Question AMD FX 8320 (obviously has 8 cores) doesn't have 8 cores?

[iiSlashr]

So I've had my PC for a while now, and have a pretty garbage 8320. It's self-overclocked to 3.67, I did not do anything to it myself. I figured I'd check out what kind of usage/specs it actually had and noticed this.

Sorry for the Discord link, had to use some kind of link to attach image.

If anyone knows how to fix it, please hmu.

Thanks!

amd bulldozer cores are grouped in pairs, each 2 sharing a fpu compute unit. imagine it like the intel hyperthreading but a bit better.

There is nothing to fix there. Each core block has two integer pipelines sharing one float pipeline, which straddles the line between multi-core and multi-thread. Some tools report this as 4C8T, others as 8C8T.

I strongly disagree with this "being like hyperthreading" since in HT/SMT, both threads share just about everything other than the program counter. On dozer though, the integer pipelines, schedulers and L1 data caches are completely independent, that's almost a whole separate dedicated INT core and Steamroller also added dedicated instruction decoders, only things shared between the two INT cores are the fetch unit, L1 instruction cache and L2 cache.

BTW, never use auto-overclock, it almost always uses far more voltage than it should.
