RISC V vs ARM: The Future of Open-Source CPU Architecture
RISC-V and ARM are two of the most important CPU architectures currently on the market. They power everything from Internet of Things devices to high-performance supercomputers. Although ARM is the industry standard for mobile and embedded devices due to its well-established ecosystem and successful track record, RISC-V is rapidly gaining traction as an open-source, highly configurable alternative. This competition is altering computer architecture and affecting industry heavyweights like IBM, AMD, and Intel.
Both designs are necessary for modern computing. ARM is extensively utilised in embedded systems, GPUs, and mobile devices due to its robust ecosystem and power efficiency. Meanwhile, RISC-V’s open-source model, which promotes innovation and customisation, makes it a popular choice for startups, academic research, and specialised applications like FPGA designs and custom microprocessors.
RISC V vs ARM – Overview
The table below shows the complete overview of the RISC V vs ARM.
| Attributes | RISC V | ARM |
|---|---|---|
| Open Source | Full Open-Source ISA | Proprietary of ARM Holding |
| Customization | Highly Customizable | Limited Customization |
| Power Consumption | Less than 1 Watt | Less than 4 Watt |
| Floating Point and General-Purpose Registers | 32 | 31 |
| Domain | Embedded Systems, AI (Artificial Intelligence) and Automotive | Embedded Systems, Smartphone and Tablets |
| Instruction Set | Fixed Length 32-bit | Fixed Length 32-bit & 64-bit |
| Performance | Optimized for specific applications | High Performance |
An Instruction Set Architecture, or ISA, is what?
At the core of RISC V vs ARM is each processor’s Instruction Set Architecture (ISA), or the architecture that outlines how it will execute commands. A CPU’s ISA determines its capabilities, performance, compatibility, and power efficiency. They act as the crucial connection between hardware and software, influencing everything from coding languages to system architecture.
There are two main types of ISAs: closed ISAs, like ARM, and open ISAs, like RISC-V.
- Certain companies own and run closed ISAs. For example, when licensing their ISA to manufacturers, ARM Holdings tightly controls its features and use. This approach ensures compatibility and reliability even though it limits customisation.
- Programmers can expand and alter the architecture to meet particular requirements using RISC-V and other community-driven open ISAs. This promotes innovation and releases companies from license fees and vendor lock-in, allowing them to optimise processors for specialised applications.
This fundamental difference in approach has sparked a debate about the future of processor design, with RISC-V challenging ARM’s dominance by encouraging openness and flexibility.
Comprehensive Comparisons: ARM vs RISC-V
Comparing RISC-V and ARM will allow for a more in-depth examination of each processor because both are crucial. One is open-source, and the other is the well-known proprietary alternative. The ARM architecture is largely controlling the embedded systems and mobile industries due to its superior performance and energy efficiency. Because of its versatility, scalability with other cooperative solutions, and free, open-source license, the RISC-V processor is growing in popularity and becoming a formidable competitor.
This comprehensive comparison of RISC V and ARM helps organisations make informed decisions about which processors will best help them achieve their goals.
Vendor Independence
In RISC V vs ARM, Because the RISC-V CPU belongs to an open-source model, it liberates enterprises from vendor lock-ins on hardware and software, providing freedom of choice for procurement of solutions that best suit their needs. Other than this advantage of freedom from vendor lock-ins, it enables them to customize the solution and ensures stability and sustainability in the long run. On top of that, companies recommend individuals participate actively in the RISC V community to share ideas and information so as to gain fully from this ecosystem; however, inadequate participation will also impede the development of this ecosystem toward gaining fully from the fruits of the RISC-V processor.
Cost-Effectiveness
In RISC V vs ARM, By eliminating license fees the RISC-V CPU guarantees no vendor dependency as it is open source, extra expenses are cut. Other financial benefits include the lower cost that comes with designing its instruction set making development, manufacturing, and verification easier hence cheap production.
Dominance of the Market
More than 10 billion RISC-V CPUs have been deployed across various uses, but ARM holds over 95% of the smartphone market. Due to its many years and large role in the computing field, ARM has built a complex network with many types of processing cores and top-notch software help, making it a favorite choice for many firms around the globe. Even though the open-source aspect of RISC-V CPU has started to grow its fame, it will be quite some time before it can surpass ARM.
Hardware Security Infrastructure
Any device must have a flawless security infrastructure, but this is especially important for vital industries like the military and finance. The application of ARM’s strong security architecture necessitates confidence in its designs, which ARM Holding and its partners supply. However, because the RISC-V processor is open source, it offers an entirely different approach. The freedom to directly handle security measures allows developers and organisations to fully monitor the architecture, keep an eye out for any vulnerabilities, and modify security features to suit their needs. For high-security applications where the company need total control and a thorough grasp of the hardware foundation, this kind of security customisation is advantageous.

Disparities in the Design of Architecture
- ISA Availability: Proprietary standard (ARM) against open standard (RISC-V).
- Customisation: Fixed feature set based on ARM’s intellectual property versus unlimited extensibility with custom instructions (RISC-V).
- Cost Model: Royalty and licence payments (ARM) against no licensing fees (RISC-V).
- Governance: Development driven by the community and foundations as opposed to development and control by a single firm.
In RISC V vs ARM, While ARM is a proprietary ISA that has emerged as the preferred option for embedded systems and mobile devices, RISC-V is an open-source ISA built on the ideas of reduced instruction set computing (RISC).
Conclusion on the RISC V vs ARM
In this article of the RISC V vs ARM, we have discussed in detail about the RISC V vs ARM. RISC-V processors are found at the heart of low-power embedded systems, Internet of Things devices, data centers, desktop PCs, and high-performance computing applications. At the same time, ARM CPUs enable mobile devices while also supporting embedded systems and Internet of Things devices as well as data centers in addition to real-time and safety-critical systems.
