At the recently held Supercomputing 2021 event, intel gave a brief session where the chip discussed its next-generation data centre roadmap and also talked about its upcoming Ponte Vecchio GPUs & the Sapphire Rapids-SP Xeon CPUs.
The company has already revealed much of the technical details regarding its next-gen data centre CPU & GPU lineup at Hot Chips 33 and at SC21, Intel re-iterated what it has already said and also revealed a few more tidbits at SuperComputing 21.
The current generation of Intel Xeon Scalable processors has been extensively adopted by our HPC ecosystem partners, and we are adding new capabilities with Sapphire Rapids – our next-generation Xeon Scalable processor that is currently sampling with customers. This next-generation platform delivers multi-capabilities for the HPC ecosystem, bringing for the first time in-package high bandwidth memory with HBM2e that leverages the Sapphire Rapids multi-tile architecture. Sapphire Rapids also brings enhanced performance, new accelerators, PCIe Gen 5, and other exciting capabilities optimized for AI, data analytics, and HPC workloads.
HPC workloads are evolving rapidly. They are becoming more diverse and specialized, requiring a mix of heterogeneous architectures. While the x86 architecture continues to be the workhorse for scalar workloads, if we are to deliver orders-of-magnitude performance gains and move beyond the exascale era, we must critically look at how HPC workloads are run within the vector, matrix, and spatial architectures, and we must ensure these architectures seamlessly work together. Intel has adopted an “entire workload” strategy, where workload-specific accelerators and graphics processing units (GPU) can seamlessly work with central processing units (CPU) from both hardware and software perspectives.
We are deploying this strategy with our next-generation Intel Xeon Scalable processors and Intel Xe HPC GPUs (code-named “Ponte Vecchio”) that will power the 2 exaflop Aurora supercomputer at Argonne National Laboratory. Ponte Vecchio has the highest compute density per socket and per node, packing 47 tiles with our advanced packaging technologies: EMIB and Foveros. There are over 100 HPC applications running on Ponte Vecchio. We are also working with partners and customers including – ATOS, Dell, HPE, Lenovo, Inspur, Quanta, and Supermicro – to deploy Ponte Vecchio in their latest supercomputers.
First coming to the Sapphire Rapids-SP and the processors will be coming in two package variants, a standard, and an HBM configuration. Firstly the standard variant will be featuring a chipset design that is composed of four CXC dies featuring a die size of around 400mm2.
The four HBM2E memory packages will feature 8-Hi stacks so Intel is going for at least 16 GB of HBM2E memory per stack for a total of 64 GB across the Sapphire Rapids-SP package.
- Intel Sapphire Rapids-SP Xeon (Standard Package) – 4446mm2
- Intel Sapphire Rapids-SP Xeon (HBM2E Package) – 5700mm2
- AMD EPYC Genoa (12 CCD Package) – 5428mm2

Secondly, we have the Ponte Vecchio, and the chip maker outlined some key features of its flagship data centre GPU such as 128 Xe cores, 128 RT units, HBM2e memory, and a total of 8 Xe-HPC GPUs which all will be connected.
This chip will be featuring up to 408 MB of L2 cache in two separate stacks that will connect via the EMIB interconnect. This flagship from intel will also be featuring multiple dies based on Intel’s own ‘Intel 7’ process and TSMC’s N7 / N5 process nodes.
Intel also has several next-generation solutions for advanced packaging designs such as Forveros Omni and Forveros Direct as they enter the Angstrom Era of transistor development.
