AE CS4 64bit

[Kevin Camp]

nope, it is still 32-bit, but (like cs3) it will access more than 4gb of ram if you have a 64-bit os, multiple processors/cores and enable multiprocessing (render multiple frames simultaneously). then it can use 2gb per processor/core.

Thanks Kev!

Hey Kevin, with the intro of the new core i7 processors, and the reintroduction of hyper-threading effectively, will After Effects see 8 cores instead of 4? And if it can utilize 2 gigs per core, is 16 gigs of ram necessary for maximum performance? Thanks!

[Zach Meissner] “with the intro of the new core i7 processors, and the reintroduction of hyper-threading effectively, will After Effects see 8 cores instead of 4?”

i don’t know for sure, but i think it would… i know the older intel cpus that had hyper-threading appeared to the system to have 2x the cpus. i assume the same will happen with i7… if the system sees 2x the cores, the ae should too.

[Zach Meissner] “And if it can utilize 2 gigs per core, is 16 gigs of ram necessary for maximum performance?”

i would assume, that if the ae sees the for i7 cores as 8 cores with hyper-threading), then it will launch 8 render engines. each of those render engines should be able to grab 2gb of ram… unless hyper-threading requires that a single core must share the same ram block (kind of like multiple gpus in sli have to load the same data in vram on each card so 2 512mb cards in sli effectively have 512mb of vram, not 1gb). i haven’t heard of anything like that, but i haven’t seen any testing with the i7s and ae, yet.

i’m pretty interested in seeing what the i7s will do for ae, but as with most early technologies, i won’t be the first to buy it, but i can’t wait to read more about it….

I just built a I7 overclocked to 3.8G,12 gigs, Quadro CX card on a EVGA board. I just installed CS4, and I’ll let you know what happens when I fire AE up and dive into the settings to test it.

That’s a beast! Cant wait to hear your report, thanks Chris!

[Chris Hayward]

the verdict:

AE CS4 registers the I7 chip with 4 processor cores, and the hightest it reads is 2.8GB per CPU for me.

so,

so far, I like it 🙂

[Zach Meissner]

Thanks a lot for filling us in with that great info!

I had a few more system specific questions Chris, i would love to talk shop if you have a few free moments. My email is zach@lab316.com

Thanks Chris!!

I just built an intel i7 930 setup with 12GB ram.
My results with CS4 as far far from positive.

Rendering at 1080pand using windows task manager Im getting 17% CPU usage in total with only 4 of the eight cpus working at less than 50% each.

So my computer is no faster than my 3 year old machine!

boooo

Wait until CS5 and pray they get it right this time!

[Remy Mainz]

Ok , if thats so where is my bottleneck?
I know its not my RAM or Raid or x58 mb.

My CPU is only running at 17% and is still taking me 8 hours to render 15 minutes. The same as my old q6600 pc.

Something is holding AE back from using the other 83% of the processor and Id love to know what it is. When I render in 3ds max 2009 it uses all 8 cores at 100% all the time. I can understand CS4 not using hyperthreading or all eight cores but its not even using a single core at 100%.

If I knew then maybe I could relax and know I didnt waste all that money.

thanks
