Thread: Intel Core i5 661

The Intel Core i5 661 is the aboriginal CPU we've apparent of a new alternation based on the new Intel Clarkdale architecture and for demand of a bigger description it lies about appear the top end of the basal bisected of Intel's accepted CPU line-up. In added words, it's affectionate of 'mid-range'.


This dual-core CPU is congenital on Intel's new 32nm accomplishment action and incorporates a cartoon dent on the package, admitting not on the aforementioned die (the cartoon uses a 45nm process). Collectively these new chips will be accessible beneath the Core i5 6xx and Core i3 5xx calculation schemes.


The key aberration amid these two ranges is that the 600s accept Turbo Boost while the 500s do not. Turbo Boost is the adeptness of the CPU to automatically overclock one or added of its cores abased on workload. When enabled, the CPU will consistently try and assignment at its best acceleration which, if all cores are beneath load, will acceptable be its advertence speed. However, if alone some of the cores are beneath load, the bare ones are clocked aback and the added thermal allowance is acclimated to overclock the actual cores consistent in bigger performance.




Clarkdale too assumes advantage of Simultaneous Multi-Threading (SMT), which is the adeptness for every amount of the CPU to run two accoutrement at the aforementioned time appropriately dispatch up multi-threaded operations or multitasking.


Essentially, the CPU appears to the operating arrangement like it has alert as abounding cores as it does but in the accomplishments it's alone optimising the adjustment in which it executes cipher so you end up with a achievement improvement. However, the advance doesn't battling that of two concrete cores.


With commendations the blow of Intel's range, the Clarkdale CPUs can be anticipation of as replacing the Core 2 alternation as the access akin of Intel's line-up, admitting Core 2 and assorted Pentium branded chips are acceptable to be accessible in shops for some time to come. This will leave the Lynnfield ambit (Core i7 8xx and Core i5 7xx) as the mid- to high-end and the Bloomfield (Core i7 9xx) alternation at the top.


All these CPUs are based on Intel's accepted overarching microarchitecture, Nehalem. In case you were wondering, yes, this is all rather ambagious so rather than account the countless attenuate differences amid all these ranges, we've put them in a table, area we achievement aggregate will become clear.
