FIRST LOOK: Gigabyte K8NXP-SLI

Test Setup
The review of the nVidia SLI reference board did a thorough job of comparing performance of single and dual video cards in standard and SLI configurations. For an in-depth look at SLI, you should start with that review.The goal in this First Look is to first compare performance of the K8NXP-SLI as a motherboard to the top Athlon 64 boards that we have tested. For that reason, we have included performance benchmarks of the nVidia nForce4 Reference board running the same FX55. We also verified performance of the K8NXP-SLI compared to the K8NXP-9. Since they are based on the same design, it is not surprising that base performance with a single nVidia 6800 Ultra were virtually identical between the 2 boards. The same results are therefore reported for both boards running a single 6800 Ultra.
To evaluate SLI performance, we also tested performance of two additional video cards in both single and dual GPU configurations. This included the nVidia Reference GeForce 6800 GT and the Gigabyte 6600GT. In all Athlon 64 benchmarks, the CPU was an AMD FX55 and memory was 2-2-2-10 DDR memory by OCZ. We have no problems in any configuration running the OCZ memory at 2-2-2-10 timings on the K8NXP-SLI.
For reference, test results were also included for the Abit Fatality 925XE 1066FSB running a 3.46EE CPU and an Intel 925X with the 560 3.6GHz 800FSB CPU. All benchmarks on all Reference platforms were run with the PCI Express nVidia 6800 Ultra.

Since the review of the nVidia SLI had found that the biggest advantage for SLI were higher resolutions with "eye-candy" turned on, we ran both our standard 1024x768 resolution for benchmarks, plus the same benchmarks at 1280x1024 with features like Anti-Aliasing and Anisotropic Filtering at their highest levels wherever that option was conveniently available. The same set of DX9 and DX8.1/Open GL benchmarks were run at both resolutions with both single and dual 6600GT and 6800GT.
To clarify test results, benchmarks are reported in separate graphs for standard results at 1024x768 resolution and enhanced results at 1280x1024. Since 1600x1200 normally requires a 20" or larger flat panel monitor, we did not report 1600x1200 results, since most readers will not run at that resolution. For a complete evaluation of 1600x1200 SLI performance, please refer to the nVidia SLI launch review.

With an SLI setup, you may as well test the higher resolutions on the 6600 GT SLI, or 6800 Vanilla SLI it may make sense to limit yourself to 1280x1024, however with the 6800 GT SLI and 6800 Ultra SLI setup's costing 800US/1000US respectively, it won't make sense there.I don't think that someone spending that amount of cash is gonna skimp on the displaying device, might as well test on the these:
NEC/Mitsubishi FP 2141SB
http://www.newegg.com/app/ViewProductDesc.asp?desc...
Viewsonic VP201s
http://www.newegg.com/app/ViewProductDesc.asp?desc...
or that Dell 2001 thing that can do 16x12 @ 16ms as well:
a 600US CRT or a 800US LCD to complement the 800US/1000US video card setup seems reasonable to me, and with these kinds of setup, testing at 16x12, 19x14, 20x15 does make sense, though I believe you can't test it with both AA AND AF enabled at those resolutions as 256MB of VRAM is the limiting factor there.
Also might as well throw in the 850US Athlon FX 55 too :P

#44 YES you can.See it at Toms, 5750 and 6800 or X700 and a X800 or a 6800 and a X800.

I think its the best think you can have!! Better than having 2 cards in SLI, at least for me.

I have received a question for a bit more info on the on the K8NXP boards. We did not receive a complete retail package on the SLI, but the SLI will also include the wireless LAN card.Ports are included on two daughter cards which fits in slots on the computer. The first includes standard and mini Firewire plus 2 USB slots (4 total). The 2nd includes 2 USB slots.

One other thing too.... Nice review Wesley. I have a 21" NEC FP2141sb. I think many other users like myself have CRT monitors. I really just do see the benefit besides space and weight to go to a lcd. I had a 19" dell but it had lag. I had a 17" Viewsonic that had no lag but had a price that was too much for the size of the screen. Eventually I might get a lcd. I remember when the rage was having a video card that would do any game at 1600x1200. Now it seems the emphasis is off of that because of the lcd monitors. I think most still have crt monitors.gplracer - Friday, November 26, 2004 - link
Can you run 2 different varieties of video cards in this board. For example could someone run a 6600 and then later add a 6800 ultra? It is a valid question for many. For example if I were to upgrade to this board I would need a new processor, motherboard, and video card. Some might have to get a cheaper video card than wanted if they had to buy all of this stuff.jcromano - Friday, November 26, 2004 - link
ChineseDemocracyGNR and Googer, thank you both for your answers. I guess the 3Gb/s is mostly just preparing for the future.Jim

Gatak, Last I checked Sony's GDM Line could do such Resolutions. But has been replaced by the Artesian Line.Gatak - Friday, November 26, 2004 - link
A $400+ 19"+ CRT monitor will do 1600x1200 at minimum 85 Hz and can do 2048x1536 at 60Hz. My nvidia card, however, can't seem to do higher than 60Hz at 2048x1536 so I do not know if the monitor can do better than this.In any case, if you benchmark a $800-$1000 SLI setup then you target high-end users and not the standard gray mass... Also, if you benchmark at this resolution then people will see if it works, and if it does, they will want to buy better monitors. therefore the market for better monitors will come and we will get better monitors =)

I ment to say Ultra ATA 33 and putting them on an Ultra DMA (ATA) 100 or 133 controller still makes them run in ATA/33 mode/speed. There is no Improvement for older drives.Googer - Friday, November 26, 2004 - link
EDIT:the truth is that the sata 300 ports would change modes to run in the older 150 mode.
I have some old Ultra ATA drives and putting them on an Ultra DMA (ATA) 100 or 133 still makes them
run in ATA/33 mode/speed. There is no Improvement for older drives.
Jim, Your Hard Drive was not designed from the start to take advantage of newer Technolgical Features.
With all things being the same, no ncq or tcq added and all modes Identical except the added bandwith of sata 3 Gb/s port there would be NO hard drive improvement with your older drive over 1.5 Gb/s. Since the drive you are using was not specified or designed to take advantage of it.
