Maximum Performance with Next-Generation Industry Standard Technologies


High Bandwidth Memory

Up to 4x more memory bandwidth, providing a generational performance improvement of up to 2.8x over 3rd Gen Intel Xeon Scalable processors with 2 to 3 times performance increases across different workloads.

Anewtech-Systems-GPU-Server-Supermicro-AI-server-intel-servers-PCIe5PCIe 5.0

Double the I/O bandwidth compared to previous generation PCIe 4.0. At 32G, next-generation PCIe 5.0 not only helps today’s applications run faster – it also enables new applications in AI/ML and cloud computing.



Delivers a significant benefit to Intel-based platforms with over two times the performance of DDR4, and capacities as high as 512GB.
