Recently, Intel they announced their new Series Max aimed at data centers. This includes Intel’s upcoming Sapphire-Rapids HEDT server CPU and the new one Xe-HPC GPU Max based. Team Blue’s new CPUs are meant to deliver 4.8x more bandwidth than the current competition.

CPU Xeon Max

Intel’s new Max CPU is a world first x86 CPU to send with high bandwidth memory. Features of the Xeon Max CPU 56 Performance cores. These cores extend 4 tiles that are connected Intel integrated multi-matrix interconnect bridge in a 350W package The Xeon Max CPU contains 64 GB of high bandwidth memory along with support for PCI Express Gen 5 i Input/Output CXL1.1.

Intel also provided some benchmarks for its upcoming Max series CPU;

  • 68% less power consumption than one AMD Milan-X cluster for the same HPCG performance.
  • AMX extensions boost AI performance and deliver up to 8x higher performance AVX-512 for INT8 with INT32 accumulation operations.
  • It offers flexibility to run on different HBM and DDR memory configurations.
  • Workload Benchmarks:
    • Climate modeling: 2.4x faster than AMD Milan-X on MPAS-A using only HBM.
    • Molecular Dynamics: In DeePMD, 2.8x improved performance compared to competing products with DDR memory.

Data Center GPU Max

After that we have Intel’s new Data Center Max GPUs. Based on the Xe-HPC architecture, they offer up to 128 Xe Cores designed specifically to handle high-speed computing. Also, we see 408 MB of L2 cache that is called the highest in the industry along with 64 MB of L1 cache memory. Best of all, these GPUs support ray tracing which can help speed up scientific visualizations.

Max GPUs will come in different form factors to suit customer needs.

  • Max Series 1100 GPU: A 300-watt double-wide PCIe card with 56 Xe cores and 48 GB of HBM2e memory. Multiple cards can be connected via Intel Xe Link bridges.
  • Max Series 1350 GPU: A 450 watt OAM module with 112 Xe cores and 96GB of HBM.
  • GPU Max Series 1550: Intel’s highest performance 600-watt OAM module with 128 Xe cores and 128GB of HBM.

In terms of performance, these GPUs offer significant performance increases compared to their competition;

  • Climate modeling: 2.4x faster than AMD Milan-X on MPAS-A using only HBM.
  • Molecular Dynamics: In DeePMD, 2.8x improved performance compared to competing products with DDR memory.

In addition to individual products, Intel also introduced a global subsystem that includes 4 OAM modules

Publication date

The Intel Max series is slated for release January 2023. The same year, the Aurora Supercomputer which is currently in production will make use of Intel’s new Max line. With the performance numbers, Intel claims this supercomputer will outperform 2 exaflops double precision maximum performance. Similarly, the Max series GPU successor codenamed “Rialto Bridgeexpected to arrive 2024.
