Intel Xeon Gold 6248
A 20-core / 40-thread 2nd Gen Xeon 'Cascade Lake' processor on LGA3647 (Socket P), running 2.5GHz base with 3.2GHz all-core and 3.9GHz maximum turbo, 27.5MB L3 cache and a 150W TDP. It is a 2nd Gen Xeon Scalable part on LGA3647: a dual-socket board with two of these gives 40 cores, with DDR4-2933 and PCIe 3.0 on the platform, and the same socket family as the 1st Gen parts.

The Xeon Gold 6248 belongs to the 2nd Gen Xeon Scalable (Cascade Lake) generation, built on LGA3647 (Socket P) with PCIe 3.0, 48 lanes and 6-channel DDR4-2933. Two things decide whether a given CPU is the right buy. First, the generation: LGA3647 (1st and 2nd Gen) and LGA4189 (3rd Gen) are different sockets, so a board takes one generation only - and the BIOS revision has to support the specific model. Second, the pair: a dual-socket build needs two identical CPUs (same sSpec) to train, which is why we quote matched pairs from a single lot. On the figures: 2.5GHz base is guaranteed, 3.2GHz is the sustained all-core turbo and 3.9GHz is single-core maximum. Full Intel Xeon range. Specification figures are transcribed from the public 2nd Gen Xeon Scalable processor list that mirrors Intel's published data; the sSpec is read from the physical part and confirmed against your order.
Transparent Pricing
2026 Reference Pricing by Configuration
We do not publish a fixed price for used Xeon Scalable processors. The secondary market reprices weekly as hyperscaler refresh cycles land, so every CPU is quoted against the tray or pull stock we can confirm for your quantity, at the rate in force that day. If you need a number to budget against, tell us the quantity and the platform and we will put a firm figure in writing with the date it holds until.
Single CPU
On Request
Individually tested, with the sSpec and marking checked against your order before dispatch.
Matched Pair
On Request
Two CPUs from one lot for a dual-socket board, so the pair trains at the same stepping and you avoid a mixed pair.
Volume (10+ CPUs)
On Request
Batch quantities consolidated from our Hong Kong warehouse, with freight and packing quoted alongside the CPU.
No price is published on this page by choice rather than omission: used Xeon pricing moved too fast in 2026 for a static figure to stay honest. Send quantity and platform and we will quote against live stock. Related reading: buying server CPU under memory inflation and Xeon vs EPYC.

Quality Process
What We Check Before a Xeon Gold 6248 Ships
Heat-Spreader Marking Read
The laser-etched marking on the heat spreader is read and photographed, and the model and sSpec are checked against your order before anything is packed. A CPU that looks right but carries a different sSpec is the most common failure in this market.
Contact Pads Inspected
The LGA contact pads are inspected under magnification for bent or bridged contacts and for corrosion. Pads cannot be straightened reliably, so a damaged unit is rejected rather than shipped.
Full POST on a Reference Board
Each CPU is seated on a reference board of the correct socket, all cores and all memory channels are exercised, and the POST result is logged per unit.
Thermal Behaviour Logged
Load temperatures are recorded against the TDP this part is rated at, so degraded heat-spreader contact is caught before dispatch.
Serial Logging
The unit is logged against your order line by line, so a mixed or short shipment can be traced to the CPUs actually dispatched.
Report in the Box
Every unit ships with its per-machine diagnostic report and warranty. Full process: inspection guide.
Frequently Asked Questions
How much does the Intel Xeon Gold 6248 cost?
We quote rather than publish. Used Xeon pricing reprices weekly with hyperscaler refresh cycles, so we confirm the tray or pull stock for your quantity and put a firm figure in writing with the date it holds until.
Which platforms take the Xeon Gold 6248?
It is a 2nd Gen Xeon Scalable (Cascade Lake) part on LGA3647 (Socket P), with 6-channel DDR4-2933 and PCIe 3.0, 48 lanes. It fits the server families built for that generation; the board, BIOS revision and memory population all have to match the generation, and the 6248 will not fit a socket from another generation.
What is the difference between all-core turbo and maximum turbo?
The 2.5GHz figure is the guaranteed base clock. 3.2GHz is the all-core turbo - what the part sustains when every core is loaded - and 3.9GHz is the maximum turbo on lightly loaded cores. For databases and virtualisation, the all-core figure is the one that predicts performance; the maximum turbo mostly matters for single-threaded and bursty work.
Is the Xeon Gold 6248 OEM tray or retail boxed?
Both appear on the secondary market and the condition is stated line by line before you order. This generation is overwhelmingly sold as OEM tray or as pulls from decommissioned servers; either way, the marking and sSpec are checked against your order and the unit ships with our own written warranty.
Can I mix two different Xeon models in one dual-socket server?
No. A dual-socket board needs two identical CPUs - same model and same sSpec - to train correctly. We quote matched pairs from one lot for exactly that reason.
What condition are these CPUs in, and do you ship worldwide?
Tested pulls and OEM tray stock, with the condition stated per unit before you commit and a 1-year written warranty. We ship worldwide from the Hong Kong warehouse with full export documentation, typically 3-7 days by air.
