A new Windows 11 Insider build includes a toggle for Intel’s Advanced Performance Extensions, or APX, a major x86 upgrade that doubles the general-purpose registers. It needs new processors such as Intel’s Nova Lake and software built to use it, so today’s PCs won’t [get a free](https://technosports.co.in/google-play-redeem-codes-get-free-gift-card/) boost.

## What Was Spotted

Windows enthusiast Xeno found the setting in Insider Preview Build 29695.1001, in the Experimental channel for future platforms. It reads “Let Windows use APX for better performance” and needs a restart. [Wccftech](https://wccftech.com/microsoft-prepares-windows-11-for-intel-apx-bringing-potential-performance-gains-to-nova-lake-and-future-amd-cpus/) has the details. Microsoft hasn’t said when it reaches regular Windows 11.

## What Does Windows 11 Prepares for Intel APX

| Feature | Detail |
| --- | --- |
| General-purpose registers | Doubles from 16 to 32 |
| New instruction forms | Three-operand instructions and conditional operations |
| Intel’s estimate | About 10% fewer memory loads, over 20% fewer stores, about 10% fewer instructions |
| Basis for the estimate | Simulations on SPEC CPU 2017 integer workloads, not real-world gains |

## Who Supports It

- **Intel:** Nova Lake desktop and Diamond Rapids Xeon chips are expected to support it.
- **AMD:** Expected to adopt it through the x86 Ecosystem Advisory Group, though its Zen 6 appears to lack documented support and Zen 7 may be first.
- **Microsoft:** Has added APX detection to the Windows SDK and debugging support.

## Frequently Asked Questions

Will APX speed up my current PC?

No. It needs a compatible CPU and software compiled for it.

Which CPUs will support APX?

Intel’s Nova Lake is expected to, and AMD is expected to follow. *Sources: [Wccftech](https://wccftech.com/microsoft-prepares-windows-11-for-intel-apx-bringing-potential-performance-gains-to-nova-lake-and-future-amd-cpus/), [Intel](https://www.intel.com/content/www/us/en/developer/articles/technical/advanced-performance-extensions-apx.html).*

Which CPUs are expected to support APX?

Intel’s Nova Lake is expected to support APX. AMD is also expected to adopt it, though Zen 7 may be the first AMD generation with support.
