In the third part on Revit + Hardware turns this time everything about processors, memory and operating system.
these three issues I have summarized aware as they are always interdependent.
Let's start today with the simplest of those issues, the operating system.
Before I here a recommendation nor a notice in advance. My recommendations are in the first line of the new acquisition. Existing systems you should only examine their suitability towards. The minimum requirements are specified explicitly on the Autodesk site. Each Revit system should then be run be. The aim of my recommendation, it is a system described by which it is also fun, and with which one can work smoothly.
very important at this point, this is a recommendation for Revit Structure. The requirements for Revit Architecture particularly in the rendering area are now several times higher. Anyone looking for it should, nevertheless share with its Reseller of trust precisely apart.
The requirements necessary to Revit just from memory are far greater than in AutoCAD. For 32bit systems, there are already enough tips by Autodesk, the RAM with the 3GB switch to increase. But this is only a stopgap measure. Who should now puts together a new machine is usually equal to a 64bit system. For a 64bit system like Windows 7, the restrictions accounted for the main memory. Here one is held back only by the processor. Who wants to work properly with Revit, comes to this configuration is a must. I've been working a while with WIN 7 Pro, and have no driver problems. The BS operates a total of defect-free (fewer crashes) and liquid.
Now the only question about the amount of memory to be clarified. This is closely linked to the processor. For a selection in the processors we have the i5 Core, Core i7 and Xeon processors.
The Core i5 and i7 boards are placement usually with 4 memory banks, in the dual-core Xeons already 18 at This is so up in the Core i5 and i7. 4x4 = 16 GB Ram possible. Drawback here is that the 4 GB bars are almost twice as expensive as 2 GB. As a CAD workstation, but still reasonably should be affordable, I've decided to 8GB. So far I was able to work under normal Revit (no rendering), found no adverse effects.
8GB RAM should be sufficient for the normal functioning in Revit. This one should work through common projects of ordinary size can. Increasing the project size and hence the file size, or are working with other designers (architects), in a joint Projketdatei are other considerations necessary.
all we have is still the choice of the appropriate processor. The following pictures illustrate the differences between a core i5 760 (2.80 GHz), and a Core i7 870 (2.93 GHz).
Core i7, rendering with shadows, printer 300DPI
Core i7, rendering with transparent components, printer 300DPI
Core i7, rendering the reinforcement, printer 300DPI
Core i5, rendering the reinforcement, printer 300DPI
Core i5, rendering aborted show
The images here clearly the differences. But it is worth it clear once again working with Revit is a Core i5 very possible as long as you render only occasionally used. The added cost of a little over 100 € for the Core i7 870 is certainly a good investment. This is ultimately my recommendation. Who needs more RAM, and a lot Renders should be but rather look for a Xeon processor.
