I never know how to spec workstations. Is this an area of expertise for you? How do you know when the graphics card has run out of RAM? I know 16GB is listed by Autodesk as as the minimum required RAM for complex assemblies. We currently use Nvidia K2000 cards and they only have 2GB RAM, but it starts getting very expensive to buy anything better.
Of course, my users all say their workstations are great when I first get them, but after a year or so they are bitching and whining about needing something more powerful. Generally I find that users adjust their workflow according to the spec of their machine, so the more power you give them, the more they will consume. After all, I believe Toy Story was created on a workstation less powerful than the ones we use and Toy Story is way better than anything my users have ever produced!
I'm wondering if cloud rendering is the way to go though?
I'm finding more and more people will load up a system with RAM but not get an equivalent processor. Having 16GB of RAM and a GPU with 2GB of RAM (assuming DDR5 but not sure what that card has) is important, but if you have an i3 or low-to-mid-range i5, that will be your bottleneck. Chances are your disk won't be your bottleneck, but there is always that as a possibility too.

Toy Story was "created" on a workstation long ago. But it was rendered on a massive computational cluster. I have friends who run those systems for movies on par with that and those are hundreds of millions of dollars in high end HPCs that each node has way more power than your workstations.
The difference is that you both create and render on a single device. So the workstation power that you need is higher, but only a little because you are rendering only one thing and only for one person. Toy Story had to render at crazy quality, millions of scenes, many times.
It's still pretty remarkable that they made Toy Story back in the 90s, considering the technology of the time.

Not likely for CAD. Requires a lot of bandwidth and CAD doesn't actually render all that much
Not for CAD per se, we render for our sales brochures and technical manuals. So the graphics guys will take the drawings from the design department and, well, sexy them up I guess. This can take several hours of processing. I don't generally get involved, so I'm not really sure exactly what we do. I'm pretty sure what we do is overkill, but that's just another bugbear of mine!

I don't think that you'll find any functioning CAD shop running anything less than an i7. It is normal to run Xeons.

Oh ok, that makes way more sense. Maybe, but it normally takes longer than that to get into a cloud processing queue. So if the goal is to not deal with the hardware, maybe. If the goal is speed, not likely.

We have ~8 CAD machines. I was rooting for Xeons but got shot down due to price (it wasn't that much more but a $3000 machine is already a bit much). i7s did fit the bill though. We did try some i5s but I got nothing but complaints from the two users we had one them about the speed of renderings and of their program.

The performance difference between the i5 and i7 is much more remarkable than most people realize.

I've worked relatively recently on CAD-like machines (doing CUDA work rather than graphical) and our standard was dual Xeons. They were pretty nice

Generation also matters a lot. Biggest hard difference between them is that the i7 always has more cache. If you are hitting the cache, that is huge. If your workload does not, it's negligable. Outside of that, i7 and i5 share the same cores. Check the clock speed, core count and HT options and likely if they match, they will roughly match outside of the cache difference.

One of my engineers would have loved to work on a dual Xeon box (who wouldn't). He is constantly running into a bottleneck when it comes to doing some of his bigger projects. Thankfully he is really the only one that has that many parts on a single project as no one else is seeing the same slowdowns. He is also running on a 2nd gen i7 which may be part of the issue.

Generation is really a big factor.

Yup, I agree.

Fourth gens have been performing well from what I hear. My i7 in my laptop is 3rd gen.

I've still got a first Gen i7 in my primary gaming desktop. Wish I had the money to update.

You'd probably need a new motherboard too, no?

Probably would need to build anew. Hence the not enough money part. I do have dual 6950s (with the 6970 firmware unlocked) so I could probably still use those.

I would imagine.

Gen 1 i7 on my wife's graphic design PC...triple channel memory....lasted 6 years before the mobo died. I wept a little...lol!

The original i series had a lot of overheating issues. The second gen was much more stable, and they've gotten better and better with each new gen.

@thanksaj now that's interesting. Occasionally the PC would reboot usually overnight and be sitting on the Asus boot screen claiming to have gotten hot or something like that. I never wrote it down because my wife would just start the PC and start working.
