Four years ago, NVIDIA previewed their first ever desktop chipset - the nForce 420 - at Computex.  The anticipation of NVIDIA's entry into the Athlon chipset market at the time was astounding. While they didn't get it right the first time around, by the end of nForce2's reign, VIA had relinquished the throne as the most desirable supplier of AMD chipsets.  Late last year, when NVIDIA announced that they had finally signed a cross licensing agreement with Intel, we knew it meant that NVIDIA's chipsets would soon be coming to the Intel platform, but honestly, we didn't really care.  We hadn't recommended an Intel CPU since the introduction of Prescott and this time around, NVIDIA's biggest competition wasn't VIA, it was Intel - and it's rare that you beat Intel in making chipsets for their own processors.

Honestly, Intel processors and even the platform haven't been interesting since the introduction of Prescott.  They have been too hot and poor performers, not to mention that the latest Intel platforms forced a transition to technologies that basically offered no performance benefits (DDR2, PCI Express).  A bit of that changed when Intel brought forth their dual core plans - assuming that they can actually guarantee availability, Intel is planning to ship more desktop dual core processors, at lower prices, than AMD this year.  As we mentioned in our preview of Intel's dual core Pentium D, the cheapest dual core processors will weigh in at $241 for the 2.8GHz models.  While for the same price you can get a much faster single core AMD CPU, the word "faster" applies selectively depending on what sort of usage models that you're looking at - whether it's heavy multitasking, or mostly running single applications.  We've already had that discussion, and the decision is still in your hands, but needless to say, Intel's processors have all of the sudden become much more interesting given the proposed price point for their entry-level dual core CPUs.  Now all of the sudden, there's some purpose to actually looking at the latest chipsets for the Intel platform. 

We have yet to recommend any of Intel's single core Prescott CPUs, and if you are looking for a single core Pentium 4, then you should already have a good idea of what chipsets there are out there.  But for dual core, the platform support is much more limited.  None of Intel's previous chipsets will support dual core, only their most recently announced 955X and 945 chipsets offer dual core support.  On the NVIDIA side, their nForce4 SLI Intel Edition chipset does support dual core, but NVIDIA stipulates that the motherboard manufacturers must implement that support properly on the design side.  As long as the motherboard manufacturer states that their nForce4 board supports Intel's dual core, you should be sitting pretty.  Chipsets from all manufacturers, including ATI, SiS and VIA will undoubtedly offer dual core support, but the fact of the matter is that their release is further down the line. What we're looking at today are the two heavyweights that are supposed to be available in the channel by the end of this month.

The Delicate Competition

The NVIDIA/Intel relationship is a very interesting one; as with any of these types of relationships, it is not one borne out of love, but rather necessity. At the end of the day, Intel would still be happier if there was no threat from companies like NVIDIA.  Because of this fine line between a partnership and a competitor, NVIDIA has to play their role very carefully - they don't want to be viewed as more of a competitor than a partner in the eyes of Intel.  By selling a chipset that is significantly more expensive than Intel's most expensive 955X, NVIDIA secures their position as a valuable partner, and not a competitor. 

You've already heard that NVIDIA's nForce4 SLI Intel Edition chipset costs about $80, but what about Intel's 955X and 945?  For once, Intel is actually the cheaper alternative - their 955X costs motherboard manufacturers $50 ($53 with ICH7R), while the 945P costs a mere $38.  For motherboard prices, this means that you can expect at least a $30 price premium for a nForce4 SLI Intel Edition board compared to a 955X board; compared to a 945P, you can expect closer to a $40 price premium.  It's not tremendous, but given that motherboards tend to hover in the low $100s, even a $30 difference is significant. 

At this point, NVIDIA hasn't announced any plans to bring a non-SLI version of the nForce4 to the Intel platform, and the vast majority of motherboard manufacturers are waiting for just that.  A lower cost nForce4 chipset would obviously translate into more sales for the motherboard manufacturers. However, it could very well be that NVIDIA doesn't want to try and take on Intel in the same price bracket.  At the same time, NVIDIA is a very successful company, so it remains to be seen how far over the line they will tread in the name of expanding their sales.

    #15 - Score: -1, Troll

    Why are you here then? Hell, you cant even read I guess. I gave you a link talking about heat output when you said it was "opinion" when it was stated Intel runs hotter. I can tell you that from fact from the 25 prescotts sitting in a lab here and when they are all running the A/C better be running too!

    Why dont you come up with some facts yourself instead of insulting both the site and others?

    What makes you think I would care about "a huge landslide of flames regarding your post in this comment section"?

    99% of the people on this site are ignorant cattle without the ability to think for themselves. They are here as part of a communal circle jerk over AMD cpu's. I care as much for their thoughts as I care about the thoughts of the cow that gets slaughtered for my dinner.

    I see we got an Intel fanboy posting in the forums :] Reply

    I see no information in your link that #8's argument. He specifically said that an A64 is faster than Intel in all applications except for video encoding. The link you provided actually proves him wrong, as there are other applications in which the comparable Intel CPU is faster, or the difference is insignificant between the two.

    Oops, sorry...correction

    "...release of the K8 architecture 8 years ago..." should read "...release of the K8 architecture 2 years ago..."

    Sorry about that. AMD's 2nd year anniversary of the release of the Opteron is next Thursday where they will introduct dual core Opterons to the public. Can't wait.

    Oh my God!!! Questar where have you been?

    Go read all the reviews of Intel and AMD processors since the release of the K8 architecture 8 years ago. You have a lot of reading to do.

    Don't give the editor-in-chief of a 8 million plus readership hardware review site advise about getting his facts straight. Anandtech receives and reviews hundreds and hundreds of hardware that you will never even dream of owning.

    If a statement is made in a review from a site as reputable as Anandtech, it is not made lightly. You have all the right in the world to question it and seek a second opinion elsewhere, but it is COMMON knowledge among those reading CPU reviews over the last two years that AMD CPUs are faster in games and computational number crunching whereas Intel excels in audio and video encoding PERIOD.

    You can easily explain these findings. Games and computational number crunching take low latency, high memory bandwidth to work well. Audio and video encoding need fast processor speeds.

    Wait about five hours after the release of this review and you will soon be finding a huge landslide of flames regarding your post in this comment section.

    Have fun! :)

    PS. You must not read at all if you think anyone has found a performance advantage of PCI-E and DDR2 over AGP and DDR for current software applications. Not tomshardware, Hardocp, Xbitlabs, Anandtech, etc. have found a performance increase between AGP 8X vs. PCI-E 16x or DDR400 vs. DDR2400/533/667.

    #9 - You havent been here long have you? Intel does have a performance advantage in encoding applications... but your claims of without proof to others?
    Umm yeah. Pay attention 007.

    And why even claim AGP has no performance benefits over PCI? Ever heard of a shared bus (PCI)?

  • Questar - Thursday, April 14, 2005 - link

    Without proof, it's your opinion. So, find some reviews that showed an Intel cpu being significantly slower than an equivalent A64 in all applications except video encoding.

    I assume you are using an AGP video card. Why? It has no performance benefits over a PCI card. Or is FPS in a game the only way you measure perfomance?

    "Honestly, Intel processors and even the platform haven’t been interesting since the introduction of Prescott. They have been too hot and poor performers, not to mention that the latest Intel platforms forced a transition to technologies that basically offered no performance benefits (DDR2, PCI Express)."

    Your opinion only, don't make this out to be fact.

    That is pretty much fact. In all areas except encoding, they were worse performers than their competiton (Athlon 64). The extra heat sure didn't improve that either. As far as forcing DDR2 and PCI Express, when they didn't improve performance, you can't disagree with that.

    I'm happy you're not the one writing these reviews here at anandtech. :-)

    Go Anand!
