Server CPU for eight-core workloads

The Intel Xeon Silver 4309Y is an eight-core processor built for LGA 4189 platforms. It delivers 16 threads at a 2.8 GHz base clock and supports DDR4 2666 across eight memory channels. The part targets single-socket or dual-socket servers needing moderate parallel throughput.

Sustained 105W operation with turbo headroom

Under continuous load the processor maintains its 105W thermal design power while the 3.60 GHz max turbo frequency provides burst capacity for short spikes. The 12MB L3 cache and 10 nm Ice Lake core help keep latency low during extended compute tasks such as virtualization hosting or database serving.

Replaces older dual-socket Xeon Silver parts

The jump is worthwhile when moving from earlier Xeon Silver models that lack PCI Express 4.0 and the 64-lane ceiling. It is not suited for buyers who need more than eight cores per socket or who require memory speeds beyond DDR4 2666.

Questions about this item

How much heat does the 105W TDP generate when the Xeon Silver 4309Y runs at full load all day?

The processor has a 105W thermal design power, so sustained full-load operation will dissipate up to 105 watts of heat that your server cooler must handle continuously.

Which memory modules and motherboard socket are required for the LGA 4189 Xeon Silver 4309Y to function?

You need a motherboard with an LGA 4189 socket and DDR4-2666 registered ECC DIMMs; the integrated controller supports eight memory channels for full bandwidth.

Will the PCIe 4.0 lanes on this 4309Y work with older PCIe 3.0 expansion cards I already own?

Yes, the 64 PCI Express 4.0 lanes are backward compatible, so your existing PCIe 3.0 cards will operate at their native 3.0 speeds when installed.
