Description

The Blackhole™ is a high-performance AI processing unit that takes advantage of scalable PCIe boards designed for demanding AI tasks. It boasts an impressive architecture featuring 16 big RISC-V cores, complemented by up to 32GB of GDDR6 memory per chip, offering exceptional power for AI processing. In its various configurations, such as the p100a and p150a models, the Blackhole provides a choice in capabilities, whether it be in core count or connectivity.

The p100a model of the Blackhole™ is defined by its 120 Tensix Cores, supplied with 28 GB of GDDR6, ensuring that even intensive computational tasks benefit from seamless operation and speed. With a GPU-like infrastructure, the design focuses on a power-efficient yet formidable processing environment, pushing up to 300W, tailored for desktops.

Meanwhile, the p150a variant enhances these specifications with 140 Tensix Cores and 32GB of GDDR6, along with extensive connectivity options like four passive QSFP-DD 800G ports. This feature allows multiple cards to link together, optimizing memory pooling and performance across arrays, making it ideal for high-performance computing and AI-driven workloads.
