Intel’s Xeon Phi series with up to 72 CPU cores and HBM1 memory

Intel’s new Xeon Phi 7290 is the fastest processor that Intel has ever made, and it’s also their most expensive as well. The new Xeon Phi 7290 has 72 processing cores clocked at 1.5GHz each and requires 245W of power + 15W fabric. The Xeon Phi 7290 will be available in September, with a huge price tag of $6294. This new Xeon Phi doesn’t rely on the PCIe bus, allowing support for a wider variety of workloads, and configurations that aren’t supported by usual accelerators.

The Xeon Phi 7290 also packs 16GB of HBM, which offers 490GB/sec of memory bandwidth for applications that are memory bound, while the dual-port Intel Omni-Path Fabric makes an appearance, reducing the cost of Intel’s new Xeon Phi 7290, regarding cost, power consumption and space required. The new Xeon Phi 7290 is one of four new processors, with the new chips packaged very similar to video cards, functioning as primary processors, or co-processors – depending on the use.

The second in line is Xeon Phi 7250 with 68 processors core clocked at 1.4GHz, the same 16GB of HBM1 with 7.2GT/s bandwidth and 384GB of RAM support at 2400MHz.

The third one is the Xeon Phi 7230 which has 64 processor cores at 1.3GHz, and the last one is Xeon Phi 7210 represents the best value for money with 64 cores at 1.3GHz with 16GB of HBM1 6.4GT/s bandwidth and 384GB of RAM support at 2133MHz. All four Xeon Phi processors have 245W + 15W fabric power requirements.


Intel’s new Xeon Phi processors features:

  • Connectivity: Intel Xeon Phi processors now offer the ability to deploy Intel’s next generation fabric architecture, Intel Omni-Path, as a standard, integrated option. The combination provides the foundation for powerful and efficient data traffic control by using an advanced “on-load” design that cost-effectively maximizes performance.

  • Intel Omni-Path Architecture automatically scales to tens of thousands of nodes with extremely low power consumption, making the solution ideal for increasingly demanding HPC and analytics workloads.

  • Storage: Intel Solutions for Lustre software is a parallel filesystem purpose-built for HPC to provide fast, “massively scalable storage software” for accelerating performance on complex workloads.

  • Memory: MCDRAM is the integrated memory on Intel Xeon Phi processors, providing up to 5x the bandwidth of DDR4 to deliver breakthrough performance for memory-bound workloads.

  • Software: Intel HPC Orchestrator simplifies the complexity of installation, configuration and ongoing maintenance of implementing an HPC software stack.
