We did some study for the computer spec for REVIT and the results are very interesting. Maybe someone can explain this.~

We compared 2 computers, desktop with Pentium D 2.80 Ghz with 4 GB of Ram and Laptop intel centrino with 2 Gb of Ram. With the same procedures, the laptop can processes almost 40% faster than desktop. After looked at the journal files, we found that the L2cache of the desktop is = 0. Our IT guy checked the desktop and found nothing wrong with the L2cache. Can anyone explain this??

 If you want to see the jounal file, leave the E mail and I can send it to you.

Thanx.

Pentium D is old and out-dated technolgoy. what's the FSB (Front Side Bus) speed. what was the laptop running?

if Intel, your minimum Desktop should Duo Core 2 technology at least

Thank you for your reply. I understand that Pentium D is old and out. But, in my opinion, centrino with less RAM which is even older and not supposed to run faster.

centrino is the moble technolgy . it all depends on what version of centrino you are talking about. this technology is upgrade along with new processor technolgoy. i think the latest version is Intel Centrino Duo which use the latest Intel chips.

The tests were actualy run on two different desktops and the laptop.

The theoretically fastest machine was a desktop with the following processor:

Intel Pentium D 925 Duo Core 3 Ghz, 800 Mhz FSB, 2MB L2 Cache

The Laptop's processor is:

Intel Pentium M 2.26 Ghz, 791 Mhz, 2MB L2 Cache

In looking at the journal files we noted that the laptop journal file indicates the L2 cache properly as 2048 while the Desktop journal file indicates the L2 cache is 0.  Not sure this has anything to do with the performance difference, but it is the only clue we have found to explain the underperformance of the desktops.

no point in buying any new hardware at this time because

revit will soon go 64 bit and only then will you need to

buy new hardware along with Vista64..
