Microsoft‑backed D‑Matrix Begins Shipping Corsair AI Chip
D‑Matrix, a Microsoft‑backed startup founded in 2019, has begun shipping its Corsair AI inference chip in June 2026. The company says Corsair — an SRAM‑centric, tightly integrated memory-and-compute chip manufactured on TSMC's 6nm node — can run small-workload inference up to 10x faster and use up to 5x less energy than a standalone GPU when paired with an Nvidia Blackwell GPU, per cited Gimlet Labs research. D‑Matrix has raised about $500 million (≈ $2 billion valuation), will ship primarily to U.S. hyperscalers and frontier AI labs, and is partnering with Arista, Broadcom and Super Micro to deliver a rack-scale system called SquadRack. The startup plans a next-generation Raptor chip on TSMC 4nm next year.
A startup shipping an SRAM‑based inference chip with Microsoft backing and rack-scale partnerships could alter inference cost, energy efficiency and data‑center hardware choices, intensifying competition with Nvidia and impacting chip and DRAM demand.

AMD launches Helios rack AI system; Microsoft signs on
AMD announced Helios, its first rack-scale AI system, at the Advancing AI conference on July 23, 2026. Helios—designed to compete with Nvidia rack systems—integrates AMD Instinct GPUs, EPYC CPUs, Pensando-derived networking and system software, and is offered in four rack configurations optimized for large-scale training and inference. AMD said Helios will begin shipping later in 2026 and named early customers including Microsoft (which will deploy Helios in Azure), OpenAI, Meta, Oracle, Anthropic and Tata Consultancy Services. Anthropic and AMD announced a strategic partnership to deploy up to two gigawatts of GPUs using Helios. AMD framed Helios as a key enabler amid rising agentic-AI demand, introduced the Venice-X data-center CPU (expected 2027), and expects Helios to be a major data-center AI revenue driver beginning in 2027.
Microsoft Unveils Maia 200 Inference Accelerator
ChipStrat interviewed Saurabh Dighe, CVP of Azure Systems and Architecture at Microsoft, about Maia 200 — Microsoft’s second-generation AI accelerator designed specifically to optimize inference economics. Maia 200 targets performance-per-dollar and performance-per-watt for inference, with architectural trade-offs that favor inference workloads over training. Key technical choices discussed include a much larger on-die SRAM, a memory hierarchy balancing SRAM, HBM and system DRAM, and a preference for a large Ethernet-based scale-up domain with a custom transport layer. Microsoft positions Maia 200 as complementary to merchant GPUs within a heterogeneous fleet, exposing capacity through Azure services rather than as a standalone product. The interview also emphasizes KV cache management for long-context workloads and the importance of software investments (compilers, kernels, pre-silicon tooling) ahead of silicon.
MatX Raises $500M to Challenge Nvidia's AI Dominance
MatX, an AI chip startup founded in 2023 by former Google TPU engineers Reiner Pope and Mike Gunter, raised $500 million in a Series B round led by Jane Street and Situational Awareness (an investment fund formed by former OpenAI researcher Leopold Aschenbrenner). Other investors include Marvell Technology, NFDG, Spark Capital, and Stripe co‑founders Patrick and John Collison. MatX says its processors aim to be roughly 10x better than Nvidia GPUs for training and serving large language models. The company previously raised about $100 million in a 2024 Series A. MatX plans to manufacture its chips with TSMC and start shipping in 2027.
