Intel's Xeon 600 Series: A New Workstation King, or Just Playing Catch-Up?
Intel has officially unleashed its new Xeon 600 series processors for client workstations, a move we view as a significant, albeit long-overdue, update for the company's high-end professional platform. Borrowing the "Granite Rapids" technology previously reserved for the server room, this fresh lineup packs a punch with 11 different processors, offering up to 86 performance cores and promising considerable gains for the most demanding workloads in engineering, AI development, data science, and media creation.
The launch also sees Intel consolidating its Xeon W-2x00 and W-3x00 branding under a unified Xeon 600 series, a commendable effort to streamline what has become a somewhat convoluted professional workstation offering. These new chips are designed to pair with the new Intel W890 Chipset and are slated to begin shipping in late March 2026. They'll be available both as standalone units and integrated into systems from major partners like Dell, HP, Lenovo, and Supermicro.
The Core of the Matter: Redwood Cove+ and the P-Core Philosophy
At its heart, the Xeon 600 series processors are built on Intel's Redwood Cove+ P-core architecture and fabricated using the Intel 3 process. We find it particularly interesting that, unlike some of Intel's consumer offerings, these workstation CPUs exclusively utilize P-cores (Performance-cores) with Hyper-Threading, completely omitting E-cores (Efficiency-cores). For professional workloads where consistent, predictable performance is paramount, this P-core-only approach makes a lot of sense, prioritizing raw computational power over multi-faceted core design.
The product stack is broad, ranging from the accessible 12-core Xeon 634, priced at $499, all the way up to the behemoth Intel Xeon 698X Processor, which commands a price tag of $7,699. The flagship Xeon 698X is an 86-core, 172-thread monster, boasting a 2 GHz base frequency, a 4.8 GHz turbo frequency, and a robust all-core turbo frequency of 3 GHz. It also features a substantial 336 MB of L3 cache, a base TDP of 350 watts, and a maximum turbo power of 420 watts.
Several models, including the 698X and the 64-core 696X ($5,599), are based on XCC (Extreme Core Count) dies with two compute tiles per package, indicating Intel's approach to scaling performance. Mid-range and other high-end parts, such as the 48-core 678X ($3,749) and the 24-core 658X ($1,699), utilize HCC (High Core Count) dies. While many SKUs will be available as boxed retail units, some, including the top-tier 698X, are primarily aimed at OEM integration, which might limit direct consumer access to the most powerful parts. Enthusiasts will be pleased to know that most processors in the series are unlocked for overclocking, a rare treat in the Xeon space, though the entry-level 656, 654, 638, 636, and 634 models remain locked.
A Look at the Top Tier: Intel Xeon 698X vs. AMD Threadripper PRO 7995WX
To truly understand Intel's play, we must consider the competitive landscape. While Intel notably sidestepped direct comparisons to AMD's Threadripper Pro 9000 Series, the specs speak volumes.
The Threadripper PRO 7995WX, AMD's flagship, offers 96 cores and 192 threads, running on a more advanced 5nm process (Zen 4 architecture) and featuring a larger 480MB of L3 cache. It also boasts higher base and boost clock speeds. While Intel's pricing for the 698X at $7,699 positions it somewhat competitively, especially compared to the higher end of Threadripper Pro 7995WX pricing (which can reach over $10,000), the core count and potentially superior process node from AMD suggest Intel has its work cut out to truly claim dominance in the absolute highest-end. Many in the community have already voiced their surprise at Intel's "complete omission of Threadripper / Epyc comparisons" in their marketing, speculating that a head-to-head might not have looked favorable for Intel, particularly concerning single-core performance.
Memory and Connectivity: Bandwidth for the Busiest Workloads
The Xeon 600 platform brings noteworthy enhancements in memory and I/O capabilities. All SKUs now support DDR5-6400 memory speeds for one DIMM per channel (1 DPC). For the top half of the series (processors with 28 cores and higher), Intel has included support for Multiplexed Rank DIMMs (MRDIMM), pushing effective memory speeds up to DDR5-8000. The platform supports a maximum memory capacity of 4TB and retains essential enterprise features such as RAS (Reliability, Availability, Serviceability) and ECC memory support.
These memory advancements are critical for data-intensive applications. Faster memory means less time waiting for data, directly impacting large simulations, massive datasets in AI, and high-resolution media editing. The trade-off, however, is that MRDIMM support, while offering higher bandwidth, may come at the cost of maximum memory capacity and current availability. Furthermore, the high-end DDR5 RDIMMs required for these platforms are notoriously expensive, with a 1TB kit of DDR5-6400 RDIMMs estimated to cost around $28,000. This is a significant consideration for anyone planning a high-capacity workstation.
Connectivity is equally impressive, with up to 128 PCIe Gen 5.0 lanes available directly from the CPU on supporting models. This provides immense bandwidth for multiple high-speed storage solutions, professional GPUs, and other accelerators, making multi-GPU setups or extensive NVMe storage arrays a breeze. The inclusion of CXL 2.0 support is another big win, facilitating advanced memory pooling and single-level switching capabilities. For AI and deep learning professionals, the integration of Intel AVX-512 and AMX (Advanced Matrix Extensions) is welcome, with AMX now supporting Integer8, Bfloat16, and FP16 data types – crucial for accelerating diverse AI workloads. And, as expected for a professional platform, Intel vPro technologies are included, offering hardware-enhanced security and management features essential for enterprise deployments.
Benchmarks: Intel's Story, Our Interpretation
Intel's provided performance comparisons against its previous generation 60-core Xeon W9-3595X processor show promising generational improvements. The new 86-core Xeon 698X processor demonstrates:
- Cinebench 2026: Up to 9% higher single-threaded performance and up to 61% higher multi-threaded performance.
- Blender Junkshop render: Completed 74% faster.
- AI-powered upscaling (Topaz Labs Video Upscaler): 29% faster.
- SPEC Workstation 4: Shows a 17% improvement in AI workloads, 22% in the energy subcategory, 61% in financial services, 19% in life sciences, and 10% in media and entertainment.
While these numbers are certainly positive against its predecessor, we can't help but feel a pang of skepticism regarding the absence of direct comparisons to AMD's Threadripper Pro lineup. Performance figures always tell a selective story, and without a contemporary rival in the mix, it's hard to gauge true competitive standing. It leaves us wondering if Intel is truly leading the pack or merely closing a gap. Some community reactions suggest that Intel might have focused on price competitiveness for lower-end models and superior core-per-dollar ratios for certain SKUs against Threadripper 9000, which can be a strong selling point for businesses.
Intel is also collaborating with Ocbase to integrate support for the Xeon 600 Processor family into the OCCT app, offering dynamic overclocking controls, platform telemetry, stability testing, and configurable benchmarking. In a partnership with ASUS, Intel utilized a Xeon 698X Processor and an ASUS Pro WS W890E-SAGE SE motherboard to establish several new overclocking world records across 10 benchmarks and secure 10 global first-place submissions in various categories. This focus on overclocking, traditionally less common in the Xeon world, is an exciting development and could offer an edge for users willing to push the limits.
The W890 Platform: Foundation for a New Era
The new Xeon 600 processors operate on the Intel W890 Chipset, which introduces modern features like Wi-Fi 7 support. The chipset connects to the host CPU via a DMI Gen4 x8 link, providing nearly 16GB/second of bandwidth – ample for the integrated peripherals. Motherboards based on the W890 chipset are expected to offer 1Gbps or 2.5Gbps LAN ports.
Giga Computing has already announced two new enterprise-grade workstation motherboards, the GIGABYTE MW94-RP0 and MW54-HP0, designed for the Xeon 600 processors. The MW94-RP0, targeting the highest-end, supports up to 86 CPU cores, 8-channel memory (including MRDIMMs), a staggering 128 PCIe 5.0 lanes with six Gen5 x16 expansion slots, and dual 10Gb/s LAN ports. The MW54-HP0 caters to models with 4-channel memory and 80 PCIe 5.0 lanes, featuring five Gen5 x16 expansion slots and dual 2.5Gb/s LAN ports. We expect to see robust W890 motherboard offerings from other key partners like Asus, Gigabyte, and Supermicro.
It's important to note a subtle but crucial distinction: while the Xeon 600 shares the LGA4710-2 socket with server Granite Rapids SKUs, workstation parts specifically require the W890 chipset to boot. Additionally, certain accelerators like IAA, QAT, and DLB are disabled on workstation boards, while DSA (Data Streaming Accelerator) remains enabled. This segmentation ensures distinct market positioning between server and workstation platforms.
Pricing and Availability: Premium Performance, Premium Cost
The Intel Xeon 600 series processors are priced between $499 for the 12-core Xeon 634 and $7,699 for the 86-core Xeon 698X. They will be available for purchase as standalone chips and within complete systems from late March 2026. Hardware partners for the launch include Dell, HP, Lenovo, Supermicro, Boxx, and Puget Systems. The entry-level pricing is arguably appealing, especially when considering the competitive landscape, where AMD doesn't currently offer anything in the same price range for lower core count workstation CPUs.
Our Key Considerations
While the Xeon 600 series undeniably brings significant advancements to Intel's workstation portfolio, potential buyers should approach this launch with a few critical factors in mind.
Firstly, the processors are built on the Intel 3 process, which, while an improvement, is not Intel's absolute latest, such as the newer Intel 1.8A process. In contrast, AMD's competing Threadripper Pro 7000WX series utilizes a 5nm process (Zen 4 architecture), which often implies a power efficiency and IPC advantage.
Secondly, and perhaps our biggest point of contention, is Intel's decision not to provide formal performance comparisons against AMD's competing Ryzen Threadripper Pro 9000 Series. Instead, they opted to compare against their own older Xeon and Core chips. This strategic avoidance naturally leads us to question how the new Xeons truly stack up against their most direct rival, particularly in workloads where Threadripper Pro has historically excelled. The community has picked up on this, with many users in online discussions noting the absence of these comparisons and speculating about potential performance gaps, especially in single-threaded tasks where Threadripper is often perceived as stronger.
Performance can also vary widely based on specific workloads; the Xeon 698X, for instance, showed underperformance compared to its predecessor in some product design tests within SPEC Workstation 4. This highlights the importance of matching the right CPU to your exact application profile, rather than relying solely on broad benchmark figures.
Additionally, while MRDIMM support offers higher bandwidth, it may trade off maximum memory capacity and, as we've noted, the current cost of high-end DDR5 RDIMMs necessary for these platforms is astronomical, with a 1TB kit of DDR5-6400 RDIMMs estimated around $28,000. This could significantly inflate the total system cost. Finally, users considering overclocking, while a tantalizing prospect for Xeon, should be aware that altering clock frequency or voltage may void product warranties and potentially reduce stability, security, performance, and the lifespan of components. As always, proceed with caution and at your own risk.
