Hot Chips 2026 mini series continues. 🔥
Part 6: Intel Diamond Rapids.
Intel presented Diamond Rapids, its next-generation Xeon CPU supporting up to 256 performance cores, at Hot Chips.
But 256 cores is only part of the story.
At that scale, memory bandwidth, latency, cache coherency and the fabric connecting those cores become increasingly important.
Our takeaway: scaling core count means scaling the architecture around those cores too.
We explore Intel’s approach, and how Flow PPU tackles another part of the scalability challenge by adding closely coupled parallel acceleration alongside the CPU.
