Why is my mid-2015 15" Top Spec Macbook Pro under-performing?!

post #1 of 16
Thread Starter 
Ok I give up.

To save my life I can't figure out why my Macbook Pro is under-performing?

I think his picture speaks for its self:


The CPU doesn't reach anywhere near its native clock speed OF 2.8Ghz whilst running cinebench.

I've also seen this computers GPU do 61 FPS in OpenGL.

I tested Cinebench again a 10 mins after I ran it the first time and it did this...


What's going on?!

Any advice?

Thanks,

The cooling must be insufficient.

My 6700HQ does not throttle and is able to maintain the turbo boost to 3.1GHz on all cores even in prime95.

In my experience, its the U or ULV models that throttle no matter what.

Just read up on it. Wow... Sucks to be me right now. Thankfully I only use this computer for business purposes. Then again that's one thing... But that 2nd Cinebench score is another?!!

Strange my low end 15" rMBP scores not too bad for what it is. The only difference I see if that I'm testing in osx and you were using windows.

Run throttlestop, undervolt using fivr control, set multipliers on overclock to highest allowed per thread usage

Should mitigate SOME throttling issues
