Slide titled “What’s driving CPU demand” with a datacenter image showing a person monitoring equipment. Key points: reinforcement learning requires large CPU clusters; agents, RAG, and tool use increase general-purpose compute; CPUs handle data preparation, indexing, decoding, and orchestration; large CPU fleets keep GPU clusters fully utilized. Source: SemiAnalysis, 2026.
Slide titled “Scaling CPUs isn’t simpler” with abstract chip-like background. Key points: core counts are rising but interconnect and memory behavior matter more; latency, coherence, and NUMA effects become major constraints; feeding accelerators reliably becomes the system bottleneck.
Slide titled “A better way to scale CPU performance” with illustration of a CPU and Flow PPU chip. Text explains that Flow PPU enables scalable parallel execution inside the CPU by offloading parallel workloads without increasing core count, enabling linear scaling for data-intensive tasks, improving throughput to reduce system bottlenecks, and supporting x86, Arm, RISC-V, and OpenPOWER architectures.

Flow Computing team members sitting together on a sofa in a modern office lounge, smiling toward the camera in a collaborative workspace environment.
Part of the team met in #Helsinki for focused collaboration. We're glad Hugo Pompougnac & Jordi Sala Juárez joined the sessions stepping Senior Compiler Engineers roles. Building next-gen #CPU performance requires close alignment. Strengthening our compiler team is important as we develop #FlowPPU.
This is what makes #FlowPPU relevant across a wide range of compute environments.

Michael Bancroft from Beyond Innovation interviewing about Flow Computing’s licensable processor technology and CPU performance innovation.
Timo Valtonen, CEO and co-founder of Flow Computing, discussing Flow PPU and the role of speed and parallel processing in next-generation CPUs.
NextGen performance comes from how efficiently parallel work happens inside CPUs. #FlowPPU is built around this: #ParallelProcessing integrates directly into the #CPU; Works across architectures - x86, arm, @riscv.org.web.brid.gy, OpenPower; Configurable for different targets (hyperscale - edge).
