What the Xeon Silver 4510T is
The Xeon Silver 4510T is the 12-core telecom member of the late 2023 Silver refresh for LGA 4677 boards from the fourth quarter of 2023. Twelve Golden Cove cores with hyperthreading give 12 cores and 24 threads, with base at 2.0 GHz and up to 3.7 GHz turbo. The package carries 30 MB of Smart Cache. The 115 W envelope suits single and dual socket network servers with tuned power. ARK files it under the 5th Gen Xeon Scalable collection while the codename field says Sapphire Rapids, so this page follows the master list codename.
Lower power with 12 threads suits telco edge racks that cap per-node watts. Eight channels of DDR5 feed 12 cores for virtualized functions. Eighty Gen5 lanes with Flex Bus and CXL serve NICs and accelerators across sockets. Speed Select profiles trade cores for clocks within the SKU.
Telecom buyers land here for 12 threads at 115 W with profile flexibility. Mixed network functions plus management tasks fit well, while 150 W Silver parts suit denser hosts. Server boards need C741 class chipsets with the Silver SKU on the CPU list, not W790 workstation boards. The Socket vs chipset: what decides whether a CPU works guide covers server board choice.
Socket and motherboard compatibility
The 4510T fits LGA 4677 on single and dual socket server boards with LGA 4677 retention and server power delivery. Two UPI links at 16 GT/s enable dual socket pairing. W790 workstation boards target W-series chips instead.
Server chipset choice decides management and IO breadth rather than CPU fit. Speed Select profiles are set in firmware per deployment.
Memory, PCIe and cooling
DDR5 to 4800 MT/s in 8 channels feeds 12 cores for network duty. Population with matched DIMMs holds rated speed.
Eighty Gen5 lanes with Flex Bus and CXL per CPU wire NICs, accelerators and NVMe. Cooling is a 115 W server heatsink with front-to-back airflow.
Upgrade paths
On LGA 4677 the upward moves are higher-core Silver parts where VM counts grow, or adding a second 4510T socket where boards allow 2P. Memory growth and NIC additions often help more than cores.
Outside mainstream Silver, Bronze parts on LGA 4677 trim cost for lighter loads.
Frequently asked questions
What socket does the Xeon Silver 4510T use?
LGA 4677 on single and dual socket server boards.
What does T mean on the 4510T?
A telecom-tuned SKU with lower 115 W power and Speed Select profiles for network servers.
Is the 4510T Sapphire Rapids or Emerald Rapids?
ARK files it under 5th Gen collection with a Sapphire Rapids codename field; this page follows the master list codename Sapphire Rapids.
Can the 4510T run in dual socket?
Yes, UPI links enable dual socket pairing on server boards.
