Bolt Graphics Successfully Powers On First Test Silicon for Zeus GPU

Semiconductor startup Bolt Graphics has reached a major hardware milestone by successfully powering on the first silicon for its upcoming Zeus GPU project. Manufactured by TSMC on a 12nm process node, the test chip measures 6 square millimeters and draws 1.4 watts of power. According to the company, the initial test run executed without any issues, marking a shift away from the FPGA prototyping boards the engineering team previously relied on.

The core architecture of the Zeus project relies on open-standard RISC-V processor cores coupled with proprietary path-tracing hardware. Unlike conventional consumer graphics cards, the intended PCIe cards will combine soldered LPDDR5X memory with standard laptop-style DDR5 SO-DIMM slots, allowing end users to scale capacity up to 384GB. Furthermore, the hardware features dedicated circuitry designed specifically to accelerate complex electromagnetic simulations used in developing radar sensors and camera lenses.

While the initial test chip has cleared internal performance estimates, the final Zeus GPU destined for production will utilize TSMC's N5P process node. Bolt deliberately selected this older node to sidestep supply chain congestion and avoid competing for bleeding-edge wafer allocations. The company has also expanded its physical footprint by opening an office in Taipei to maintain close proximity to its manufacturing partners.

Commercialization efforts are currently focused on engineering, scientific, and studio workloads before any broader expansion into gaming or artificial intelligence markets. Reports indicate the startup is simultaneously pursuing a $100 million funding round at a $700 million valuation. Despite ambitious performance claims regarding rendering speeds and electromagnetic simulation throughput, independent benchmarks remain unavailable as volume production is not expected until 2028.
