Intel revs up FSB speeds with Core 2 Duo E6750
NDAs dropped today on Intel's latest dual-core offering, the Core 2 Duo E6750. The CPU is a close cousin to the E6700, clocked at the same 2.66GHz speed but with a faster 1333MHz bus. In fact, it's the company's first desktop with a 1333MHz FSB …
Context & Ripple Effects
The E6750 extends the Core 2 Duo line Intel launched in July 2006, and it does so without touching the clock: at 2.66GHz it matches the existing E6700 exactly, with the 1333MHz front-side bus as the only meaningful difference. It is Intel's first desktop part to ship at that bus speed, which makes it less a speed bump than a platform marker.
The timing lines up with the rest of Intel's June 2007 push — new chipsets previewed at Sean Maloney's Computex Taipei keynote earlier that month — so the faster bus arrives alongside the silicon that can actually run it. Pickup was broad for a mid-range SKU: AnandTech and Techgage both ran previews on NDA day, with AnandTech framing its piece around the blunt question of whether the bus bump translates into real-world gains.
First-order effects
- Desktop buyers choosing between the E6700 and E6750 get identical 2.66GHz cores, so the decision collapses to whether their motherboard supports a 1333MHz FSB — older boards need a chipset swap to use the new part's headroom.
Second-order effects
- Motherboard and chipset vendors gain a fresh segmentation axis: boards can now be tiered by bus support rather than socket alone, pushing a refresh cycle through the desktop platform just as Intel's Computex chipset lineup lands.
Third-order effects
- If Intel keeps raising bus speed while holding clocks flat, performance differentiation migrates from raw GHz to platform bandwidth — a structural shift in how desktop CPUs are marketed and compared, and one AMD must answer on its own interconnect roadmap.
The trend: Desktop processor competition in 2007 is shifting from clock-speed races toward platform-level bandwidth, with front-side bus speeds becoming the new segmentation lever between otherwise identical chips.
