Flow Computing emerges with licensable, on-die parallel processing

This is enabling 100X improved performance for any CPU architecture. It is capable of full backwards compatibility with existing software designed for servers, mobile devices or PCs.

Flow Computing Oy, the pioneer in licensing on-die ultra-high-performance parallel computing solutions to CPU vendors of all architectures, has emerged from stealth with an announcement of a total €4 million in pre-seed funding from several Nordic VC’s and business entities.


Capable of being integrated into any CPU design architecture, instruction set or process geometry, Flow provides a revolutionary 100-fold acceleration that is immediately usable in standard Von Neumann-based computer designs to enable “CPU 2.0”-levels of throughput. Flow also eliminates the need for expensive GPU acceleration of CPU instructions in performant applications. 


Flow’s groundbreaking new architecture, referred to as a Parallel Processing Unit (PPU), boosts the CPU performance up to 100-fold through PPU integrated on-die through a license from Flow. The PPU is fully backwards compatible with every existing software application for that CPU architecture - existing parallel functionality in all existing software and applications can be greatly accelerated by recompilation for the PPU without any software changes required.


The more PPU cores integrated on-die, the higher the performance boost that will be subsequently gained and Flow has optimized licenses for every major tier of CPU market application - mobile, PC and supercomputer. Flow’s technology is also complementary in nature to the entirety of the device motherboard as well as any peripheral boards - while it boosts the CPU, all other connected units (such as matrix units, vector units, NPUs and GPUs) holistically benefit from the performance of PPU and get a major boost from the now far-more-capable CPU.


Flow is already in initial discussions with major semiconductor vendors from around the world seeking the “Holy Grail” of next-generation CPU performance – more technical details will be publicly shared during the second half of 2024.


Participating entities in Flow’s pre-seed round include Butterfly Ventures (lead VC), FOV Ventures, Sarsia, Stephen Industries, Superhero Capital and Business Finland. As a spinout from the acclaimed VTT Technical Research Center of Finland, VTT maintains an equity stake in Flow Computing and all the patented IP developed over several years during this period has been officially transferred to Flow.

“We firmly believe there have been only incremental improvements in CPU performance during the last few decades - in our opinion, this has led to a situation where the CPU has actually become the weakest link in computing due to its sub-optimal sequential architecture,” said Timo Valtonen, co-founder and CEO of Flow Computing. 

"A new era in CPU performance has become a necessity in order to meet the continuously increasing demand for more computing performance, driven to large extent by needs in AI, as well as edge and cloud computing. Flow intends to lead the SuperCPU revolution through its radical new Parallel Performance Unit (PPU) architecture, enabling up to 100X the performance of any CPU, regardless of architecture and with full backwards software compatibility.”


Antti Vasara, CEO of VTT, said: “At VTT we are excited by the technical innovations of Flow Computing as Finland moves to become a world-leading exporter of cutting-edge semiconductor designs. They are providing a complete performance ecosystem to not only the CPU vendors, but the development communities that have coalesced around major CPU designs such as X86, Apple M-Series, Exynos, ARM and RISC-V. We are excited that Flow’s technology which has been developed at VTT is able to contribute in a significant way to the not just to Finnish and European computing ecosystem, but in the future of the whole computing industry!” 

Juho Risku, Partner and co-founder of Butterfly Ventures, added: “Every industry in tech continues to suffer due to the fact that the rate of CPU improvements has slowed over the last decade. Flow is the first major departure from this trend, offering multiples of performance instead of some percentage points and, in our opinion, Flow will have a broader impact on the baseline performance of the computing market than for example quantum computing in this decade. 

"Despite the huge investments in AI, general purpose computing will dominate its cost and constrain its capability. Flow Computing  is solving this problem by enabling the next generation of SuperCPUs to easily surpass current industry leaders such as the Apple M-series, Nvidia Grace, AMD Zen 5, Qualcomm Snapdragon Elite X, Intel Lunar Lake, Arm Cortex X, Google Axion and Microsoft Azure Cobalt 100."
