New Mac Pro (7.1)

Latency is hard to measure precisely without the tools to measure it. I realised that, as what I'm describing I notice when, say, Cmb-Tab'ing or scrolling (and it's subtle, it's not unusable by any stretch) it could also be on the input side. I enabled "game mode" on the monitor and used SwitchResX to reduce the bit depth. Maybe it's a bit better? Maybe not. I feel (much like audio latency) without objective measurements it's probably best not to think about it :)

Edit: things that appear to have helped with perceived UI latency:

* reducing bit depth from 10bpc to 8bpc with SwitchResX (I also made a custom display override for my LG display cloned from the UltraFine one)
* using DPAM (DisplayPort Alternate Mode) USB-C adapter rather than Thunderbolt to DisplayPort
* setting "Reduce transparency" in Accessibility settings
* removing desktop wallpapers, disabling animations, etc (the usual)

So what the config? All of these configurations have the same size rams chips?

Updated GeekBench scores with DIMM configurations, sorry I left this out before.

• 128GB (4x32GB) – 1132/14936
• 144GB (4x32GB+2x8GB) – 1131/14928
• 160GB (4x32GB+4x8GB) – 1141/14684
• 192GB (6x32GB) – 1129/15677

Interesting. Thanks for posting that.

So Apples’s claim that the best performance comes from 6 chips or 12 chips of identical size seems to be corroborated by that test. Although not at all to the single core scores. Only multi core.

How is everyone handling video, specifically picture for post production? Feeding projector via HDMI from graphics card? My current system is using an AJA Kona LHi, but me thinks that won't work in the new Mac Pro. Would love to hear from anyone who is up and running with picture.

Thanks!

Long time AJA Kona User here,
but for the Mac 7.1 is switched to a Blackmagic UltraStudio HD Mini,
as the Kona was giving me headaches.
I didn't`t have any problems at all so far with the UltraStudio!!

Also the UltraStudio with its TB3 Port is giving me the luxury of an extra PCIe Slot.

I hope it works. LHi user here too. I'll find out when my new MP gets here in a week or so.

I reached out to AJA, and all they said was "the cards that have been tested are listed on the website". They didn't answer my question specifically about the LHi.

Yeah, and I guess it depends on how memory bandwidth intensive your workload is compared to GeekBench.

Edit: if anyone wants to buy my factory 4x8GB RAM, I posted something in the FS section.

Likewise, I got the UltraStudio HD Mini (hanging off the thru port of an OWC Thunderbolt 3 Dock). I wanted the spare PCIe slot, and also the ability to maybe run a Video Satellite from another (sans slots) machine at some point in the future. And somehow I've managed to fill up all the other slots anyway!
