# CPU options for Amazon EC2 instances
<a name="instance-optimize-cpu"></a>

Many Amazon EC2 instances support simultaneous multithreading (SMT), which enables multiple threads to run concurrently on a single CPU core. Each thread is represented as a virtual CPU (vCPU) on the instance. An instance has a default number of CPU cores, which varies according to instance type. For example, an `m5.xlarge` instance type has two CPU cores and two threads per core by default—four vCPUs in total.

In most cases, there is an Amazon EC2 instance type that has a combination of memory and number of vCPUs to suit your workloads. However, to optimize your instance for specific workloads or business needs, you can specify the following CPU options during and after instance launch:
+ **Number of CPU cores**: You can customize the number of CPU cores for the instance. You might do this to potentially optimize the licensing costs of your software with an instance that has sufficient amounts of RAM for memory-intensive workloads but fewer CPU cores.
+ **Threads per core**: You can disable SMT by specifying a single thread per CPU core. You might do this for certain workloads, such as high performance computing (HPC) workloads.

**Considerations**
+ You can't modify the number of threads per core for T2, C7a, M7a, R7a, and Apple silicon Mac instances, and instances based on the AWS Graviton processor.
+ The [number of instances that you can run](https://docs.aws.amazon.com/ec2/latest/instancetypes/ec2-instance-quotas.html) is based on the default vCPUs for the instance types used. How we calculate the vCPUs consumed by an instance is not affected by changing its CPU options.

**Pricing**  
There is no additional charge for specifying CPU options. For EC2 instances that are launched from license-included Windows and SQL Server AMIs, you can customize the CPU options to take advantage of the EC2 Optimize CPUs feature to pay licensing fees based on the number of vCPUs that are configured for your instance. For other EC2 instances, you're charged the same as instances that are launched with the default CPU options.

# Rules for specifying CPU options for an Amazon EC2 instance
<a name="instance-cpu-options-rules"></a>

To specify the CPU options for your instance, be aware of the following rules:
+ You can't specify CPU options for bare metal instances.
+ You can specify CPU options both during and after instance launch.
+ To configure CPU options, you must specify both the number of CPU cores and threads per core in the request. For example requests, see [Specify CPU options for an Amazon EC2 instance](instance-specify-cpu-options.md).
+ The number of vCPUs for the instance is the number of CPU cores multiplied by the threads per core. To specify a custom number of vCPUs, you must specify a valid number of CPU cores and threads per core for the instance type. You cannot exceed the default number of vCPUs for the instance. For more information, see [Supported CPU options for Amazon EC2 instance types](cpu-options-supported-instances-values.md).
+ To disable simultaneous multithreading (SMT), also referred to as hyper-threading, specify one thread per core.
+ In the console, when you [change the instance type](ec2-instance-resize.md) of an existing instance, Amazon EC2 applies the CPU option settings from the existing instance to the new instance, if possible. If the new instance type doesn't support those settings, the CPU options are reset to **Use default CPU options**. This option uses the default number of vCPUs for the new instance type.

  To update settings for the new instance, select **Specify CPU options** under **Advanced details** in the **Change instance type** view.
+ The specified CPU options persist after you stop, start, or reboot an instance.
+ If you use Reserved Instances, discounts may not be applied when you configure Optimize CPUs for instances launched from license-included Windows AMIs in the same payer account. We recommend that you use Savings Plans to reduce vCPU-based licensing costs and provide comparable savings on your compute costs.
+ To save on licensing costs for instances launched from Windows and SQL Server license-included AMIs, you must configure a minimum of four vCPUs. If you configure fewer than four vCPUs, default billing is applied.
+ Optimize CPUs for License-Included instances is not supported on T3 instance types.

## Change CPU options for your EC2 instance
<a name="change-vCPUs-after-launch"></a>

As your needs change over time, you might want to change the configuration of CPU options for an existing instance. Each thread that runs on your instance is known as a virtual CPU (vCPU). You can change the number of vCPUs that run for an existing instance in the Amazon EC2 console, AWS CLI, API, or SDKs. The instance state must be `Stopped` before you can make this change.

To view console or command line steps, select the tab that matches your environment. For API request and response information, see [ModifyInstanceCpuOptions](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_ModifyInstanceCpuOptions.html) in the *Amazon EC2 API Reference*.

------
#### [ Console ]

Follow this procedure to change the number of active vCPUs for your instance from the AWS Management Console.

1. Open the Amazon EC2 console at [https://console.aws.amazon.com/ec2/](https://console.aws.amazon.com/ec2/).

1. In the left navigation pane, choose **Instances**. This opens the list of instances that are defined for the current AWS Region.

1. Select the instance from the **Instances** list. Alternatively, you can select the instance link to open the instance detail page.

1. If the instance is running, you must stop it before you proceed. Choose **Stop instance** from the **Instance state** menu.

1. To change the vCPU configuration, choose **Change CPU options** from **Instance settings** in the **Actions** menu. This opens the **Change CPU options** page.

1. Choose one of the following CPU options to change the configuration for your instance.  
**Use default CPU options**  
This option resets your instance to the default number of vCPUs for the instance type. The default is to run all threads for all CPU cores.  
**Specify CPU options**  
This option enables configuration of the number of vCPUs that are running on your instance.

1. If you chose **Specify CPU options**, the **Active vCPUs** fields are displayed.
   + Use the first selector to configure the number of threads for each CPU core. To disable simultaneous multithreading, choose `1`.
   + Use the second selector to configure the number of CPUs that run on your instance.

   The following fields dynamically update as you make changes to the CPU option selectors.
   + **Active vCPUs**: The number of CPU cores multiplied by the threads per core, based on the selections that you made. For example, if you selected 2 threads and 4 cores, that would equal 8 vCPUs.
   + **Total vCPUs**: The maximum number of vCPUs for the instance type. For example, for an `m6i.4xlarge` instance type, this is 16 vCPUs (8 cores running 2 threads each).

1. To apply your updates, choose **Change**.

------
#### [ AWS CLI ]

Follow this procedure to change the number of active vCPUs for your instance from the AWS CLI.

Use the [modify-instance-cpu-options](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/ec2/modify-instance-cpu-options.html) command and specify the number of CPU cores that run in the `--core-count` parameter, and the number of threads that run per core in the `--threads-per-core` parameter.

The following examples show two possible configurations on an `m6i.4xlarge` instance type to run 8 vCPUs on the specified instance. The default for this instance type is 16 vCPUs (8 cores running 2 threads each).

**Example 1:** Run 4 CPU cores with 2 threads per core, for a total of 8 vCPU.

```
aws ec2 modify-instance-cpu-options \
    --instance-id i-1234567890abcdef0 \

    --core-count=4 \
    --threads-per-core=2
```

**Example 2:** Disable simultaneous multi-threading by changing the number of threads that run per core to `1`. The resulting configuration also runs a total of 8 vCPUs (8 CPU cores with 1 thread per core).

```
aws ec2 modify-instance-cpu-options \
    --instance-id 1234567890abcdef0 \
    --core-count=8 \
    --threads-per-core=1
```

------
#### [ PowerShell ]

**To change the number of active vCPUs for an instance**  
Use the [Edit-EC2InstanceCpuOption](https://docs.aws.amazon.com/powershell/latest/reference/items/Edit-EC2InstanceCpuOption.html) cmdlet and specify the number of CPU cores that run in the `-CoreCount` parameter, and the number of threads that run per core in the `ThreadsPerCore` parameter.

**Example 1:** Run 4 CPU cores with 2 threads per core, for a total of 8 vCPU.

```
Edit-EC2InstanceCpuOption `
    -InstanceId 'i-1234567890abcdef0' `
    -CoreCount 4 `
    -ThreadsPerCore 2
```

**Example 2:** Disable simultaneous multi-threading by changing the number of threads that run per core to `1`. The resulting configuration also runs a total of 8 vCPUs (8 CPU cores with 1 thread per core).

```
Edit-EC2InstanceCpuOption `
    -InstanceId 'i-1234567890abcdef0' `
    -CoreCount 8 `
    -ThreadsPerCore 1
```

------

# View CPU threads and cores for an Amazon EC2 instance
<a name="view-cpu-options"></a>

You can view the CPU options for an existing instance by describing the instance.

------
#### [ Console ]

**To view the CPU options for an instance**

1. Open the Amazon EC2 console at [https://console.aws.amazon.com/ec2/](https://console.aws.amazon.com/ec2/).

1. In the left navigation pane, choose **Instances** and select the instance.

1. On the **Details** tab, under **Host and placement group**, find **Number of vCPUs**.

------
#### [ AWS CLI ]

**To view the CPU options for an instance**  
Use the [describe-instances](https://docs.aws.amazon.com/cli/latest/reference/ec2/describe-instances.html) command.

```
aws ec2 describe-instances \
    --instance-ids i-1234567890abcdef0 \
    --query Reservations[].Instances[].CpuOptions
```

The following is example output. The `CoreCount` field indicates the number of cores for the instance. The `ThreadsPerCore` field indicates the number of threads per core.

```
[
    {
        "CoreCount": 24, 
        "ThreadsPerCore": 2
    }, 
]
```

------
#### [ PowerShell ]

**To view the CPU options for an instance**

```

The following is example output.

```
AmdSevSnp CoreCount ThreadsPerCore
--------- --------- --------------
          24        2
```

------

Alternatively, to view CPU information, you can connect to your instance and use one of the following system tools:
+ Windows `Task Manager` on your Windows instance
+ The **lscpu** command on your Linux instance

You can use AWS Config to record, assess, audit, and evaluate configuration changes for instances, including terminated instances. For more information, see [Getting Started with AWS Config](https://docs.aws.amazon.com/config/latest/developerguide/getting-started.html) in the *AWS Config Developer Guide*.

# Optimize CPUs for License-Included instances
<a name="optimize-cpu"></a>

Workloads such as Microsoft SQL Server often require high levels of memory and IOPS but a low vCPU count. AWS provides a broad set of instance types that can cover most of your infrastructure needs. However, to reduce vCPU-based licensing costs for Windows and Microsoft SQL Server, you can customize the number of vCPUs running on your EC2 instance while maintaining the same memory, storage, and network specifications. This approach can save on vCPU-based licensing costs for both license-included and Bring-Your-Own-License (BYOL) workloads. You can specify CPU options when you launch or modify an instance by using the console or the Amazon EC2 API. For instructions, see [Specify CPU options for an Amazon EC2 instance](instance-specify-cpu-options.md).

For more information, see this [blog post](https://aws.amazon.com/blogs/modernizing-with-aws/optimize-cpus-best-practices-for-sql-server-workloads-continued/) about best practices to optimize CPUs for SQL Server workloads.

## Supported license types
<a name="win-opt-cpu-supported-lic-types"></a>

Optimize CPUs supports billing based on the number of active CPUs for the following types of license configurations for instances launched from a license-included AMI. For more information about license types, see [AMI billing information fields](billing-info-fields.md).

**License-included AMI instance billing**


| Licenses included | Usage operation | Price per vCPU hour |

## Supported purchasing options
<a name="win-opt-cpu-supported-po"></a>

Optimize CPUs supports the following purchasing options for license included instances:
+ On-Demand
+ Savings Plans

**Warning**  
If you use Reserved Instances, discounts may not be applied when you configure Optimize CPUs for license included instances in the same payer account. We recommend that you use Savings Plans to reduce vCPU-based licensing costs and provide comparable savings on your compute costs.  
Accounts that used both Optimize CPUs and Reserved Instances for Windows and SQL Server on the same instance type before October 15, 2025, were added to an opt-out list to maintain their current billing experience. To take advantage of Optimize CPU license savings, contact the [AWS Support Center](https://console.aws.amazon.com/support/home#/) to be removed from the opt-out list.

## How Optimize CPUs works to save on licensing fees
<a name="win-opt-cpu-how-it-works"></a>

The following examples help to illustrate the cost savings that are possible when you configure your CPU usage.

**Example 1: Default billing** This example shows an r7i.8xlarge instance launched from a license-included Windows and SQL Server Enterprise AMI that ran for 100 hours with the default CPU configuration of 32 vCPUs for the instance type (3200 vCPU hours).

The bill shows one line item with a combined rate that includes both usage and licensing fees.

**Example 2: Optimize CPUs billing** This example shows an r7i.8xlarge instance launched from a license-included Windows and SQL Server Enterprise AMI. To save on license fees, the number of CPUs that are active was reduced to 16 vCPUs. Then the instance ran for 100 hours with the new configuration.

The bill shows the following two line items.

Billing description: **Elastic Compute Cloud**  
The first line item shows the baseline cost of the Windows and SQL Server instance that ran for 100 hours (\$1211.68).

Billing description: **Amazon EC2 Optimize CPU License Included Third Party Fees**  
The second line item covers licensing fees based on the number of vCPUs that were active for the billing period (\$1673.60).

**Example 3: Optimize CPUs billing with Savings Plans** This example shows an r7i.8xlarge instance launched from a license-included Windows and SQL Server Enterprise AMI. To save on license fees, the number of CPUs that are active was reduced to 16 vCPUs. Then the instance ran for 100 hours with the new configuration.

A one year *No Upfront Compute Savings Plan* with a \$11.60/hour (rounded) commitment provides further cost savings that reduce the baseline cost of the Windows and SQL Server instance. The Savings Plan commitment covers the full 100 hour usage of the r7i.8xlarge instance for a Savings Plans rate of \$11.53362/hour.

The bill shows the following line items.

Billing description: **Savings Plans for Compute usage**  
The first line item shows the Savings Plan commitment for the full 100 hour usage (\$1160.00).

Billing description: **Elastic Compute Cloud**  
The second line item contains two entries. The first entry shows what the baseline cost of the Windows and SQL Server instance that ran for 100 hours would have been without the Savings Plan (\$1211.68). The second entry shows that the full baseline cost was covered by the Compute Savings Plan (-\$1211.68), which yields a net cost of zero for this line item.

Billing description: **Amazon EC2 Optimize CPU License Included Third Party Fees**  
The third line item covers licensing fees based on the number of vCPUs that were active for the billing period (\$1673.60).
