For Lynnfield, therefore, Intel has replaced the triple-channel memory controller with a dual-channel item and dumped QPI in favour of the simpler but slower DMI interface. Intels reasoning is that this shouldnt unduly impact on performance because a single-socket desktop chip is less bandwidth hungry than its multi-socket server and workstation cousins. Its a nice theory, but somewhat undermined by the monster 400 price tag attached to this particular Lynnfield chip. Thats the high-speed interface used for peripherals such as graphics cards. The immediate effect is that motherboard chipsets supporting Lynnfield no longer require a northbridge chip. On the downside, it puts an absolute limit on the number of PCI Express lanes. With just 16 lanes, Lynnfield is limited to a maximum of two graphics cards. Strictly speaking, however, its a limitation for really high end rigs. ![]() In fact, the loss of a little bandwidth has done absolutely nothing to slow it down. On the contrary, thanks to a more aggressive implementation of Intels Turbo Boost technology, its every bit as quick as its equivalently-priced Bloomfield Core i7 sibling, the 950. It also helps that Core i7 variants of Lynnfield boast HyperThreading technology, unlike the cheaper Core i5 variant. Clock for clock, HyperThreading delivers a performance boost of approximately 20 per cent in heavily multi-threaded applications such as video encoding and media editing. Its worth bearing in mind however, that HyperThreading is typically of little if any benefit in games. Courtesy of nothing more exotic than a air cooler and using standard operating voltages, our review sample is currently humming a 4.33GHz tune. At that speed its utterly untouchable. Whether its coding video at astonishing frame rates or rendering multiple HD movies at the same time, theres little this chip cant handle. Even Intels uber-expensive 1,000 Core i7 975 Extreme Edition does no more than match it when overclocked. Intel will also sell you the new Core i7 860. Its a 2.8GHz CPU and offers quite literally 95 per cent of the performance for half the price. Its a much, much more sensible starting point for a high performance PC.
