10.10.3 did wonders with my 5K iMac

[cynics]

Both my systems I thought felt a bit quicker after the update. After a few days I either got used to it or they went back to where they were. Which in my case wasn't bad compared to what others have reported.

What is the temperature like when doing general day to day work on the iMac 5K with 10.10.3? I'm wondering whether I should hold off for the iMac 5K 1.1 or whether the drivers have matured enough that the GPU is running cooler. The reason why I'm concerned is the benchmarks making their way around the web have it getting up to a blistering 100+ degrees celsius and I'm hoping that a combination of optimised drivers and the non-intense work flow (apart from the occasional bit of video compression that purely uses the CPU) will mean that it is runs a lot cooler. I'd love to hear someone who uses it on a regular basis on what it is like in 'the real world' vs. the synthetic benchmarks that are doing the rounds.

i got the i7/295x running 10.10.3

with normal non-intense use (internet etc.) GPU is around 50 degrees Celsius, CPU around 40 degrees.

Watching a 720p youtube video in fullscreen for a few minutes brings the temps up to GPU:63, CPU:45 where it then stays - the fans never speed up in that scenario.

hope that helps...


after the update i have not seen any stuttering using mission control. There used to be some when mission control was first evoked.

On my base model iMac I got the following temps before the update. I haven't had a chance to run this after 10.10.3. Ill try and do this tonight.


42C GPU - Idle
50C GPU - watching YouTube video 1080p for 3 mins

So I'll guess that the GPU only really hits the high temperature when running a game full screen at max resolution?

Yes, i think so. Nothing I did so far could bring it up that much. But I don't game and don't edit 4k video.

I got the cpu temp up high encoding video though.

Some people are never satisfied.

Even though you are dealing with a billion dollar company, I think you end up with many times is massive pressure on the engineers to push these devices out on extremely tight deadlines. Add in the secrecy and limited testing because of it's secrecy issues like this are bound to pop up.
