FIRST LOOK: Gigabyte K8NXP-SLIby Wesley Fink on November 24, 2004 9:00 PM EST

Yesterday, we reviewed the first board for nVidia SLI, a Reference board from Asus called the A8N-SLI Deluxe. Asus believed that they had a 30-day lead on competitors with their SLI board, so it will be a surprise to some to see, just one day later, the Gigabyte K8NXP-SLI. Clearly, other Tier 1 motherboard makers have also been very busy!
In addition, Gigabyte also sent Version 1.0 of the K8NXP-9 motherboard. The K8NXP-9 is the same nForce4 motherboard without SLI. The board reviewed last week in FIRST LOOK - nForce4: Gigabyte K8NXP-9 was Revision 0.3, while the 1.0 version is the first production revision. Both of these developments mean that you will be seeing Gigabyte boards based on nForce4 in the next few weeks. You will likely find that you will actually have a choice in SLI motherboards before Christmas - at least between Asus and Gigabyte, and possibly MSI as well.
We were very impressed with the Gigabyte K8NXP-9, and that has been confirmed by Revision 1.0 of the board. We were also able to test overclocking in this go-around, with both the regular PCIe and SLI versions of the boards. Both boards have the same BIOS options and are identical except for the concessions required to provide dual PCIe video slots and support on the K8NXP-SLI. This is very good news for shoppers because it means that you can choose between two excellent Gigabyte nForce4 boards where the only real feature difference is SLI.
While that will make the choice straightforward, the question is what value does SLI, or Scalable Link Interface, brings to nForce 4 and PCI Express. We took a close look at this question in Tuesday's launch article, which is a great place to get answers to this and other questions about SLI performance. Today's First Look at the Gigabyte K8NXP-SLI will take a closer look at the board itself and how it performs in both single and dual GPU configurations. However, we will concentrate on performance comparisons to the best Athlon 64 motherboards that we have tested in the AnandTech labs.
