How to test MBP 2018 for possible heat, noisy fan and thermal throttling issues? Let's make tables.

[jinnyman]

I'm wondering which CPU might be the best choice. i.e. CPU which can maintain its base clock speed under full load.
There must be some golden balance! It would be interesting to see if 8750H and 8850H can maintain its base clock speed.

I kinda suspect that 8750H would, but not so sure about 8850H.

I would just get something that can get normal productivity job done silently and put the investment on DIY workstation.

There are a bunch of test you could do. Here are some:

CineBench - especially used for seeing CPU performance in rendering
I would recommend doing the following from idle:
1 run to get a base score, 5 consecutive to get a idea on how it performs when the CPU is warm
Another interesting test would be see the difference when using fan control software set to 100% (app 6000rpm and 5500rpm (left/right)) in the same scenario.

Then there is Geekbench, which also is a great test and much more used. The great thing here is that there is a big online archive with all test date from the free version, so comparing performance on multiple identical devices are possible.
Here the same runs can be done, but seems a little much unless you have a high difference in the CineBench test.

also Prime95 which should hit the CPU hard, but I have not tried that one myself yet, so I am not entirely sure on how it works and how to compare. I will do it later, but if some have more info it would be nice to hear.

For utilities you will need
Intel Power Gadget, this is an amazing tool to see power consumption, clock speed, temperature and utilisation of the CPU.
Some kind of fan control software, my favourite is smcFanControl, last updated in 2016 but I have not encountered any problems with it on a 2017 MBP, so my guess is that it will work fine on the 2018 model.
Noting ambient temperature will also be good as to give an idea on environmental impact.

If anyone have some resources on rendering test in FCPX or its likes that is free to use, we could have a more comparative test across machines as we are testing on identical work mass on different hardware, giving us an easy comparison.

EDIT, note, most fans control software can show current RPM and will allow system to go higher (if possible) then what you set it to if needed

Let’s gather data using different tests and compare results.

The thing with the render time test in After Effects, Premiere and FCP X, is that they should all use the same rendering source (like render the same project) across devices to ensure a uniform test base. I do not know if there are ant where to download such thing, and if the programs themselves can be had in a test period.

I happily contribute with my 2017 15" machine too

There are benchmark render projects out there to test with. I'm curious about the comparison to a 2017, but what I really want to know is how the i7 and i9 compare to each other. What D2D said was that when under thermal load the i9 was slower at rendering Premiere than the i7, which if true is crazy, but I'd like to compare in other applications between the two files.

If you would provide a link to some I will see about doing a test with them

This is also what is most interesting to me, but I do think that it is important to see it compared to the 2017 models too

Yes, i7 vs i9 under load. Does the i7 throttle as much as the i9.

I understand the need to throttle but it could be the i7 runs cooler and therefore sustains workloads better over periods of time.

I would try this one if you can: http://www.mediafire.com/file/qgoacxne6567wxn/AE_Test_2016.zip

I will run it tonight and post my results.

The forum will be interesting for the next weeks as we will se a lot of new threads and not just the same old keyboard complaints (I expect we will still see them, just not for the new MBP)

I hope that the SNR remains high though - too many people that are new to Intel Power Gadget and documented testing will lower the SNR of the forums for a while with spurious datapoints :/

Lisa of Mobile TechReview mentioned about Macs Fan Control. Can anybody please try and let us know how noisy and hot it becomes?

 

[Elektrofone]

Does anyone here have a 2018 i7 model to compare to an i9 model? I am still trying to compare benchmarks of render times in FCPX, After Effects and Premiere Pro between models.

One Japanese user seems to use Intel Power Garget for testing. Anybody tried it?
[doublepost=1532140063][/doublepost]At the very beginning, did they say both i9 and i7 have problems?
