audio processing problems resolved for IMAC I7

    Hi everyone,

    I will be buying my first computer studio and want to go with the IMAC I7. But I ran into some forums referring to Audio Processing Problems with the I7; using more cpu than should, loud fans, problems playing itunes, ect.:confused:

    I was wondering if the recent update(s) completely solved the related audio problems? Can the I7 run Logic 9 without any hardware problems? I know that if anyone can answer this, LUG can.

    I have a limited understanding of computers. But I NEED to make sure that I get this computer purchase right and cannot afford to make a mistake. Nor can I afford the Mac Pro.

    Please share your experiences with the I7 or your suggestions.

    Hi,
    Well for starters, the only Mac that has the i7 based CPU is the Mac Pro. The iMac has the i5 cpu in the most costly model.

    Is that what you were trying to ask about, the i5 based iMac?

    Just to clarify this, it is in fact possible to order the imac with the i7 quad core processor (go into the Apple store, select the 27" 2.66 quad core model, you should see that you can order it with the 2.8GHz Quad-Core Intel Core i7). The current generation of Mac Pros use the Intel Xeon Nehalem processor.


    kind regards

    I don't own the i7 imac myself, but a friend who recently bought one seems to be pretty happy with it. He mentioned running at 32 samples, 44100 sample rate, Process Buffer set at SMALL, an EQ, compressor and Space Designer inserted on EACH TRACK, he could run 63-67 stereo tracks before getting an overload message. Apparently, the machine is almost completely silent.

    kind regards

    The strange thing about the new i5 or i7 macs is the apple site says there are only 2 cores per cpu... and from what I can see at the intel site, the i7 are only quad core.

    I'd be sure to get that one cleared up no matter what way you go.

    Hi George

    Perhaps this helps:

    Well I was just at the apple site and checked the specs, and then (about an hour ago) i checked out what I thought were the specs and came across this:

    The Intel Core i5 and Core i7 processors are based on new 32-nanometer process technology with an advanced Core microarchitecture that features an integrated memory controller and Level 3 cache, giving the MacBook Pro faster, more direct access to memory. In addition, these processors feature:

    Turbo Boost - a dynamic performance technology that automatically boosts the processor clock speed based on workload, giving you extra processing power when you need it.
    HyperThreading - a technology that allows two threads to run simultaneously on each core. So a dual-core MacBook Pro has four virtual cores, all of which are recognized by Mac OS X. This enables the processor to deliver faster performance by spreading tasks more evenly across a greater number of cores.
    You can upgrade the processor in your MacBook Pro to the 2.66GHz Intel Core i7 processor -- the fastest dual-core processor available, featuring a 4MB L3 cache and Turbo Boost speeds up to 3.33GHz.

    It is for the mac book pro, and I am almost sure I saw the same thing on the iMac info in the system builder at Apple Store. When I just looked, it was the same as you showed... getting a bit foggy brained (doh).

    All that said, if it's a 4 core i7 it'll be pretty fast, get lots of ram though.

    The confusion comes from the fact that the i7 CPU is available in several versions, in both 2 and 4 cores.

    The "mobile" ones, due to lower energy usages, has 2 cores.

    So the iMac with i7 CPU have 4 cores, the MacBookPro with i7 have 2 cores.

    The main difference between the i5 and the i7 series is the much faster memory bus.

    I bought the iMac i7 4 core with 16 GB RAM to use as a slave machine on a secondary setup in my studio. Before I even got the iMac integrated into my setup, I had to return it to the Apple Store to have the screen replaced because it had developed a vertical line of dead pixels that ran the length of the screen. This is a common problem with the iMacs with the new... gorgeous... LED screens. The Apple Store replaced the screen the same day that I brought it in.

    The iMac is pretty quiet and I'm looking forward to finally getting it up and running.

    Thanks everyone for your input,

    It seems like the I7 is indeed a solid machine:D

    Please keep your experiences (good or bad) coming as I won't be making my purchase until late next week.


    P.S. I'm loving this site, everyone's very helpful

    Thanks Mark, That's awesome!!!Even with my limited knowledge I realize that is alot of tracks with a small buffer,EQ,Compressor,Space Designer on EVERY TRACK
    For What I need it for it's probably overkill, But I guess you can never have too much computer power or too low of Latency.
