The Intel Xeon 600 Granite Rapids-WS series has been leaked, offering workstation users a first look at a lineup delivering up to 336 MB of cache. Granite Rapids should not be mistaken for Granite Ridge, which refers to the desktop Ryzen 9000 series based on the Zen 5 architecture. In contrast, Granite Rapids represents Intel’s Xeon CPU platform designed for servers and an upcoming workstation lineup. The full product stack was recently revealed by the leaker known as momomo_us, along with an early Geekbench entry for the Xeon 654 that provides the first clear details of how Intel is adapting its Xeon 6 P-core dies for workstation environments rather than datacenter deployments.
The leaked Granite Rapids-WS product family includes at least eleven models: 698X, 696X, 678X, 676X, 674X, 658X, 656, 654, 638, 636, and 634. Only the base clock speeds and L3 cache capacities are disclosed. At the top of the lineup, the flagship Xeon 698X features a base clock of 2.0 GHz paired with 336 MB of L3 cache, while the 696X raises the base clock to 2.4 GHz while maintaining the same cache size. At the lower end of the range, the Xeon 634 comes with 48 MB of cache and runs at 2.7 GHz. The midrange segment includes models such as the 678X at 2.4 GHz with 192 MB of cache, as well as several configurations offering 72 MB of cache in the 3.0 to 3.2 GHz frequency range.
The first benchmarked model, the Xeon 654, offers additional insight into the architecture. According to Geekbench results, the processor includes 18 cores and 32 threads, achieving 2,634 points in single-core tests and 14,743 points in multi-core performance. Boost clocks reached 4.77 GHz, with a minimum observed clock speed of 2.9 GHz, which aligns closely with the leaked 3.1 GHz base frequency. The SKU listing confirms that the Xeon 654 has 72 MB of L3 cache, consistent with other small-cache entries in the leaked series.
Where the workstation Granite Rapids-WS models differ significantly from the datacenter Granite Rapids P-series is cache capacity at the upper end. Intel’s Xeon 6980P and 697X-P datacenter processors scale up to 128 and 120 cores respectively, with up to 504 MB of L3 cache. Granite Rapids-WS, however, maxes out at 336 MB of cache even on the top 698X and 696X models. Since cache size scales with core count in the server lineup, a one-third reduction in L3 cache on the workstation flagship indicates a core ceiling below 128 cores, and the leak suggests a configuration closer to an 80-core maximum.
Granite Rapids-WS is expected to utilize the same Redwood Cove P-cores, Intel 3 process technology, DDR5 memory support, and PCIe 5.0 interface as its datacenter-oriented counterparts. It targets workstation professionals requiring higher memory bandwidth and increased core counts compared to desktop platforms, yet without entering datacenter pricing territory. For comparison, the flagship AMD Threadripper model, the PRO 9995WX, features 96 cores and 384 MB of L3 cache, with the series spanning 8-core to 96-core designs and a 350 W TDP.
With workstation CPUs entering a new era of extreme multithreading, high cache density, and elevated thermal loads, reliable thermal management becomes essential. Maxtor high-performance thermal grease is engineered specifically to address the increasing thermal demands of next-generation CPUs such as the Intel Granite Rapids-WS series. With optimized viscosity, exceptional thermal conductivity, and long-term stability, Maxtor thermal solutions ensure consistent heat transfer and sustained performance even under continuous full-core workloads. As workstation platforms evolve toward higher frequencies and larger caches, Maxtor provides the thermal reliability required to maintain system efficiency, hardware lifespan, and performance integrity for professionals relying on advanced computing power.
