Intel Xeon Platinum 8460Y+ 40c/80t 2.0GHz-3.7GHz 300W (PK8071305072601)

Intel Xeon Platinum 8460Y+ Processor for High-Performance Dual-Socket Servers

The Intel Xeon Platinum 8460Y+ is a high-end 4th Gen Intel Xeon Scalable processor aimed at dense, latency-sensitive datacenter workloads where per-socket performance and memory bandwidth matter as much as core count. Built on the Sapphire Rapids platform and Intel 7 process technology, it combines 40 cores and 80 threads with a 2.0 GHz base frequency and boost clocks up to 3.7 GHz, giving a good balance between throughput and single-thread responsiveness for mixed enterprise workloads.

With 105 MB of shared L3 cache and support for up to 8 channels of DDR5 memory at up to 4800 MT/s (1DPC), the 8460Y+ is designed to keep all cores consistently fed with data, even under heavy virtualization, in-memory analytics or microservice traffic. The platform supports up to 4 TB of RAM per socket, which makes it a strong fit for large in-memory databases, real-time analytics engines and big SAP or ERP deployments that need both capacity and bandwidth rather than just raw core counts.

On the I/O side, the CPU exposes 80 PCI Express 5.0 lanes per socket, enabling dense attachment of NVMe SSDs, NICs and accelerators without over-subscribing the PCIe fabric. Combined with four UPI links at 16 GT/s and 2-socket scalability, it allows you to build balanced dual-socket systems where storage, networking and compute scale together instead of bottlenecking on an older PCIe generation or limited lane budget. This is especially relevant for modern cloud-native clusters and NVMe-over-Fabrics backends that generate a lot of I/O per core.

A key differentiator of Sapphire Rapids is the set of built-in accelerators, and the 8460Y+ fully participates in that story. It supports Intel QuickAssist Technology (QAT) for offloading compression and cryptography, Intel Data Streaming Accelerator (DSA) for high-throughput data movement, Dynamic Load Balancer (DLB) to optimize packet scheduling and In-Memory Analytics Accelerator (IAA) for analytics-style workloads. Together with Intel Deep Learning Boost and AMX matrix extensions, these features allow certain network, storage, security and AI tasks to be pushed onto dedicated engines instead of consuming scalar CPU cores, improving effective throughput per watt when the software stack is tuned for them.

The 300 W TDP reflects that this is a performance-focused part rather than an efficiency SKU, but Intel Speed Select Technology gives operators some control over how that power budget is allocated. The chip can run in different performance profiles that adjust the number of active cores and base frequency while staying within the same 300 W envelope, so you can prioritize higher clocks on fewer cores for latency-critical services or keep all 40 cores active for heavy batch processing. This flexibility is useful in environments where the same hardware must handle both interactive and offline workloads over its lifecycle.

In the broader 4th Gen Xeon Platinum stack, the 8460Y+ sits as a strong option for operators who want more throughput than 32-core models but do not need the extreme core counts and higher power envelopes of the largest 56- or 60-core parts. It targets dual-socket servers in roles such as virtualization clusters, high-traffic databases, large Java or .NET application farms, as well as HPC and analytics jobs that benefit from high memory bandwidth and strong per-socket performance. For buyers planning to standardize on Sapphire Rapids, the 8460Y+ is a practical choice when you need a performance-oriented, accelerator-aware CPU that can be deployed broadly in the fleet without jumping to the very top of the product stack.
