Apple says M5 Ultra uses a quad-die 3nm architecture, "a first for Apple silicon", with inter-die bandwidth of 4.4TB/s+ and up to a 36-core CPU and 80-core GPU
THE SO WHAT
Apple moving to a quad-die 3 nm M5 Ultra with 4.4 TB/s inter-die bandwidth and 80-core GPU is about keeping heavy local AI and 8K workflows off the cloud. For teams building pro apps, assume your users will expect serious on-device inference and media processing without external GPUs.

Applied AI'The version Microsoft will build should be known as Copilot OS': Windows built around AI may not be happening, but leaked concept remains a grim portent for desktops
An AI-centered OS concept means the assistant becomes the primary broker between users and apps—whoever owns that layer owns discovery and workflow routing. If Copilot-style shells materialize, app vendors will need to optimize for being called by agents, not clicked by humans.
Applied AIAI mental healthcare is here. Can it help people — or cause more problems?
Training a mental health AI on real therapy sessions raises both efficacy upside and consent, bias, and liability questions. Providers deploying these tools need hard guardrails—clear escalation paths to humans, transparent data provenance, and explicit patient opt-in—before they scale beyond pilots.
Applied AIOpenAI’s Jalapeno chip outperformed the GB300 on power and speed, according to OpenAI
If Jalapeno really delivers better work-per-watt and latency than GB300 for inference, the cost curve for serving large models just bent again. For operators, that means re-running your unit economics assumptions on where to host inference and how aggressively to lean into heavier models at the edge of your UX.
Applied AIWhy Meta’s stock could see a 50% rally, thanks to an overlooked AI wild card
If compute scarcity lets Meta sell excess capacity at a premium, infra becomes a profit center rather than just a cost of running models. For enterprises, that’s a reminder to lock in multi-year capacity where AI is mission-critical—or risk buying cycles at peak pricing from whoever has spare GPUs.
