Intel Core i7 870
29 March 2010
Excerpt: Although this Core processor is known as the ‘i7 870' it is based on the Lynnfield core rather than the higher-end and more expensive ‘Bloomfield' core. To distinguish a Bloomfield chip from a Lynnfield model, you'll need to pay special attention to the model numbering; all Bloomfield CPUs feature a 900 series number (such as 920, 940), whereas Lynnfield i7 CPUs use the 800 numbering scheme (860, 870).
Conclusion: The maximum overclocking attained is an astonishing 4.2 GHz (Turbo Mode disabled) with the register at 200 MHz and multiplier at 21 (200×21=4200). However, voltages had to be adjusted so it is not recommended. In end, just go with the clocks the Turbo Mode sets for you dynamically.
Conclusion: The Core i7-870 represents the best Lynnfield currently has to offer. Needless to say, my expectations were quite high. When it comes to performance, though Intel delivered. The i7-870 consistently topped the charts, even outpacing the Core i7-920 in several benchmarks. Without a doubt, this is the Nehalem-level performance Intel promised. As with all of our systems, we also tested the Core i7-870 for stability and construction quality.
Excerpt: This CPU offers superb performance for the price that will excite video editors, rabid gamers, and others looking for top performance. Less-demanding users, though, should consider the much cheaper Core i5.
Pros: Very fast, "self-overclocking" Turbo Boost feature, Supports Hyper-Threading
Cons: Upgrades require new motherboard with LGA 1366 socket and new chipset, Supports dual-channel, not triple-channel, memory architecture
Intel Lynnfield Core i7-870 and Core i5-750 Processor Review
8 September 2009
Excerpt: Intel's latest (and possibly greatest) desktop processor launch is upon us today and with it finally come the answer to questions we, and we assume you as well, have had for months if not years. The processor codenamed Lynnfield has been on our radar since at least the middle of 2008 and has been slowly gaining steam as details of the CPU were revealed. Of course a large majority of the technology in the Lynnfield processor already exists in the current Nehalem-based...
Summary: The new Core i5 is definitely a major step for the user that likes mid-range CPUs. Core i5-750 is going to arrive on the same price range of current mainstream CPUs but with a far higher performance for most applications. This is great news. The not so great news is that you will need a new motherboard to use it, so you won’t be able to upgrade your PC by just replacing the CPU: you will need to replace the motherboard and possible your memory modules as well, if you are...
Excerpt: In my opinion, the new Lynnfield Core i7 processors are a very good step in the right direction. Through testing and benchmarking, when compared to a Nehalem system, the new Intel i7-870 packs a lot of punch for the dollar.
