T3 实例是下一代可突增通用实例类型，它提供基本水准的 CPU 性能，并且能够在需要的情况下随时突增 CPU 使用率。基于高频 Intel® Xeon® 可扩展处理器和 AWS Nitro 系统，T3 实例专为会在使用中遇到临时峰值的具有中等 CPU 使用率的应用程序而设计。
T3 实例为广泛的通用工作负载提供计算、存储和网络资源平衡，这些工作负载包括微服务、低延迟交互应用程序、中小型数据库、虚拟桌面、开发环境、代码库和业务关键型应用程序。
当工作负载的运行性能低于基准阈值时，T3 实例会累积 CPU 积分。获得的每个 CPU 积分都为 T3 实例提供了在需要时在一分钟内突增至一个完整 CPU 核心的性能的机会。只要在无限模式下需要，T3 实例就可以随时突增。
特点：
- 性能可突增的 CPU，受到 CPU 积分的限制，持续基本性能
- 默认为无限模式，可确保高峰期间的性能；标准模式选项可实现可预测的月度成本
- 与 T2 实例相比，AWS Nitro 系统和高频 Intel Xeon 可扩展处理器的性价比提升了 30%。
The 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. Additionally there is 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.

*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.
