Intel unveiled three new additions to its Intel® Xeon® 6 series of central processing units (CPUs), designed specifically to manage the most advanced graphics processing unit (GPU)-powered AI systems. These new processors with Performance-cores (P-cores) include Intel’s innovative Priority Core Turbo (PCT) technology and Intel® Speed Select Technology – Turbo Frequency (Intel® SST-TF), delivering customizable CPU core frequencies to boost GPU performance across demanding AI workloads.

The new Xeon 6 processors are available today, with one of the three currently serving as the host CPU for the NVIDIA DGX B300, the company’s latest generation of AI-accelerated systems. The NVIDIA DGX B300 integrates the Intel® Xeon® 6776P processor, which plays a vital role in managing, orchestrating and supporting the AI-accelerated system. With robust memory capacity and bandwidth, the Xeon 6776P supports the growing needs of AI models and datasets.

“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.”

Maximizing AI Performance with Priority Core Turbo
The introduction of PCT, paired with Intel SST-TF, marks a significant leap forward in AI system performance. PCT allows for dynamic prioritization of high-priority cores, enabling them to run at higher turbo frequencies. In parallel, lower-priority cores operate at base frequency, ensuring optimal distribution of CPU resources. This capability is critical for AI workloads that demand sequential or serial processing, feeding GPUs faster and improving overall system efficiency.

Looking more broadly, Intel Xeon 6 processors with P-cores deliver industry-leading features for any AI system, including:

High Core Counts and Exceptional Single-Threaded Performance: With up to 128 P-cores per CPU, these processors ensure balanced workload distribution for intensive AI tasks.
30% Faster Memory Speeds1: When compared to the competition, Intel Xeon 6 offers superior memory performance at high-capacity configurations and supports leading-edge memory bandwidth with MRDIMMs and Compute Express Link.
Enhanced I/O Performance: With up to 20% more PCIe lanes than previous Xeon processors, these CPUs enable faster data transfer for I/O-intensive workloads.
Unmatched Reliability and Serviceability: These processors are built for maximum uptime with robust reliability, availability and serviceability features that minimize business disruptions.
Intel® Advanced Matrix Extensions: These CPUs support FP16 precision arithmetic, enabling efficient data preprocessing and critical CPU tasks in AI workloads.
As enterprises modernize their infrastructure to handle the increasing demands of AI, Intel Xeon 6 processors with P-cores provide the ideal combination of performance and energy efficiency. These processors support a wide range of data center and network applications, solidifying Intel’s position as the leader in AI-optimized CPU solutions.
