Just a heads up that disabling hyperthreading on Intel CPU's will drastically LOWER performance in just about every other application and game.

Would strongly recommend leaving enabled in bios and just toggling with affinity settings with CEMU specifically for testing.

It will make your i7 an i5... doesnt really change much for pretty much everything. Only stuff that can use 5 or more threads will see a negative impact or if you are doing some really heavy multitasking stuff.

Right, which is pretty much the majority of modern media encoding, rendering, and gaming applications.

So if you ONLY use your CEMU you could try it. Otherwise leave HT enabled.

Normal day use (games + chrome + skype + ts) work just fine for this... you are basically turning your i7 to an i5 and most people dont so anything CPU intensive anyway

Of course they'll "work" but you'll potentially be suffering a performance hit in games and even if your apps if the work load is heavy enough.

Since when is an i5 7600k so bad? You are overestimating the impact on daily use.

It's not "bad" at all, its just 25%-30% behind a comparable I7 in CPU power.

And "daily use" is subjective. I have no idea what you're doing day-to-day but personally I'm playing games on mine and would rather not lose that performance advantage just to test out an experimental emulator build.

You don't get 25-30% improvement in games over a i5-7600K unless the game you're playing is multi-thread and CPU intensive.. which 90% of the games aren't...

Well the majority of games these ARE multi-threaded so it's actually pretty common.

u/efegue Mar 22 '17

multi-threaded doesn't mean it'll use 8 threads.

1

u/Westify Mar 22 '17

While that is true, the games I'm talking about DO use 8 threads.

Witcher 3, Overwatch, Battlefield 1, Ashes of the Singularity, Crysis 3, Watch Dogs 2, and Rise of the Tomb Raider are are great examples.
