Intel’s Core i7 processor, formerly referred to as Bloomfield, has been architecturally dissected one bit at a time for the past two years. Talk about a rollercoaster of anticipation for gaming enthusiasts. Gone is the super-quick L2 cache that helped propel Core 2 processors so far ahead of AMD’s Phenom offerings in a myriad of games. In its place is a much smaller L2, a large L3, a HyperTransport-like processor-to-processor interconnect, an integrated memory controller, and the reemergence of Hyper-Threading. If we didn’t know any better, we’d suggest that Intel is going after a different market entirely.
Ah, but we do know better, and it is. At this fall’s Intel Developer Forum (IDF), Intel representatives gave us our closest look yet of production specs for its upcoming Core i7 lineup, along with preliminary performance numbers. In addition to exceptional results in video editing, media conversion, and professional workstation titles, we also received a healthy dose of reality for what we’d see in testing gaming performance. Quite simply, the Nehalem micro-architecture incorporates a lot of improved technology, which is reflected in the speed-ups seen throughout a cherry-picked benchmark suite. However, it reportedly wouldn’t gain much in the way of gaming—presumably as a result of the tradeoffs made as Intel’s engineers optimized their efforts to retake the enterprise computing space.
It’s A Platform Story Now
Thus, our attention shifted to the X58 platform, Intel’s chipset complementing Core i7 at launch. Initial rumblings were that X58 would extend Intel’s support for CrossFireX—AMD’s multi-card rendering technology—through divisible PCI Express links. A number of existing Intel chipsets already accommodated two or more cards, so it was hardly a surprise that core logic armed with two x16 PCI Express 2.0 links would continue that trend.
Then the rumors started bubbling up that X58 might also work with SLI, just like Intel’s “Skulltrail” does.
First, we were lead to believe the feature would require Nvidia’s nForce 200 companion chip. But then, at its NVISION ’08 show in San Jose, the company made it clear that X58 would support SLI natively—in two- and 3-way configurations. We’ll leave alone discussion of SLI and the supposed hardware requirements that kept it from appearing on non-Nvidia platforms previously. By now, it’s a foregone conclusion that the technology needed to enable SLI isn’t a chipset-specific feature, but rather a matter of licensing. The company shared with us the “updated” requirements for what it’d take to enable SLI, and gave us some idea of the configurations made possible by combining Intel’s X58 and the company’s own nForce 200.
