Subsequent-gen Xeon CPU leaks with 56 cores and 350W TDP


In context: Whereas Intel nonetheless instructions a large 90% share of the x86 server CPU market, AMD has been gaining floor ever since releasing its Zen-based Epyc chips. Intel hopes to place a halt to that with their upcoming Xeon Sapphire Rapids lineup, anticipated to launch later this 12 months.

Intel’s subsequent era of Xeon knowledge middle processors, codenamed Sapphire Rapids, simply received leaked. Like Intel’s client Alder Lake lineup, it would function the chipmaker’s Golden Cove structure and Intel 7 course of node, beforehand referred to as 10 nm Enhanced SuperFin.

After a number of delays, the processors are anticipated to debut later this 12 months, across the identical time as Intel’s mainstream Raptor Lake collection. They’ll supply as much as 56 cores and 112 threads and include a most TDP of 350W. It is price noting that the enforced BIOS energy restrict is about at a staggering 764W, a goal it may attain below workloads utilizing AVX-512.

As we will see from the leaked screenshots, the 56-core engineering pattern options 112MB of L2 cache and 105MB of L3 cache. Intel can even launch fashions with as much as 64GB of on-package HBM2e performing as an L4 cache. The leaked CPU additionally has a base clock of 1.9 GHz and a 3.3 GHz enhance clock, though it could possibly enhance as much as 3.7 GHz on a single core. Transport merchandise would possibly run at completely different frequencies, as that is solely an engineering pattern.

This design may very well be both the Xeon Platinum 8476 or the Platinum 8480, as each are predicted to function 56 cores and 112 threads. The CPU was examined on Intel’s C741 (Emmitsburg) platform with 1TB of DDR5 reminiscence working at CL40-39-38-76 timings and assist for PCI-Specific 5.0.

These CPUs will go up in opposition to AMD’s Epyc 7004 (Genoa) collection, which ought to arrive across the identical time. These will function the brand new Zen 4 structure, as much as 96 cores and 192 threads, and are going to be constructed utilizing TSMC’s 5nm node.
