RISC-V (pronounced “risk-five”) is an open-source instruction set architecture (ISA) based on reduced instruction set computing (RISC) principles. It was developed at the University of California, Berkeley, and is now maintained by the RISC-V Foundation.
The RISC-V ISA is designed to be a modular, extensible instruction set that can be used for a wide range of applications, including embedded systems, computer architectures, and high-performance computing. It is gaining popularity among researchers and industry professionals due to its open-source nature and the ability to customize the ISA for specific applications.
One of the main advantages of RISC-V is that it is open-source, meaning that anyone can use, modify, and distribute the ISA without having to pay licensing fees or royalties. This allows companies and individuals to develop custom processors and systems-on-chips (SoCs) that are tailored to their specific needs and requirements.

Fastest RISC-V CPU
Note: These CPUs are not for your desktop yet but rather some are for data center, some are for high-performance embedded applications. However, many of these CPUs are capable of running a desktop operating system like Linux, so they may be suitable for certain types of desktop or edge computing applications. It is important to carefully consider the specific capabilities and limitations of each CPU before deciding which one is right for your needs.
In this article, we will take a look at some of the most powerful RISC-V processors available today.
It’s difficult to trust their claims regarding CPU performance, but it’ll be interesting to see what risc v does for the computer industry. Geopolitics are becoming increasingly uncertain, so risc v may have already secured its future.
Esperanto ET-SoC-1
This is a commercially available risc v chip, that clams to be one of the fastest risc v in the world, its companey clams that ET-MaxionTM core is designed to deliver high-performance out-of-order single-thread RISC-V execution. ET-MinionTM core compute array is designed for energy efficiency while delivering hundreds of TeraOps of computing performance.
| Cores | 4 high-performance ET-Maxion 64-bit RISC-V out-of-order cores |
| Ram Compatibility | Interfaces for large external memory with low-power LPDDR4x DRAM and eMMC FLASH |
P550 CPU
SiFive’s new Performance P550 core is a powerful RISC-V processor with a 13-stage, triple-issue, out-of-order pipeline. The P550 is Linux-capable and boasts full V extension support, making it suitable for heavily vector-math-dependent applications.
SiFive claims that a four-core P550-based CPU takes up the same on-die area as a single Arm Cortex-A75 but offers significantly better performance. In fact, SiFive says the P550 delivers 8.65 SPECint 2006 per GHz, according to internal engineering test results. This puts it ahead of the Cortex-A75 and not too far behind an i9-10900K, but behind an Apple A14. Overall, the P550 is a strong contender in the list of the most powerful RISC-V processors.
