The next-gen Xeon CPU features 56 cores and a 350W TDP: Leaks

The next-gen Xeon CPU has been leaked and it features 56 cores and a 350W TDP. While Intel currently holds a commanding 90% share of the x86 server CPU market, AMD has been steadily gaining ground since its Zen-based Epyc CPUs release. With their next Xeon Sapphire Rapids series, which is anticipated to arrive later this year, Intel aims to put an end to this.
Sapphire Rapids, Intel’s next-gen Xeon CPU, leaked. It will use Intel‘s Golden Cove architecture and Intel 7 process node, formerly known as 10 nm Enhanced SuperFin, just like Intel’s consumer Alder Lake series.
After many delays, the chips are slated to appear later this year, around the same time as Intel’s mainstream Raptor Lake series. They’ll have up to 56 cores and 112 threads, with a maximum TDP of 350 watts. It’s worth mentioning that the BIOS power limit is set at a whopping 764W, which it may approach under AVX-512 workloads.

The 56-core engineering sample, as seen in the leaked screenshots, has 112MB of L2 cache and 105MB of L3 cache. Models with up to 64GB of on-package HBM2e functioning as an L4 cache will also be available from Intel. The disclosed CPU also has a 1.9 GHz base clock and a 3.3 GHz boost clock, with a single-core boost frequency of 3.7 GHz. Because this is simply an engineering sample, shipping goods may run at various frequencies.
The Xeon Platinum 8476 or the Platinum 8480 could represent this architecture, as both are expected to have 56 cores and 112 threads. The CPU was tested with 1TB of DDR5 memory running at CL40-39-38-76 timings and PCI-Express 5.0 functionality on Intel’s C741 (Emmitsburg) platform.

Expanding the Intel Xeon Processor Road Map
These processors will compete with AMD’s Epyc 7004 (Genoa) family, which is expected to be released around the same time. These will be produced on TSMC’s 5nm node and will employ the new Zen 4 architecture with up to 96 cores and 192 threads.
