Market
Workstation / Server
The Intel Xeon 676X is a 32-core, 64-thread workstation and server processor based on the Granite Rapids-WS architecture, designed for heavy multi-threaded workloads like simulation, rendering, and AI development on the LGA4710 platform.
Intel’s Xeon 676X brings 32 Redwood Cove+ P-cores to the LGA4710 workstation platform with 128 PCIe 5.0 lanes and 8-channel DDR5/MRDIMM support. It targets compute-heavy professional workloads like rendering, simulation, and AI development, offering up to 4.
9 GHz turbo and 144 MB of L3 cache in a 275 W TDP envelope. While not a gaming chip, it provides strong multi-threaded performance and platform features for serious workstations.
Specifications
Performance
Excellent multi-threaded performance for professional applications; benefits from 32 P-cores and large cache in workloads like rendering, compilation, and scientific computing.
Very strong for dense virtualization labs, thanks to high core count, 8-channel memory, and extensive I/O for VM storage and networking.
Capable of high-refresh-rate gaming in many titles due to strong single-thread clocks, but not optimized for gaming; mainstream desktop CPUs often deliver better gaming performance per dollar and watt.
Performance-per-watt is reasonable for the core count and platform capabilities, but absolute power is high; efficient compared to older Xeon WS generations, less so vs low-core desktop chips.
- •High single-core boost up to 4.9 GHz helps keep frame rates smooth
- •Not targeted at gamers; few games scale well beyond 16–24 threads
- •Better suited as a gaming streaming + workstation hybrid than a pure gaming CPU
- •Intel AMX with FP16/BF16/INT8 accelerates inference and light training
- •Not a replacement for dedicated GPUs or accelerators on large models
- •Well suited for AI development, prototyping, and CPU-bound inference

Architecture Overview
Granite Rapids-WS brings Intel’s server-class Granite Rapids dies to single-socket workstations, using Redwood Cove+ P-cores on the Intel 3 process with an Intel 7 I/O tile, connected via a mesh fabric and paired with the W890 chipset on LGA4710.
CPU Design
32 Redwood Cove+ performance cores with Hyper-Threading, no efficient cores. Each core has a private 2 MB L2 cache, feeding a shared 144 MB L3 cache and dual AVX-512 FMA units for heavy SIMD workloads.
Memory Subsystem
8-channel DDR5 memory controller supporting DDR5-6400 RDIMMs and MRDIMMs up to 8000 MT/s on supported SKUs, with up to 4 TB capacity and ECC, providing very high bandwidth for memory-bound workloads.
PCIe & I/O
128 PCIe 5.0 lanes from the CPU, enabling multiple GPUs, NVMe arrays, and high-speed network cards without lane sharing, a key advantage over mainstream desktop platforms.
Overclocking
X-series SKUs like the 676X are fully unlocked for overclocking; Intel and partners have already used Xeon 600 to set multiple overclocking world records on W890 motherboards.
- Move from Intel 7 to Intel 3 process for higher density and efficiency

Interesting Facts
The Xeon 676X is one of the boxed Xeon 600 SKUs that Intel sells directly to end users, not just OEMs.
Granite Rapids-WS marks Intel’s return to desktop-focused workstation CPUs after a gap following Xeon W-2500/W-3500.
Xeon 600 chips use the same Redwood Cove+ P-cores as server Granite Rapids but in a single-socket workstation configuration.
The 676X supports MRDIMMs up to 8000 MT/s, but only on the top five Xeon 600 SKUs.
Intel and partners have already used Xeon 600 X-series CPUs to set 10 overclocking world records.
With 128 PCIe 5.0 lanes, a single Xeon 600 can drive more high-speed devices than most dual-socket server platforms.
AMX on Xeon 600 adds native FP16 matrix operations, matching the default precision of many PyTorch/TensorFlow models.
The LGA4710 socket and W890 chipset are brand new for Granite Rapids-WS and are not compatible with older Xeon W platforms.
Despite being a ‘workstation’ CPU, the 676X’s 32 cores and high clocks make it surprisingly capable for enthusiast overclocking.
The 676X’s 144 MB L3 cache is the same size as on higher-core 674X and 658X SKUs, giving it strong cache-per-core vs bigger siblings.
