5900X no SMT, has someone tried ?

I've read/watched stuff about this, some claim that it reduces temps with mostly no performance loss, others than it's useless...

 

Has anyone tried and have some results/conclusions ?

The performance of SMT depends entirely upon the workload.

Sure, in my case it's home usage and gaming, my CPU usage never goes over 30%...

That's 60% without SMT 😉

 

But what's keeping you from trying it? You have the CPU already.

Why would you want to turn it off?

As I've said some people claim you can reduce power consumption and temps, but it's a bit out of curiosity too 🙂

Reduce consumption and temps? You will also be reducing performance.. Might as well as just sell it and get the CPU you really want 🙂

I'm happy with my 5900X, and it's so powerful it's never used fully, that's why I suppose I won't lose performance with disabling SMT

But I mostly want to experiment, so asked for advice 🙂
