Here's a question. Will the 64bit move by Adobe offer anything if it's run on EFI32? Will I notice improvements even on my 2006 1,1?
For standard desktop users it isn't better (at least yet). That's why if you buy a brand-new Mac Pro today with OSX client (not OSX server) it'll boot the 32-bit kernel.Well yeah, that's why the 64 bit kernal stuff is confusing me. What is it exactly about the 64 bit kernal that makes it better?
I was wondering the same thing - more specifically though, will CS5 be able to address more than 4 Gig of memory on my 2006 1,1 MacPro?Here's a question. Will the 64bit move by Adobe offer anything if it's run on EFI32? Will I notice improvements even on my 2006 1,1?
Fixed. When speaking strictly from a RAM perspective...yes.
This. If you have more then 3GB of RAM installed, CS5 should be able to use it (ignoring processes using additional memory).The software can definitely address more than 3 GB of RAM even if the kernel is only 32-bit.
Adding to what you mentioned (well, this is just a very quick overview from Lloyd Chambers) ...Some programs already perform (slightly) better when the 64-bit
kernel is running:
I think it might be worth noting that you get more in 64-bit mode
than just a larger address space. For OS X you get NX stack and
heap protection. There are more registers - that can mean more
efficient code. There is an extended instruction set.
source: http://macperformanceguide.com/SnowLeopard-64bit.htmlTests of photographic applications show that the gains of booting with the 64-bit kernel can be substantial, keeping in mind that a 30% gain via hardware often costs several thousand dollars more. Why not get a good chunk of that for about $25?
Your 64-bit programs (if any) will run fine on a 32-bit kernel, gaining the benefits of 64-bit-ness. But they wont see full performance that way.
You'll be fine. If the application in CS5 is 64-bit, then it will be able to address more RAM then your machine can hold. And it seems like CS5 has to head for 64-bit.So with all due respect to beto2k7 can anyone confirm that this is correct (that CS5 will not be able to address more than 4 GB of RAM on my 2006 1.1 Mac Pro) - because it will be the one and only reason why I would want/need to upgrade.
That's what Adobe claims.CS5 should, finally, be ported to Cocoa 64-bit (from Carbon), so it can access more ram and resources.
Sorry, but there still seems to be some confusion here still. To quote Pressure - "any individual application is still limited to a 4GB limit" but you state that CS5 (I'm assuming you mean the single Photoshop application) will be able to address all my RAM.You'll be fine. If the application in CS5 is 64-bit, then it will be able to address more RAM then your machine can hold. And it seems like CS5 has to head for 64-bit.
What these people have been talking about is the 64-bit kernel which doesn't need to be 64-bit - you can address more RAM with a 32-bit kernel thanks to Physical Address Extension as Pressure noted.
The 4GB application limit would be under K32, not K64 from what I can tell (OS X's memory management).Sorry, but Pressure also said, to quote "any individual application is still limited to a 4GB limit". So by saying "as Pressure has already mentioned" gives me doubts.
In FCS 3, FCP, Motion, Color, Soundtrack Pro, DVD Studio ProRegrettably, I don't have the latest version of FCS, which (I think?) had either Motion or Color as a 64-bit app, or I'd test that right now. I was holding out for the next FCS 8 and will buy CS5 as soon as I can.
