Does FSX take advantage of HT?Looking between a 2500k and 2600k.

No, I have a i7 2600k and have ht off because I have noticed it gives me slightly better performance.

Then Ill go for the 2500K since thats the only difference it appears.

Yeah, I have read in many places on this site that if you mainly plan on playing FSX, then the 2500k is a better choice since the 2600k makes no difference in FSX.

How do you turn this off?

Sure in the Bios somewhere.Not very many games use HT at all so think Ill go for the 2500K thanks guys!

um yea ihave the core i7 970 6core with HT on and fsx takes full advantage with proper affinitymask settings. oh and sandybridge is kinda lame

Please elaborate

the 2600k has 8 mb level 3 cache while the 2500k got 6. i cant give you an exact number for the resulting performance gain but it should be round about 10 percent.

I don't know who is right but I have read on Many places on this site that if you plan on pretty much only playing games, especially FSX, the 2500k is for you. From my own personal experience I have turned ht on and used bojote's auto tweaking which put on my cfg the correct affinity mask value you should have with ht on. I did this same test with ht off (and the correct affinity mask) and I got overall 2-3 fps more with ht off. Why? I don't know. I guess it is just FSX's inefficient engine, but what I can say is that is what happened to me.As for sandy bridge, it is currently the best solution for fsx as it can overclock much higher than previous i7's. Also, due to the better architecture, it has even beaten previous gen 6 core i7's, including the 990x, in bench tests.

Get the 2500K if this is just a gaming machine...

Is there a OC guide for best possible results using the p8p67-le motherboard? Im still getting dodgy performance from my 4.5ghz auto overclock using the asus bios. Is there a better way of doing this? Sorry to hijack the thread. Kind of related.

I guess this one is good since it is written by Asus:http://hardforum.com/showthread.php?t=1578110Also, have you tweaked fsx?

Ive got the LE version of the p8p67 so most of those features arent available to me.

Another vote for the 2500KThis should explain why some think FSX makes use of HT:

Hyperthread is not recognized by the FSX render engine. The reason people get confused about HT and MSFS is because the proc has a physical cache for HT virtual cores, therefore FSX (which uses a very lame multicore code) sees the physical cache, assumes its a physical core, and spawns threads but those threads die and do nothing. The CPU meter shows activity but the activity on HT threads with FSX running is quite false.
