What about Quad Core?

Later this year Intel will be introducing pin compatible upgrades to its Core 2 and Xeon lines, except instead of two cores these processors will feature four.  Codenamed Kenstfield (Core 2) and Clovertown (Xeon), Intel's new quad-core processors will dramatically increase the amount of processing power you can have in a single system.  Given that the Mac Pro features two LGA-771 sockets, you could theoretically drop two Clovertown processors in there and you'd have an 8-core Mac Pro.

Without a doubt Apple will release a quad-core version of the Mac Pro, either by the end of this year or early next year, but are users who buy the Mac Pro today missing out?  While we're still a couple of months away from being able to test a retail Clovertown CPU in the Mac Pro, we wanted to see if the current engineering samples of the chip would work. 

We grabbed a pair of 2.4GHz Clovertown samples and tossed them in the system, and to our pleasure, they worked just fine.  Our samples used a 1066MHz FSB, although we're expecting the final chip to use a 1333MHz FSB, but the most important part of the test is that all 8 cores were detected and functional. 

We ran a handful of stability tests on the Mac Pro equipped with two Clovertowns and didn't encounter any crashes with the processors, so it would seem that Clovertown will work in the Mac Pro's motherboard.  We can't say with 100% certainty that you will be able to upgrade to Clovertown when it comes out, but so far the results are looking good. 

For the performance of Clovertown you'll have to wait a bit longer as we're not allowed to disclose it just yet, but we wanted to let you know that so far it's looking like you'll be able to upgrade your Mac Pro to 8 cores in the not too distant future.

We are expecting there to be a trade off between clock speed and number of cores with the move to Clovertown, meaning that you'll be able to find higher clocked dual core Xeons than the upcoming quad core models.  The current rumors suggest that on the desktop side, the highest clock speed quad core chip will be 2.66GHz while the fastest dual core CPU will run at 2.93GHz.  We'd expect a similar situation with Clovertown in the Xeon lineup, meaning that unless you have a way of really stressing 8 cores, you may be better off with 4 faster cores in your Mac Pro.  We definitely had a difficult time stressing 8 cores in the Mac Pro, but if you have a handful of well threaded, CPU intensive tasks then a pair of slower Clovertowns can easily outperform a pair of dual core Woodcrest based Xeons.

    Yesss, the same old situation, Mac for vídeos and a PC for games, Microsoft and others when the Mac was not X86 always tried to put them on the Vídeo maker market, 2000 and XP takes place in an big users base, but they are always telling you the same thing, use a Mac. Windows is limited.
    I´m the Ceo of Grey Silica Brazil. I´m specialized to work with Blender (A Now GNU program to 3D content Creation for films and presentations ), and tested every possibility of those "dream machines" when they are on the market with their S.O.s. All I have experienced is that windows XP is a shame compared to 2000, 98 is a never think software for 3D services, although I have to use some times in 1999. Some capture cards simply doesn´t function on NT or even 2000 because of drivers.
    But leaving this question I Guess when 2000 was launched Microsoft did a very Good O.S.
    XP introduces spywares to the market, as Hackers wanted too to sell information to others to make money, the same thing as Microsoft does with their partners. You register your software to activate it and a Database Knows what machine you have, the memory you are using, the programs you have installed, the VGA card, etc, etc.
    Windows XP takes this information to sell to others and everybody knows that, course, you have to accept to use... Linux is still on the road, money mekes this world, pressure to not gave information to linuxers is a bad, bad thing.
    Well, Win 2000 now takes those information too, when you download Windows Update services, and WGA have to be installed to 2000 too in some cases. OK. When needed. But it happens now, and not when 2000 was launched. 2000 is not a bad example for hackers.
    If I am a hacker, course that I will think in the same way, I will create my own .net passport with the information hacked or stolen from them, if they buy Nvídia, tell my partners " Buy Nvídia, they sell well !".
    It´s a PC world created, not a MAC bad example. My admiration for the Mac world too, like Anand, Mac not created this monsters of vírus and spywares, they did not do this bad example to humanity collecting data in this way and serving as a sample to hackers.
    The other major problem is limiting the users, 64 Bit can use 128GB of RAM or more, Vista is 64 GB caped, and blogs are saying 4GB is for the kernell. UAU !!!
    OMG !!! 4GB for the kernell, astounting.
    Why they want to limt the users, when Mac and Linux are on the other road ?
    Obvious... To sell other S.O.
    Windows will be a Game console System in few years this way, not an S.O. great to work like they ever swear to you.
    Compare XP to 2000... They can do exactly the sa thing, but 2000 does it better and faster, complimentary software do not leave you to oblivion, Who needs I.E. 7 ehwn Firefox is better and oppen ? Who needs simple compacted folder included in explorer when 7-zip opens more files than you can imagine ?
    Who need My pictures when corel snapfire is better ?

    2000 is the best windows. Fill him with the right software and you will have the most powerfull windows ever.

    Leave MAC for MAC OS-X or Linux, when they gave you hardware that is capable of 128 GB, the OS will achieve this and will not limit you. Will you use Vista knowing this ?

    I have to agree with the first part of your post. I read the article and thought.."Why?". I have always understood the appeal of a Mac to be that you could upack it and get to work. If we start talking about running other OSs on a Mac or hacking software/drivers for better hardware supprt, then why pay the premium for a Mac? Reply

    Because a Mac is cheaper than an equivalently configured dual dual-core Xeon workstation from Dell orr HP? Reply

    I see the rendering results and I Think its really will be a dream machine for 3D Rendering and not a gaming dream machine like allienware ( Now dell ) is, and therefore are a bunch of problems into running XP in this hardware that is not related here, XP is caped to the switch of 3GB and limited to 2GB per app, it´s nearly impossible to compare XP with Mac OS-X, the other downside is that I Didn´t see any review tolding you that you can read XP partition under Mac OS-X or even write to it.
    I Have so many doubts that windows Vista will not be caped in some way after seeing that the switch can really prejudice us to upgrade to another OS that MS is trying to sell.
    I will only switch my opinion about Microsoft when they finnaly release a patch to solve this caped windows in relation to this memory issue under adressing really what the hardware can do. If Mac OS-X haves 16GB of memory, XP only will see 3GB and 2GB per app, PAE ( Page adress extension ) is a nightmare for users and a dream for Microsoft.

    They are saying for all of employees now:
    - Memory Issues ? Push them to Vista !!!

    And it is not all, I discovered that windows 2000 is stronger than XP under heavy loads, and abandoned XP to rendering services, Linux, Mac OS-X and 2K are the best choices if you are a 3D professional and you hve a good workstation.

    Mac-OS-X have its own problems too before 10.3/10.4, it´s limited too to 2GB per app. But right now this is completely solved, giving to you all of your machine.

    I Have certainty to tell that professionals will really benefit from 2- quad core clovertowns under 3D content creation.

    XP was not designed to meet professionals demands, its a S.O. to play games.
    Then, do not polute your Mac, and do not buy a mac to use XP, use a budget computer that deserves XP if you wish to use this.

    If you are a pro, use windows 2000 instead of XP, it´s faster, reliable, secure.
    Windows 2000 helps your productivity. Course... Without the cosmetics...

    Are there any decent 64-bit rendering apps like Maya/Lightwave/etc that run natively on XP x64? Reply

    After seeing what you've said about wishing for a C2D/DDR2 Mac, I'd be interested in how the new iMac C2D with perhaps the 7600GT option stands up in gaming to a comparable PC. Sure, it's nowhere near as configurable (or as boast-worthy) as a Mac Pro, but it does seemingly offer a solution somewhere in the middle.

    That said, the 24" iMac is the only one currently supporting a 7600GT upgrade, and it does boost the price a bit. On a cost - performace ratio, in GPU-limited applications the Mac still seems to be overpriced compared to a PC.

    For interest's sake, however, it's something I'd read carefully.

    Just wondering, what's the stepping on the Clovertowns used? Reply

    I am not entirely convinced of the apple craze. I still prefer my own customability of my system and XP is really not a bad OS to work with. That and I am cheap and really dont want to shell out money for the apple package deal they have going. Reply

    I just want to tell you that the MacPros are workstations - and their price reflect that. You buy one for lots and lots of reasons, the last of them are games.
    Those are used to make money - and in some cases, having twice the horsepower lets the employee that use them work twice as fast.
    I do prefer my own customability of my system (even if I barely used it), and XP is (now) not a bad OS to work with. But MacPros are for me just as much as an SGI Octane would be (very useful for tasks I wouldn't touch with a barge pole)

    What the hell are you talking about :*(

    Windows Workstation with the same spec that cost cheaper could do everything that Mac workstation could do :*( only real real reason i would buy a new Mac pro if i was Video editing.
