Socket 939 was introduced by AMD as an answer to Intel's new platform for desktop products, Socket LGA775. Although it does not support DDR2 memory, the combination of various Socket 939 motherboards and Athlon 64/Athlon 64 FX CPUs has been repeatedly shown to either match or outstrip Intel's offerings in performance per dollar ratios when it comes to content creation and gaming. In business applications and multimedia, Intel continues to hold a slight advantage.
