to quote firechild from gearslutz:
As Logic has a different behaviour than other DAW´s, regarding the "learn the song" issue you are allowed to stop and hit play again to be able to get a better "score" in this test. When you can play say 10 cycles without CPU overload when you have muted as many tracks your computer can handle, you have your result.

Did you hit play again after the first overload message? I can get my results much higher with a few more starts

P.S thank you for the results Sir.

Well, i can cramp it up to 24 in 64 bit mode... after a few tries. What was your score?

24 - 30 tracks sounds pretty much in line with the pre Nehalem 4 Core Mac Pros. (which are very capable machines)
Not as bad as it sounds considering its a laptop with a dual core cpu + relatively good battery life.
 
I'm running 8Gb of RAM on a i5 2.53Ghz MBP. Getting 19, can't get to 20 without problems though.

I'm new to all this 64 bit running Logic stuff, what is this 32bit audio unit bridge do? It doesn't change it all back to 32 bit??
 
the 32bit audio bridge will get used when you run 32bit plugins in logic 64 bit. Only 64 bit plugins run without the bridge in logic 64bit.

The results with the the Core ix CPUs don't seem very impressive. It´s almost exactly the same as with the same speed C2D. Strange. Anyone have any idea why that is? Could it be bad multithread optimization in Logic? :confused:
 
That seems really odd!
Firstly with HT on the i7/5 you would expect over 30 tracks to play.
Secondly my Nehalem quad 2.66 shows 8 cores in Logic, why wouldn't the i7/5 show 4, very strange!
This could put off some eager music producer's.... although it makes me feel better about my 2.93 C2D!

might be a logic problem - are there any other daw benchmarks or HT tests?
 
I ran it initially, and got 27. Now I'm having trouble doing more than 24. C2D 3.06 GHz with 4GB running 32-bit 9.1.1.

E2A: Bounced my box and can get 25 easily, 26 with a few overload messages. I think I'm gonna wait until the next rev.
 
Hm...

I think the benchmark is weird in the first place. He's running multiple copies of a virtual instrument (one for each track) and then each track gets its own space designer.

I don't know any real producer/songwriter/musician who uses space designer on every instrument and voice - that's insanity or its just someone who wants a very monochromatic audio spectrum IMO - like everything else I think it's best used sparingly.

That being said:

The other thing, I found my machine would vary wildly from launch-to-launch and boot to boot.

My Corei7 iMac started out with maxing out at 49 tracks. I couldn't get any farther UNTIL I backed out of the app and relaunched.

Then I managed to get to 53 then on a hunch I rebooted the entire works and managed to get as high as 62!

Some other guy over at Gearslutz (the board where this all started) with the same hardware as my own was getting as high as 74 and maybe
he rebooted twice. I suspect it would vary depending on weather and sunspot activity (j/k)!

I think that's part of the problem - the benchmark isn't real world performance - it's just a brute force CPU test that presumes that Logic is optimized for current day cpus and systems and it might have some of that but it's obvious the i5/i7 Macbooks are having issues with Logic.

The other thing would be: can your systems run the 81 track "Spaceman" by the Killers demo? Maybe that's optimized to run on everything but if it can run that it probably can handle a real-world songwriting/production challenge instead of a "brute force" CPU smasher.
 
New Macbook Pro

I have a 2011 15 inch 2.3Ghz Quad Core i7 Macbook Pro, with the stock 4GB Ram and an OWC SSD. It could handle 83 tracks with Logic in 64 bit mode.
