Same socket

All AMD Turion processors with MK-xx model numbers require socket S1. The main advantage of that socket over socket 754 is the type of supported on-chip memory controller. The socket S1 supports dual-channel DDR2 SDRAM controller, which can provide more than 3 times of bandwidth of single-channel DDR-SDRAM memory controller supported by socket 754. The frequency of the HyperTransport link for both sockets is the same - 800 MHz.

Good choice instead of Sempron 3400+

Done CPU replacement on my Acer Aspire 7003WSMi laptop. Bit old, but still functional with great 17" display - it simply deserves. Now with this Turion, 4 GB RAM, and OCZ Agility III 120 GB - runs right as I just wish :)
Good choice instead of Sempron 3400+
