Hello there, long time lurker, first time poster here. It feels a bit cheeky to kick off with a question (especially a long winded one, sorry) but I'm keen to clear a few things up before the, hopefully, imminent mac pro refresh. I know that once they are announced I'm going to have a very itchy trigger finger. I'm about to make a career change and move into 3D visualization / CGI while continuing with a certain amount of 2D artwork for print. I use Cinema 4D, Photoshop, Illustrator, some Final Cut and Motion and I can see After Effects being added to that list at some point. Until now my trusty Mac Book Pro (2.33 Core 2 Duo 3Gb RAM) has served me well until it comes to rendering or dynamic simulation in Cinema, or rendering in Motion or FInal Cut. My eye has been on the "Two 2.26GHz Quad-Core Intel Xeon" Mac Pro, I'd bump the RAM to 8Gb to start with. But like many others I've been reluctant to pay what seems like over the odds especially when we want to believe that a new machine is round the corner. Following (somewhat compulsively) the various threads on the new Mac Pros I've come to realise that while more cores will really help rendering in Cinema it may not be so useful for other tasks. For instance a quick test running a dynamic simulation and watching the Activity Monitor shows Cinema only using about 99% of CPU, compared to almost 200% when rendering, so I must assume the simulation is not multi threaded? Equally I've read that many other apps, like Final Cut or Motion, will use at most 4 cores and often just 2? Questions: I believe I am correct in thinking that each core will be seen as 2 cores by the system, so Cinema will have 16 render buckets on the go on an 8 core machine? Considering the kind of work I've described what are people's opinions re the configurations below? Both are around my budget, I'll be getting a new monitor and Apple Care on top. I realise that the configurations will change after the refresh (and the decision to wait or not will be made after WWDC) but this could make the argument all the more valid as it could be 6 fast cores vs 12 slower ones. I also understand that speed isn't only about GHz, although with pure rendering its a pretty good measure. Two 2.26GHz Quad-Core Intel Xeon, 8Gb RAM = £2635 ($3399 on the US store) 36.16GHz assuming 16 logical cores 4.52 GHz when using 2 cores One 2.93GHz Quad-Core Intel Xeon, 8 Gb RAM = £2472 ($3149 on the US store) 23.44GHz assuming 8 logical cores 5.86 GHz when using 2 cores Thanks very much for your help.
