nForce3-250 - Part 1: Taking Athlon 64 to the Next Level

Conclusion
nVidia was roundly criticized for the lack of up-to-date features in their first Athlon 64 chipset. That criticism turned to utter disappointment when enthusiasts discovered the additional overclocking limitations of the 600MHz HyperTransport and the non-working AGP locks on motherboards that appeared in the marketplace. In fairness, performance at stock speeds was just as good with nForce3-150 chipsets with Athlon 64 as it was with competing chipsets, but this was not what we have come to expect from nVidia on their chipsets for AMD. nVidia says that they never expected AMD sales to take off until the introduction of Socket 939. It is very clear that nForce3-250 was designed first for 939, and the fact that we are seeing it now for Socket 754 is only because you can now buy 754 and Socket 939 is still probably a couple of months away.No one can complain about the feature-set of the single-chip nForce3-250. It competes with any chipset that we have looked at or heard about. We were also excited to test a Socket 754 board with the Ultra chipset providing the option of not just 800 HyperTransport, but the 1000 HyperTransport that we will be seeing when Socket 939 is introduced. We expect that some enterprising companies who cater to the computer enthusiast, will slip in some Socket 754 boards based on the Ultra chipset with a Gigahertz HyperTransport.
The ultra-speedy on-chip Gigabit Ethernet is more than a checklist feature. If you are a LAN gamer or transfer large files on your network, you will find the speed truly impressive. Removing LAN from the confines of PCI is an idea whose time has come, and nVidia's solution is the fastest on the market. The on-chip Firewall is also a great idea that will be appreciated particularly by LAN gamers. nVidia won the hearts of die-hard gamers with nForce2, and they certainly will win them back again with nForce3-250Gb. No matter how you look at nF3-250 features, there is a gamer in the background who nVidia is trying to satisfy.
The Raid controller capabilities of nForce3-250 are a quantum leap over the integrated home storage solutions that we have seen thus far. Intel will also introduce much-enhanced storage capabilities with their upcoming Alderwood and Grantsdale chipsets, but nVidia certainly impressed us with their hot-spare and on-the-fly rebuild demonstrations. However, we think most users will find the controller that treats IDE and SATA drives the same - allowing them to be combined in any way - to be the most useful feature that they have seen in a long time.
If you haven't figured it out, we are impressed with the features of nForce3-250Gb. They are much more than fluff and check-list items; users will find many features truly unique and truly useful. In Part 2, we will take a closer look at the performance of nForce3-250GB. We will compare performance to other Athlon 64 chipsets and take a closer look at how ATI and nVidia graphics compare in performance on nForce3-250.

Yes, the lack of PCI Express is a disappointmentBut, so is the lack of PCI-X. It means that system integrators and postproduction facilities will be hesitant about using NF3-250 motherboards for workstations because a significant portion of the current NLE cards want at least a 64-bit PCI slot, if not a PCI-X 66, 100, or 133.
This lack of PCI-X slots on Athlon64 motherboards (you have to get a dual opteron board to get them) means i may have to go Intel for my next systems, and i was really hoping to get an Athlon64 because Lightwave runs best on them overall.

#49 -I heartily DISAGREE with your conclusions. As you will see soon enough DDR2 is at present the same performance as DDR (at best) at twice the price or more. While I do appreciate the potential of DDR2, the current execution is like Prescott - much ado about very little.
As for your bandwidth, we are talking about an Athlon 64 and NOT an Intel CPU. Intel design and deep pipes keep it constantly starved for bandwidth; A64 on the other hand has been shown to perform just about as well with current single-channel DDR as it does with much greater bandwidth dual-channel DDR. This actual performance certainly refutes your claim for the A64 "needing DDR2". Even dual-channel is more a checklist item most consumers demand than it is a huge performance booster on A64. But dual-cahnnel will indeed be a part of socket 939 - doubling memory bandwidth for an Athlon 64 that already competes quite well with single-channel memory.
I do agree with your point about hard-drive throughput, and there is little to complain about in the nF3-250Gb design in that regard.
Talk to memory manufacturers about DDR2. Most are extremely frustrated at having to add huge buffering to even get the 533 stuff to work. In addition latencies are so high at 4-4-4-8 that any performance gain is pretty much nullified. And the cost is prohibitive (sound like early Rambus?). Things WILL improve with time on DDR2, but your sweeping pronouncements are just misinformed.

PCI Express and Hyperthreading won't make a bit of difference in today's games. The only benefit I can think of with nForce3 is *maybe* better sound, and gigabit LAN. PCI Express has been shown to only produce minimal effects on fps, and who cares about hyperthreading unless you enjoy burning CD's and compressing your latest movie while playing a FPS. What this chipset really needed, and the ref . board doesn't support is DDR2. Memory bandwidth and SATA hard drives are the only thing that's going to unleash the power of our already over-kill video cards and load the expansive levels in an acceptable time. Why this article failed to acknowledge this I don't understand.Reflex - Wednesday, March 24, 2004 - link
#46: For purely gaming purposes the Soundstorm does an adequate job. No complaints there. But many people use their PC for more than gaming, and anyone who cares about the actual quality of the sound coming out, especially for music playback would care about the differences. Yes the S/N ratio is very poor on SoundStorm setups. Anyone who cares about excellent reproduction would not be using SPDIF cables as well, they would demand a coax solution for digital output(Turtle Beach SC for instance offers this).Like I said, it was a leap over what was included on motherboards when it was first released, but it has stagnated since then and the competition is far ahead now. Even Creative Labs, which is not even remotely close to being a leader in sound quality, is far beyond the SoundStorm nowadays. Now give me a SS solution with 24/96 capabilities and 106 S/N ratio and they would be back in the hunt. But that won't happen, nVidia is not a audio company.

The dually is good if you're running a game and other apps even if they are single threaded. I don't of course but many do, to switch quickly to avoid the boss or for 10 minutes relaxation while working. There is some loss of performance as a result of the cpus watching each other but with the present design and power of the opteron it wouldnt be noticeable. I'd like a dually.BikeDude - Wednesday, March 24, 2004 - link
#41: Soundstorm=poor quality in what way? S/N? I'm using the SPDIF connector and get 5.1 surround in most of today's games and DVD movies. What other audio solution features Dolby encoding in hardware? I have not seen (heard) one yet.SoundStorm is the only audio solution that offers Audigy2 much competition when it comes to CPU usage in games.
When something better appears, I'll switch in a second, but for now I dread my next motherboard upgrade as it'll mean I'll have to go back to standard audiocables again (and no less than three at that, in addition to the SPDIF cable!). :-(
As for USB2: It sucks. Compare external drive solutions, the old firewire400 interface wins every time. If nVidia has really cut firewire support, lets atleast hope they get USB 2.0 support right this time. I had to install an extra USB 2.0 controller to get my Thrustmaster FF wheel working for more than five minutes at a time (I tried with both Epox 8RDA3+ and ABit AN7 motherboards).

#44:My bro is a BeOS fan too! How fun is that?
iwantedT - Wednesday, March 24, 2004 - link
personally i wouldnt mind a dual cpu a64 solution. In my experience, it means a hell of a lot more time between upgrades. Hell, i've even still got a dual celeron 500 bp6 setup that is quite usable still, even tho its running BeOS, ie. support is kinda dead :)ripdude - Wednesday, March 24, 2004 - link
Good article I must say, though the lack of PCI-Express is a small disappointment.Also, the conclusion states that socket 939 is a couple of months away, is there a bit more certain release date? Perhaps somewhere in april/may?

Trogdor: Yes multi-threading is more complicated, however its a shift that everyone *is* making. There is really very little excuse to make single threaded applications on today's hardware and operating system environments, its an issue more of an established method of doing things giving way *very* slowly to new ways. For an industry that embraces most new technology, its strange that they did not change their design philosophies long ago, really once Win9x(and Pentium CPU's) became a standard the infrastructure was in place...
