Intel Xeon 600 uses Redwood Cove+ cores on Intel 3 process technology, increasing core counts to 86 while maintaining 4.8GHz turbo frequencies. The redesigned architecture adds FP16 datatype support in Intel AMX accelerators, delivering 17% faster AI workload performance versus W-3500 series.
Memory Subsystem: 8-Channel DDR5 at 8,000 MT/s
Memory bandwidth becomes the limiting factor in workstation workflows once core counts exceed 32. Intel addresses this with octa-channel DDR5 support across X-series SKUs. Standard RDIMM configurations reach 6,400 MT/s a 33% increase from the previous 4,800 MT/s ceiling.
The breakthrough arrives with DDR5 MRDIMM (Multiplexed Rank DIMM) support, pushing speeds to 8,000 MT/s. This matters for memory-bound operations like fluid dynamics simulations and large dataset manipulations. Maximum capacity hits 4TB per system. Error-correcting code (ECC) memory remains standard, maintaining data integrity during multi-day rendering jobs.
Platform Connectivity: 128 PCIe 5.0 Lanes
Modern workstation builds demand connectivity for multiple GPUs, NVMe arrays, and high-speed network adapters. Intel Xeon 600 provides 128 lanes of PCIe 5.0 bandwidth directly from the CPU. This eliminates the lane-sharing compromises forced by consumer platforms.
A typical configuration might allocate 64 lanes to dual professional GPUs, 32 lanes to eight NVMe Gen5 drives, and 16 lanes to CXL 2.0 memory expansion modules. The remaining bandwidth handles network cards and capture devices without bottlenecking. CXL 2.0 support enables memory pooling across multiple systems relevant for render farms and AI training clusters.
The W890 chipset complements CPU connectivity with integrated Wi-Fi 6E and discrete Wi-Fi 7 support. For environments requiring deterministic network performance, multiple 10GbE ports can be added without stealing GPU lanes.
AI Acceleration: FP16 Support in Intel AMX
Intel Advanced Matrix Extensions (AMX) appear in Xeon 600 cores with a critical update: FP16 datatype support. Previous generations handled BF16 and INT8 operations, but FP16 is the native format for many AI frameworks including PyTorch and TensorFlow.
SPECworkstation 4.0 AI benchmarks show 17% performance gains versus the W9-3595X when running machine learning inference tasks. Intel attributes this to AMX executing FP16 matrix multiplications without type conversion overhead. The company released Open Image Denoise 2.4 specifically optimized for Xeon 600’s FP16 capabilities.
Topaz Labs Video Upscaler, a tool content creators use for AI-based resolution enhancement runs 29% faster on the Xeon 698X compared to prior generation processors. This translates to hours saved when upscaling feature-length footage from 1080p to 4K.
For organizations comparing on-device AI versus cloud inference: Xeon 600 eliminates data egress costs and latency while maintaining full control over proprietary datasets.

Intel Xeon 600 delivers 17% faster AI performance through FP16 datatype support in AMX accelerators. Real-world testing shows 29% speed improvements in Topaz Labs Video Upscaler and accelerated performance in PyTorch inference tasks compared to W-3500 series.
Performance Claims: 61% Multi-Thread Gain
Intel’s headline claim compares the 86-core Xeon 698X against the 64-core W3595X in Cinebench 2026. The 61% multi-thread improvement aligns with the 34% core count increase (86 vs 64), with architectural enhancements contributing additional performance through improved power efficiency and cache optimization.
Blender Junkshop rendering completes 74% faster on the Xeon 698X versus the W9-3595X, a scenario where thread scaling matters more than per-core frequency. Financial services workloads in SPEC Workstation 4.0 show the same 61% advantage, while life sciences applications also demonstrate double-digit improvements.
Not all workloads scale equally. SPEC’s productivity category showed minimal performance differences between high-core-count configurations, indicating office applications don’t leverage the additional cores effectively. Professionals should match core counts to their specific applications a 48-core Xeon 678X may deliver better value than the 86-core flagship for workloads that saturate at 32 threads.
