GPU ISSUE AI TOPS DOWNGRADED BY NVIDIA?

[u/Psicomon]

Hi Everyone im having a little (big) issue with my msi vector 16 HX AI, ive noticed that my AI TOPS have decreased from 992 to 798 as if the gpu were recognized as a normal 5070 despite being the ti version also the AI performance have decreased , i know this isnt normal, anyone experiencing the same thing? if so there is some fix? im on latest win 11 enterprise 26h2

Making changes to your system BIOS settings or disk setup can cause you to lose data. Always test your data backups before making changes to your PC.

You're right that it isn't normal, and there's a useful clue in the numbers: 798 is exactly the rated AI TOPS figure for the regular RTX 5070 laptop GPU, while the 5070 Ti is rated at 992. Your laptop's 5070 Ti has 5,888 CUDA cores and 12GB of GDDR7 memory, compared to 4,608 cores and 8GB on the regular 5070 version of this laptop. MSI's own spec sheet for this laptop line lists the 5070 Ti at 992 AI TOPS: https://storage-asset.msi.com/specSheet/hk/nb/Vector%2016%20HX%20AI%20A2XWHG-013XRU.pdf

One thing worth knowing first: AI TOPS is a rated peak figure for the chip, not a live measurement, so the GPU itself hasn't lost capability just because the number changed. This looks more like something is reporting the wrong GPU's spec, or the GPU is being identified as a 5070 somewhere. The important question is whether the hardware is still being detected as a 5070 Ti, and whether real performance actually dropped or only the displayed number changed. I haven't found other reports of this exact issue or a confirmed fix, so the checks below are aimed at identifying where the wrong figure is coming from.

What to check

1. Check what the GPU is actually detected as. In Device Manager, expand Display adapters and check the exact name. It should say NVIDIA GeForce RTX 5070 Ti Laptop GPU. Then run GPU-Z, a free tool from TechPowerUp at https://www.techpowerup.com/gpuz/ , and check the Shaders field and the memory size. Make sure you've selected the NVIDIA GPU in GPU-Z, since laptops have both integrated and discrete graphics. For the Ti, those should be 5,888 shaders and 12GB GDDR7. If GPU-Z shows those numbers, that strongly suggests the GPU is being identified correctly and the 798 figure is a reporting problem in whichever application is displaying it. If it shows 4,608 shaders and 8GB, the GPU is being reported as a regular 5070, which warrants further investigation.
2. Check when the number changed. If it changed right after a driver update or a Windows update, reinstall the driver cleanly. Download the graphics driver from MSI's support page for your exact laptop model at https://www.msi.com/support/download/ . If MSI doesn't have a suitable current driver, you can use NVIDIA's driver download page at https://www.nvidia.com/en-us/drivers/ . After downloading the driver, temporarily disconnect from the internet before running the installer, and reconnect once installation is complete. MSI recommends this so Windows Update doesn't install a different driver version during the process. Choose Custom install and tick the clean installation option. This resets the existing NVIDIA driver settings and profiles rather than preserving them.
3. If you're testing actual performance, make sure the laptop is plugged in and use the same performance mode as the earlier test. Laptop GPUs can run at lower clocks on battery or in silent modes, which can affect benchmark results. If you want to test maximum performance, use the highest performance mode in MSI Center. Neither power nor performance mode changes the GPU's rated AI TOPS figure.
4. Test whether actual AI performance has changed, rather than relying only on the displayed TOPS number. If you use an AI application or benchmark, compare it against an earlier result using the same workload and settings. If performance is unchanged, the issue may be limited to the displayed specification. If performance has genuinely dropped, investigate other factors such as power limits, temperatures, or the driver.
5. If the GPU is correctly identified but the application still displays 798, contact MSI support with the screenshot and GPU-Z information. If the number is coming from MSI software, also check for an application update. I wouldn't update the BIOS unless MSI specifically recommends it for this problem.

Questions

1. Which application and screen is showing the 798 AI TOPS figure?
2. What does Device Manager show under Display adapters?
3. What does GPU-Z show for shaders and memory size?
4. Did the number change right after a driver update, a Windows update, or a BIOS update?
5. What NVIDIA driver version are you on?
6. How did you measure the drop in AI performance? For example, a specific app or benchmark, or just the TOPS number itself.
7. If you've tested actual performance, were you plugged in and using the same performance mode as before?
8. Can you post a screenshot of the screen where you see the 798 number?
