Mac Pro :: Initial Intel - Nehalem - CPUs
Jul 14, 2008
Quote:
Pssst! Want an Intel 'Nehalem' processor on the cheap? Well, just go and ask the chip giant for one. It's 2.66GHz 'Bloomfield' CPU has been price at just $284, it has been claimed.
That's the batch price, of course. To get it, you'll have to buy a 1000 CPUs at once - boxed Bloomfields will come in slightly higher than that.
As previously reported, the 2.66GHz Bloomfield - Intel's desktop Nehalem - will also be made available in 2.93GHz and 3.2GHz versions. The pricing, posted by Chinese-language site HKEPC, confirms the latter will be an Extreme-branded gaming PC part - it'll cost $999. The mid-range Bloomfield will cost $562.

I have recently bought 2 4GB 1333MHz memory to be used with my Mac Pro mid 2010 nehalem processor. It works fine, turns on and all, but after opening a few programs and letting it run a little and i ask him to shut down, it takes me to the grey screen with the little rolling ball and does not shut down.
Info:
Mac Pro (Mid 2010), Mac OS X (10.7.4)

I was just wondering... do CPUs get slower over time? For example, if someone's computer is doing a ton of video encoding or compiling, would the CPU get slower?

I bought this in early 2007, it's 2 CPUS (2cores each) making it a quadcore machine... i was wondering if i could upgrade the CPUs. woodcrest made 3.0ghz processors, but unsure if they are still just 2cores or 4 cores each

Bought my IMac a year ago, got the applecare plan and am good until 2014; however, it would be great if I could renew my applecare plan after the initial plan. or just before, the plan expires. The applecare staff is great to deal with, but it's a nice feeling to know that I can access them after the first 3 yrs. of ownership. I bought my IMac with the knowledge that I wouldn't need to upgrade my hardware as often as I did with a PC, and although I understand I can still recieve assistance on a case by case basis, it would be easier, and more cost effective, to have the option of extending my plan if I choose to. Just a thought. and am hoping that Apple will listen and offer something for its customers like this. Am an owner of the IMac, and IPad2, Ipod touch and will be buying an IPhone 5 when they are released.

m having trouble deciding between these two models. Might get the 3.33 Ghz 6c Westmere but leaning towards the 8c models. Why is the 2009 Nehalem faster? The guy at the Apple store was suprised by that also. Are there any changes in the 2010 2.4 8c Westmere from the 2009 Nehalem model?I will be using it for intensive music software (Prottools, Digital Performer, East West, Symphobia, Vienna Symp Inst. All web and graphics software (Photoshop, Flash, InDesign, etc and Astronomy programs)

Looks like the 2.26 is doing better after all. Some users have even gotten Cinebench scores for the new 2.26 like: 3142 (single) and 20,138 (multiple) reported here.
CINEBENCH 10
This free benchmark app uses real world code from Cinema 4D to render a sample project. It stresses all available cores. In the case of the Nehalem, hyperthreading fools the app into thinking there are 16 cores on the 8-core models and 8 cores on the 4-core models. The graph below shows the Cinebench rating for "Multi-CPU" render test.
GEEKBENCH 2
It's not only multi-core aware, but it includes some memory tests which explains why the Nehalem based Mac Pros beat the older Penryn based Power Macs with higher core frequencies. The graph below shows the overall 32-bit score.
There is also a 64-bit version of Geekbench. Fewer results exist for it since, for some unexplained reason, consumers will gladly spend thousands for a new Mac but resist purchasing a $20 serial number in support of a starving Mac developer.

Last night Lloyd Chambers of [URL] tweaked his DigLloydTools app (DLT) that we use to test memory throughput. It's now more accurate. The bad news is that it showed that when we put 8 sticks of memory in the 8-core 2.26GHz Nehalem, our throughput for memory read/write (memmove) dropped by 1/3. It turns a triple channel memory bus into a dual channel memory bus.
Specifically, in our test, the combined read/write throughput dropped from 9261MB/s to 6195MB/s when we went from 6x2GB to 8x2GB configuration.
Now, don't panic. That doesn't necessarily affect real world app performance unless the particular app you are running is saturating the memory bus. Which apps saturate? I don't know yet. I'm running our complete real world test suite including Pro Apps and 3D Games in both the 12G and 16G config. If I find anything that's significantly slowed by the 8x2G config, I'll post it here as well as on Bare Feats.

Can you upgrade the processors in the new Mac Pro's in the future if you choose to?
I have seen a couple people mention to but the 2.6 for now and upgrade them in the future when the price of the processors drops.
I didn't know if I was misinterpreting what they were writing.

I have built a hackintosh mac pro 3.1 on dell T5400 and working good. Now I wan to build a real mac with mac parts. As titled, will there be any switch to make the single cpu working on dual cpu board, OR no way, that I need to put two? Or it's even simpler just boot the machine with one cpu left on board. Since putting 1 cpu save lots money for me.

I want a mac pro is for storage space and to play games on. I want to use a GTX285 and I also want to run vmware fusion full time. I'd like to have OS X be my main os with Windows 7 and Ubuntu running in the background. So basically i'm not sure if it's better to have like four cores dedicated to Windows 7/Ubuntu while i have my other set of cores dedicated to OS X?

I'm planning on buying a MacPro soon.
I'm considering buying a refurbished 8 core with the idea of upgrading the processors on a year or two when they are cheaper.
Is this possible (replacing Nehalems with Westmeres)?

I remembered that at one point Mac Pro's CPU was a direct successor to its previous model, as in you can buy one of the successor chip and replace the older one, since the MLB could support it.
Is this the case with Harpertown to Nehalem? Can you just go on Newegg and get 2 Nehalem, and throw them in to the current Mac Pro?

Does anyone know if the logic board is the same for all current dual nehalem processors offered by Apple? Or does the dual 2.26GHz quad have a different logic board than the dual 2.93GHz quad?
It seems like if they have the same logic board you could buy the dual 2.26GHz now and down the road you could buy the dual 2.93GHz chips (when they aren't $2,600 more) and just replace the dual 2.26GHz chips. Maybe it's not that easy, but if it is it seems like a great alternative to buying the top machine right now. Does anyone know if this is possible??

I just found THIS
http://www.maxupgrades.com/istore/in...ategory_id=343
where they state that the max RAM is 16GB. Do they KNOW something? This would throw up in the air all my thinking about which MacPro to buy.
I am an old Mac hand (and before, Apple IIe, IIc, then Mac 128, 512, Plus, Se, IIx.... to a Dual G5 1.8GHz now), but a total newbie as far as Intel is concerned, so please pardon me if my conjectures are completely off whack, and for the large number of questions.
Looking at the ill assorted (in my view, particularly pricewise) lineup of the latest Pros, I have come up with the following ideas:
- Buy a quad 2.66 with up to 8Gb and be happy for the time being (I have 2.5GB now), with better single thread performance than the 2.26 and still 8 thread performance available WHEN there will be apps to use it (none/few of those I use do, as far as I read around, in any case, and even those seem to stop at 2/4 cores anyway).
- IF the 4GB sticks work (I know this is a big if, but given what I just found, there might be hope....), buy them at a later stage when they come down to an acceptable price and get to 16. I see a lot being written around along the lines �Even if they work, they cost more than the computer today.... etc, but RAM prices normally go down fast, so is this really an issue (except if you need 16GB NOW, of course)? And arent 8GB sticks likely to appear later on to get it to 32 if needed?
-Buy a used 2.93 or faster chip in 2-3 years. I have no idea of how cost effective this has historically been. Do prices go down significantly, or am I likely to get in the ballpark of the delta with a used, faster machine, as it often happened in the past with CPU upgrades?
-Are future chips likely to be compatible with the current machine (can someone who understand the Intel roadmap shed some light here?), or would I be limited to the 2.93 which is known to work?
-In case the 4Gb are proven to be unusable and I go for the octo, can changing chips work by replacing the 2.26 at a later stage? Knowing that I would need to buy 2, would the economics still work? It seems more unlikely, or is it?
-I remember reading about using the graphic card chip to reinforce computing power. Is this fact or forecast? Is this true of both Nvidia and ATI or (as I seem to remember) only Nvidia? If so, is it better for the long term to choose the cheaper standard Nvidia or the ATI, which seems better right now?
-Does any of these cards give an advantage over the other NOW in Photoshop, iMovie, Aperture (I have tried it on my G5, but scrolling a large collection of photos is a pain)? I do some video but no #D, nor do I think I will do in the future.
-Last quesstion for those who have a 2009 Pro in their hands, I have had always problems with USB peripherals on my G5. At some point the bus slows down to a crawl, with transfers of 1Mb/s. According to a local vendor the 2008 Pro was similar because he said it was a limitation of USB architecture, is this true? Has there been any improvement with thee better memory architecture of the 2009 Pros?

At any rate, does anyone know how many FLOPS the new Nehalem-based servers push? I'm in the process of designing a high-end server cluster and I'd very much like to be able to use Xserves; however, I cannot seem to find any good performance data (I'm looking for numbers here).

I don't keep my computer on 24/7. Lately, when I start it up, it restarts on it's own. Sometimes, it seems to get through with the initial start up but shuts down & restarts after about a minute. Sometimes, however, it doesn't even finish the boot up process when this happens. This usually will happen over & over again a many times. The only short term solution I've found, is to unplug my computer, then restart it after a minute or so. This has not permanently fixed this problem however, because the next time I shut off, it happens again.

I was wondering if there is a way to disable the login prompt every time I close and open my MacBook Pro screen? I do not mind the initial login screen, when I just turn on my laptop but having to do this every time my computer goes into screensaver mode or I close the screen is annoying, especially in class. So could anyone help me out on how to avoid and disable this?

With the Apple sign and the timer spinning. I am unable to get to the screen where i can input my password at all. The macbook is about 6 months old and is running on Lion. whether this is hardware, software or virus? I have tried some different key press combinations to reset the MacBook to factory default setting but the problem is, no image was taken of the macbook in time machine and when bought, it did not come with a disc with OSX on.
