Intel has unveiled three new additions to its Xeon 6 series of CPUs designed to work alongside GPU-powered AI systems. These processors feature the new Priority Core Turbo (PCT) technology and Intel Speed Select Technology – Turbo Frequency (SST-TF).
The Intel Xeon 6776P is serving as the host CPU for the NVIDIA DGX B300, the brand’s latest generation of AI-accelerated systems. With its higher memory capacity and bandwidth, the Xeon processor manages and supports NVIDIA’s new AI system, the DGX B300.
“These new Xeon SKUs demonstrate the unmatched performance of Intel Xeon 6, making it the ideal CPU for next-gen GPU-accelerated AI systems,” said Karin Eibschitz Segal, corporate vice president and interim general manager of the Data Center Group at Intel. “We’re thrilled to deepen our collaboration with NVIDIA to deliver one of the industry’s highest-performing AI systems, helping accelerate AI adoption across industries.”
Intel Priority Core Turbo Technology
The PCT (Priority Core Turbo) technology is part of Intel’s broader Speed Select technology. This allows the selected core, also known as the high-priority core, to run at a higher frequency or clock speed. Meanwhile, the lower-priority cores operate at a base frequency. This design claims to ensure optimal distribution of CPU resources.
The new Intel Xeon processors offer up to 128 P-Cores. The brand also claims that the new processors offer up to 30 percent faster memory performance as compared to the competition, with support for MRDIMM memory (Multiplexed Rank DIMMs). When compared to previous-gen processors, Xeon 6 promises 20 percent more PCIe lanes for faster data transfer rates with I/O-intensive workloads.
These CPUs also support FP16 precision arithmetic, enabling efficient data preprocessing and critical CPU tasks in AI workloads. Essentially, by offloading select operations to the CPU, systems can reduce latency and improve efficiency when handling mixed workloads.
