Hi Guys,

 

Long time no see! Wanted to seek just a bit more advice on my imminent 'puter purchase from the denizens of this fine Logic establishment!

 

In my ducky sights: the 6 core (3.33) or the 8 core (2.4)

 

I'm aware that the 6-core only supports up to 32G of RAM as compared with the 8 core. That's a decision I'm wrestling with. Other than that, I can load it up with all the same # of hard drives and PCI-e cards, so that's fine. A few notes... not interested in waiting for a new model to show up (need a new 'puter asap), not interested in Thunderbolt. Highest OS I want to deal with is Snow Leopard. Want to run Logic 8.0.2 as well as 9.1.3. Doing lots of orchestral work, but (from a RAM perspective) I've never been one of those guys who loads up every articulation from the outset. I load 'em as I need 'em.

 

I'm also going to hold on to my PPC Quad and use it as a satellite running VEP.

 

I read another thread in which pancenter, Mike Connelly and spheric offered some great perspectives on the 6 v 8, but the thread's a little old now (as well as "archived"). So "let's take it from the top one more time, boys!" Which 'puter would you recommend?

 

Regards to All,

    Rumor has it that the Mac Pro will be upgraded around August.  If it were me I'd definitely wait, even if it just gets SATA III and thunderbolt that would be a big improvement.  And if you don't need whatever the new version brings, the old one will go on sale.

    Mike,

     

    Does OSX and Logic now take full advantage of the 6 core machines?

     

    I'm guessing the bus speed on the 6 core trumps the bus speed on the 8.

    I know the 8's are proven, solid machines but I'm attracted to the fast 6 core as VI and effects should do well with the fast CPU and bus.

    Well? You don't need much RAM, but a limit of 32 GIGAbytes may be a problem?? Have you ever counted 32 gigabytes? They're a whopping 256 gigabits you know!

     

    Hexacores are becoming more "clotting edge", but still I would go for the two by four: 16 cores vs 12 cores. With Logic, I'd prefer more but slower cores over less but faster. And though the hexacore outscores the 2x4 in Geekbench (14,000-ish vs 12,000-ish), the benchmarks for Logic give the 2x4 the edge:

    And now for something completely different:

    pancenter-

    I haven't used a 6 core but everything I've seen suggests Logic uses all cores just fine and it performs very well.  The current Logic uses all cores including HT on all machines but the 12 core (where it maxes at 16).

     

    The 4 ram slots isn't great (especially if you want to keep the ram triple channel which limits you to 24 gigs), but now the 8 gig chips are cheap enough that it's not as big a deal as it used to be.  And while 32 is a lot, there are libraries that can use that much.  Maybe now its more than enough but as sample libraries get bigger I expect there will be people who will need more than that.  Right now I'm running 22 gigs and that's a good fit for me, but I can see needing to go higher when I get bigger libraries.  The flip side is down the road putting libraries on SSD should allow lowering the buffer sizes and use a bit less ram.

     

    In benchmarks the 8 and 6 seem pretty close.  But using Logic I rarely run out of power loading up all the CPUs, the limit I usually run into is playing in a track and Logic spikes the CPU on one core.  For that reason I'd probably go with the 6/3.33 since the higher clock speed gives more when Logic puts lots of load on one core.  But that's just if I absolutely had to buy today, otherwise I'd definitely wait and see what the next generation brings.

    Erik,

     

    Except for the water, tree and green grassy field........ that looks like where I live.

    Hi Mike and Everyone,

     

    Thanks for your replies!

     

    Mike, I really appreciate you sharing your perspectives on the 6 versus the 8. I hear ya about waiting for the next gen of computer, but I imagine that it would be shipped with Lion and I'd be concerned whether Logic 8.0.2 (my preferred version) would run on it.

     

    I discussed this with an Apple rep a few weeks ago, and he said that he couldn't predict if 8.0.2 would run on Lion. OK, fair enough. When I asked if I'd be able to install Leopard or Snow Leopard on a next gen computer he said "no", explaining that the motherboards of any new model wouldn't support running an older OS.

     

    I'd be curious to get your take on that.

     

    With Much Appreciation,

    "Purchase Decision Looming"

     

     

    Interesting choice of words... Looming... a sense of foreboding.    A bit ominous sounding.

     

    Do let us know your final decision.

    Hey, like, you know, I'm a film score composer. If I can't evoke a sense of the dramatic then what would I be? I'd be [sniff] nothing, nothing at all .

     

    Then again, I'm more partial to romantic comedies but I'll take a serial killer film if one happened to cross my doorstep. Chianti anyone? Chianti?

     

    (Aw jeez, there I go... I don't post on the forum for the longest time and when I come back, what do I do? I start rambling. Can ya stand it?!)

    Good point about Lion, I assume 9.x should run fine and either the previous update was tested on 10.7 betas or there will be an update for the new OS.  Logic 8 I haven't installed on my intel box when I moved from my G5 so I don't know what to say about that.  I have been happy with 9 and it definitely has had updates specifically for the new machines.  When you make the switch to new hardware you may want to give 9 another shot.

     

    One thing to keep in mind is even if you end up getting the current model, once the new machines ship the prices should drop a bit on the old ones.

     

    So is anyone here running the 10.7 beta with Logic 8 or 9?  Or seen info about it elsewhere?

  • 10. Re: 6 vs 8 Core Purchase Decision Looming
    iSchwartz Level 5 Level 5 (4,315 points)

    The eventual price drop is something I'd love to take advantage of, but need trumps the potential savings at the moment.

     

    As far as Logic 9 goes, there's certainly lots to love and I'll install it on my new system. But as far as using it as my main version, no can do, sadly... There are three or four functions that have changed drastically compared to L8 and I can't deal with those differences. I won't bore you with the details, but save to say that when I compose on Logic 9 I feel like I'm walking up a sand hill, whereas on L8 I'm being carried along in a sedan chair.

     

    OK, maybe that's a bit inaccurate... Out of the four sedan chair carriers, one of them walks with a limp, and another one has to stop every few blocks to re-tie his shoelaces. But other than that...

     

    Great, thanks again for the perspectives and advice.

    Ta da. Thanks again to all of you who offered your insights/advice. I'm now one MacPro 8 core 2.4 with 20G RAM heavier. I have to say, it does purr.

    Congrats!

     

    What OS version are running.

     

    And Logic?

    Thanks!

     

    Versions... I updated my profile to reflect the new stuff but it's not showing up. I'll tinker with the controls and see if I can make that appear. But for now...

     

    Logic 9.1.5 (just updated this evening from 9.1.3)

    OSX 10.6.8 (just updated this evening from 10.6.7)

    20 G RAM (the original 4 that came with the computer + 16G extra)

    Three additional 1.5T hard drives (projects, samples 1, samples 2)

     

    I also have Logic 8.0.2 installed on it.

     

    Hope all's well with you!

     

    Best Regards,
