NVIDIA’s design team has endowed the nForce4 with four Serial ATA ports and two channels of ATA/133 storage connectivity, for total of eight possible connected devices. In a dual-card config, eight lanes go to each of two physical PCI-E X16 slots.) We’ll have more to say about SLI in a separate article shortly.Īdvanced storage options - In terms of feature set, the nForce4’s storage options are the class of the industry, rivaled only by Intel’s. (In a single-card config, 16 lanes go to a single PCI-E X16 slot. NVIDIA has worked with motherboard manufacturers to make SLI mobos happen, even pioneering a trick PCI-E connector card that will redirect PCI-E lanes as needed. Whatever the technical merits of that claim, it is true that the first Athlon 64 motherboards with dual graphics slots will definitely be based on the nForce4 chipset. However, NVIDIA claims the nForce4 is specially optimized for SLI. Truth is, SLI relies on PCI Express in order to work properly, and any decent PCI-E chipset ought to be able to handle SLI. I’ve listed this capability as a separate bullet point because I’m being generous. SLI support - The most exciting application for the nForce4’s PCI Express lanes is probably NVIDIA’s SLI GPU teaming technology. The nForce4 packs 20 lanes of PCI Express connectivity, sixteen of which will be dedicated to graphics, leaving four lanes for use with PCI-E expansion slots or peripheral chips on the motherboard. PCI Express - We’ve already covered the basics of PCI Express in our review of the world’s first PCI Express chipsets, the Intel 915G and 925X Express. The nForce4’s single-chip design should virtually eliminate any bottlenecks in chip-to-chip communication between the traditional north and south bridge function blocks.Ī block diagram of the nForce4. All of NVIDIA’s competitors have opted for two-chip configurations that will allow them to swap in new north or south bridge chips independently. Because the Athlon 64 (and AMD’s other K8-class processors, including the Opteron and some Semprons) has its own memory controller onboard, the single-chip approach works here. Let’s have a look at the highlights.Ī single-chip design - Like the nForce3, the nForce4 is a single piece of silicon rather than a “chipset” proper with separate north and south bridge chips. Some of the nForce4’s key features are simply shared with the competition, but others are worthy of note because they’re unique. That’s no simple goal to reach in a field where all of the products generally have to conform to the same basic set of standards at any given time. The folks at NVIDIA have obviously worked hard to position the nForce4 chipset family as a distinctive option in the copycat world of core logic chipsets. The question is, do all of the marketers’ talking points add up to superior performance? We’ve tested these features, including ActiveArmour and SATA command queuing, and we have some answers. The nForce4 packs a number of innovative new features, including the aforementioned PCI Express capability, a firewall-fortified Gigabit Ethernet controller with hardware acceleration, and a robust implementation of the latest Serial ATA spec, including Native Command Queuing for SCSI-like disk I/O performance under heavy loads. We’ve finally gotten our hands on an nForce4 reference motherboard from NVIDIA, and we’ve subjected it to a grueling battery of tests to see how it performs against the competition from VIA, ATI, and even Intel. In between the two, NVIDIA announced its nForce4 lineup but wasn’t able to produce review hardware-until now.

We first got a brief hands-on look at VIA’s K8T890 chipset, and then we did a full review of ATI’s Radeon Xpress 200. T HE RACE TO DELIVER a core logic chipset with PCI Express support for the Athlon 64 has occupied much of our attention over the past few months.
