Does Hyperthreading cause performance loss in games?

post #1 of 5
Thread Starter 
So I saw someone mention the 2600k is worse than the 2500k for gaming due to hyperthreading headscratch.gif Now I have an i7 920 @ 4GHz and was always told HT won't hurt me, (or help in gaming due to most games not supporting that many cores).

Was this guy mistaken or is he right but only for that CPU and not mine?

You can turn HT off in BIOS settings, so I'd have to say that the claim that HT hurts gaming performance is false. I have observed that in general it seems that you can get a better OC w/ a 2500K than 2600K.

This. HT will not hurt your performance. And, I can get a 4.6GHz on my 2500k at 1.35v, so I guess it overclocks a little bit better too.

I heard a ton of people say that the CPU tries to use it but ending up loosing FPS. If I would have a 2600k or 2700k I would without a thought turn HT off, and forget about it. Btw it makes your temps a tad lower.

It is not worse for gaming, it is just that Hyperthreading will not in any way, shape, or form, increase your gaming experience.

The only thing it will do is possibly cause you to lose 1-2 fps as seen in these benchmarks, but this probably won't happen with most games.

The only thing hyperthreading will do is increase your synthetic benchmarks.
