What the Xeon 674X is
The Xeon 674X is a 28 core server processor from the Xeon 6 family under the codename Granite Rapids. All 28 cores are Performance-cores, and with Hyper-Threading the part presents 56 threads. The base frequency is 3.0 GHz with maximum turbo to 4.9 GHz through Turbo Boost Max 3.0, 4.7 GHz through Turbo Boost 2.0, and 4.3 GHz all-core turbo. The shared last level cache totals 144 MB. Intel aims the part at simulation, rendering, data science, and virtualization hosts that want high boost clocks with more threads than the 24 core class.
Intel rates the processor base power at 270 W with maximum turbo power at 324 W. The part is built on Intel 3 and carries no integrated graphics, so display output or GPU compute needs a discrete card. Scalability is 1S, which means each system uses exactly one Xeon 674X. ECC memory is supported, and the feature set includes AVX-512 with two FMA units per core plus AMX with FP16 acceleration for AI math. The X suffix marks an unlocked multiplier for tuning on boards that permit it.
The processor launched in the first quarter of 2026 at 2419 dollars Intel recommended customer price. Intel announced the Xeon 600 family in February 2026 with availability through hardware partners. It sits between the 24 core Xeon 658X and the 32 core Xeon 676X, matching their 144 MB of cache and 4.9 GHz boost while splitting the difference in cores and envelope.
Socket and motherboard compatibility
The Xeon 674X fits the LGA 4710 socket, a land grid array with 4,710 contacts that also hosts Sierra Forest parts. The package is FCLGA4710. Single socket workstation and server boards built for the Granite Rapids platform generation are the natural match. Compatibility still follows the board vendor CPU support list for each model, including the minimum BIOS revision that carries Granite Rapids microcode.
The socket file for this site carries no desktop chipset groups, so there is no retail chipset pick to copy. The Socket vs chipset: what decides whether a CPU works explains how socket fit differs from chipset and firmware support, and that distinction matters here because workstation boards qualify processors individually. Buyers should confirm the Xeon 674X on the vendor list with the planned BIOS revision before ordering memory or cooling.
Because the part is 1S only, dual socket boards are not an option. Cooling follows the board vendor list for 270 W parts, which in practice means large tower air coolers with server airflow or liquid cooling qualified per chassis. There is no boxed cooler. System integrators size cooling for the 324 W maximum turbo power so the processor can hold boost under sustained all core load.
Memory, PCIe and cooling
The memory controller supports DDR5 up to 6400 MT/s in 8 channels with up to 4 TB per socket, plus MRDIMM memory up to 8000 MT/s on supported boards. ECC is supported, and RDIMM types fit the enterprise use case. Final speed follows DIMM population per channel, so two DIMMs per channel lowers the rate and vendors publish tested layouts for full capacity. Eight channels give 409.6 GB/s of theoretical bandwidth at DDR5-6400, which feeds the 28 cores in bandwidth heavy simulation and rendering.
For I/O the chip provides PCI Express 5.0 with up to 128 lanes for multiple GPUs, NVMe storage, and high speed networking at full Gen 5 bandwidth. With no UPI links active, all traffic stays inside the single socket or moves over PCIe and CXL 2.0. The platform also carries DMI 4.0 to the board controller for management and onboard devices. The lane count leaves room for dual x16 GPU slots plus several Gen 5 NVMe drives without switches.
Power and cooling center on 270 W base with 324 W maximum turbo. Firmware sets sustained and burst limits, and rack planners should budget power and airflow for continuous load at full turbo rather than base power alone. The package uses the server carrier and retention mechanism of the board, not a desktop socket lever and clip. A 270 W envelope in a single socket demands front to back airflow and a chassis rated for continuous workstation duty.
Upgrade paths
Within LGA 4710 the path up is a 32 core Xeon 676X or a 48 core Xeon 678X on the same board where power and cooling allow. Those parts keep 8 memory channels and 128 PCIe lanes while adding cores and cache for heavily threaded work. The vendor list shows which higher parts the board and BIOS revision accept, and the heatsink may need to change for the higher envelope.
A larger change of platform means a new board and new memory population. The LGA 7529 platform serves the biggest Granite Rapids server configurations with more memory channels, and reaching it requires different boards, heatsinks, and firmware rather than a drop in replacement. Buyers moving from a desktop socket should plan for workstation chassis, high capacity power, and ECC RDIMM memory rather than desktop DIMMs.
For systems built around the 674X, the board, memory, and I/O define the ceiling. Populating all 8 memory channels and spreading GPUs and NVMe drives across the 128 lanes keeps the 28 cores fed. When thread count limits the workload, a same socket part with more cores is the next step without changing memory or boards.
Frequently asked questions
What socket does the Intel Xeon 674X use?
The Intel Xeon 674X uses LGA 4710. It fits single socket workstation and server boards built for Granite Rapids parts. Always confirm the part on the board vendor CPU support list.
What memory does the Xeon 674X support?
DDR5 up to 6400 MT/s in 8 channels up to 4 TB with ECC, plus MRDIMM up to 8000 MT/s on supported boards. Final speed follows the DIMM type and population per channel.
How many PCIe lanes does the Xeon 674X provide?
Up to 128 lanes of PCI Express 5.0 for multiple GPUs, NVMe storage, and high speed networking. The part has no active UPI links and runs in single socket systems only.
Can two Xeon 674X processors work together?
No. Scalability is 1S, so each system uses exactly one Xeon 674X. Workloads that need more cores move to a higher core part on the same socket or to a larger platform.
