What type of machine do you work on?

Recommended Posts

A little update on the iMac versus a Mac Pro. I made a little 9 minute photo slideshow thing for a friend, nothing crazy, just scales, rotations, all that and some music. It took about 15-16 minutes to render at the office on my late 2008 Mac Pro 8 core with 18 gb RAM and multiprocessing using 6 cores. I had to re-render it here at home on my iMac i7 4 core with 2 gb RAM and it took about 9 minutes with multiprocessing turned on and using 3 cores. The only difference between the two machines is the iMac has Snow Leopard and the Mac Pro has Leopard, so maybe there's something under the hood (like Grand Central, maybe?) that make rendering more efficient. I check Activity Monitor at work and home, and it seems the iMac using the 3 cores much more efficiently than the Mac Pro, with all 3 cores working at around 200% with spikes above that. The Mac Pro usually hovers around 100%, but has spikes here and there.

 

Obviously with the RAM difference I can multitask on the Mac Pro better, any time I opened another app on the iMac the activity on the render dropped dramatically, but with only 4 GB RAM, that's to be expected since there was almost nothing left during rendering, around 28 MB free. I'm curious to do more tests, maybe it's time to upgrade to Snow Leopard on the Mac Pro. Anyone else notice any real-world performance gains?

That's odd that there is that much of a gain, given the operating systems of both machines were still only running a 32bit version of AE. Is it just the fact that snow leopard is doing a better job of dividing the workload? with the additional cores and that much more ram, it seems like it would off set the faster OS.

Oh , another thing really easy getting used to on a MAC is that you'll forget the world of Viruses, Spyware, Adware, Annoying "Click Cancel to install this trojan.exe file" Messages and so on.

 

And ye , parallax, calling someone's opinion bullshit is your style? Thought you had more in ya.

All I can say to that is weird shit happens when you have MP enabled in AE. Usually for me, it just makes things unstable. You can't expect 8 cores to do much for a program that has MP built in as a half-assed afterthought.

 

But let me tell you how I really feel... :)

Haha, I go back and forth on it myself. Some days it's fine, some days, like yesterday, I turn it off and get pissed about having a whole lotta computer that AE can't use. One can only hope that it gets better in CS5, but that's probably just wishful thinking.

Sounds like you haven't used a PC in a couple years. It's probably been ten years since I've even seen a virus, and I haven't had a single piece of spyware or adware on any of my computers since Vista was released. If your computer is getting infested, you're doing something horribly, horribly wrong.

 

In terms of stability and power, Windows 7 and OSX are pretty much on par. There's no huge upside or downside to either. The age of "Windows always crashes" and "OSX is stable and secure" is over. Like I said before: it's just a matter of preference now.

I've got super duper high hopes for CS5. Real 64 bit (unlike CS4, which is only 64 bit in the marketing materials) should eliminate about 90% of the crashes I get due to memory errors. Hoping it's got good MP support too, but the memory usage should be a huge performance enhancer.

 

Like motion graphics viagra.

For all you guys having trouble with MP rendering - I've started background rendering in terminal for most of my big projects. So I'll just open 3 or 4 aerender instances depending on how heavy the render is. MP without the hassle of doing it in AE. I find it to be much fast and much more stable.

I've been using bg render over regular render for months now.. I've been too lazy to figure out if there's a faster in program setting for rendering but it always does the trick.
