44-core Xeon for single-socket servers
The Intel Xeon Platinum 8458P is a 44-core, 88-thread server processor built on 10 nm Sapphire Rapids silicon. It targets single-socket platforms that need high core density and large memory capacity for virtualisation, database and high-performance computing workloads.
82.5 MB L3 cache and DDR5-4800 bandwidth
Eight memory channels support up to 4 TB of DDR5 at 4800 MT/s with one DIMM per channel or 4400 MT/s with two. The 82.5 MB shared L3 cache feeds all 44 cores, reducing latency for memory-bound tasks while the 3.8 GHz max turbo frequency handles bursty single-thread demand.
LGA 4677 socket with 80 PCIe 5.0 lanes
The processor drops into an LGA 4677 socket and exposes 80 lanes of PCI Express 5.0 for fast storage, networking or accelerator cards. A 350 W thermal design power requires substantial cooling, which is not included. Scalability is limited to one socket, so dual-socket builds are not supported.

คำถามเกี่ยวกับสินค้านี้
Can I keep using my current DDR5 4800 MT/s RDIMMs with the 8-channel controller on this Xeon Platinum 8458P?
Yes, the integrated memory controller supports up to DDR5 4800 MT/s at 1 DPC and 4400 MT/s at 2 DPC across eight channels, so existing DDR5 4800 modules will run at their rated speed.
How do I verify the 44 cores and 88 threads are active after installing the processor?
Check the OS task manager or run lscpu; you should see 44 physical cores, 88 logical processors, a base frequency of 2.7 GHz and a maximum turbo of 3.8 GHz.
Does the box contain a heatsink or do I need to buy a 350 W cooler separately?
The processor is sold without a cooling device; you must source a compatible LGA 4677 cooler rated for at least 350 W TDP.
