[Sandy B.] How do you guys like Turbo 2.0?

post #1 of 14
Thread Starter 
I think it's great although it can be improved. Every GPU benchmark sees higher scores using fixed multiplier. Not much higher, but in some cases Turbo 2.0 can cause a 5% FPS loss (Unigine Heaven 2.1) probably due to clock ramp up time delay.

It would be awesome if Intel either:
-released an application that can lock CPU at turbo speeds from Windows for benchmarking, like an on off switch, it sucks having to go to BIOS every time I fancy a quick 3dmark11 run
-put a longer delay on when the cpu is allowed to switch back to idle clocks so it doesn't downclock between 3dmark tests <-this would be easier as it can be ninja'd in the CPU microcode

All this is heavily outweighed by the fact that having Turbo 2.0 up can add a couple of years to the CPU lifespan, especially on a machine that's up 24/7 so I can't argue it's benefits. It's the first time I've seen advanced power saving features implemented in such a way that it complements overclocking so it's a huge leap from previous generations.

Sandy Bridge uses Turbo 2.0 to idle at 1.6Ghz and 6 watt usage and in your case load at 4.6 ghz.

Previous generations were stuck at overclocked speeds. They DID come with power saving features, but they were not viable for overclocking.

It can for Sandy Bridge, that's the point of this topic. Nice try tho, your trolling could use some work bro

Its a great feature i havent even bothered to overclock or get an aftermarket cpu cooler because my cpu/gpu crush all my games w/out issues. What i like is when im in class and leave my computer it uses no power which is great for my pocket. What else is awesome with this feature is if you leave your computer on for remote connection it keeps the power down as well.

On the contrary, many people turn on their speedstep and C-states after they've stabilized their clock speeds. This has been the case since C2D, it's not new.

I guess I stand corrected. I thought it was only an option when overclocking under 4.0 ghz although I might have that mixed up with AMD thuban

I have Turbo, EIST, C1E, C6 and C3 states all enabled at 4.8. On my prior X6 1090T, I had Cool and Quiet and AMD C1E enabled at 4.1GHz.
