Excerpt: Intel designed its Core i5 655K CPU for system builders interested in producing inexpensive pre-overclocked systems. Intel reckons this is possible since it has given the 655K an unlocked multiplier so high-end (i.e. expensive) motherboards with tweak-friendly BIOSs are not needed for overclocking.
Conclusion: The Core i5 655K performed decently against other CPUs. Thanks to features like Turbo Boost and Hyper-Threading, this sample was able to outperform the Athlon II X3 in nearly all the tests when they were targeted at multi-core solutions.
Conclusion: You could argue that the unlocked multiplier allows for better overclocks on motherboards that can't hit a 200MHz Base Clock (cheap boards, in other words), but whether you overclock via the Base Clock or the CPU multiplier, you'll still have to add extra CPU voltage.

Summary: It's nice to see some unlocked processors coming from Intel again that don't carry the Extreme Edition price tag. The $220 Core i5-655K and $190 Core i5-650 are currently about $30 different between price tags which we feel is well worth the extra cost.
Pros: Unlocked multiplier, Very easy to overclock, Works with both P55 and H55 chipsets, Core i5-655K worth the extra money, Core i7-875K "Best Bang for Buck"
Summary: Like I said, it's good to be king. Intel has calibrated its response to the Phenom II X6 quite carefully, and the result is a clean sweep. At stock clock speeds, the Core i7-875K is a better performer than the Phenom II X6 1090T—just a little bit in multithreaded applications, but quite a lot in...
Intel Core i7-875K and Core i5-655K Unlocked Processor Review

Excerpt: Intel has come a long way in the decade we have been covering them at PC Perspective, as has much of the enthusiast industry. While many of readers may not remember a time without overclocking and days when manufacturers like AMD and Intel and VIA strictly forbade it, that time was actually not too...
Conclusion: Opisywany procesor to układ dwurdzeniowy, ale potrafiący dzięki technologii Hyper Threading symulować pracę dwóch wątków na każdym z rdzeni. Jego nominalny mnożnik to x24, co daje zegar 3,2 GHz.
Pros: Bardzo dobra wydajność, Bardzo podatny na overclocking, Łatwe podkręcanie dzięki odblokowanemu mnożnikowi, Zebranie wielu doskonałych rozwiązań w jednym układzie
Cons: Przeciętny, zintegrowany układ graficzny, Mała liczba linii PCI-Express, Wysoka cena jak na rozwiązanie „budżetowe”
