  • Characteristics


The Intel Pentium 4 521 comes directly from the manufacturer's desktop series. Accordingly, the CPU is especially suitable for conventional computers. There it can be used for a quick repair, but can also represent an alternative in the upgrade. The technical function of the used processor is of course given without restrictions.

To provide the required performance, the Intel Pentium 4 521 has a core with 2.8 GHz clock speed and 1 MB L2 cache. However, the CPU has the Hyper-Threading technique, which allows it to handle up to two threads at the same time. So the processor is suitable for different tasks of everyday life.

The use of the Intel Pentium 4 521 requires a LGA 775 socket on the motherboard. Corresponding information is usually found in the manual for the mainboard or the PC system, if it is an OEM device. Often, you can take over the heat sink directly from the previous CPU, as none is included in the delivery.

The maximum power dissipation of the Pentium 4 processor 521 is 84 watts (TDP). Of course, this is only achieved under full load. Furthermore, the inactivity status attempts to further reduce the energy requirement. The CPU also supports the 64-bit instruction set, and the Execute Disable bit has also been integrated by Intel for increased security.
