MSI GT75 with i7-9750H and RTX 2070: My Benchmarks and Tests | Review Incoming...

I got my hands on a MSI GT75 with i7-9750H and RTX 2070. I'm currently working on a review of the laptop, but I wanted to chime in on here and post what I've found so far. Also, I wanted to shoutout HIDEvolution for sending this out for me to review!

Preliminary Impressions:
The i7-9750H is a ridiculously underpowered chip for a chassis with this much cooling. Even an extreme stress test, barely brought the average temps up 56/54 C on CPU/GPU. That's insane! With Max Fan off, the temps do come up quite a bit and the fans a quieter. But overall, this machine can run at great temps and low overall fan noise, which is nice. See the image below.

My main complaint about the system is that it doesn't have a desktop CPU. With a chassis this big and thick, the laptop should be able to handle a desktop CPU no problem. I do hope they add that as an option in future generations. [EDIT: The i9-9980HK 8 Core CPU will probably be offered in this model. That one will be unlocked and very competitive with the 9900K chip.]

The RTX 2070 performance has been impressive to say the least. It's really pumping out the frames per second. See the Far Cry 5 benchmark below to see that it's less than 10% behind the RTX 2080, at least in that game, though that game does tend to be limited by the CPU.

6 Cores
12 Threads
Max Single Core Clock: 4.5 Ghz
All Core Clock: 4.0
Full Load Power Draw: 55-60 Watts
Maintains 3.99 ghz steady during stress test



Of course, this is with a thick and heavy chassis with ample cooling, so keep that in mind. This laptop also had its cooling upgrades done from HIDEvolution, including bottom chassis upgrade, thermal pads, and Thermal Grizzly.

I've done a number of benchmarks primarily focused on the i7-9750H. I've included them in this video here:



Here are some quick screen grabs from the video:







The laptop came undervolted by -0.050 stock. Not sure if MSI or HIDEvolution did this. I am assuming MSI did though. The CPU became unstable if I increased the undervolt to -0.080. So this chip was not undervolt friendly, though it doesn't matter much in this huge chassis. You won't get any performance gains since its not being throttled anyway.

I'll add more to this when I can and when I get more thoughts together on the machine!

Cheers!

 

Very nice. Can't wait to see the full review. Always good information to be had.

 

Aren't those temps pretty normal for the GT series? Don't quite know...

 

Thanks for the info. As the for the undervolt, HIDEvolution does undervolt the machines when they customize it or choose to do so when ordering, otherwise they come from factory.

 

Will MSI be doing an i9-9980H SKU this go around in the GT75?

 

Hopefully they do release the extreme edition as they did it numerous times in the past because that would be awesome.

 

The only reason you get such great temps are the hidevolution mods and liquid metal ^^
Stock, you would easily be seeing 90C on cpu and probably over 80C on the gpu (my 1080 in the same chassis went to 90C even). Be happy you made a good decision and got it modded. Trust me, I know what I am talking about as I had the one with 8750H and gtx 1080 totally stock from the factory...

 

This is just a review unit sent by HIDEvolution, but that's good feedback to know. I am honestly shocked. Really, it was that bad? It's hard for me to believe considering there are 12 heatpipes in this badboy. Is 90C on CPU with default fan profile? I am actually really curious and am going to look into this a little more because I am just about to post my review of the unit.

 

I just did some quick checking up on NotebookCheck's review of the previous GT75, and wow, you're right. The temps aren't great with some thermal throttling under a dual CPU/GPU stress test. That's really surprising. I would have thought that this guy would at least stay under 85C with stock everything.

All that said, the tests I have seen so far are on older GT75's. Nothing with exactly the same to what I've got my hands on.

 

Yes, they are doing one, but sadly, they are only offering a 4K screen as far as I can tell.

 

I don't expect any improvement on thermal management. The only things that could make a difference would be lower power consumption/voltage or higher fan curves (though default fan curves on mine were extremely loud... hence I had to undervolt the gpu as well to like 0.9V as else I had the fans spin up to 5000 rpm screaming over my gameplay) Look at the sound readings, the laptop can easily reach 60dB under load according to notebookcheck tests (with the i9 version though - the i7-8750h was much better at least in cpu department). But seeing that gpu fan made the most noise for me even after repasting with gelid gc extreme and correcting the loose screw (yeah that happened in the factory lol).... You get the idea. Only undervolting the gpu made it stay at least around 80C with a little less aggressive fan profile (not making me deaf anymore but still loud).
PS. for reference: my gt75 8rg ate 220W max on the 1080 and 90-100W on the 8750H. But the 1080 generally took over 180-200W mostly as far as I remember stock (220W being the peak). After undervolt these numbers were a whole bunch lower but can't remember exactly how much.

 

Stock voltages and stock paste are very bad. You don't even need a super high end thermal paste, just a good paste job and good undervolting and the difference is massive. Regardless of manufacturer.

I just got a Lenovo P1 that on stock voltage and paste was on the 90 celsius with 10% utilization of the CPU! In this case, just undervolting (-150mv) and I am hardly reaching 80 celisus now on 40% utilization.

In my MSI GS75 I went from 95 Celsius 100% utilization to 82 celsius undervolted and repasted with IC Diamond. the GT series has a beefy cooling system, but the amount of voltage and possibly bad paste job can make you have a bad experience with temps from model to model.
