3-tile NPU on Intel 18A, delivering 45 TOPS at 10W, up to 75 TOPS at 35W
TDP options
10W (low-power) and 35W (high-performance) SKUs
Both versions support LPDDR5 and DDR5 memory, along with 12 PCIe 4.0 lanes .
Temperature and Radiation Tolerances
Operating temperature range: –55°C to +125°C (junction temperature)
Radiation hardening: Architecture includes protection against Total Ionizing Dose (TID), Single Event Latch-up (SEL), and Single Event Effects (SEE)
Status: Intel notes radiation characterization is still "in process" — the chip is not yet fully radiation-qualified
Lifecycle: Designed for a >10-year operational lifespan in orbit
What Intel Says It Is "Designed For"
Intel's official product page states Starfire is "designed for space grade survivability, advanced AI performance while meeting the size, weight and power constraints" of space missions . It is explicitly built for the U.S. government to satisfy stringent SWaP-C (size, weight, power, and cost) requirements .
Expansion of 18A Beyond Consumer and Data Center
Starfire marks Intel's first push of its leading-edge 18A node into the aerospace/defense segment, a market traditionally reliant on older, slower radiation-hardened chips. This demonstrates that 18A's RibbonFET gate-all-around transistors and PowerVia backside power delivery can be adapted for extreme-environment reliability, not just consumer/client or data center performance .
Separately, Intel announced that the 18A-P (performance-optimized) variant of the 18A node entered risk production in June 2026, announced at the VLSI Symposium in Honolulu. 18A-P offers a 9% performance uplift over baseline 18A at the same power . This expands 18A's application envelope into performance-optimized foundry workloads alongside Starfire's radiation-tolerant space-grade use case.
Comparison to Traditional Space-Grade Processors
Traditional space-grade processors operate at vastly lower performance levels:
Metric
Intel Starfire
BAE Systems RAD750 (typical space CPU)
Process node
Intel 18A (~1.8nm class)
0.25 μm (250nm) bulk CMOS
Clock speed
1.0 GHz (P-cores, 10W)
110–132 MHz
Performance
Multi-GHz, multi-core + GPU + NPU
~260 Dhrystone MIPS at 132 MHz
AI acceleration
45–75 TOPS NPU
None
Radiation tolerance
TID/SEL/SEE mitigation (in characterization)
200 Krad(Si) total dose, latchup-immune
Temp range
–55°C to +125°C
–55°C to +125°C
Starfire delivers orders-of-magnitude more compute performance and AI capability than any existing radiation-hardened processor, though its radiation qualification is ongoing whereas the RAD750 is fully qualified.
Implications for the Space Industry
Starfire brings modern consumer-class CPU architecture (Panther Lake derivatives), integrated GPU, and a dedicated NPU capable of 45–75 TOPS to space for the first time. This enables on-orbit AI inference (e.g., real-time image processing, autonomous navigation, anomaly detection) without relying on ground links. The small form factor, low power draw, and US-based manufacturing make it attractive for defense and scientific satellite programs where SWaP constraints are critical .
Launch Customers and Availability Timeline
No named customers have been disclosed. Intel's sell sheet does not identify specific launch customers or contracts .
Sampling: Intel Government Technologies is handling Starfire, with samples scheduled for Q3 2026.
Full specifications remain subject to change as radiation characterization and qualification continue .
