Revit with 64 bits technology

hi,

Who knows something about revit 8 performance with 64 bits AMD processors??


thanks

We are rolling along without any hiccups on 9 machines with AMD Athlon64 4000+ processors and will be getting more soon.

Any comments on performance improvement?

Regarding the 64 bit part, check out this thread (unfortunately it gets way off topic in the middle, but the short answer is that unless you're using over 3GB-4GB ram, 64 bit isn't going to be any better than 32 bit):

If you're wondering, there's no reason not to go with the Athlon64...

Performance increases on 64bit Athlon (or Intel for that matter) won’t be seen until there are 64bit programmes, and Revit Building 8 isn’t 64bit.

You will also need a 64bit operating system. Initially 64bit versions of Windows will be XP Professional & Windows Server 2003 (Tablet PC and Media Centre will follow).

Using Release Candidate 1 of Windows XP Pro 64bit, a recent report in PCW said there was a greater performance increase in tests with Intel PCs over Athlon, as the Windows 64bit operating system makes better use of Intel CPU’s hyperthreading technology.

Of interest to you, PCW said ‘The performance of 32bit programmes does not change appreciably under the 64bit operating system…. tests was almost identical to that on the 32bit platform’

I suppose the only advantage of using 64bit hardware is that the system can address up to 128GB memory, as opposed to the current limit of 4GB with 32bit operating systems. So, if you have large files and 4GB memory isn’t enough then the extra memory you can have with a 64bit machine may give you some benefits, but not in performance terms.

64 bits can in theory address 16 exobytes.

But yes, right now it's like filling your old gas guzzler with premium...

I know this much for sure ever since going to these machines I have yet to lock one up by that I mean the processor staying at 100% for more than a 2-6 seconds max. Hope that helps.

How much RAM do you have in your machines?
Thanks

We have 2 gigs in our machines. I should also note that when it does take the 6 seconds it is on a 4 story over 1 story of parking highly detailed condo building other than that it is smooth sailing.

Great analogy.

However, just a quick note, you might be able to get more 'bang for your buck' with the AMD's. They are fast and capable, and can be cheaper than the Intels. So regardless of you not being able to use the 64-bit portion yet, it might be a better deal anyways. Check out Tom's Hardware or a simluar site for Benchmarks and then look at the prices of said systems and you'll see what I mean.
