Intel Core i7-5820K 6-Core 3.3GHz

Cores6More cores means more threads and therefore more processes can be run simultaneously
Speed3.3GHzClock frequency indicates processor speed, but is only reliable in comparisons between CPUs of the same family
CodenameHaswell-EThe code name given by the manufacturers
Release Date29 Aug 2014 The more recent the release, the more likely the CPU will receive up-to-date manufacturer support
TDP140WThe lower the TDP, the less power the CPU requires to run and thus the more efficient it is and the less heat it creates
L1 Cache768KBThe bigger the L1 cache, the more data can be stored for lightning CPU access to priority processes (though a bigger cache means a higher latency
L2 Cache1536KBAfter L1 cache, L2 is utilized for slower (but still very fast) data access
L3 Cache15MBThe L3 cache is the largest CPU cache, but still provides very quick access to data
Lithography22nmThe smaller the lithographic technology used, the less power is required to run the CPU, and the less heat is created during intense use
CPU SocketSocket 2011-3 / R3 / LGA2011-3The motherboard socket and CPU socket should match to indicate the CPU is compatible with the motherboard and will fit into it
Unlocked MultiplieryesAn unlocked clock multiplier means you can adjust the multiplier for an overclocking speed boost

Core i7-5820K 6-Core 3.3GHz compatibility review

Overall, the Intel Core i7-5820K 6-Core 3.3GHz has exceptional performance. Its 6 cores clocked at 3.3 GHz provide extremely swift processing speeds and allow many processes to be run simultaneously.

The CPU is now over 6 years old, which means it is extremely out of date and is based on very aged technologies. This processor will be dwarfed in performance by its modern counterparts, and will likely have very little support from Intel.

Created with lithographic technology sized at 22 nanometers, the Core i7-5820K 6-Core 3.3GHz is built for extreme speeds and efficiency, although with a Thermal Design Power of 140W it requires a large amount of power to run.
