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

Posted on

In context: Whilst Intel nonetheless instructions an enormous 90% percentage of the x86 server CPU marketplace, AMD has been gaining flooring ever since freeing its Zen-based Epyc chips. Intel hopes to position a halt to that with their upcoming Xeon Sapphire Rapids lineup, anticipated to release later this 12 months.

Intel’s subsequent era of Xeon knowledge middle processors, codenamed Sapphire Rapids, simply were given leaked. Like Intel’s client Alder Lake lineup, it’ll characteristic the chipmaker’s Golden Cove structure and Intel 7 procedure node, in the past referred to as 10 nm Enhanced SuperFin.

After a number of delays, the processors are anticipated to debut later this 12 months, round the similar time as Intel’s mainstream Raptor Lake collection. They’ll be offering as much as 56 cores and 112 threads and include a most TDP of 350W. It is price noting that the enforced BIOS energy prohibit is about at a staggering 764W, a goal it will achieve below workloads the usage of AVX-512.

As we will be able to see from the leaked screenshots, the 56-core engineering pattern options 112MB of L2 cache and 105MB of L3 cache. Intel may also release fashions with as much as 64GB of on-package HBM2e performing as an L4 cache. The leaked CPU additionally has a base clock of one.9 GHz and a three.3 GHz spice up clock, despite the fact that it could actually spice up as much as 3.7 GHz on a unmarried core. Delivery merchandise would possibly run at other frequencies, as that is best an engineering pattern.

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

Those CPUs will cross up in opposition to AMD’s Epyc 7004 (Genoa) collection, which will have to arrive round the similar time. The ones will characteristic the brand new Zen 4 structure, as much as 96 cores and 192 threads, and are going to be constructed the usage of TSMC’s 5nm node.
