nForce 500: nForce4 on Steroids?

SLI Performance
The performance pattern continues in our SLI benchmarks with the nForce4 platform slightly outperforming our nForce 500 system in certain benchmarks while finishing right behind in others. The interesting showing is the reversal in the Serious Sam II benchmarks with the nForce4 system showing improvements and a significantly better minimum score.
NVIDIA has stated the nForce 500 series contains optimizations for improved SLI operations, but except for the F.E.A.R. benchmark we are not seeing anything to back these claims up. It could be due to the beta platform and graphics drivers we are utilizing, or perhaps the improvements are only seen at specific resolutions and settings. All SLI board benchmarks are run at 1600x1200 with 4X antialiasing and 8X anisotropic filtering enabled. This resolution requires at least a 20" flat panel monitor, while our standard 1280x1024 benchmarks can be achieved with the more common 19" and 17" flat panels.

I'm a little tired of hearing about so-called "chipset" hardware RAID. The writer of this article constantly made it seem that it was the chipset that was responsible for performing RAID operations on the disks, whereas nothing could be farther from the truth.Yes, the chipset may offload some of the work, but (in the case of RAID 5) the major calculations, like the XOR calculations, are done by the host processor.
According to [L]http://linuxmafia.com/faq/Hardware/sata.html#faker...[/L] and [L]http://spamaps.org/raidtests.php[/L], Linux-based software raid is much faster than so-called fakeraid, since it has been optimised and developed more than the software drivers of the fakeraid chipsets.
Anyway, just pointing out something that gets on my nerves a bit.

I think for most of us who have a nForce 4 ultras and SLIs, it doesn't make sense to upgrade to AM2 motherboards and processors. We'll need new memory too. No performance increase. Just upgrade to a X2 and that should be a good upgrade for those of us who don't have it yet.Powered by AMD - Friday, May 26, 2006 - link
When in the article says:"In fact, the less than stellar write performance of the nForce4 in RAID 5 continues in the "new" chipset"
It does mean that the write performance is good or not?
thanks!

Means just as bad as before, in a nicer manner. :)Gary Key - Saturday, May 27, 2006 - link
Thank you for the perfect reply. ;-) NVIDIA is working on this for the next refresh, their reasoning at this time is they did not want to introduce potential data corruption issues by improving the performance with the current chipset and driver base. It continues to reinforce our belief that although the nF590 SLI is the most feature laden chipset out at this time, the core continues to be nForce4 Plus in our eyes. This is not bad at all, just what can you do with a less than stellar CPU release (still an extremely strong CPU lineup) from a marketing viewpoint. I think NVIDIA and ATI are going to be hamstrung on sales with the AM2 release but hopefully they can make it up when Conroe (Core 2 Duo) launches shortly. :) The bios revisions we have received this week have improved performance but nothing that would make a nf4SLI/4800+ owner want to upgrade yet.

AM2 can just die.afrost - Thursday, May 25, 2006 - link
i'm glad you took the time to type all that out.....KHysiek - Thursday, May 25, 2006 - link
Well, but it does say precisely right about the whole AM2 transition.This is the most pointless hardware upgrade I've seen forfew last years.
The only significant advantage of AM2 is a bit more featured mainboard. And you pay more for less speed. I think AMD is on the way down and no K8L can save them, cause it will be quad core only. What typical user needs quad core for price AMD keeps (like their pricing for current X2 CPU's versus Intel's).
Core 2 is huge leap forward and combined with Intel manufacturing power will make big push back for AMD in coming months.

Gary, what's about that QoS network driver/protocol hanging around in my WinXP for years? I heard it does some quality of service stuff/packet prioritizing/etc soo... is FirstPacket just an interface for this Microsoft QoS thing? Or is nVidia didn't know about it and reinvented the wheel?Gary Key - Wednesday, May 24, 2006 - link
I raised this question at the Editor's conference as it appeared to me they decided to take advantage of some hooks/protocols in XP. I have a meeting with the platform manager tomorrow and hopefully some discussions with the Network guru next week after his return from vacation. I am trying to get an answer before our roundup is published. I noticed some interesting inter-actions during our network testing, will say this, they (NVIDIA) really took the networking side seriously on this release although most of the features are designed for the server/workstation market, but we get them for free on the desktop. We expect further hardware/driver improvements in the next refresh. I am trying to compare the outbound FirstPacket numbers to a D-Link Gamer Lounge at this time along with how both prioritize packets on the outbound lanes. There are so many different tests and options in just the new networking features to run that is a bit overwhelming at this point and of course the new draft-N equipment showed up this week also. ;-)
