<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
AMD announced a definitive agreement to acquire Toronto-based chip startup Taalas to expand its specialized AI inference portfolio. Taalas develops custom silicon architectures that hard-wire individual AI model weights directly into semiconductor metal layers during manufacturing. AMD plans to integrate Taalas' low-cost, ultra-efficient inference technology directly into its broader accelerator roadmap alongside Instinct GPUs.

<strong>Blue Origin Traces May's New Glenn Explosion to a Faulty BE-4 Engine Valve (3 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Blue Origin CEO Dave Limp said the May explosion that destroyed a New Glenn rocket during a prelaunch engine test originated at the main oxygen valve on one of its BE-4 engines, confirmed through hardware recovery and inspection. The fix is straightforward: small modifications to the valve that can be quickly retrofitted onto existing engines, with the company aiming to return New Glenn to flight later this year. The BE-4 also powers United Launch Alliance's Vulcan rocket, so ULA has been collaborating with Blue Origin on the investigation. The finding gives both companies a clear, containable root cause rather than an open-ended engine redesign.

<strong>D-Wave's Dual-Rail Qubit Gate Hits 99.9% Fidelity, Cutting Error-Correction Overhead (4 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
D-Wave published research in Nature demonstrating a new two-qubit entangling gate for its superconducting "dual-rail" qubit architecture, which is designed so the most common quantum errors are also the easiest kind to detect and fix. The gate hit roughly 99.9% fidelity with fast ~500 nanosecond operation times, while preserving native hardware-level error detection, meaning errors get caught directly by the qubit design rather than requiring extra correction circuitry bolted on afterward.

<strong>How To Scale AI Arithmetic Efficiently (4 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
This technical analysis explores how arithmetic specialization is essential for scaling artificial intelligence compute performance. As traditional transistor scaling slows down, hardware designers are replacing general-purpose IEEE floating-point units with specialized arithmetic engines tailored to low-precision representations like FP8, FP4, and Microscaling (MX) formats. By optimizing number format combinations and operation depth directly within silicon arithmetic units, modern AI accelerators drastically reduce energy consumption per operation while maximizing throughput without swelling total die area or power budgets.

<strong>Nvidia and Google Are Crowding TSMC's N3 Node, Creating a Rare Opening for Intel (5 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Nvidia's next-gen Rubin GPUs are moving from 4nm to TSMC's 3nm node just as Google's TPUs, which are already on N3, plan to stay there, while new AI CPUs from Nvidia, Amazon, Microsoft, and Arm are converging on the same process simultaneously. TSMC has already hit its planned N3 capacity and is still adding more, warning the node could stay "very tight" for years, with three of its four Arizona fabs reportedly already fully booked despite only one being operational, driving reported price hikes of up to 25% for some customers. That squeeze creates a real opening for Intel, whose Fab 52 in Arizona just entered full production at 40,000 18A wafer starts per month, more capacity than TSMC's original Fab 21 campus.

<strong>Breaking the Memory Wall With CXL (4 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
The Diligence Stack analyzes how Compute Express Link (CXL) technology breaks the persistent memory wall in high-density AI infrastructure. By utilizing PCIe physical interfaces to provide memory-semantic access, CXL enables memory expansion and multi-node pooling directly across server clusters. This architecture offloads Key-Value caches and massive vector databases from constrained GPU memory without severe latency penalties. Consequently, data centers can eliminate stranded DRAM resources, drastically reducing hardware costs, and scale memory capacity independently from fixed CPU channel limits.
