Athlon X4 840 compatibility review

Overall, the AMD Athlon X4 840 has very good performance. Its 4 cores clocked at 3.4 GHz provide extremely swift processing speeds and allow multiple 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The CPU is now over 6 years old, which means it is extremely out of date and is based on very aged technologies.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 AMD.

Created with lithographic technology sized at 28 nanometers, the Athlon X4 840 is built for extreme speeds and efficiency, and with a Thermal Design Power of 95W the amount of power necessary to run is not excessive.
