Choose between the generic and optimized build

Note

This guide only applies to the Linux and Windows versions of Zen.

This guide provides an overview of the differences between the generic and optimized builds of Zen, so you can make an informed decision on which version to use.

Differences between the optimized and generic builds

The optimized version of Zen uses Advanced Vector Extensions 2 (AVX2), a CPU instruction set that enhances performance for certain tasks. This instruction set is available only on modern processors.

Supported CPUs for the optimized builds

The optimized builds of Zen are compatible only with the following CPU families:

• AMD
  • Carrizo
  • Bristol Ridge
  • All Ryzen CPUs
• Intel
  • Desktop and Mobile Processors
    • 4th generation Intel Core and newer (All architectures)
    • Celeron and Pentium Tiger Lake and newer
    • Intel Core Series 1 and Series 2
  • High-End Desktop (HEDT) and Server Processors
    • Intel Core X-series (Skylake X, Cascade Lake)
    • Xeon Scalable (Cascade Lake)
    • Xeon Scalable (Cooper Lake)
    • 3rd generation Intel Xeon Scalable (Ice Lake, Cooper Lake)
    • 4th generation Intel Xeon Scalable (Sapphire Rapids)
    • 5th generation Intel Xeon Scalable (Emerald Rapids)

If your CPU family isn’t listed, use the generic build.

Check whether your device supports AVX2

Linux

1. Open a terminal

2. Run the following command:

   grep -q -i avx2 /proc/cpuinfo && echo true

   The terminal outputs whether your CPU is supported (true) or not.

Windows

1. Open the Settings app.

2. Go to System > About.

   The settings app displays your CPU model.

3. Check the model name in either the Intel or AMD websites.
