Slow Performance - XPS 15 7590 (i9, 32GB, 1TB)

I'm using my Dell XPS 15 7590 for about a month and since the beginning, the performance was just "okay".

The laptop I have been using before the XPS was Asus Zenbook 15 (i7 8th gen, 16GB, 512GB) and in such a weird way that laptop was much faster at booting up and at doing regular tasks.

I am using Windows Update and  SupportAssist for updating the software, right now got one update that keeps failing which is the SSD firmware update.

I would like to investigate deeper into the performance of the laptop and understand why it runs like that.

I would like to emphasize again that the performance is notably slow, every person that observes the laptop asks why it runs like that.

Help would be appreciated, let me know if you need any other details.

Re: Slow Performance - XPS 15 7590 (i9, 32GB, 1TB)

I read that this model suffers from thermal issues so gpu and cpu are throttled.

GPU throttling is solved in latest BIOS update 1.2.3, and for CPU only solution I've seen is undervolting using Intel XTU tool. Google it, lots on it

Seems a bit extreme for a top laptop..but the old chassis design has reached its thermal limits, negating benefits of the latest and greatest CPUs

Welcome to the Dell Community   

Create a new folder on your desktop named “Firmware Update”

Then download your SSD update.

Toshiba Solid-state Drive Firmware Update for KXG60ZNV256G / KXG60ZNV512G / KXG60ZNV1T02

https://www.dell.com/support/home/us/en/19/drivers/driversdetails?driverid=7ry97&oscode=wt64a&produc...

Copy the update to that folder you just created.

Close all Windows and Apps you may have open.

Go to the folder and right click on the update file and “Run as Administrator”

Best regards,

Re: Slow Performance - XPS 15 7590 (i9, 32GB, 1TB)

@ShaharZwick there are many possibilities, both hardware and software, that could be causing performance issues.

To get a greater understanding, can you help me out with the following details :-

a) Can you define exactly how the system is slow i. opening applications, browsing the internet, frequently hangs, delays in typing etc
b) Does the slowness occur when the laptop is plugged in or on battery?
c) Is the system running hot at all?
d) Have you set the system to maximum performance when it is plugged in?
e) Have you set up the dedicated graphics cards to use each application?
f) Are you running the latest drivers and BIOS apart from the firmware update that wont install?
g) Do you get any on screen error messages or bluescreens during use?
h) Has the system run slow since you set it up?

Can you manually install the SSD firmware and let me know if it improves the performance - https://www.dell.com/support/home/us/en/04/drivers/driversdetails?driverid=7ry97&oscode=wt64a&produc...

The details indicate Improved the performance of the solid-state drive (SSD) on new processors.

Re: Slow Performance - XPS 15 7590 (i9, 32GB, 1TB)

Thanks for the reply @Dell-Alan D.

a) Booting up, opening explorer and applications, hangs, delays and during video playback on the internet. Pretty much all of what you mentioned.

b) Both, but I mainly run the laptop plugged in.

c) It would get very hot quickly, I undervolted the CPU (Core and cache) as shown in the attached image and it still gets hot (less though):

d) True, maximum performance when plugged in, in addition - Dell Power Management is set as shown below:

e) Nvidia GeForce GTX 1650 is the preferred graphics card for all the applications.

f) Yes, got all drivers updated (including SSD firmware), here's a Dell Update screenshot:

g) I've had a few bluescreens during use and during restarts. Although since November Windows Update it stopped occurring.

h) As I said, mainly yes. It's notably slow compared to other systems with lower specifications.

Thanks for the advice @jedpause.

Undervolted the CPU using ThrottleStop, already seeing better temperatures.

Re: Slow Performance - XPS 15 7590 (i9, 32GB, 1TB)

@ShaharZwick those temperatures look normal therefore I don't believe the system is overheating.

I would always recommend running the system on Maximum Performance rather than balanced and see if that makes any difference.

When you use this system and you mention it becoming hot quickly, where were you using the system?

I would recommend running the stress test online and seeing if any errors are returned - https://www.dell.com/support/home/us/en/04/product-support/product/xps-15-7590-laptop/diagnose

If the system has been bluescreening and running slow from when you got the system that would suggest to me that the problem is with Windows itself. Have you tried a Windows refresh or rest on the system - https://www.dell.com/support/article/us/en/04/sln297920/reset-or-reinstall-windows-10-on-your-dell-c...

You have compared the laptop to others with lower specs, have you compared your results to others with identical XPS systems?

Re: Slow Performance - XPS 15 7590 (i9, 32GB, 1TB)

Thanks again @Dell-Alan D, here are some more details:
I am running the system on Maximum Performance, temperatures went up to 80 degrees minimum when idle (Chrome opened):

Ran a full stress test and got no failures.

Unfortunately, I haven't compared my laptop performance to other identical XPS systems.

ShaharZwick,

 

Thank you for the update. Are you planning on comparing the system to other XPS systems?

@DELL-Jesse L Sadly, I do not know other people with the XPS as mine to compare with.

The closest and most detailed review that I found online is: NotebookCheck Dell XPS 7590 Review 

Support directly from Dell or someone with the same system here in the community would be appreciated.

As of right now, I don't know what else to do. I hope the subject will be addressed by Dell for future support and updates to this model which lacks performance.
