    Default Happy with your Hardware?

    I am upgrading my machine and I don't want minimum specs.
    I am using MEP 2009 and 2010 vertically.
    If there is anyone happy with the computing power they have, can you please let me know what your specs are.
    I am doing research, but I would like some user feedback.

    Does a dual CPU have any advantage?
    Does a solid state hard drive have any advantage?
    2009-->OpenGL, 2010-->DirectX, is there a Excellent choice for a video card?

    Who's machine out there rips?
    Is anyone using a MAC with parallels, bootcamp or crossover?

    I don't work on small projects. The last 3 projects were a 14 floor downtown skyscraper, a 6 floor medical research building and a 11 story courts building. These files get huge and performance really suffers. I need something that rips.

    Heres what you have to do, go to Hill Valley and find a man there named Doctor Emmett Brown. He has a time machine that will take you into the future where you can get a PC with a 16 terahertz 32 core cpu....

    I too would like to know if anyone has found an answer to speed revit up on the hardware side.

    P.S. Don't buy any sports almanacs on your adventure.

    Well, Doctor Emmett Brown says not to bother purchasing his outrageously priced machines. He tells me no matter what I do, nothing will improve the performance of Revit. It's a software issue not a hardware. I kinda figured so, but was optimistic that somebody out there has the magic combination of hardware.

    64-bit dual core 8gb RAM and 750mb or 1.5gb video card would be my recommendation. I do not know all the other specifics you are asking about, sorry. However getting a flux capacitor could also do the trick. =)

    Also use 2010 revit MEP, good performance gains on large projects from 2009.

    Red face Re: Happy with your Hardware?

    Only reason I say that is we moved from 3GB with 32 bit (3GB switch) to 8 GB with 64 bit and the speed of the machine did not drastically improve. So I do not see the need for overloading the RAM. The extra RAM did prevent us from running out of RAM and crashing.

    This was on a project that was about 75MB MEP file and over 500MB in linked models. With all that loaded we still only clocked the RAM usage at 5 GB and that is 3D fine detail/shading w/ edges. 350k sq ft new model and 350k sq ft existing model.

    So based on that experience throwing a lot of RAM at the software will not fix the problem.

    Just my .02.

    jbroker,
    They used to have a benchmarking folder in the revit hardware section, where people ran a program that scored their system to compare to other systems. I wonder why they got rid of it? That would have answered your question right away. From what I remember, a properly spec'd computer had scores that were twice as fast.

    Aside from the amount of ram, how does the speed of ram affect performance? Here at work I would like to try i7, 64 bit, with 8gb of whatever the latest ram is available (1600?) for our next revit station. I have a i7 machine at home and personally think its worth the money ($1K for a system).

    Clock speed and ram are key. We have some workstations with 3.16 GHz Core 2 Duo, XP32, 4GB ram, and they are faster than the 2.83 Ghz, XP64, 8GB ram machines we have. However when we Frankensteined the 3.16Ghz with XP64 and 8GB it blew away either machine in the benchmark.

    Other System Info: 10k RPM SATA drives, all web updates, latest quadro drivers, Dual 19" LCDs, 3GB switch on XP32 machine

    We also tested a Quadro FX1700 vs. a Quadro FX570 in the same machine and the benchmark was identical. Spend money on clock speed and ram, not the vid card.

    We have a Xeon with the Nehalem core (basically an i7) coming next week. I'll try to remember to benchmark and post results.

    Revit needs CPU power. This is by far the most important.
    Intel i7 is currently the fastest CPU. Over clocking the CPU is basically a necessity.
    Big projects need memory and memory is cheap. get 8 or 12GB (use vista x64)
    SSD for the hard drive. Use Intel, G.skill Falcon, or OCZ Vertex.
    As long as shadows are off, the video card is still unimportant, even with 2010's DirectX.

    I would recommend a custom build using an i7 920 with very good aftermarket cooling, 12GB 1333 DDR3, X58 motherboard, G.skill Falcon SSD, and a GTX275. Have the local shop build it and give it a conservative over clock, perhaps 3.5Ghz. If you want the very best, for an extra $1400 go with an i7 975 extreme edition for about 4.2GHz over clock and stripe another SSD in RAID-0.

    Make sure your LAN is 1000Mbit or better back to the server.

    That’s the best you can do right now. Revit will only use up to 4 cores when rendering; when modeling it is single threaded, so you are limited to the single core most of the time. Basically just get a single quad core.

    I was looking for that real world testing and know how. Excelent information. I will go with your recommendations.
