Pentium D 840 3.2GHz

The Intel Pentium D 840 3.2GHz has 2 cores that run at a clock speed of 3.2GHz.

It has an L2 cache size of 2048KB and an L1 cache size of 32KB.

2.1

Cores	2	More cores means more threads and therefore more processes can be run simultaneously
Speed	3.2GHz	Clock frequency indicates processor speed, but is only reliable in comparisons between CPUs of the same family
Codename	Smithfield	The code name given by the manufacturers
Release Date	26 May 2005	The more recent the release, the more likely the CPU will receive up-to-date manufacturer support
TDP	130W	The 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 Cache	32KB	The 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 Cache	2048KB	After L1 cache, L2 is utilized for slower (but still very fast) data access
Lithography	90nm	The smaller the lithographic technology used, the less power is required to run the CPU, and the less heat is created during intense use
CPU Socket	LGA 775/ Socket T	The motherboard socket and CPU socket should match to indicate the CPU is compatible with the motherboard and will fit into it
Unlocked Multiplier	no	An unlocked clock multiplier means you can adjust the multiplier for an overclocking speed boost

Pentium D 840 3.2GHz compatibility review

Overall, the Intel Pentium D 840 3.2GHz has poor performance. Its 2 cores clocked at 3.2 GHz provide swift processing speeds but allow few processes to be run simultaneously.

The CPU is now over 11 years old, which means it is extremely out of date and is based on very aged technologies.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 90 nanometers, the Pentium D 840 3.2GHz is not efficient at all by modern standards, and with a Thermal Design Power of 130W, the poor efficiency of its physical build is matched by the large amount of power that is necessary to run it.
