    I know the Penryn 2.4ghz has 3MB cache, but the SR 2.2GHZ has 4MB cache. Which is faster? Remember, I am comparing 2.4ghz to 2.2ghz as well.

    Yes, the Penryn is faster - at least on paper. Exactly how much real-world difference you'll notice is questionable, however.

    no

    because 2.4 is a much lower number than 2.2


    sheesh what do you think

    Actually your wrong about the whole 2.4 is going to be faster then 2.2. If you took a Duel core Pentium 4 at 3.6 ghz and compared it to a 2.2ghz core 2 duo, the Core 2 Duo would probably be about double the speed of that Pentium 4. Anyway in this case Yes the Peryn is faster, the design of the chip is more efficient and therefore doesnt require all that cache. The better a chip intel makes the more money they can save by reducing cache. Intel only has motivation to make better processors. There is more to it then that but Yes the 2.4 is faster then the 2.2

    Clock speeds aren't everything, you know.

    Try comparing a 2.4 Ghz Core2Duo to a 3.4 Ghz Pentium 4, and let me know what you get.

    I'm going from a Merom ("SR") 2.2ghz (4MB L2 cache) MBP, to a 2.5ghz Penryn (6MB L2 cache) - both with 4GB RAM and 7200RPM HD. 128mb VRAM in my old MBP, 512 in the new. Mainly used for Logic/Mainstage, and graphics, and occasional gaming.

    I wonder what sort of speed increase/lowering of CPU usage (in Logic/Mainstage) I should expect with the upgrade?

    Maybe 5% it won't be much.

    I am also going to be using Logic or Cubase. What interface do you have for recording?

    I thought that with the 300mhz jump in raw clockspeed, and the more efficient processor itself, the jump in L2 cache, cooler/more efficient running, and big jump in VRAM, I'd see more than that? Hmm...

    I do most of my music with software instruments, mainly the ones that come with Logic Studio at the mo (and Synthogy Ivory, Vienna Symphony), so I'm just using the built-in.

    I'll be getting some sort of interface for recording vocals/guitar soon though, firewire definitely, just with a couple of inputs - maybe an Edirol? They seem good, and reasonably priced.

    Well, that would be a strawman..we're not comparing 2 different generations of processors, we're talking about a die reduction in size from the same chip family that are clocked at clearly different speeds. I'm going to go with the earlier sentiment that wait for it.... 2.4 > 2.2.

    not much man ... not worth the upgrade. Geekbench numbers between a Merom 2.4 and a Penryn 2.4 are basically the same. I don't think you will even notice the differene.

    As far as the audio interface goes, the apogee Duet with Logic is just a wonder to me.
    Of course if you record more than 2 input at the time then the duet wont be for you. But the whole thing is just amazing.

    I'm in the same boat as you, sold my 2,33Ghz C2D for a new penryn. But i know the upgrade wont be significant, for not much i get a new warranty, glossy led, 4Go ram, HD@7200 and multi touch, so its a steal.

    The Graphics card could make a difference but For right now not too much of a difference the Software must be coded to take advantage of the real power of the processor.

    Ahh OK...I guess Apple will get round to some updates for Logic/Mainstage soonish then, hopefully?!

    Very cool. Never knew that the P4 was that slow!!
