I7 6700k question..

[GrendelsDad]

I am new to Intel so please forgive my ignorence.  From what I have gathered Hyper Threading is to be turned off In this sim for best results.  I seem to get slightly better performance with it enabled.  Especially with multiple (A.I.)HE-111's on screen.  So my question is this.  Does Intel implement this in anew way on Skylake that makes this run better than on the older chips?

Really? I'd never heard of any instance where hyperthreading off would help? I may have missed it mind you

 

How are you liking the Skylake setup. I'm thinking of building a Core i5 6600 setup myself.

I wish I we had a "black death" like track to run.  I am running a high resolution so that may have something to do with it as well.  This could be a plecebo but from looking at fps it seems to bottom out around 50 fps where with HT off it dips into the mid 40's.  But with no track its hard for me to tell?  I really like the system.  Plays everything really solid.  I will say that at my resolution my GFX card is stressed to 80-99% while playing and that's what leads me to believe that its the HT making a small difference.  The chip overclocked easy as can be and that was a noticeable difference in IL2 for sure.  I thought that HT on was unusual from what I have read around here.  I think you will be very pleased with an i5 if you go that route.

Hyperthreading is meant to minimize the effect of stalls in parallel computations. Stalls can happen for instance when a task needs data that isn't in the cache. When one task that happens, another task on the same core starts executing. When the second task stalls, the second can continue executing, because by then it should have recovered from the stall (the data it requested has arrived from memory). This however requires larger amounts of shared resources (caches), since two tasks are sharing these resources. If you have an i7 and disable hyperthreading, the one task per core now running has additional resources available.

 

If an application does not take advantage of parallelism, hyperthreading is of no use, and turning it off could help. IL-2 BOS does however take advantage of parallelism to some extent, so it's not clear that it would benefit from turning off hyperthreading.

I think you can replay a track and it takes the same demand as live play. Maybe test that out for consistency. It's an interesting experiment.

I have a 4820k processor, and disabled hyper threading some time ago. For games it just really does nothing for them, heck most games at best only use 2 cores to start with , much less using any of the  virtual cores hyperthreading would give...

 

Now I don't know for sure if I get better performance in my games, sometimes I think I might but who knows. I do know my cores stay a little cooler with it disabled, and I can get a more stable little higher overclock with it disabled.

 

Hyperthreading is good for heavy computer tasks that make use of it, like heavy  video processing, etc.

 

But it certainly does not hurt anything having it enabled, and if the OP seems to get better performance with it then I say go for it.

PimpSauceGrendelsFather, keep HT on. Why waste the value of it.

 

BTW, 4.8Ghz? My goodness, that's fast! You have a TOP NOTCH system!
