I'm trying to optimize some software and need to know the layout of my CPU?

+1 You could also check the "CPU" section in HWiNFO, it lists P-cores and E-cores directly. Another option is using PowerShell with the command `Get-WmiObject Win32_Processor` to get core count details. Hope that helps.

Yeah, that's a solid approach. For a quick visual, you can also open Task Manager, go to the Performance tab, right-click on the CPU graph, and choose "Change graph to" > "Logical processors" to see them all laid out.

This happened to me when tuning a game. I used a free tool called CPU-Z to get a clear breakdown of all my cores and threads.

Yeah, I had the same problem. CPU-Z shows the layout, but for real-time monitoring of which cores are active, I ended up using HWiNFO64.

This happened to me too. I found the Windows Task Manager, under the Performance tab, actually labels them as "Performance" and "Efficient" when you click on CPU.

You could also use a free tool like CPU-Z, which shows the exact core layout and types in a bit more detail.

+1 I had the same problem. I used CPU-Z like the other person said, and it clearly labeled the P-cores and E-cores right on the "Cores" tab.

Yeah, CPU-Z is perfect for that. One extra tip: in Task Manager's "Details" tab, right-click the column headers, add "Core type," and you can see it live per process.
