Intel's 18A node is officially space-grade, according to documentation on Intel's website. A document that initially went unnoticed has been published, detailing a new "Starfire" generation of processors built on the 18A node and designed for space operations. Intel has designated two SKUs for orbital computing, each equipped with four P-Cores and four LPE-Cores, resulting in an eight-core SoC design. One is optimized for low-power operations with clocks adjusted for efficiency, while the other is designed for performance. The Low Power edition tunes its four P-Cores to 1.0 GHz, while the four LPE-Cores run at 850 MHz. For the Performance version, Intel has increased the frequency of P-Cores to 3.1 GHz, with LPE-Cores reaching up to 2.1 GHz.

Both SKUs feature a GPU tile built on the Intel 3 node, which includes 4 Xe cores with 64 EUs. On the Low Power SKU, these Xe cores operate between 800 MHz and 1.0 GHz, while the Performance SKU boosts this to 2.0 GHz. The total package for the Low Power version remains at 10 W TDP, while the Performance SKU is capped at 35 W TDP. Additionally, Intel includes an NPU on both versions, with a compute capability of 45 TOPS on the Low Power version and up to 75 TOPS on the Performance SKU using INT8 precision. Beyond specifications, "Starfire" can operate within a T-Junction range from -55°C to 125°C. This range, alongside TID, SEL, and SEE radiation hardening certifications, introduces the first 18A silicon to space, ideal for orbital computation. Intel targets this quarter, Q3, for samples.
