The 32-Core CPU That Fills the Gap Between Budget Silver and Overkill Platinum

Between the 12-core Silver 4410Y at the bottom of the Xeon stack and the 56-core Platinum 8480+ at the top sits the Gold 6548Y: 32 コア, 64 スレッド, 4.1 GHz max turbo, 250W TDP. It is the CPU that most IT teams should be ordering for general-purpose virtualization, mid-tier databases, and consolidated workloads — but most order the Silver to save money and end up CPU-bound, or order the Platinum to be safe and end up paying for idle cores. The Gold 6548Y is the Goldilocks processor: enough cores for 100+ VMs per dual-socket node, high enough single-thread speed for databases, and a price point that sits at roughly 40 percent of the Platinum 8480+.

6548Y vs 4410Y vs 8480+ — The Core Tier Decision

特徴	Silver 4410Y	Gold 6548Y	白金 8480+
コア / Threads	12 / 24	32 / 64	56 / 112
Base / Turbo	2.0 / 3.9 GHz	2.5 / 4.1 GHz	2.0 / 3.8 GHz
TDP	150W	250W	350W
Memory Speed	DDR5-4000	DDR5-5200	DDR5-4800
UPI Links	2バツ	3バツ	4バツ
Best For	AD, file, print, 角	仮想化, データベース, consolidation	Maximum core density, VDI, HPC
Relative Price (per CPU)	~25 percent	100 percent (baseline)	~200 percent

Two critical data points: the 6548Y runs DDR5-5200 — 8 percent faster than the 8480+’s DDR5-4800 — and its 3.4 GHz all-core turbo beats the 8480+’s 2.6 GHz by 30 percent. For memory-bandwidth-sensitive workloads (データベース, VDI boot storms) and single-thread-sensitive workloads, the 6548Y outperforms the more expensive Platinum on both metrics. The 8480+ wins only on raw core count.
