The CPU That Sits at the Top of Every Dell R760, R860, and xFusion 2488H V7 Configuration

When an IT director says “give me the fastest option,” this is the processor that goes into the quote. The Intel Xeon Platinum 8480+ is a 56-core, 112-실, 4th Gen Xeon Scalable processor with a 350W TDP — the top-bin CPU for dual-socket platforms like the Dell R760 and R770, and one of four identical CPUs in the Dell R860. It is not the most cost-effective Xeon. It is the one you order when the workload demands it.

On-Die Accelerators — The Feature That Separates 4th Gen from 3rd Gen

그만큼 8480+ includes four Intel on-die accelerators that previous-generation Xeons lacked. DSA (Data Streaming Accelerator) offloads memory copy, CRC, and data movement operations from CPU cores — reducing CPU utilization by 20-30% on storage and networking I/O-heavy workloads. IAA (In-Memory Analytics Accelerator) accelerates database compression and decompression for Oracle, SQL 서버, and PostgreSQL. DLB (Dynamic Load Balancer) improves packet processing for NFV and software-defined networking. QAT (QuickAssist Technology) accelerates cryptographic operations — TLS, IPsec, and compression — at line rate without consuming CPU cores. If your workload is I/O-bound, these accelerators deliver more performance uplift than an extra 4 cores would.

Compatible Server Platforms

LGA 4677 socket. Compatible with Dell PowerEdge R660, R760, R770, R860, R960 (4th Gen Xeon platforms). Not compatible with 14th Gen (R640, R740) or 15th Gen (R650, R750) — those use LGA 3647 and LGA 4189 각기. Also compatible with xFusion FusionServer V7 series. Verify platform TDP support — the 8480+ at 350W requires a server chassis rated for 350W+ processor TDP. Dell R760, R770, R860 support this. R660 may require a higher-TDP heatsink option.
