What the Xeon Gold 6336Y is
The Xeon Gold 6336Y is a 24-core server processor that Intel released in April 2021 with the Ice Lake-SP range for 2-socket systems. Its Sunny Cove cores run 2.4 GHz base to 3.6 GHz turbo with Hyper-Threading for 48 threads. Cache is 36 MB with 1.25 MB of L2 per core.
The Y suffix marks Speed Select Performance Profile support for cloud roles that tune cores to workload needs. The 10 nm process pairs 8 channels of DDR4-3200 with 64 PCIe 4.0 lanes for fast storage and network cards. Two-socket operation keeps scale out cost below larger Gold builds.
There is no integrated graphics on this model, so setup relies on board BMC graphics. ECC memory support guards data across long uptime. The socket package is FCLGA4189 at 77.5 × 56.5 mm.
Socket and motherboard compatibility
The 6336Y fits the LGA 4189 socket on Whitley boards for Ice Lake-SP. Cedar Island boards for Cooper Lake share the socket name but do not accept this chip, so the board generation must match the processor generation. The server vendor CPU support list names the exact boards for Y suffix parts.
Two-socket operation is possible with Xeon Gold dual processor parts, with single socket boards possible where the vendor qualifies them. A buyer running profile tuned roles should confirm the board firmware exposes the SST-PP options before ordering.
Check memory population rules for 2-socket boards when ordering. Sixteen DIMM slots per socket is the platform shape, and both sockets should match in capacity and speed.
Memory, PCIe and cooling
The memory controller supports DDR4 up to 3200 MT/s in 8 channels, up to 4 TB per socket, with ECC support. Tuned cloud nodes use RDIMM pairs across all channels for bandwidth with integrity. The controller does not accept DDR5.
The CPU supplies 64 PCIe 4.0 lanes per socket for network cards and NVMe storage. Two-socket boards split lanes across slots and onboard controllers, so the board specifications state which slots reach full speed. Three UPI links at 11.2 GT/s carry socket to socket traffic.
At 185 W, vendor-qualified performance air heatsinks with strong directed chassis airflow are needed. Mounting is board specific with no retail pattern, and the CPU cooler compatibility by socket guide explains why server sockets list no desktop bracket.
Upgrade paths
Against the Intel Xeon Gold 6342, the 6336Y trades clocks for profile tuning at lower power. The 230 W part holds higher sustained speed, while this Y part tunes cores to workload needs at 185 W. Both share Whitley boards and 24-core layouts.
Moving to LGA 4677 needs new boards and DDR5 memory for Sapphire Rapids generations. The 6336Y fits a tuned cloud node, a dense virtual farm, or a scale out tier with profile needs.
For used buyers, the Y part makes sense when profile tuning matters. When sustained speed matters more, the 6342 gives higher clocks on the same board.
