Xeon Gold 6148 vs Xeon Gold 6240
The Xeon Gold 6148 and the Xeon Gold 6240 are both server processors we supply tested from Hong Kong, and the figures below are the same ones published on each product page. They share 5 listed specification rows and separate on cores / threads, cache, memory, so the decision is less about "which is better" and more about which of those differences your platform or workload can actually use.
Nothing on this page is a price: component pricing moved too fast in 2026 for a printed figure to stay honest, so both are quoted on request against confirmed stock with the date the quote holds until. If you are replacing a part, send the platform and we will confirm the population before you commit.

Decision
Which one to buy
For processors the useful split is throughput versus frequency. More cores per socket wins on virtualisation density, parallel batch work and multi-tenant hosting, where the scheduler can keep every core busy; higher base and boost clocks win where the workload is latency-sensitive or licensed per core, and the extra cores would sit idle. Check the socket and the platform's memory generation before anything else: a CPU is only useful in a board that takes it, and the two models above are interchangeable only when the socket matches. TDP also sets the cooling and power budget per node.
Choose the Xeon Gold 6148 if

- ·You need more cache — the Xeon Gold 6148 lists 20MB L2 + 27.5MB L3 against 18MB L2 + 24.75MB L3 on the Xeon Gold 6240.
- ·Memory: 6-channel DDR4-2666, ECC
Choose the Xeon Gold 6240 if
- ·Memory: 6-channel DDR4-2933, ECC
- ·Turbo (all-core / max): 3.3GHz / 3.9GHz
- ·Launch: April 2019

Frequently asked questions
How much do the Xeon Gold 6148 and the Xeon Gold 6240 cost?
We do not publish prices for either: DRAM and CPU pricing moved too fast in 2026 for a printed figure to stay honest. Send the quantity, the platform and the condition you want and we quote both against confirmed stock, with the date the figure holds until.
What is the main difference between the Xeon Gold 6148 and the Xeon Gold 6240?
Cores / Threads (Xeon Gold 6148: 20 cores / 40 threads; Xeon Gold 6240: 18 cores / 36 threads); Cache (Xeon Gold 6148: 20MB L2 + 27.5MB L3; Xeon Gold 6240: 18MB L2 + 24.75MB L3); Memory (Xeon Gold 6148: 6-channel DDR4-2666, ECC; Xeon Gold 6240: 6-channel DDR4-2933, ECC).
Can I use the Xeon Gold 6148 and the Xeon Gold 6240 in the same system?
Both are LGA3647 (Socket P) parts, so one server can take either model — but you would not mix two different CPU models in a single two-socket machine; order one model per server.
Which one should I buy?
Buy the one whose strong points match the job: see the "Choose" section above. If you are replacing an existing part, send the platform or the old part number and we will confirm compatibility before you order.
What condition are they in, and do you ship worldwide?
Both are supplied tested with a 1-year written warranty. Condition is stated line by line before you order — new, decommissioned pull or OEM tray — and we ship worldwide from the Hong Kong warehouse with full export documentation, typically 3–7 days by air.
