New nForce Boards Previewed

s3k writes "Firingsquad.com takes a look at nVidia's new nForce4 chip. It now includes a hardware-based firewall for improved CPU utilization, support for Serial ATA 3 Gigabytes/second hard drives, Gigabit Ethernet, and most importantly, 20-lane PCI Express. Firingsquad includes game performance numbers with nForce4 Ultra and a few performance notes on nForce4 SLI, which, according to nVidia will need a 550-watt power supply!" pacmanfan adds a link to PC Perspective's article (including benchmarks), Necroman points out the coverage at Bjorn3d and Anandtech, and Atif Butt would like you to check ATIF Approved for their take. The same boards, the same NDA -- don't be surprised to find the reviews cover similar ground, and are mostly positive.

  1. Mmm. Goodies. by Space+cowboy · · Score: 4, Interesting


    I *do* like the trend for passing computationally-expensive chores onto support chips rather than the CPU (ethernet checksums, firewalls, raid checksums etc.) but what I would really like is a raid-5 facility on-board.

    If you look at a 3ware 9500 card, it'll cost ~£500 for an 8-port setup! Given that the N-force can support 8 drives (4 sata, 4 ata) in a single RAID image, it would have been nice to get the raid-5 as well as the -1 or -0 levels. You'd be insane to risk losing 1-2TB of disk (assuming 4-8 250GB disks) on a raid-0 array!

    I know I can run software RAID across the disks, but I'm still more comfortable with h/w solutions - I've tried s/w raid (and it has failed, bigtime) in the past, and getting past the psychological barrier to try it again is hard - losing oodles of data is a huge body blow, and when you have that enormous amount of data, even restoring from originals is a pain :-(

    All I want is a single server with enough space and reliability to store all my DVD's and MP3's of CD's, is this too much to ask ? [grin]

    Nevertheless, I'm pretty impressed with a stateful firewall implemented in hardware :-)

    Simon.

      Once again, a slashdotter forgets that he does not represent Joe User at which a product is targetted.

      If you want RAID-5, then go buy your favorite PCI-Express RAID card and do it yourself. There is no since in making this more expensive for the 99.999% that won't be using it.

      It's only a matter of time until drives come with a gig of cache.

      A gig of cache does't make any sense, unless you have a 100TB drive or something. Above a certain amount of cache (depending on the size of the memory that it caches), doubling the cache size only improves the cache hit/miss ratio by a single percent or so. I once knew the calculations that give the hit-miss ratio, but I forgot them. Anyways, it's just standard theory so you should be able to google it up.

  3. Devil's advocate..... by BobSutan · · Score: 4, Interesting
    I just read the preview at HardOCP and they did bring up a good point.
    "The nForce4 is really little more than an nForce3, but with a much deeper feature set. Of course SLI will likely be the big selling point this year...hopefully. I say "hopefully," because thinking back on the nForce3 Ultra launch, we saw many moons between the nForce3 reference board and actual retail samples from motherboard makers. Not to belittle all of the progress that has made it into the new nForce4 feature sets, but I have a feeling that those goodies will not be selling many nForce4 retail motherboards, at least not this year."
    There you go. When will they be available, and how big of an impact is SLI going to be in the coming months for gamers? However, when you think about it the NF4 is being sold to gamers in general and only a small percentage will be able to afford the dual 6800s to populate these boards like they were in tended, in SLI. Looking back at 3dfx's version of SLI and how few of the folks in the communitiy actually used it, I fear this will just be a rehash of a good idea that is prohibitively expensive for most. If this turns out to be the case, NVidia could have just wasted a lot of money on a useless feature. And if that is true, lets hope they've got better monetary reserves that 3dfx did. Then again I don't think that'll be a problem for NVidia.

      The best way to cure this, I find, is to go and buy one. Not emulate, actually go and fetch the hardware you're reminiscing about from eBay.

      I have a 48k Spectrum, a C64, then some newer and still vaguely useful machines like an Atari ST (dedicated MIDI box) and an SE/30. Try actually using them for real, and you'll soon go scurrying back to your platform-de-jour remembering how hard it was to make these things do anything useful.

      Of course, it was fun and might still be fun, but on the whole the computing past is nice to visit but you wouldn't want to live there.

    support for Serial ATA 3 Gigabytes/second hard drives

    It's Serial ATA II which is 3 Gigabits/second. That's just the interface speed, I doubt we'll be seeing drives that fast on the desktop in the near future.

    1. Re:Story Typo by pjrc · · Score: 5, Informative
      To make things even more confusing, the Serial ATA II Specification actually is about adding a bunch of features, not the increase in speed from 1.5 to 3.0 Gb/s.

      These features include as backplane support with higher voltages (FR4 fiberglass insulation of circuit boards is more lossy at GHz bitrates than plastic used in the cables), port multipliers (connecting several drives), port selector (redundant communication channels), native command queuing and other features mostly targeted at the high end server market.

      The 3 Gb/s (gigabits/sec) speed was actually part of the original 1.0a spec. The speeds 1.5 Gb/s, 3.0 Gb/s and 6.0 Gb/s are refered to as "Gen 1, Gen 2 and Gen 3".

      So it's natural to confuse "Gen 2" as mentioned in the 1.0a spec with the revision "II" spec which actually adds features and not increased speed.

    While this comment is rated funny, I would like to know how feasible it would be to actually use a high end CPU & mobo to heat a reasonable amount of water.

    Processors tend to start overheating at around 60-70C (a guess), whereas water from a central heating boiler apparently runs at around 82C. To get any real heating done, you'd have to run the processor at a rather high temperature, and one which would likely badly damage sooner or later.

    Plus, there's the issue of power output - a modern processor might kick out around 70 watts of heat, whereas a typical electric shower is around 5 kilowatts. You might get a slight trickle of warm water from your processor, but nothing much.

    Personally, I wish manufacturers would pay more attention to power consumption of computers, as all that heat still has to be dissipated, even if it's not going to be an effective heater. I'd rather not have my PC whirring like a helicopter just to do some web browsing...

    If the computer industry does not get it's act together with high power usage they will begin to see a decline in these power systems sales. Running 450 watt systems can cost hundreds of dollars a year in extra costs in electricity. For this reason me and the wife are now looking into Mac solutions for standard work stuff and SFF pc's with 200 watt PS's to cut down on the electric bills. In fact it's just not the wattage pull you have to worry about. These systems are now putting off so much heat it puts strain on your home AC systems having to recool off the house as the heat spreads.

      Now, just because a PSU can put out 550 Watts, and just because a system needs a PSU that can put out 550 Watts, does not mean that a system is constantly drawing 550 Watts. A computer's energy consumption is variable depending on what you're asking the system to do at the time. If you're expecting to play DOOM 3, while encoding and burning DVDs 24/7 then maybe you'll max out the power and you will end up paying for that full 550W. Otherwise, there'll probably be long periods of time where the system is sitting idle or doing relatively light tasks and not drawing much power at all.
      Running a computer with a 550W PSU is not the same as constantly running a 550W lightbulb.
