Haunted by bottlenecks?😱 Even the fastest CPUs can’t escape the ghosts of serial execution. This #Halloween, we’re exorcising the limits of traditional architectures.
Our #PPU frees CPUs from their bottlenecks
so speed never has to be scary.⚡

New PPU performance results here! We’re comparing against the 5th Gen #Intel Xeon, boosting #CPU performance by 31x. The boost isn’t just a number. It’s proof that when parallelism becomes the starting point, CPU performance enters a new era. The results speak for themselves. #ParallelProcessing
Slide reading “Significant performance boost.” Text explains that Flow benchmarked its 256-core PPU proof-of-concept against state-of-the-art consumer and server CPUs across compute, memory-access, and synchronization patterns, showing major speed improvements. Graphic with the text “In this compute pattern test…” introducing the benchmark comparison context for the following performance chart. Bar chart showing benchmark comparison. Flow’s 256-core PPU is, on average, 31 times faster than a 48-core 5th Gen Intel Xeon CPU. Orange bar labeled 31× towers above a smaller black bar labeled 1, illustrating the performance gap. Closing graphic reiterating Flow’s message: “Speed is the superpower of computing. Flow’s PPU enables the next generation of CPU performance.” Positions the PPU as a key enabler of future high-speed architectures.

How does the #PPUt work? Pt 4
Scalability isn’t theoretical. It’s measurable. The PPU delivers 2x performance out of the box, & scales to extreme levels when optimized. This is what perfect linear scalability looks like in practice.

The PPU is instruction set independent.
It can be integrated w/ #arm, #x86 ( #amd, #intel), @riscv.org.web.brid.gy, & #OpenPower architectures. This flexibility means the #PPU can accelerate parallel workloads across different #CPU designs w/o being locked into a single ecosystem. #FlowComputing
