Intel Xeon Gold 6000 (5th Gen) 6548N Dotriaconta-core (32 Core) 2.80 GHz Processor
Dotriaconta-Core:
Inside the Xeon Gold 6548N
Intel’s 32-core, 250 watt data-center processor trades peak frequency for density and per-socket memory bandwidth — built for network, storage, and multi-cloud workloads that need cores more than clock speed.
Somewhere in Intel’s naming conventions there’s a habit of reaching for Greek and Latin numerals instead of just writing the number — and “dotriaconta,” Greek for thirty-two, is how the Xeon Gold 6548N ended up branded as a dotriaconta-core processor. Strip away the vocabulary and it’s a fairly straightforward proposition: 32 Emerald Rapids cores, 64 threads, and a memory subsystem tuned for the kind of steady, high-throughput workloads that fill modern data centers.
What’s actually inside // architecture
The 6548N belongs to Intel’s 5th Gen Xeon Scalable family, code-named Emerald Rapids, fabricated on the Intel 7 process. It’s a monolithic-feeling successor to Sapphire Rapids that leans on architectural refinement rather than a node shrink — larger last-level cache, tightened core-to-core latency, and the same built-in AI acceleration engines (AMX, DL Boost) that the Gold and Platinum tiers now share across the board.

| Scalability | 2-socket (2S) |
Built around memory bandwidth // platform
The “N” suffix in Intel’s 5th Gen lineup marks a network- and edge-optimized SKU, and the spec sheet backs that up: 8 memory channels feeding up to 4 TB of DDR5 at up to 5200 MT/s, and 80 lanes of PCIe 5.0 for NICs, NVMe, and accelerators. For workloads bottlenecked on bytes moved rather than instructions retired — packet processing, storage gateways, in-memory caching — that channel count matters more than another few hundred megahertz.
- MEM 8-channel DDR5-5200, up to 4 TB per socket
- I/O 80 lanes PCIe 5.0, CXL 1.1 Type 3 support
- AI Intel AMX and DL Boost built into every core
- SEC Intel TXT, TME, and SGX enclave support
- RAS Intel Speed Select Technology (SST-PP) for per-core profile tuning
Why 250 W matters: the 6548N sits in the same power envelope as parts with fewer cores and higher clocks. Intel’s pitch is that consistent all-core throughput at 2.8 GHz base beats chasing turbo peaks in workloads that are already thread-saturated — think web tier fleets, virtualization hosts, and CDN edge nodes running thousands of light, parallel connections.
Where it sits in the stack // comparison
Within the same 32-core, 60 MB cache class, Intel offers several variants tuned for different priorities. The 6548N gives up clock speed and cache-per-dollar for a lower list price and the “N” networking-oriented feature set:
| Model | Base clock | TDP | Focus |
|---|---|---|---|
| 6548N | 2.8 GHz | 250 W | Network / edge, memory bandwidth |
| 6538Y+ | 2.2 GHz | 225 W | Balanced, lower power |
| 6548Y+ | 2.5 GHz | 250 W | General purpose, higher clocks |
| 6542Y | 2.9 GHz | 250 W | Fewer cores (24), higher frequency |
The bottom line // takeaway
The Xeon Gold 6548N isn’t chasing single-thread records — it’s a socket built to keep 64 threads fed with data. For infrastructure teams sizing dual-socket nodes for storage, virtualization, or telco/network functions, the combination of 8-channel DDR5, 80 PCIe 5.0 lanes, and a moderate 250 W envelope makes it one of the more balanced picks in Intel’s 5th Gen Gold tier, even if the name is a mouthful.
