28-core Xeon Gold 5512U for single-socket servers

The Intel Xeon Gold 5512U is a 28-core server processor built for single-socket platforms. It delivers 56 threads at a 2.1 GHz base frequency and reaches 3.7 GHz maximum turbo frequency. The LGA 4677 package integrates a 52.5 MB L3 cache and an eight-channel memory controller rated for 4800 MHz operation.

LGA 4677 socket with 185 W TDP

This processor requires a motherboard equipped with an LGA 4677 socket and cooling rated for 185 W thermal design power. The platform provides 80 PCI Express 5.0 lanes for high-bandwidth I/O. Maximum supported memory capacity is 4 TB across eight channels.

Suits dense single-socket deployments.

The 5512U scales to one socket only, so it fits density-optimised single-node servers and workstations. Buyers who need multi-socket scalability should look at processors that support 2S or higher configurations. Workloads demanding integrated graphics or specialised accelerators not listed here will require a different platform.

Questions about this item

How does the 2.1 GHz base frequency translate to actual server throughput?

The 28 cores and 56 threads run at 2.1 GHz continuously, with a 3.7 GHz max turbo for burst workloads, while the 52.5 MB L3 cache reduces latency on data-heavy tasks.

What does the PCIe 5.0 interface with 80 lanes cap in practice?

The 5.0 revision and 80 lanes set the maximum aggregate bandwidth available for add-in cards and storage controllers attached to this socket.

What physical space and power does the LGA 4677 package need?

It fits a LGA 4677 socket and has a 185 W thermal design power, so the chassis and cooler must accommodate that heat load.
