Xeon Gold 5218R - 20-Core Cascade Lake
20 cores / 40 threads, 2.10GHz base and 4.00GHz maximum turbo, 27.5MB cache, 125W TDP on FCLGA3647, sSpec SRGZ7 at stepping B1, tray ordering code CD8069504446300. Six DDR4-2667 memory channels up to 1TB per socket, 48 PCIe 3.0 lanes and Intel AVX-512. These are the published Intel ARK figures for the Xeon Gold 5218R, part of the 2nd Gen Xeon Scalable family launched Q1'20.
FCLGA3647 Socket Class
FCLGA3647 is the socket introduced with the 1st Gen Xeon Scalable parts and carried through Cascade Lake, so boards built for Skylake-SP generally accept a 5218R after a firmware update - which is the migration this part is usually bought for. Board and BIOS support is confirmed against your platform's supported-CPU list before we quote, not assumed from the socket alone.

The 5218R is the value pick of the Cascade Lake Gold range for anyone already sitting on FCLGA3647 hardware: 20 cores, a 4.00GHz turbo ceiling that keeps lightly-threaded work responsive, and AVX-512 for vector-heavy workloads - all on a socket that 1st Gen Xeon Scalable boards generally accept after a firmware update, which means the upgrade can be a CPU swap rather than a platform replacement.
What it is not is a current-generation part. Intel's servicing status for this processor number is ESU Notification Issued, so plan for a defined servicing horizon rather than indefinite microcode coverage; if that matters for your workload, the newer Xeon Gold 6530 is the 32-core Emerald Rapids alternative on LGA4677, at the cost of a new board and DDR5. Full range: Intel server CPUs.
Transparent Pricing
2026 Reference Pricing by Configuration
We do not publish a price for this part. Intel's list reference is $1483.00-$1493.00, a recommended customer price from the part's launch period rather than a 2026 market figure, and we will not present it as a quote. Pricing is built from the pulls and tray stock we can confirm for your quantity, and condition is verified against the physical marking rather than assumed from the model number.
Tested Server Pulls
On Request
Decommissioned-server pulls, individually tested with the diagnostic result recorded against the unit. Cascade Lake parts are now leaving service in volume, so supply is good but batch condition varies - which is exactly why each unit is tested rather than graded by model number.
Matched Pairs
On Request
Matched-stepping pairs for dual-socket FCLGA3647 boards, so a 2P system is not assembled from unrelated lots. Tell us your board and firmware level.
Volume Orders (10+ units)
On Request
Multi-unit and repeat orders are quoted against live inventory, with freight consolidated from our Hong Kong warehouse.
No price is published for this SKU: we quote against confirmed stock rather than reprinting a launch-period Intel list price. Intel's only published figure is a recommended customer price of $1483.00-$1493.00, shown in the specification table for reference. Send us quantity and board model for a firm quote.

Quality Process
What We Check Before a Xeon Gold 5218R Ships
Model String and sSpec Verification
Heat-spreader marking and sSpec are read under magnification and checked against the exact processor number on your order. Cascade Lake Gold parts share one socket across many core counts, so the marking is the only reliable identifier.
FCLGA3647 Pad Inspection
Processor-side contact pads are inspected under magnification for contamination, corrosion and rework marks - the most common reason a pulled Scalable CPU is rejected.
POST and 20-Core Enumeration
Full 20-core / 40-thread POST on a reference FCLGA3647 board, with every core enumerated so nothing is silently dead.
Six-Channel Memory Validation
All six DDR4-2667 channels are exercised on the reference platform. A CPU that posts but drops a channel is not shippable, and on a six-channel part that loss is significant.
BIOS and Microcode Matching
For 1st Gen Scalable board upgrades we check the BIOS level your board needs for a Cascade Lake part and flag it before shipping, because this is the step that most often turns a CPU swap into a support call.
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 an Intel Xeon Gold 5218R cost in 2026?
We quote it against confirmed stock. Intel's recommended customer price is $1483.00-$1493.00, a launch-period list reference rather than a 2026 market price for a decommissioned pull. Send us quantity and board model for a firm quote.
What is the difference between the Xeon Gold 5218R and the Xeon Gold 6530?
They are two platforms apart. The 5218R is Cascade Lake: 20 cores / 40 threads, 2.10GHz base and 4.00GHz turbo, 27.5MB cache, 125W, six DDR4-2667 channels, 48 PCIe 3.0 lanes and AVX-512 on FCLGA3647, launched Q1'20, with Intel servicing status ESU Notification Issued. The 6530 is Emerald Rapids: 32 cores / 64 threads, 160MB cache, 270W, eight DDR5-4800 channels, 80 PCIe 5.0 lanes and AMX on LGA4677, launched Q4'23. The 6530 gives you 60% more cores, roughly six times the cache, DDR5 bandwidth and PCIe 5.0 - but it needs a new board and new memory. If your FCLGA3647 platform still has headroom, the 5218R is the cheaper way to more cores; if you are building fresh, going to the 6530 avoids paying twice.
Will a Xeon Gold 5218R work in my existing 1st Gen Scalable board?
Often yes, and it is the single most important thing to check before buying. Cascade Lake uses the same FCLGA3647 socket as Skylake-SP, so many 1st Gen boards accept a 5218R after a BIOS or firmware update - but the requirement is board-specific and some vendors never validated Cascade Lake on earlier models. Tell us your exact board and current BIOS level and we will confirm against the vendor's supported-CPU list rather than guessing from the socket.
What condition are these CPUs in, and what warranty applies?
Units are decommissioned server pulls and residual tray stock: marking and sSpec verified against your order, FCLGA3647 pads inspected under magnification, full 20-core POST with all six memory channels exercised, and thermal behaviour logged. Each CPU ships with its diagnostic record and a 1-year warranty.
Can you ship the Xeon Gold 5218R worldwide from Hong Kong?
Yes. We ship worldwide from our Hong Kong warehouse with full export documentation, and express air freight typically arrives in 3 to 7 days to major markets. For volume or multi-SKU orders we consolidate freight with memory, storage and chassis to reduce the per-unit cost.
