Lower Prices and New Multi-Cores

Intel introduces 333 MHz FSB multi-cores and first Extreme Mobile processor

July 16, 2007 - Today, together with a price cut for existing processors, Intel introduced two new Quad-Core and four Dual-Core CPUs. Two of those are Extreme processors, coming with an unlocked multiplier. And one of these, the X7800, is the first ever Extreme processor for mobile usage, aimed at hardcore gamers, artists, and media enthusiasts.

Laptops are the fastest-growing computing market segment, and there is increasing demand from those who crave the ultimate in video, gaming and design computing performance, yet want the freedom and flexibility that a laptop brings, said Mooly Eden, Intel vice president and general manager, Mobile Platforms Group.

According to Legit Reviews and Hot Hardware, unlike its Extreme desktop cousins, the X7800 supports the C4 and DC4 (Enhanced Deep Sleep, DeepC4: L2 cache disabled) power saving modes. This should help to keep the dissipation down. Intel said it expects to announce battery-friendly Quad-Core processors for laptop computers next year. However, whether the combination of laptops and high-performance processors is a viable one, is yet to be seen.

Desktop processors

The QX6850 brings us both speed and cores. Running at 3.0 GHz on a 333/1333 MHz Front-Side Bus (FSB), it is faster than the current top model, the Core 2 Quad Extreme QX6800 CPU that runs at 2.93 GHz on a 266/1066 MHz FSB. Just like its two cousins, the new processor has four cores, and a total of 8 Mbyte L2 cache in a two-by-two configuration. On top of that, the multiplier is unlocked, making this processor the ultimate toy for tweakers.

All new desktop processors support Intel's Dynamic Acceleration Technology (DAT). It allows the CPU to run at a higher frequency than its marked, guaranteed clock speed, but within the chip's heat-emission limits. That is achieved by only overclocking one core when the other is operating on reduced power, ensuring the higher consumption of core one is compensated by the reduced consumption of core two.

The E6850, E6750, and E6550, just like the QX6850, are all running a 333/1333 MHz Front-Side Bus (FSB), supported by Intel's new Bearlake chipsets. Trusted Execution Technology (TXT, LaGrande), Intel's hardware-based security/DRM foundation, is part of all new processors.
