Mac Pro Tower (Nehalem or Westmere)

Because of higher TDP CPU can work longer befor it have to downclock.

No, it means it heats up faster, and needs more cooling.

If u do rendering of video it is good that ur CPU work at max speed.
If we speaking about music production, heavy CPU intensive projects in DAW can kill ur CPU esely

So in other words, it doesnt matter what the work is, high CPU usage is high CPU usage.

so it is good if ur CPU do not have to downclock in the midle of recording.

Which it wont do if you have adequate cooling.

again i repit if something in chain is brouken entire chain will be brouken, so CPU cashe size is one part of this chaine.

There's no 'broken' here in the first place, and from everything youve said, about TDPs, and 'caches being full' etc, you clearly have almost no idea what you're talking about.

[whyterabbyt]

No metter haw many cores and speed of them u have, if CPU cashe is full it will waist it's cicles.

Exactly. Cache misses are a fact of life, and affect all systems, irrespective of speed and number of cores. They're not something which is 'broken' as you keep trying to pretend. And they dont contribute enough of a

An old test indicated that on PIII systems, doubling the size of the L2 cache gave a performance rise of about 4%. That's L2 cache, not L3, which is what youve been talking about, ( and L3 is further away from the processor, so affects speed less directly.)
That's about the equivalent of adding a 26th core to a 25 core system, or less than a third of the standard 'turbo' boost type overclocking an i7 does automatically.
And dont forget L3 cache gets shared between cores. The 4770K has 8Mb of L3, 2Mb per core. The E5-1650 has 12Mb of L3 cache, also 2Mb per core. The slower Mac Pro CPU has 10Mb of L3 cache, less per core than the i7.

Speaking about TDP more TDP u have more CPU can heat with out need to dowclock.

Still. Absolutely. Wrong.

Learn some facts before you try again.

I was wondering if anyone has experience on running DIVA on Mac Pro towers released in 2012. There were two models based on two different Intel architectures: Nehalem and Westmere. One was four core with hyperthreading and the other six core. How would these compare to a 2013 i7 iMac?

Have you seen AnandTech's CPU benchmark comparison tool? Once you have all the specific CPUs in your 2011 iMac, the Mac Pros, and the latest iMacs you can compare them to each other and decide which is your best choice.

(For what it's worth, I have an Ivy Bridge Core i7-3770 @ 3.4GHz and Diva runs very nicely here. I use Windows though so this may be of somewhat limited use to you.)

(uninformed garbage about "cashe" and "cicles".)

(more garbage about TDP and heat.)

Please stop posting this uninformed nonsense, it's distracting and confusing to others. I won't bother to explain cache and TDP to you because whyterabbyt is doing a fantastic job and I know you'll just ignore me anyway.

It's clear you love your new Mac Pro: that's great and I'm happy you have something you like. But the reasons you state that it's superior are just plain uninformed and incorrect. Sorry, sometimes the truth hurts.

Still. Absolutely. Wrong. Learn some facts before you try again.

Keep fighting the good fight whyterabbyt. I'm hoping your posts may one day make an impact.

OP was asking about the old Mac Pro vs. iMac. The new Mac Pro is far more expensive and might not be an option. So why keep pushing?

The new Mac Pro is rather pricey yes. This is why I am enquiring about the old Mac Pro vs newer iMacs. We've gone off topic a bit it seems, however.

there's also the logic benchmark tests that are helpful

most people using the previous model 12 core (or 6 core) are doing just fine and running intense sessions w/them. the 12 core is really a monster.

you could always go to tonymax X86 and get the specs for a hackintosh. they're reliable these days and really fast.

[chilly7]

look like this.

For example
prossesor #1 can withstand 10 units temperature.
prossesor #2 can with stand 15 units of temperature.
When prosssesor goes buyond that temperature it have to dowclock in order not to damege it self.
So in real world Xeons can work at much higher temperatures with out any risk of demage befor it will have to downcklock.

You're confusing yourself. Xeons cant stand 'much higher temperatures'.

The maximum operating temperature of the E5–1650, found in the Mac Pro is 64C (http://www.cpu-world.com/CPUs/Xeon/Inte ... -1650.html)
The maximum operating temperature of a Haswell 4770K is 72.2C (http://www.cpu-world.com/CPUs/Core_i7/I ... 4770K.html).

The Haswell i7 can stand higher temperatures than at least one processor used in the Mac Pro.

And TDP isnt a measure of how much heat they can stand, its a measure of how much thermal power they give off. The higher the TDP of a CPU , the more cooling it needs.

That's why u do not see Xeons CPUs in notebooks because even though it wont be a problem for CPU to be that hot, u won't be able to touch your note book with ur hands.

Except you do see Xeon notebooks.

Facts. You lack them.

Thank u for trying to correct me!
Well i do not know maby u are right. I am not a computer technition.
But better i will put all my time on music in order to make it as best as possible!

[chilly7]

chilly7, discussions with you are really tiresome.

That point about cooling is moot. The cooling is great but it has to be because the TDP for the CPU requires better cooling.
I have first hand experience which says that the iMac is just as quiet as the Mac Pro. Cooling is not an issue, noise is not an issue.

And no matter what you just wrote, you were saying that cooling was an issue before. That i7 CPUs would clock down within 2-5 minutes. That's not true if cooling works fine which it does. If you can't stand people correcting you, don't talk about things you don't know anything about. Because people will call you out.

OP was asking about the old Mac Pro vs. iMac. The new Mac Pro is far more expensive and might not be an option. So why keep pushing?

And please, can you please spell things correctly? It's completely obvious that you know how to spell. You do in one sentence, you don't in the next.

I alway welcome somebody who trying to help me to find how it is in real!!!

Speaking about cooling, befor my new cilinder Mac Pro i used my mother's Mac Book Air and CPU can work on max performance for very short time. I expect that new Retina MacBooks and new iMacs have better cooling, but i do not think it is as good as in new Mac Pro. So that's why i highly advice to take a look at new Mac Pro. Because it looks like it can work on max CPU performance with out downclocking and be not hearable, while i do not think MacBook or iMac can do that.
That will be pretty unoying if u hear fans during music production!!!

Learn some facts before you try again.

Cashe architecture has changed since Pantium 3, so there might be less bottle necks with cashe accsses. New Haswell CPUs have even fester cashe.

So if i am wrong please correct me, but with arguments and evidences! And i will be happy if sombody will help me to find the truth!!!

I will advice u new Mac Pro just because it is supper silent.
While iMac, or MacBook can have fan noise which u might star to regred that u bought over new silender Mac Pro.

And also if u do heavy projects with high end plugins top i7 in iMac might not be enough for u, but in Mac Pro u can upgrade CPU up to 12 core IvyBridge Xeon E5 ( Haswell won't be able to instal because it has different socet)

Hakintosh is illegal the same as ranning Uhe plugins with pirated software.
So Hakintosh is out of diss discussion!

You've been corrected, with arguments and evidence. And I must say, its pretty ironic of you to mention the latter considering your own consistent failure in that respect.

If i was wrong i would happily admit that, because my goal is to find truth!!!
