Question MSI Tomahawk Max WiFI and the M.2 NVMe slots ?

[Kawdam91]

Hi,

I recently picked up a MSI Z790 Tomahawk Max WiFi and I am not sure if I should have just gone for the none Max model. The M.2 Slot 1 halves your GPU bandwidth down from x16 to PCIE x8 if it is populated, this slot is also the only slot that runs direct to CPU as the other 3 run via the Chipset.

Is there any performance hit running an OS NVMe from a Chipset rather than direct to CPU? I ran some benchmarks and oddly enough I got better results in the Chipset slots over the direct to CPU Gen5 M.2 Slot 1.

When PCIE 5 GPUs release will the top slot if populated cause that generation of GPU to run at PCIE 4 x8 also?

Thanks.

In all honesty, you won't be able to tell the difference with the highest end SSD on the market or the mid tier SSD on the market when it comes to day to day tasks. n fact, I tend to have the fastest drive on the CPU allocated slot to handle high bandwidth needs, while the OS and other apps are on a smaller SSD that's allocated to the chipset.


What processor are you working with?

Thanks for the reply. I have a 14700k. Good to know it's not a massive issue.

I know the performance difference isnt massive between x8 and x16 on the GPU but I would rather run that at its max potential.
