Introduction to ARM Architecture
The AWS Graviton processor family represents a groundbreaking advancement in cloud computing driven by the power and efficiency of the ARM architecture. As a Reduced Instruction Set Computing (RISC) architecture, ARM delivers exceptional performance and energy efficiency, making it a dominant force in diverse computing domains. AWS’s custom-designed Graviton processors leverage this inherent efficiency and combine it with AWS’s optimizations, resulting in remarkable performance, cost-effectiveness, and scalability for cloud workloads.
AWS offers three generations of Graviton processors, each building on the success of its predecessors. Graviton2, the second generation, introduced custom Neoverse cores, larger cache, and hardware accelerators, providing up to 7 times the performance of its predecessor. Now, the latest iteration, Graviton3, takes the evolution further with more optimizations, larger caches, and enhanced hardware accelerators, making it a compelling choice for a wide range of cloud applications.
Why do we need custom processors?
Custom processors are designed to cater to the unique needs of cloud-based services. Traditional processors, known as x86 processors, are great for running a wide range of applications, but they may not be the most efficient when it comes to handling certain workloads that are common in cloud computing.
AWS serves many customers who run various applications, from websites to databases and machine learning models. To deliver better performance and cost-effectiveness, AWS decided to design its processors tailored to their specific workloads.
How does AWS Graviton work?
Imagine you are baking a cake, and you have a dedicated tool for each step of the process. One tool might be great for mixing, another for frosting, etc. Similarly, AWS Graviton is designed with dedicated components that excel at different tasks, making the overall processing more efficient.
Imagine a busy road where different types of vehicles (cars, buses, bikes) are all mixed up, moving at different speeds. Now, visualize a dedicated highway lane for each type of vehicle: one for cars, one for buses, and one for bikes. This separation allows each vehicle to move at its optimal speed without being hindered by others.
- Similarly, AWS Gravitons architecture separates tasks into specialized components, allowing them to be executed faster and more efficiently.
- The architecture of Graviton processors leverages a technology called ARM (Advanced RISC Machines) architecture.
- This ARM architecture is different from the traditional x86 architecture you find in most computers. ARM processors are known for their energy efficiency and versatility, making them ideal for cloud workloads.
In a nutshell, Graviton processors have smaller and more streamlined components that allow them to execute specific tasks quickly and with less power. They’re like specialized tools that handle specific tasks in the cloud environment.
