Intel Xeon Silver 4314 Processor

The Intel Xeon Silver 4314 — 16 cores and 32 threads at 2.40 GHz base / 3.40 GHz turbo, 24 MB cache, 135 W TDP, FCLGA4189. Supplied from stock with a 1-year warranty.

Why the 4314 is the volume favourite of Ice Lake Silver

The 4314 belongs to the 3rd Gen Xeon Scalable (Ice Lake-SP) family, which Intel launched in Q2 2021 on a 10 nm process. Silver is Intel’s entry-to-mainstream tier for dual-socket servers, and the 4314 is its mid-range sweet spot: 16 cores — four more than the Cascade Lake Silver 4214 it replaces — with a 24 MB cache and the wider memory and I/O subsystem Ice Lake introduced.

Ice Lake was the generational turn for the Xeon platform: memory moved to 8 channels of DDR4-2666 (up to 6 TB per socket) and the PCIe bus to PCIe 4.0 with 64 lanes, while the two UPI links gained speed to 10.4 GT/s. For fleet refreshes of Silver-class servers, the 4314 delivers a large step in memory bandwidth and I/O over any Cascade Lake part while staying inside a 135 W budget.

Technical specifications

Instruction set extensions: Intel SSE4.2, AVX, AVX2 and two AVX-512 FMA units. Security and management: AES-NI, Total Memory Encryption, SGX (8 GB EPC with Intel SPS), CET, TXT, VT-x with EPT and VT-d, plus Intel Optane persistent memory support.

Servers that commonly take this processor

The 4314 fits Ice Lake platforms built on the LGA4189-5 socket. The server families we ship against most often:

• Dell PowerEdge 15G R650, R750, R750xa, XS7520 (Ice Lake CPU board variants)
• HPE ProLiant Gen10 Plus DL360, DL380, DL560
• Lenovo ThinkSystem V2 SR630 V2, SR645 V2, SR650 V2
• Supermicro X12 generation boards
• Cisco UCS M6 C220 M6, C240 M6, X210c M6

One caution when buying on the secondary market: although Cascade Lake and Ice Lake parts share the 4189-pin footprint, the two socket variants (LGA4189-4 vs LGA4189-5) are electrically different — an Ice Lake 4314 does not POST in a Cascade Lake board or vice versa. Tell us your exact server model when you enquire and we will confirm compatibility and the required BIOS level.

How it compares across generations

Choose the 4314 when you are keeping an Ice Lake server alive, adding a second CPU to a 2S machine, or want DDR4 stock at a Silver price. Move up to the Silver 4416+ only if the platform is Socket E (FCLGA4677) and DDR5 matters. Step to the Gold 6258R where the chassis and firmware already support a 205 W Cascade Lake part and 28 cores are genuinely needed.

How each processor is tested before it ships

1. Visual inspection of the integrated heat spreader, substrate and contact pads; the sSpec laser marking (SRKXL on our 4314 stock) is verified against the Intel specification sheet.
2. Burn-in on an Ice Lake diagnostic board with a matched pair of DDR4 RDIMMs.
3. All eight memory channels and the first PCIe lanes are validated, then the CPU is identified in the BIOS and in the operating system.
4. A sustained multi-threaded load test at full core count, with the clock and thermal readings recorded.
5. Final clean, then packaging in an anti-static tray with foam, which is how it arrives to you.

Warranty and lead time

Every processor is covered by a 1-year warranty against defects in workmanship and function. If a part fails within the period we replace it or refund it, and we cover return shipping on a verified fault. Stock is held in our own warehouse and normally dispatches within three to seven working days; tracking is issued at dispatch.

Purchasing and volume enquiries

The minimum order quantity for this processor is 2 units. Price is quotation-based rather than listed, because server CPU pricing moves with each incoming batch — send us the quantity you need and we will come back with a firm quote and the current lead time. Larger quantities are tested in matched batches so you receive consistent steppings.
