System Report does not accurately report the speed of nvidia cards. CudaZ does and so do some other benchmark utilities like opencl_oceanwave

I think so. Do you know any good way to test it?

MacPro4,1 is limited to PCIe Gen 1 with the NVIDIA web driver, it only enables Gen 2 on MacPro5,1 systems(*).  The only solution for MacPro4,1 is to get your card flashed with an EFI from MacVidCards.

(*) My understanding is that enabling this involves some hackery on the driver's side of things, and NVIDIA only seems willing to do that on the MacPro5,1.

MacPro4,1 is limited to PCIe Gen 2 with the NVIDIA web driver, it only enables Gen 3 on MacPro5,1 systems(*).

MP4,1 and 5,1 are the same machines with different firmwares. Other computer companies to the same but are changing only revision number, not the whole identifier (HP Z800 rev1 and rev2 - different CPU support - familiar?).

Having said that, they use same chipset in both machines, X58 for single and 5520 for dual Xeon configuration https://en.wikipedia.org/wiki/Mac_Pro#Specifications
and support only Gen 2 PCI-e interface. Don't know where did you get gen 3?

CUDA-Z is reporting correct bandwith, so i wouldn't worry too much.

Sorry, I meant Gen1/Gen2.  I think the NVIDIA driver basically looks to see if it's a MacPro5,1 and then does something to the system to force Gen2 to be enabled.  For whatever reason, they do not do this on MacPro4,1 systems.  I edited my post to clarify this, sorry for the confusion.

If 5GT/s in CUDA-Z, then everything is fine.

Oceanwave is not that accurate. The negotiation speed seems dynamically adjusted. So, Oceanwave sometimes report 2.5GT/s, sometimes report 5GT/s.

And system report is quite cosmetic. It often can't properly display the info about the users upgraded items. Apple didn't expect us to do that.

A bit off topic but . . today I disabled beam sync with Quartz debug.

I hadn't realised how much of a hit AA has on FPS !

With my HIS HD 7950 installed Ocean Wave shows 539.5 fps with AA "OFF" ..

 . . it shows 61.7 fps with AA "ON" !

Still the link speed looks pretty good.

The GPU family 1 V3 report in your screenshot indicates Metal 2 is supported.
The only app I know that requires Metal 2 is DiRT Rally. I'd be curious to know how the recent nVidia cards perform on this game. It's a bit slower on macOS than Windows (16% slower) on my radeon 580, without AA (AA hurts performance a lot on the Mac). I believe the difference will be greater on nVidia, as Metal drivers are not very good.
