Intel® Xeon® CPU Max 9480: The High-Bandwidth Sovereignty

Architectural Overview: The HBM2e Advantage

The Xeon® Max 9480 is the pinnacle of Intel’s "Max" series. While it shares the Sapphire Rapids foundation with the Platinum 8490H, it adds 64GB of on-package HBM2e memory. This creates a massive, low-latency data pool that sits directly next to the compute tiles, delivering up to 1 TB/s of memory bandwidth—over 3x the bandwidth of standard 8-channel DDR5.

The Core Specifications

• Total Cores/Threads: 56 / 112

• Max Turbo Frequency: 3.50 GHz

• On-Package HBM2e: 64 GB

• L3 Cache: 112.5 MB

• TDP: 350W

• PCIe Topology: 80 Lanes of PCIe 5.0

The Ultimate Performance CPU: Why the 9480 Dominates

1. The Three Operational Modes (The "Enigma" Flex)

The 9480 is the only CPU that allows you to architect your memory topology at the hardware level:

• HBM-Only Mode: Boot the system with zero DDR5 installed. For workloads under 64GB, the system runs entirely on HBM2e, eliminating the latency and power draw of external DIMMs.

• Flat Mode: The 64GB HBM2e and your DDR5 act as two separate pools. You can pin mission-critical datasets (like a bank’s transaction ledger) specifically to the HBM for zero-wait-state processing.

• Cache Mode: The 64GB of HBM2e acts as a massive L4 cache for the DDR5, automatically accelerating any workload that exceeds the HBM capacity.

2. Destroying the "Memory Wall"

Traditional CPUs are often "starved" for data; the cores are faster than the RAM can feed them. The 9480 solves this. In memory-bound applications like Fluid Dynamics (CFD), Financial Modeling, and Weather Prediction, the 9480 can deliver up to 4.8x the performance of standard enterprise chips.

3. EMIB Multi-Die Interconnect

The 9480 uses Intel’s Embedded Multi-Die Interconnect Bridge (EMIB) to link four compute tiles and four HBM2e stacks. This ensures that every core has high-speed, uniform access to the entire 64GB HBM pool, maintaining architectural symmetry that monolithic chips can’t match.

4. Acceleration without Abstraction

Like the 8490H, the 9480 includes 4 default Intel® Data Streaming Accelerators (DSA). When paired with the HBM2e, the 9480 can move data across the system with virtually zero CPU overhead, making it the most efficient "Data Engine" ever built for the FCLGA4677 socket.

The Cosmic Spark Value Proposition

While the global MSRP sits at $12,980, Cosmic Spark provides the 9480 "Sovereign Stack" for $10,000.

• The Hardware Edge: We leverage our "Enigma" supply chain to provide flagship Max Series silicon at a price point that undercuts standard 56-core Xeon Platinums.

• Thermal Validation: A 350W TDP chip with HBM2e requires precise cooling to prevent thermal throttling on the memory stacks. Our custom airflow systems are specifically tuned for the Xeon Max thermal profile.

• Deployment Advisory: We don't just sell you the chip; we advise you on which HBM Mode (Flat, Cache, or HBM-Only) will maximize your specific institutional throughput.

"The Xeon Max 9480 doesn't just process data; it lives inside the data. It is the ultimate expression of zero-latency sovereignty."
