Cerebras turns inference into revenue
Cerebras Systems reported record GAAP revenue of $210.8 million for the third quarter of 2026, and reported record Core revenue of $230.9 million for the same quarter. The company raised its full-year 2026 Core revenue outlook to $940 to $960 million, and expects to triple revenue in 2027. Those are filing numbers, not marketing claims, and they describe a challenger moving from promise to purchase orders. m:…2586
Cerebras Systems has 700 megawatts of data center capacity under contract as of September 30, 2026, and reported $26.1 billion in remaining performance obligations as of the same date. The company expects to exit 2026 with more than 10x manufacturing capacity compared to the beginning of the year. Remaining performance obligations are work already sold but not yet delivered, so the $26.1 billion figure is a backlog, not a forecast, and it is the number that makes the tripling claim for 2027 worth taking seriously. m:…2586
Oracle is integrating Cerebras' inference technology into Oracle Cloud Infrastructure, with availability expected in 2027, and Cerebras announced a new cloud deal with a top-three hyperscaler. The company previewed the CS-5 system, targeted for early Summer 2027 and designed to deliver up to 10,000 tokens per second per user. The hyperscaler deal is unnamed, which limits how much weight it can carry, but the Oracle integration is named and dated, and it puts Cerebras inside a major cloud's inference stack. m:…2586
AMD aims at science, not just AI
The AMD Instinct MI430X features 432 GB of HBM4 memory, provides 50% more memory capacity than Nvidia Vera Rubin, and is the first GPU designed for the convergence of high-precision compute and AI for science, according to AMD. The comparison with Vera Rubin is AMD's own framing, but the memory figure is the point: large models and scientific simulations both need memory, and the MI430X is built for workloads that need both. m:…1980
The AMD Instinct MI430X has been selected for the Discovery supercomputer at Oak Ridge National Laboratory, the Alice Recoque system in France, and the Herder system at HLRS in Germany. Three supercomputer selections in three countries are a stronger signal than a spec sheet, because national labs buy on measured performance and long support horizons. AMD Instinct MI430X projected HPL performance is 190 TFLOPs, and the chip is built on the AMD CDNA 5 architecture. m:…1980
AMD powers scientific computing systems including Frontier, El Capitan, LUMI and Lux. The MI430X extends a position AMD already holds in high-performance computing into the AI era, rather than starting from zero against an entrenched incumbent. m:…1980
A smaller challenger bets on air cooling
Axelera AI unveiled Titania, its third-generation silicon architecture in a chiplet design. The company says Titania offers up to 7x the throughput per watt compared with existing data center-grade servers and up to 20x better TCO compared with existing data center-grade servers. Titania delivers performance within the power and cooling limits of existing data centers, which is the real pitch: no liquid-cooled racks, no new building, just faster chips in the rooms customers already have. m:…9781
Axelera AI has secured over $300 million in confirmed Titania commitments, and the AX8 reference server provides 20 PFLOPS of FP8 compute within a 4U air-cooled server. Titania production is scheduled for Q3 2027. The $300 million in commitments is the number to watch, because it is the difference between a chip announcement and a chip business. Titania uses LPDDR6 memory to provide 128 GB of capacity per package, and the architecture is designed to avoid dependence on HBM supply, which has been a bottleneck for the whole industry. m:…9781
Power is the other bottleneck
Exowatt has launched P3 Gen 2, the next generation of its modular solar-thermal energy system, and introduced Exobloc, a standardized 1 MW clean, firm power block. P3 Gen 2 development is based on more than 7,000 hours of testing, and the new generation offers a higher capacity factor than the previous generation. The product is power, not chips, and it addresses the constraint that now decides where AI data centres can be built. m:…8233
The Athena site in West Texas is a 2.4 GW project designed to run on 80% renewable energy, and the site will connect to ERCOT in two phases with 1,200 MW of capacity. Exowatt is developing an AI-powered, agentic energy management system for P3. The agentic energy system is the company's own description of its software, and it is early, but the power numbers are concrete: a 2.4 GW site is the scale at which AI infrastructure and the electricity grid meet, and whoever can deliver firm power at that scale decides where the next data centres go. m:…8233
What is still unresolved
- Whether Cerebras can deliver on $26.1 billion in remaining performance obligations
- Whether Titania's $300 million in commitments converts to shipped systems in Q3 2027
- Whether firm clean power can scale fast enough for AI data centre demand
