Conclusion: Intel definitely saw the need to do more to compete with AMD than release a very small amount of Extreme Edition CPUs at the highest $1000+ price point and the release of two new CPUs with unlocked cores for just a little above the retail price of their non-unlocked equivalents is a good start.
Excerpt: Once upon a time, not very long ago in fact, Intel vehemently frowned upon overclocking. There were even times leading up to new processor and chipset releases when it was rumored that Intel would bring an end to overclocking altogether. Thankfully, the rumors of overclocking's death were greatly exaggerated and we enthusiasts continue to practice its black magic to this very day.
Pros: Excellent Overclocking Flexibility, 875K Priced To Move, Strong Performance
Intel Processors with Unlocked Multiplier: Core i7-875K and Core i5-655K Review
27 May 2010
Summary: In a few days Intel is going to expand their overclocking-friendly product line and to offer two new LGA1156 processors with unlocked clock frequency multipliers. The especially intriguing thing about these CPUs is that they won’t belong to Extreme Edition series and their price will be quite affordable.
Excerpt: When it comes to Intel LGA 1156 platforms you have been able to get an awesome mainstream platform since the day it was introduced along with Intel Core i7 800 & i5 700 series ‘Lynnfield’ processors way back in September 2009. Over the past eight months the LGA 1156 platform has sold really well and one of the only complaints that we have heard with the platform from enthusiasts and gamers is that Intel has ignored the overclocker on this platform as they don’t offer any...
Excerpt: Intel's quad-core Core i7 870 is a great all rounder. Short of a six-core monster machine, it's a hard to imagine what can beat it. However, for overclocking enthusiasts it does lack one key feature: an unlocked CPU multiplier.
Conclusion: Frankly, we can definitely thank AMD for the existence of the Core i7-875K. In our eyes, this is Intel's surprising counter to the Phenom II X6 1090T Black Edition . They could have just dropped the price of the i7-870 to $350 and lured away some potential 1090T buyers, but instead they went straight for the enthusiast market and offered the Holy Grail that is freely selectable CPU multipliers. This is a highly unusual, but exciting move on Intel's part.
