Apr 7, 2012I am planning to get a Macbook Pro 17" and It seems im just itching to get one but i also want to know if the 17 inch 2.4Ghz does turbo boost cause it says on the 17" 2.5 GHz it does 3.6GHz on turboboost with 8mb of l3 cache. Generally Im just asking can the 2.4 GHz version of MBP 17" do Turboboost and what would be the speed when truboboost is active if ever it has one?

Jun 17, 2012MBA2012 Corei 7 2.0GHz/ MEM 8GB / SSD 128G.
core i7 3667U, it support turbo boost, max multiplier 3.2GHz (x32, 2core), or 3.0GHz(x30, 1core).
but check cpu-z 1.60.1.x64, it reports cpu multiplier x8 or x19. core speed does not rearch 2.0GHz(x20) and can not turbo boost.

Mac Pro :: "Turbo Boost Dynamic Performance (up To 3.33GHz On 8-core 2.93GHz System)"?
May 5, 2009Under Tech specs for new 2009 Mac Pro:
"Turbo Boost dynamic performance (up to 3.33GHz on 8-core 2.93GHz system)"
As this is a feature of the chip I'm assuming this is true for the new Quad core as well. Is it? How can I find out? Any online reviews/overviews/etc. that looks at the new chips?

MacBook Pro :: How To Install OCZ Vertex TURBO In (Mid 2009)
Aug 3, 2009I'm planning to order + install a OCZ Vertex TURBO (128 Gb) in my new MBP. Unfortunately, as these SSDs are still fairly new, I could not find any information from people who have experience working with them, let alone working with them on a MBP.
Does anyone have one of these, and have you encountered any problems? Or would you not recommend buying one of them, and go for the OCZ Vertex instead (which seems to have a larger user-base).

Sep 19, 2010m 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.

View 11 Replies View RelatedMac Pro :: New Barefeats Tests For Nehalem
Mar 11, 2009Looks 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.
Mac Pro :: Nehalem Memory -- 6 Is Better Than 8 Sticks?
Mar 15, 2009Last 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.

Mar 16, 2009Can 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.

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.

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.

Mac Pro :: Possibility Of Replacing Processors/Harpertown To Nehalem?
Nov 20, 2008I 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?
Mac Pro :: Logic Board - Dual Nehalem Processors
Mar 18, 2009Does 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??
