Product overview
Intel lists SRF81 as an Xeon Platinum 8273CL 28-Core 2.20Ghz 38.5MB Processor. Licensing is often counted per core, so the cheapest chip that fits the socket is not always the cheapest chip to run. This part is 28-core. Tell us what the host is licensed for and we will factor that into the recommendation.
Quote requests are answered within 48 business hours, with availability confirmed before you raise a purchase order rather than after.

Where the Intel SRF81 is deployed
- Sourcing SRF81 against a build sheet that names it explicitly
- Upgrading compute in place rather than replacing the chassis
- Populating the second socket on a single-CPU server
Who this part is for
- Organisations consolidating licences onto fewer, larger cores
- Teams upgrading compute inside an existing chassis rather than replacing it
- Engineers matching a second socket to the processor already fitted
What you get ordering this from us
Ordered by part number
SRF81 is what is quoted and SRF81 is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.
Volume pricing
The listed price is per unit; tiered pricing applies at quantity and purchase orders are accepted.
Questions buyers ask about this part
Is SRF81 genuine and is the warranty intact?
Yes. Supplied new and unopened, so the manufacturer warranty and firmware update path stay supported. No grey-market stock and no refurbished units sold as new.
Will SRF81 work in my server?
Send the service tag. We check the platform's supported-CPU list and the BIOS revision it requires, and where the board is dual-socket we confirm what is in the other socket. A stepping the firmware does not recognise will not post.
Do you accept purchase orders and quote at volume?
Yes, POs from qualified organisations, net terms on approval, and banded pricing once the quantity is worth banding. Send the number and we will price it properly.

Specifying a system, not just the part?
On a training or inference node the host CPU is sized around the accelerators it feeds, not chosen on its own.
