    What's your render rig?

    Jeffrey Model

      Lots of discussion about builds and GPUs lately. Figured I'd start a dedicated thread for folks to talk about and show what they're running Visualize on.

          My current rig:

          Case: Corsair 500D

          CPU: i7-7820X

          CPU cooler: Corsair H110i

          Motherboard: ASUS PRIME x299 Deluxe

          RAM: 128GB (8x16) Corsair Vengeance LPX

          GPU1: Nvidia Titan Xp

            Looks like a fun thread Jeffrey!  It'll be interesting to see what hardware others are using. I just finished this new build about a week ago, so perfect timing !


            I'd also really like to see a new standard Visualize Benchmark that we could compare with our various builds. There are so many strategies on what is the best hardware (CPU's & GPU's) it'd be great to see benchmarks versus hardware for some real world comparisons. There are a lot of super talented users on this forum and a little sharing of knowledge can go a long way to getting the most bang for the buck when building a new workstation.


            My new Workstation:

            Case - Cooler Master COSMOS II 25th Anniversary Edition

                      This is pretty sweet ... perhaps within my reach. How do you like the ThreadRipper 1920? And, this is a system I could build into, right ... I mean start with one Titan Xp and add the next over time - that is as long as they are to be found?

                          I think my choice of going with the Ryzen Threadripper 1920x was a very good one. With twelve cores, the Adobe and other software I run that can use the cores really rips! (pardon the pun)


                          This build blows away my prior Intel based rig by a long shot. It should, it has way better specs. I don't have any problems what so ever with any of my software running an AMD CPU. In the past it may have mattered with some software, but I don't think AMD or Intel CPU software compatibility has any issues anymore. AMD or NVIDIA for GPU processing does still matter with some software like Visualize.

                              You did right Mark. You pick your hardware based on your usage. That's the beauty of building your own rig. I did the same but it seems like I went a little overboard (as I usually do). But I won't be upgrading for a long time !  


                              My decision to go with dual Xeons was really dictated by the fact I wanted to use 4 dual wide GPUs. So my motherboard has 7 PCIe slots. At that point you have very slim pickings and really need a server/workstation class motherboard.

                              I originally built mine with 2 1080 TI's but those empty PCIe slots looked so lonely I plugged in 2 more...

                                  Thanks Dave. The AsRock Taichi X399 mother board can accept 4 dual width GPUs.

                                  I know what you mean. The two empty PCIe slots look like barren unwatered soil. I need to plant them with tasty GPUs and make them bear fruit!   If I can get enough freelance rendering work I do plan on upgrading the power supply and installing two more Titan Xp cards.


                                  I'll have to find out how to convert the NVIDIA version cards I have to liquid cooled though. I've been thinking about converting the two I have now to liquid cooled if I can find the info on how to do it for my specific cards.

                                      Watercooling is super easy. Happy to help walk you through it when you're ready to make the leap. My twin Titan Xp machine uses watercooling on the GPUs and the CPU, as does the new quad 2080 Ti rig.


                                      Once you've watercooled one of these GPUs, you'll never go back to air.  Even if there were no performance gains, it would be worth it just for the silence.

                                          My GPUs are actual NVIDIA cards, not EVGA or another licensed brand. I haven't been able to find a kit for my cards, but, I've never liquid cooled GPUs before, and don't know if I actually know what to look for. I thought there would be card specific kits because the chassis is different for the different brand GPU cards.

                                              My Titans are Nvidia reference GPUs as well. In terms of physical layout, the Titan Xp is identical to the 1080 Ti but with one more RAM module populated where the 1080 Ti has a blank space. This means that anything which fits a 1080 Ti will also fit a Titan Xp.


                                              On my Titan rig, I found that the easiest way to get going for water cooling them was to buy a FluidGaming kit from EK. It included everything but the coolant. The caveat here is that these kits use aluminum radiators and therefore aren’t compatible with the much easier to find copper components (connectors, valves, radiators, etc). If you’re not intending to upgrade, these kits are great. If you want something modular which you’ll be expanding in the future, then something copper would work better. I did copper on my big rig.


                                              If it would be useful, I can send you a PM with a BOM for a couple of setups.

                                            Ahhh...   I see.  Just had a look at your MB on Newegg. Very nice, 4 PCI slots but double spaced. That would have worked for me also. I've been tempted to go with Threadripper also. I'm sure the performance of one would be higher than the dual Xeons I ended up with. Less cores but much higher clocks. Much less expensive also....

                                                Also be sure to check that the case you're using can fit 4 double spaced cards. On my Titan build, the Corsair 500D only has 7 PCI knockouts. Thus, the case can fit only 3 double spaced cards plus one single.

                                                  Yeah, but can't you stick seven GPU cards in your rig?

                                                      With a PCI extension, I could fit one more in the big rig. The 2080 Ti has a 2-slot faceplate because of the extra connector they added. The Titan Xp has a 2-slot faceplate but there’s nothing in the second slot, so you could theoretically do them on one slot spacing if you watercool them since that cuts them down to only one slot wide.


                                                      At some point, you start bumping into limits on the number of available PCI-E lanes. With an i9, you get 44 lanes. Set 4 aside from an M.2 and that leaves you 40. The top end Nvidia cards (ie Titan Xp) don’t like having less than 8 even though the bus sits idle almost always. So that means you could do up to 5 GPUs on an i9 box if you had enough physical slots available and a big enough case.


                                                      With a Threadripper 1950X, you get 64 PCI-E lanes (but only 4 memory channels, so you’ll be limited to 64GB). 4 go to the chipset, assume 4 more for the M.2 drive, and that leaves 56. So, with Threadripper you could do a 7 GPU rig.

                                                        Dave Goetsch

                                                        I could do 7 GPUs if they are single slot GPUs or water cooled double slot cards. But as Jeffery mentioned the 1080 TIs have a 2-slot wide faceplate to accommodate the DVI connector, which I don't actually need. I've actually thought about removing the DVI port from the cards but that could be a can of worms. My case is HUGE and has 10 (single) PCIe openings on the rear. My CPU's have 40 PCIe lanes each so I have 80 total. No restriction here. But each EVGA 1080 Ti I have can draw up to 330w. I don't think my 1600w PSU could deliver enough to feed them along with everything else. The AC power cord to my PSU is MASSIVE and could easily be used to jump start a locomotive. For cable management it's like trying to stuff a very pissed off Anaconda behind your desk. Plus, as it is, every time I turn on my computer it dims all the street lights down my street.  


                                                        On another note. I use a EKWB Terminal to tie my 4 GPUs together which I found is really nice as it simplifies your water connections and greatly reduces the number of fittings you need (fittings can be a little expensive). Also, it turns your GPUs into one integrated structural unit that is super stable. Water blocks usually have a large chunk of copper plate that actually makes them heavier than their air-cooled counterpart. Your GPUs can sag from weight and put stress on your PCIe slots. Not so when you use a Terminal to connect all your cards together. No sag at all. It ties your cards together with 12 allen bolts making it one structurally integrated unit.


                                                        I use this one which is a X4 (for 4 GPUs) ...

                                                        But, they also have a X7 version for tieing 7 GPUs together...

                                                            Those terminal blocks are nice. They go a long way towards cleaning up routing and, like you said, the number of fittings.


                                                            I have my big rig set up with two fully modular loops that each have 2 GPUs. My thinking was that this will allow for the easiest upgrade path as I'll be able to just swap cards in and out on a whim. An issue I ran into with this concept was that the fittings are large enough to make tube routing a bit of a pain without a nice terminal block. I went with Alphacool GPU blocks, and it turns out that the Alphacool terminal blocks (SLI blocks) are too large for this usage both because two blocks can't fit side by side, but also because the fittings stick off of the sides rather than the top.


                                                            So, I designed my own bridge blocks. And rendered them in Visualize, naturally.

I appreciate that I don't have to polish them myself, but I'm not sure about how compatible the clearcoat is with the coolant. I may request no clear coat on the next set.

I worked on many military and commercial aircraft including the Space Shuttle for North American Rockwell in Downey, CA. That is not is simple part to produce. Not super hard but not easy either. From the picture it looks like they did quite well. The clear coat was used to eliminate the machine marks (which is why I thought it may have been 3D-Printed) and bring back the transparency. You may be right though about compatibility with your coolant, especially heated coolant.


                                                                          Best of luck, and it looks like you're on the right path.

This ended up at 4 setups on a 3-axis plus a bunch of contouring on the final setup. Could have knocked it down to 3 setups, but wanted symmetry in one feature "just in case."


                                                                              The shop did quite well, but there was a file error which put a half-inch notch straight through a critical area. They're making a new set now without that notch, plus a few dimensional tweaks from my test fits.

                                                        First of all, my excuse for the spaghetti tubing: it is set up so that any component section can be hot-swapped to create a functional loop no matter which single failure happens. It isn't quite as clean as it could be, but the extra tubing lengths are required to support that without kinking.

                                                        Just put together a new rig. The cooling and wiring need to be cleaned up and I need a new circuit run to handle the full power, but I just did a quick test to see how it runs. Using the reference model (Bunkspeed sign) at 3840x2160 and 500 passes in GPU-only mode, I get:

                                                        No denoiser: 1:06

                                                        W/ denoiser: 1:06 (same)


                                                        This is almost exactly double the speed of my other rig with twin Titan Xps in it (also water-cooled). That's pretty much what I'd expect given that the new Turing functions aren't being utilized in Visualize (yet).


                                                        Details on the new rig incl pics and proper performance specs to follow once the new circuit has been run. In the mean time, it's an i9 with quad 2080Tis and water cooling.

                                                          Found a new use for my rig....


                                                          1. Turn radiator fans on low.

                                                          2. Start a heavy render and set time for 15-20 minutes.

                                                          3. Place lunch on rig above radiator vents.

                                                          4. Wait for render to complete.


                                                          Take lunch break and Enjoy !  It really works great !

                                                            I am looking to create a "budget" Boost farm with 5x Dell 5810 Precision Towers and a single GeForce RTX 2070 card in each one. Would I be better off with one computer with a single Titan RTX ($2500) or 5x Towers each with a $500 RTX 2070?


                                                            Running 2018 Sp3.


                                                            5x RTX 2070 @2304 Cuda cores = 11,520

                                                            1x Titan RTX = 4608 Cuda cores

                                                                        5 x 2070 = 2500$ = 11520 CUDA cores (you can actually fit 4 GPUs in one PC)

                                                                        2 x 2080Ti = 2400$ = 8704 CUDA cores

                                                                        4 x 2080 = 2800$ = 11776 CUDA cores


                                                                        Not factoring electricity costs which should be higher for 4x and 5x GPU configurations.


                                                                        Your best price/performance option should be - 1 single PC with 1 CPU and 4 GPUs:


                                                                        • Intel Extreme edition CPUs or AMD Threadripper with 64 PCIe Lanes (2950x)

                                                                        • 4 x 2080 or 4 x 2070 since 4 GPUs can be stacked in one PC and supported by one CPU on x16 speed if motherboard supports it (4 x PCIe 3.0 x16 GPU = 64 PCIe Lanes). If GPUs are on x8 speed, they perform ~3% slower according to most tests.


                                                                        Also You can go with two PCs with two or three GPUs per PC. In all these calculations factor the cost of CPUs, RAM, Motherboard which is at least additional 500$.


                                                                        Considering licenses, with every purchase of SolidWorks Visualize Professional You get Visualize Boost license, but You will loose it if You are not on subscription contract. Cost of one Visualize Boost license is around probably around 1k euro/usd, maybe even cheaper.

                                                                        • Re: What's your render rig?

                                                                              I am currently running a turntable animation that is 10 seconds long at 60fps = 600 images to render. It will take 63 hours to complete on my current 5 laptop Boost farm. My goal is to cut this by at least 60% with the desktops and decent GPU's.

                                                                        • Re: What's your render rig?

                                                                            Jeffrey Model

                                                                            I think the first consideration should be whether your uses need more than 11GB of VRAM. If the answer is yes, then the Titan RTX is essentially your only option (until your apps support VRAM pooling via NVLink).


                                                                            If the answer is no, then I would ask whether five standalone machines are required or if you simply need more GPUs. Figure that each standalone machine comes with about $1500 in cost overhead due to component duplication (PSU, motherboard, RAM, screen, etc). For five machines with 2070s inside, you're looking at around a $10k spend.


                                                                            If you do not need 5 individual machines, then you'll be best served by putting four GPUs into one machine. For the same $10k budget, you could put four 2080 Tis into one machine and water cool the whole thing. You'll end up at around 3x the performance of five machines with 2070s, not including the even larger improvement on shorter renders since you won't have to wait for data to be passed around the Boost farm.


                                                                            If you're simply looking to beat the performance of 5 laptops, just put two 2080s or 2080 Tis into a desktop. Laptop GPUs are significantly slower at sustained renders even when they have GPUs with the same branding as desktop ones.

I was favoring a ThreadRipper build, but I sure as hell wasn't planning on three GPUs out of the starting block - so, I would see even worse performance?! Jeez!

                                                                                    Justin Dailey

                                                                                    TR build will still give you the best possible performance per dollar vs anything intel.  I'm not sure how it compares to other AMD offerings atm.  My render rig is also my gaming pc and I have a separate SW workstation with 7700k @ 5GHz and a P4000 so TR made sense in my scenario.  I already had the two 1080FE's and I bought the 2080ti as an upgrade for gaming but since visualize can still use the cuda cores, I left the 1080's installed.  CPU should be fine to render still images.  The added GPU speed is nice for 2000+ frame animations (if they don't slow down or fail). 


                                                                                    After spending this entire week trying to get my project to render..  I'm concluding that the "slowness" is due to terrible vram management & file efficiency by visualize.  My project is 2.5M polygons but it takes 10 mins to open the project and 15-20 mins for an animation render to start.  Luckily it fails in the first few frames but it still takes me another 30 mins to start another render just to see if it fails again.  Now I got it to not fail on "fast" setting and it starts off fast (1000 passes/frame in under 10 secs) and then slows way down (1000 passes/frame in 1.5-2 mins). CPU & GPU usage drops to almost nothing.  Temps are fine; vram usage is less than 75%; ram usage is at 26%; there's virtually zero disk usage; I cleaned the temp directory; no other programs are running; I updated to 2019 SP1; I tried redoing the entire animation in 2018.  I have no idea why it does this..  All I know is that it shouldn't and I'm very angry because it has wasted so much of my time.

The stock air coolers on the Nvidia cards are pretty bad when they're in open air, but your setup has them completely choked off from any cooling.


                                                                                    The other thing is that, yes, Visualize is very unstable on the 20-series cards.

                                                                                    Im using a GTX 780TI for SWV 2019 renders. GTX780TI = 2880 cuda @ 875Mhz.

                                                                                    With new PC, if i jump to 4 x 2080 = 11776 CUDA cores @ 1350Mhz, can i get x4 faster or more due to speed clock increase?


                                                                                    Thanks in advance,

                                                                                        Jeffrey Model

                                                                                        It should be even more than 4x the speed because of two reasons:

                                                                                        1. The higher clock speeds. The boost clock on the 2080 is approximately double the speed of the boost clock on the 780 Ti (1800 Mhz vs 978 Mhz)
                                                                                        2. The 780Ti only has 3GB of VRAM. This means that it cannot be used with the denoiser feature. The denoiser alone can give a 10x boost in performance by requiring fewer passes in order to get the same quality. The 2080 has 8GB of VRAM and is compatible with the denoiser.


                                                                                        One simple test is to perform the test render according to the settings here and see what you get. Expect the offline render at 3840x2160 and 500 passes to take approx 1:30 on a set of quad 2080s.
