKUs are explicitly marketed as “unlocked” for overclocking, unlike most Xeon processors.
Despite being a workstation CPU, it shares its silicon with 4th Gen Xeon Scalable server parts, just with different feature and validation targets.
PassMark lists a CPU Mark around 52,000 and a single-thread rating near 3,300, putting it in the upper tier of workstation CPUs but below top Threadripper Pro models.
Intel’s own benchmarks claim up to 26% faster linear algebra performance for certain Xeon W-2500/3500 SKUs versus previous-gen Xeon W, using workloads like NumPy/SciPy.
The W-2500 series caps out at 26 cores in the w7-2595X, with the w7-2575X sitting just below that at 22 cores.
Built-in accelerators like DSA and the absence of QAT on this SKU reflect Intel’s strategy of tailoring accelerator configurations per Xeon W model.
The processor’s 45 MB Smart Cache is shared across all 22 cores, unlike some heterogeneous designs with separate cache domains for P- and E-cores.
Even though it’s a single-socket part, the W-2500/3500 platform inherits many RAS and reliability features from Intel’s server-oriented Xeon Scalable lineup.
