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

In context: While Intel restful commands a enormous 90% share of the x86 server CPU market, AMD has been gaining ground ever since releasing its Zen-essentially based mostly Epyc chips. Intel hopes to construct a slay to that with their upcoming Xeon Sapphire Rapids lineup, anticipated to birth later this year.

Intel’s subsequent expertise of Xeon records center processors, codenamed Sapphire Rapids, excellent got leaked. Love Intel’s client Alder Lake lineup, it is going to characteristic the chipmaker’s Golden Cove structure and Intel 7 course of node, previously identified as 10 nm Enhanced SuperFin.

After several delays, the processors are anticipated to debut later this year, across the identical time as Intel’s mainstream Raptor Lake series. They’re going to offer up to 56 cores and 112 threads and come with a most TDP of 350W. Or not it’s price noting that the enforced BIOS energy restrict is determined at a staggering 764W, a target it would possibly presumably per chance per chance reach below workloads the usage of AVX-512.

As we can seek for from the leaked screenshots, the 56-core engineering pattern aspects 112MB of L2 cache and 105MB of L3 cache. Intel can even birth models with up to 64GB of on-bundle HBM2e performing as an L4 cache. The leaked CPU also has a inappropriate clock of 1.9 GHz and a 3.3 GHz boost clock, even supposing it will speed to three.7 GHz on a single core. Shipping merchandise would possibly presumably per chance per chance bustle at diverse frequencies, as that is easiest an engineering pattern.

This blueprint would possibly presumably per chance per chance presumably be both the Xeon Platinum 8476 or the Platinum 8480, as each and every are predicted to characteristic 56 cores and 112 threads. The CPU used to be tested on Intel’s C741 (Emmitsburg) platform with 1TB of DDR5 memory working at CL40-39-38-76 timings and abet for PCI-Notify 5.0.

These CPUs will lumber up against AMD’s Epyc 7004 (Genoa) series, which would possibly maybe beget to restful advance across the identical time. Those will characteristic the restful Zen 4 structure, up to 96 cores and 192 threads, and are going to be constructed the usage of TSMC’s 5nm node.
