    New workstation, Revit 3D

    Hi all!

    Building my first workstation and I'm not good at that section and could use some help.

    The workstation is strictly only for Revit and specifically being used to render in 3D, not gaming.
    My budget is 15000sek (1750 dollars).

    Kundvagn - 2015-08-11 - Inet.se

    CPU: Checked other sites and most of them prefers i7-5820k over i7-6700k.
    GPU: Is it enough or should I focus more on my graphic card than the CPU?

    What are your opinions on my build? Totalt cost for that is 1780dollars

    Thanks in advance!

    Hello,

    I like to use the 5820k with revit builds but I do recommend you go for a higher end motherboard and power supply. While technically your system under FULL cpu and gpu load will be around 350watts, I would get a gold rated power supply in the 650-750 range as 50% of the power supply output is usually ideal efficiency. I like using the seasonic x750 or the new corsair RMi and RMx series are excellent. Anything from Seasonic is great and they actually make a lot of the rebranded power supplies for other manufacturers.

    If you will not be doing gpu rendering (think you might be though) you can go down to the 2GB gtx950 if it helps get a better motherboard and power supply. Those two items are really the heart of a reliable system.

    Motherboards, I am in love with the asus x99-m ws as matx is enough for most and it gets you the high end build from their WS series. I have had great luck with the Asrock WS series as well.

    Edit:
    I want to add, I may have missed it but I did not see a cpu cooler in your list. the x99 series does not come with a cooler. The coolermaster hyper212evo does great as well as the phanteks ph-tc12dx for non overclocked builds. If overclocking, let me know.

    Revit uses cpu based rendering, so if your using something like lumion or twinmotion, you can go for the 6700k and a gtx 970 for better render times.

    Hope that helps

    Hi again Hafa,

    You're giving up a significant amount of single-threaded performance by going with the 5820K over the 6700K (probably around 15%). The six cores will be nice for revit rendering, but rendering better be a very significant part of your workflow for that to be worth it, in my opinion. For most of what you do in Revit, you are paying more money for less performance. That's not to say the 5820K is a BAD choice - it's still a great CPU. Just my 2 cents.

    I'm not sure I agree with remiscs on the PSU wattage... I think 500W PSU is good enough for that system... you would only need more if you were planning on adding a second video card. He has a great point about the CPU cooler - I'm a big fan of the 212 EVO as well.

    The 250GB SSD is just a little tight long-term, but if 500GB breaks the budget, you can get by with 250GB.

    Good luck!

    I agree regarding the cpu, the 6700k is not only higher clocked but its IPC (instructions per clock) are much better than the haswell counterparts. In my testing the single thread performance between haswell and haswell-e is darn near the same, so the 6700k at 4.2ghz will be faster than the haswell units at 4.4ghz. The 212evo is a good little cooler for sure, I have seen them keep 3930k cool with broken fans lol If I have a complaint is that the fans tend to fail around 2-3years which is good considering the price.

    I will say though, while watching revit in action at my customer (I dont use it), the 4.4ghz 5820k was perceived to be as fast as the stock clocked 5930k in the office, they dont do cpu rendering though (lumion and twinmotion). That said though, unless your doing a lot of rendering with the cpu, the 6700k would perform better day to day. I will say the argument for the 6700k is even stronger if your rendering is gpu based, then there really isnt a need for x99 chipset as the z170 chipset even supports 64GB of ram now too (16GB modules vs 8GB standard modules in x99). The x99 in my area is just literally $20-40 more expensive so most customers rather go with an overclocked 5820k.

    Regarding the psu though WITH ALL DUE RESPECT, in all of my builds the power supply is one of the objects I refuse to skimp on, I also design my workstations to have the highest reliability and lowest downtime. I do not doubt that a 5820k technically will not pull more than 250watts total system (heck they idle at 70-80watts), but with the cpu and gpu both carrying a load total system watts can peak 360watt in that system. I built an overclocked system with a 5820k @ 4.4ghz 1.275v with an evga 980ti that had a peak of 460watt under max load. That is why I think the 500watt is just a bit too low. Not to mention power supplies tend to degrade over time.

    I would not get a bronze psu for a workstation that is used to generate income and the price difference between a 500watt gold and a 650-750watt gold is small enough to justify going with a 650watt psu at least. My logic is that the psu and the motherboard are two of the most time consuming parts to replace, if one fails it will lead to a greater downtime, thats why I dont mess around with power supplies. Also, cheaper power supplies dont have as clean of a volt output which can even lead to intermittent issues as well. Another thing I do in my workstations is to use a modular psu, that way if one does fail, I can replace it in less than 15mins since I dont need to reroute cables.

    Remis, I agree with your recommendations about the PSU, and especially not skimping on a quality high-efficiency PSU. Thank you for sharing your thoughts about it.

    I could have been more clear that I was only suggesting the 500W is "good enough" in the context that Hafa seems to be trying to keep this on a low budget, and I don't think more wattage is justified if that's the case (just my opinion of course)... even at peak usage, his system probably wouldn't hit 300W. I'd rather see the money go into the "quality" side.

    Hi guys,

    Thanks alot for the time and efford you are putting in!

    I'm mostly used to AutoCAD 2D and not that much in 3D-rendering. I have been working lately more and more with revit and CPU-rendering takes forever. While GPU rendering is alot faster, did not know about lumion and will give it a try.

    What are your recommendation GPU or CPU rendering? I prefer great quality and time saving.
    And thanks for pointing out about the cooler and PSU forgot it, added the 212evo and a 80+gold with 650w.

    After considering what you suggested I have these components together, any thoughts?

    i7-6700k, just below my budget 1743 dollars.

    i7-6700k, with a more powerful graphic card. Total cost 1777.

    Yes I am.

    Will try to get it soon now that Black Fridays is closing in.

    I would only go for the 970 if you plan on gpu rendering, did you look into lumion? They have trial periods for you to try their software out, you can import a revit file into it.

    Well if you stick to cpu rendering you will be glad you went with the 5820k but if you switch to gpu rendering the 6700k will be nice.

    Just keep in mind, the 212evo is great but will probably barely be able to overclock the 6700k to maybe 4.3-4.4ghz, the evo does good on a stock 5820k but overclocking may be limited to 3.8ghz, maybe 4.0ghz with a good low volt cpu.

    oh the asus x99-a is nice too, did a 4.5ghz overclock on a 5820k build recently with it and the phanteks ph-tc14pe cooler.

    The msi board you picked is good but more of a budget board with less beefy power delivery for overclocking the 6700k.

    Thanks for the respons.

    The 970 looks alot better. I tried Lumion on a r9 380 and worked great and WAS awesome, thanks for that tip guys.

    So far I have only been doing CPU rendering, takes ages for it. I'm interested in a kind of rendering with great quality and timesaving.
    What do you prefer GPU/CPU?

    I have no plans in the future to overclock the computer.

    MSI board was chosen due to the short budget.
