Revit 2020 - GPU?

[Anonymous]

We have some Revit model ~1GB in size to be exported to .nwc

Our old workstations can't do this task...They can open the model but everything feels so slow.

And Revit 2020 will crash around 1 hr after initiating the export to .nwc.

I understand in the past Revit is mostly relying on CPU rather than GPU, but is the thing changed in Revit 2020?

The specs of the workstations:

CPU: Intel Core i7-7700 Quad-Core

RAM: 32GB DDR4 Non-ECC

GPU: NVIDIA Quadro K1200 4GB

Storage: 500GB 7200rpm SATA 6Gbps HDD

"can't do the task" and "feels so slow" means nothing to anyone here sadly.
Also, where is the model stored and how do you connect to it? How complex is it? What is it?
What else is running on the PC? What is the age of this PC? That is a slow low-end HD choice these days.

Scroll down to the Revit 2020 Value then Performance sections and note the processor requirements as well as GPU etc. for reference

The models are stored locally. Pan, Zoom and Orbit operations etc will see lagging. I guess the GPU is to be blamed there.

I am not doing that job so cannot tell the complexity. It's a number of condominium blocks with models of other systems linked in one. The file size goes up to 1.1GB.

About the link I've read it multiple times, but "Multi-Core Intel Xeon, or i-Series processor or AMD equivalent with SSE2 technology. Highest affordable CPU speed rating recommended." Can Autodesk explicitly tell me at least how many cores and how high the clock of CPU I need? Only the RAM requirement is specific. 

Though I know at least in the past Revit is a CPU-intensive programme, but the requirement for GPU "DirectX 11 capable graphics card with Shader Model 5" is really loose. Obviously in my case it is not fast enough to display the model to screen real time.

Again, can Autodesk give more specific hardware requirements so that users can follow?

P.S. Seems the Navisworks exporter now can work successfully. The usage of RAM peaked at around 28.5/32GB. I was not running other programmes though.

>>>...Can Autodesk explicitly tell me ...<<<
No, they won't do that. And yes, Revit is still CPU intensive.

If you want someone to spec a system for you, contact a system reseller like DELL and others, they will gladly offer up specs for your new PC. Or pay a 'consultant' for the same, lots of folks out there, you might find someone here https://servicesmarketplace.autodesk.com/providers/product/revit

Actually Autodesk can do better - they give more specific requirements for products e.g. InfraWorks, Civil3D, Recap etc...

Without the requirements posed by Autodesk it's hard to convince your boss to procure/upgrade hardware. Shame...

1.1GB? I'd be laying the blame for the lag on the file not the computer. The specs you gave for your workstation seem reasonable, The only potential bottlenecks you have are the HDD and your motherboard. You can upgrade to an SSD pretty cheaply, just takes time to re-install all the software. If you're using a pc from a reputable dealer (dell, hp, etc...) then the motherboard should be fine.

You mentioned that the file contains a number of condominiums and their systems are linked in. I'd be looking at separating the condos into separate files and linking them to a site file. It's a different workflow to what you've been doing buts the best way to resolve this.
