@iieeann How does the thermals on the system look at idle or minimal load? Have they improved the cooling solution so the keyboard doesn't get too hot to work with?

 

I would say it is not improved in that regard. It uses the same cooling solution and fan tables. With the system repasted, and the performance mode set to "Cool" to force the fans on, the CPU is around 45-50C and keyboard I guess is around 30C, with 21C ambient temp.

Yeah my Timespy results are running default settings. You may want to monitor temps on yours to see if it reaches 87C on the GPU which will trigger short throttles which can lower the score.

 

https://www.3dmark.com/spy/38088494

GPU temperature not more than 74C, CPU no more than 78C.  During CPU test alone is 100C. 

Both my GPU and CPU scores are lower than yours, especially CPU.

laptop alone means without dock.

Power profile is default balanced.

Ok, I think power is limited somewhat in balanced / optimized, so you might want to try "Ultra Performance" and see if it improves. I would expect your system to get around 17k in Timespy Graphics at around 135-140W.

 

Also if possible you could contact 3dmark support and ask them to whitelist the RTX 5000 Ada GPU as it is new and hidden by default. You can check if they fixed it by opening the link you posted in an incognito window.

I have enabled Ultra Performance profile and run the benchmark but the result has no difference.  Tried Nvidia GPU only mode still the same.

Could it be Win10 Pro is actually better for 3dmark GPU & CPU test? 😐

I tested both stock Windows 11 Pro OEM install (by Dell) and also a clean install Windows 10 Pro which basically test the same for GPU score. For CPU score Windows 10 Pro is indeed superior.

 

Do you have VBS/HVCI disabled in Windows 11, and Turbo Boost 3.0 disabled (allowing GPU Dynamic Boost) in the bios, and GPU Memory ECC disabled? Those could potentially effect performance. You would probably want to run the test while recording GPU Power used, to ensure its using 135-140W under load. There is a small variance in silicon quality but I would suspect that at the same TGP and temperature an RTX 5000 Ada should always be higher performance than a RTX 4000 Ada.

 

I will say that I would not be surprised if there is a Dynamic Boost bug as those have existed in the past models, 7770 for instance with 3080Ti could not go beyond 130W without overriding power limts using certain drivers, despite being advertised as "150W TGP" in Nvidia Control Panel.

I just installed Win10 Pro on an unused ssd and run the test.  Bios setting unchanged.  The result difference is huge.

 

Win11 15573 - GPU 15912, CPU 13899

https://www.3dmark.com/spy/38208390

 

Win10 16873 - GPU 16797, CPU 17318

https://www.3dmark.com/3dm/93785961

 

For Win10, GPU is 8.3% faster and CPU is 24.6% faster (this is too far off!)

 

I haven't tried VBS/HVCI and Turbo Boost 3.0 thing, but i don't think that is the issue.  default setting without changing anything in Nvidia control panel and power profile, the difference is just too difficult to accept.  Not sure what is wrong.

[Aaron44126]

VBS is an interesting one to look at; they are probably turning it on by default on new Windows 11 systems coming out of Dell but it would not be turned on by default on a new Windows 10 install.  It's in Windows Security, "Device security" (on the left), then "Core isolation details".  Turn off "memory integrity" and then you will have to reboot.

 

Microsoft even recommends disabling it for top performance.

[iieeann]

If it is about memory integrity, it has been turned off because my old Logitech G19s keyboard driver won't load otherwise.

 

Both OS are using Dell nvidia driver. I noticed if nvidia website driver is used, under nvidia control panel the "display mode" tab (when using laptop alone) will not be there. It is where user can select either automatic/optimus/nvidia only.  Whatever chosen will not affect 3dmark score anyway it is more for battery saving.

[Aaron44126]

Now I'm sort of curious if you did your own clean Windows 11 install, if it would behave more like Dell's Windows 11 install or your clean Windows 10 install.  I agree, the performance difference is crazy.

Just got an unused 2230 ssd to install win11 from zero.  All other ssd removed. After driver & windows update 1st program installed is 3dmark.  Not touching graphic and power profile settings.

 

With memory integrity ON,

Result = 15814.  GPU 16146, CPU 14165

https://www.3dmark.com/3dm/93836345

 

Disable memory integrity and restart PC,

Result = 16236.  GPU 16627, CPU 14332

https://www.3dmark.com/3dm/93836926

 

So disabling memory integrity in this case improved GPU score slightly and for CPU basically no difference.  I would say in this fresh Win11 the GPU score is 5% better than earlier Win11 (not far from Win10), but CPU score remains the same, far from Win10 CPU 17318

 

Out of interest i change from RST to AHCI and run the test.  There is no impact to the result.

Result = 16184. GPU 16527, CPU 14482

I searched around the web and found a number of people point out Win11 22H2 is the culprit.  Older Win11 21H2 has similar performance as Win10.  Hmm where to find 21h2 bootable usb...

Here are some links for old Windows ISOs.

https://isofiles.bd581e55.workers.dev/

https://tb.rg-adguard.net/public.php

 

Windows 11 21H1 (build 22000) is only supported until October 2023, unless you have Enterprise/Education edition, then you get an extra year.

[iieeann]

Used Rufus to create bootable Win11 21H2 and install. The result indeed is closer to Win10

 

Memory Integrity ON

https://www.3dmark.com/spy/38310340

Result = 16229. GPU 16227, CPU 16532.

 

Memory Integrity OFF

https://www.3dmark.com/spy/38316514

Result = 16360. GPU 16249, CPU 17026.

 

Memory integrity has slight impact on CPU.  Compared to Win10, both GPU and CPU are lower but the difference is not much.

 

So it is confirmed that Win11 22H2 is causing big CPU performance impact.  Better to stay with 21H2.

New BIOS. 1.2.2

 

https://www.dell.com/support/home/en-eu/drivers/driversdetails?driverid=m060g&oscode=w2021&productcode=precision-16-7680-laptop&lwp=rt

[iieeann]

This is to confirm that the WWAN slot can support up to Gen3 x2 b+m key 2242 NVMe SSD (x3 and above will not fit).  The best possible ssd could be WD SN520 but max capacity only 512GB.  I bought a never seen brand "Kingspec" 1TB SSD with advertised speed lower than SN520 but i need the capacity.  Upon installed, the sequential write performance of this SSD is very disappointing.  Copy 250GB image file, average speed is only 250 MB/s (Switching between 100MB/s and 680MB/s every few seconds depends on cache)  vs advertised speed of 1000 MB/s.  I am not absolutely sure if this is because of the limitation of the WWAN slot.  The price is cheap anyway.

 

The SSD at WWAN slot cannot be detected in the bios, so it is not bootable.  Another important thing is that the SSD must be formatted before installing into the WWAN slot.  A brand new SSD will not be detected in the windows.

Hmm, I have problem updating bios either by running the exe file; or using Command Update; or running F12 when start up.

Command Update will return update failed message.

Running exe file just stop at page below:-

 

 

Press F12 during startup and select update bios by choosing exe file, nothing happened after that.

Current bios version is 1.1.0

Does that mean my bios is corrupted? I still can enter bios to do any setting.

I downloaded .rcv file too but not sure how to use it, it is for bios recovery.

I tried download older bios 1.1.0 to install and yet the same thing happened, so the 1.2.2 exe file is not corrupted.

[win32asmguy]

@iieeann I would suggest resetting to factory defaults in the current bios and then trying again. If it still does not work maybe try removing bottom panel, disconnecting the battery and then holding the power button for 30 seconds (they call it draining residual flea power).

 

Dell does have this "force a bios update" process, but ideally the normal process would work first:

 

https://www.dell.com/support/kbdoc/en-us/000134938/forcing-a-bios-update-without-the-ac-adapter-attached-on-a-dell-laptop

[iieeann]

I am not sure if this is because of me overwritting the earlier W11 22h2 partition with 21h2, the dell bios recovery is broken and i did not install dell bloatwares back. I only have command update.

 

I still have the old 22h2 image together with boot partition.  I will restore it and try if bios update will be back to normal.

Hey folks, just a query: do the Dell Precision 7000 series force use of Windows Modern Standby and remove S3 sleep from the BIOS? I bought a Precision 3470 as a backup to my HP ZBook 16 Fury G9 and I have been appalled by Modern Standby overheating the laptop and killing the battery while sleeping. Disabling Modern Standby in the registry removes the ability to sleep the laptop completely. Thanks in advance for any input.

Pretty sure Intel also killed S3 sleep in all newer CPUs, but yes, S3 is gone in 7680 etc.

Confirmed, no S3 sleep in Precision 7560 or Precision 7770 here.  Attempts to force it back on have not been successful.  (You can edit BIOS variables and Windows will show it as an option, but it still won't work right.)

I'm testing the rtx 2000, 3500, 4000, and 5000 versions of these laptops at work.  Does it seem the chassis is limited in power delivery between the 4000 and 5000 card?  I'm not seeing much difference in performance running basic testing I have and they both max the power adapter out testing with a killawatt. 

 

Also, if the docking station solution is going to limit power 30w even more this may be even worse.  I'll try to run testing on this today.

This is normal and has been for the past several generations.  If you check in NVIDIA control panel "Help->System Information" you will probably see that the power limit is the same between the 4000 and 5000 cards.  Performance could be better with the 5000 GPU if you are doing something to take advantage of its extra capabilities (more vRAM, more tensor cores, ...), but otherwise there is no reason to expect it to be much "faster" than the 4000 GPU.

[heikkuri]

@iieeann did you manage to update the BIOS? If not use command line. It also creates log file.

 

Precision_7X80_1.2.2.exe /? will show the options and  few examples.

 

Dell graphical BIOS interface has some problems since one month or more. In some cases it's impossible to type BIOS password because the text box is missing. But you connect with Remote Desktop to same device and then manage do the BIOS update.

 

I know the pictures are from wrong model but the case is pretty much the  same for all Dell Precision and Latitude what we have.

Good old days when BIOS update was piece of cake. I did remove the service tag from all pictures.

 

 

Blue windows top bar has not any text. No more model picture or previous BIOS version on the left

Bitlocker warning text is just box with check mark

 

 

This is my favorite. Simplified minimal interface.

 

 

This maybe a best one. Just click the Update button below if you can find it.

If you had recommendations to dell what would you say?  Add a usb c port for 240w power delivery and a thunderbolt 100w so we could get 320-340w chassis?  I'm not really sure what options are feasible right now but we are a partner and I can give feedback.
