RTX 2080 or two 1080ti? + i9? Any problems with the RTX cards and Rhino?

I’ve been reading some posts that the rtx2080 is not recommended and it’s better to get a used 1080ti instead. My intention is to run rhino 6 and vray or keyshot for rendering on a +30” monitor. What card or cards should I go for for best bang for the buck ? And cpu I’m guessing the i9 9900k is ok? Budget is around $3000usd for a desktop. I can get two 1080ti’s for the price of one 2080… p

… my laptop is starting to create problems like disappearing text in rhino and I can’t have that at work. Need to get a new system ASAP. Thank you.

For VRAY have you seen this blog post? https://www.chaosgroup.com/blog/profiling-the-nvidia-rtx-cards.

AFAIK Keyshot doesn’t do GPU rendering.

Cycles in Rhino works with RTX cards. Can’t comment on relative performance as I don’t have a 1080.

2080 RTX generally seems to match 1080ti but has the potential to go further. For me, the newer card was a no brainer as I tend to keep my hardware a long time and when I bought there was little price difference. But if you can get the older card significantly cheaper then you may consider the saving worth it.


Thanks Jeremy. So a 2080 is ok for vray, but what about Rhino? I read some posts of people complaining that the RTX cards don’t give YET with Rhino 6. Maybe that’s old news and Rhino has been updated to play nice with the new RTX cards. Sorry im not very tech savvy when it comes to hardware. Just want to build a solid machine for Rhino and rendering.

Now here’s the thing: for the price of one RTX 2080, I can get two used 1080ti… What would you go for?

Hi Peter,

I use a 2080 RTX with Rhino (now in a dual card setup with a P4000 driving the screen and the RTX for rendering, but I have used the RTX on its own) and it seems fine.

If I had to make your choice, first thing I’d want to know is whether the 1080’s have been running 24/7 mining bitcoin. Personally I’d steer clear of anything I couldn’t be sure of, but if I was happy with the source then I’d go for the 1080 tis, accepting that I would probably replace them sooner. We don’t know when the 2080’s ray tracing feature will benefit rendering - it may be that when it is, we’ll have third gen 20 series cards with even better price performance.

(If I was into gaming though, then I’d probably go for the 2080.)

The RTX is supported. It can be used with Raytraced just fine.

The realtime raytracing technology provided by the cards isn’t used though (specifically the hw accelleration structures).

But the cards do work.

Thanks. I placed an order for a build with a 2080ti. Here are the parts: https://ca.pcpartpicker.com/list/cGZWxG

I’m hoping this is a good build for my purposes of rhino 6 and rendering vray or keyshot.

hi Jeremy, are you still happy with your RTX 2080 ? looking to upgrade my old GTX 970… if happy is there a brand that you would recommend to purchase or are they all much the same ? many thanks

Hi @rfollett,

Yes, I’m happy with the RTX2080. I haven’t noticed any issues with Rhino in my mixed card setup (see earlier post). I bought directly from Nvidia on the basis that were there to be any problems with a new design of card, driver updates would be most likely to work with their “reference” model. I wasn’t concerned with marginal gains from a competitor.

Bear in mind that there is an updated version out now: check out online reviews.


just to note regarding Keyshot, V9 [coming out soon] is said to support the RTX GPU rendering. https://blog.keyshot.com/keyshot-support-nvidia-rtx-ray-tracing-ai-denoising

[Not that I have that fancy card to enjoy this new version…]


be aware though that RTX cards from competitors seem to have better cooling and run quieter. (saw this in a dutch review of the cards on hardware.info)

the RTX 2080 Super ?

thank you for the update… cheers

As will Raytraced and Rhino Render (both powered by the Cycles engine) in V7 eventually.

I got the rtx2080ti and am quite happy with it. My bank account doesn’t return my texts anymore however :stuck_out_tongue: but it’s nice to be able to render a scene relatively quickly in rhino using raytrace. Still hoping to learn how to optimize the mysterious cycles settings (“integrator settings” “seed”, “ray bounces”, etc) to get a nice quality to speed ratio.

Sounds like a great topic for a new thread, go for it!

Good idea! Will do

will the RTX 2080 super run ok on my current hardware?

looks like i might have to upgrade to win 10 before I spend £700 on a new card - anyone running win 8.1 and new RTX cards? this is a minefield!

In case that you need an affordable Windows 10, here is a place to order one.
I just bought two genuine Windows 10 Pro keys for 16,5 Euros total to upgrade from my Windows 7 Pro. With this code “MgHicom25” you get an extra 25% discount. :slight_smile: Keep in mind that the keys are registered through Microsoft’s servers and “locked” to the hardware ID of your motherboard, so if you change the latter in the future, the license will no longer work on the new machine.
Also, note that if your current Windows 8.1 is Home, it will upgrade to Windows 10 Home. If you have Windows 8.1 Pro, it will upgrade to Windows 10 Pro. You get the point. :slight_smile: However, if you make a clean installation on a formatted or brand new SSD or HDD, you can download Windows 10 Pro and then use the license key to activate it via Internet connection to Microsoft’s servers.

You cannot buy a legit Windows 10 for $15, get serious. It might work, for a while, but it’s obviously not legit.
