Octane X on iMac / which eGPU?

[atoyuser1]

Hello Lovely People,

Got some numbers (and a set-up) that might be of interest to some people here.

I am running a MBP 16" Intel 2.4 GHz 8-Core Intel Core i9, with 64GB and a 5500M inside it.

Attached I also have 2 x Razer Core X boxes. One has a 5700XT and the other has a 6900XT (both are Gigabyte cards).

I've only run the Chess Scene and the results are:

5500M = 46 seconds
5500M + 5700XT = 15 seconds
5500M + 5700XT + 6900XT = 7 seconds

Depending of what news comes of Octane 2022, I might continue with the next bit of my build.
I have a Mac Pro 5,1 at my feet, that I'm thinking of loading the 5700XT into with a second 5700XT as a node and buy a second 6900XT to replace it in the Razer Core X.

Wonder what speed increases I'd see?

Thanks, any questions I'm happy to answer

Hi snahbah.

How did you get the 6900XT in the razer core X? It wouldn't work for me due to lack of Power slots:

Sorry to highjack this thread.. I have an Razer Chroma X and a GTX 3090. Will that work on a MacBook Pro M1 in Octane? And can I use them both at the same time in Octane X?

You cannot use external GPUs at all with M1. I found this out the hard way

That's very bad news..

Redshift on M1 is getting 3090 speeds, but even so fees like no point in going Mac till at least the next cycle
