Intel to update LGA1366 line with 2.88GHz Core i7 930

Even though Intel is facing virtually no competition on the high-end processor market, the arrival of its Lynnfield-based Core i7 860 early last month threatened to cannibalize sales at the lower end of the enthusiast LGA1366 spectrum. The chip carries the same $290 price tag as the "Bloomfield" Core i7 920, yet it comes with higher clock speeds and Turbo Boost capabilities, a tighter power envelope, and fits into a cheaper platform.

Thus is not really surprising to hear Intel will be discontinuing the latter. However, rather than leaving a wide hole in its LGA1366 lineup, the chip maker will apparently be replacing it with a higher clocked Core i7 930 processor next quarter. The quad-core, eight thread part will run at 2.88GHz and should cost the same as its Core i7 920 predecessor.

Although still unconfirmed by Intel at this point, the move sounds plausible enough. We have already witnessed the replacement of the 3.20GHz Core i7 Extreme 965 with the 3.33GHz i7 975, as well as the 2.93GHz Core i7 940 with the 3.06GHz Core i7 950 and once again with the Core i7 960 running at 3.2GHz.

Does Turbo Boost Help Or Hurt Core i5/i7's Power Efficiency?

Intel’s new LGA 1156-based processors, namely the Core i5-700- and Core i7-800-series, arrived with a bang. Our launch article by Chris Angelini provides all the key information. But, in short, the new processor delivers increased performance compared to Core 2 Quad. No surprise there. But Intel also claims that power consumption went down significantly, so we decided to tackle this prospect with a closer look.

Core i5, i7: Intel’s new processors for LGA 1156.

The Core i5 Innovation

The new P55 platform and Intel’s Lynnfield processors make a are impressive enough from a performance angle, but I’d like to look at the facts from a different perspective. The platform’s foundation still centers on the Nehalem architecture first seen as Core i7 for LGA 1366 late last year, hence the level of innovation in Lynnfield is less revolutionary and more of an evolution.

Intel is great at tweaking, though. From a technology standpoint, Core i5 incorporates a lot more integration, stepping closer to the inevitable SoC (system-on-chip) future by adding PCI Express onto the die. A more aggressive implementation of Turbo Boost adds extra performance for non-threaded applications. Considering that Intel plans to integrate graphics with Clarkdale in coming months, this step could also be looked at as a necessity. Improved Turbo Boost is another building block for turning dynamic overclocking into a real feature. In reality, though, the large motherboard makers have been offering similar features for a few years already.

I see two main benefits of the new LGA 1156 processors for buyers. First, you have decreased power consumption thanks to the integrated memory controller and PCI Express 2.0 interface. The second benefit is performance. Turbo Boost helps to elevate LGA 1156-based parts to Core i7-900-class performance levels in certain applications. Both benefits became obvious in our article, Intel’s Mainstream Magnum Opus.
