hyperthreading on or off - Page 2

post #11 of 30
ya, just play gta 4 with ht on it makes a difference dont know why though(coz gta 4 only uses 4 cores),but it might be due to the fact that windows too distributes load among the threads....
and even as someone said above i felt perf. difference in day to day multitasking......

Haha very true, but i'd rather run 5Ghz with HT on than 5200 with HT off drum.gif.

Actually with current software 4x5.2 is better than 8x5.0 unless you have lots of everything running.
Untill OS and games start using 8 cores (everything is optimized for Dual core now) you can use the additional 200mhz with HT off.

At those speeds the performance gain just won't be noticeable. Those 200Mhz will just not be worth loosing the HT functionality.

i like HT off, i get SLIGHLY higher FPS in games, cpu runs 10C cooler, require -0.04V less than with HT on and i can overclock higher with the same voltage. It has been proven that 200mhz is way better if you are a gamer than HT on. Think about it, people make it seem that you only have 1 core. You have 4 physical cores for multitasking, nothing like webrowsing, listen to music, using word processing, etc max out 2 cores and you have 4. HT only help in video encoring, decompressing etc but nothing MOST people will be using in their basic days.

2600k is not a 2500k with HT but people make it seems that way. just like the same with E8400, E8500, E8600, q9550, q9650 etc. all of them where a little higher in price because it has higher clock and little change in the multiplier. well guess what, 2600k also has higher clock and bigger cache than a 2500k. Would you notice the different..... probably not, but did people who bought a q9650 for $300 more notice the different from people who bought the q9550 aswell? they didn't. (only in benchmark). 2600k will always have a better resale value than the 2500k.

I tend to agree that if you plan to leave HT off, then there's really no point in the 2600k. Then again, you could warrant its purchase by claiming a larger cache size over the 2500k.

That is about 10-15 threads total, each (or at least most) doing something intensive

Does your wife not live in the same house?

I have HT off, but I'm only a gamer. I used to play around with video editing and I did just fine with worse hardware so I ain't lost nothing by turning it off.

Well after this thread I turned mine off and didn't notice a difference if BF:Vietnam, still getting 60-80 fps. weird thing is The first time I turned hyper-threading off it lowered my speed to 3.8 but this time its stayed at 4.
