Closer Look at Core i7-875K and Core i5-655K Specifications
In terms of their formal specifications, these new overclocker processors can’t boast any features that would distinguish them remarkably from their fellow CPUs. Clock frequencies, number of computational cores, cache-memory size, brand name technologies, thermal design power – everything is exactly the same as by the well-familiar Core i7-870 and Core i5-650.
It is also hard to notice any differences from the existing models even in the screenshots from diagnostic utilities. For example, in CPU-Z the new processors stand out only due to an identification line with a name in it:
Note that Core i7-875K is based on B1 processor stepping, while Core i5-655K – on C2 processor stepping. It means that these CPUs use the same semiconductor die versions as the common mainstream processor models. Therefore, new overclocker processors will hardly be able to offer their owners any special frequency potential, and their only distinguishing feature is an unlocked clock frequency multiplier.
Nevertheless, Core i7-875K and Core i5-655K are special. They do not replace any solutions but add to the existing LGA1156 processor lineup. To stress this idea Intel will ship new processors in special packaging with highlighted “unlocked” word in the name.
By the way, overclocker processors will come without the traditional boxed cooler. Intel was absolutely right to believe that those enthusiasts who go for a CPU with an unlocked clock multiplier would definitely prefer to pick a cooling system themselves.
Intel officials promise that new processors won’t have any compatibility issue with any of the existing mainboards. This isn’t surprising at all, as there is actually nothing really new about them. However, in order to get full access to the multiplier adjustment options, it would be best to update the mainboard BIOS first.
