Amazon EC2 T3 Instances
T3 instances are the next generation low cost burstable general-purpose instance type that provide a baseline level of CPU performance with the ability to burst CPU usage at any time for as long as required. T3 instances are designed for applications with moderate CPU usage that experience temporary spikes in use.
T3 instances offer a balance of compute, memory, and network resources for a broad spectrum of general purpose workloads including micro-services, low-latency interactive applications, small and medium databases, virtual desktops, development environments, code repositories, and business-critical applications.
EC2 T3a Instances - Now Available
T3a instances feature AMD EPYC processors with an all core turbo clock speed of up to 2.5 GHz and offer a 10% cost savings over T3 instances.
Low Cost Burstable CPU Performance
T3 instances are a low cost Amazon EC2 instance type designed to provide a baseline level of CPU performance with the ability to burst above the baseline using CPU credits. T3 instances accumulate CPU credits when a workload is operating below baseline threshold. Each earned CPU credit provides the T3 instance the opportunity to burst with the performance of a full CPU core for one minute when needed. T3 instances are unlike any other burstable instance available in the market segment today in that customers can sustain high CPU performance for any period of time, whenever and however long required, and avoid application degradation if the instance exceeds its available CPU credits.
Unlimited and Standard Mode
T3 instances start in Unlimited mode by default, giving users the ability to sustain high CPU performance over any desired time frame while keeping cost as low as possible. For most general-purpose workloads, T3 Unlimited instances provide ample performance without any additional charges. If the average CPU utilization of a T3 instance is lower than the baseline over a 24-hour period, the hourly instance price automatically covers all interim spikes in usage. If the instance needs to run at higher CPU utilization for a prolonged period, it can do so for an additional charge of $0.05 per vCPU-hour. In Standard mode, a T3 instance can burst until it uses up all of its earned credits.
Multiple Processor Choices
T3 instances feature the Intel Xeon Platinum 8000 series (Skylake-SP) processor with a sustained all core Turbo CPU clock speed of up to 3.1 GHz, and deliver up to 30% improvement in price performance compared to T2 instances. T3 instances provide support for the new Intel Advanced Vector Extensions 512 (AVX-512) instruction set, offering up to 2x the FLOPS per core compared to the previous generation T2 instances. T3a instances feature the AMD EPYC 7000 series processor with an all core turbo clock speed of up to 2.5 GHz. T3a offers up to 10% savings for customers who are looking to further cost optimize their Amazon EC2 compute environments.
Built on the AWS Nitro System
T3 instances are built on the AWS Nitro System, a rich collection of building blocks that offloads many of the traditional virtualization functions to dedicated hardware. By doing so, the AWS Nitro System enables high performance, high availability, and high security while also reducing virtualization overhead.

*Prices shown are for Linux/Unix in US East (Northern Virginia) AWS Region. Prices for 1-year and 3-year reserved instances are for "Partial Upfront" payment options or "No upfront" for instances without the Partial Upfront option. For full pricing details, see the Amazon EC2 pricing page.
T3 instances accumulate CPU credits when operating below baseline threshold. One CPU credit is equal to one vCPU running at 100% utilization for one minute. See T3 Unlimited documentation for details on CPU Credits and how they work.
