Besides Turion 64 and Athlon 64 Mobile, AMD also has launched Sempron models targeted to the mobile market, which are based on the socket AM2 version of Sempron.

The main specifications for Sempron processors targeted to laptops include:

• Socket S1 (the same socket used by Turion 64 X2) 
• 64 KB instruction L1 memory cache and 64 KB data L1 memory cache
• 256 KB or 512 KB L2 memory cache
• HyperTransport bus running at 800 MHz (3.2 GB/s). This clock may also be referred as ”1,600 MHz“.
• Memory controller supporting DDR2-400, DDR2-533 and DDR2-667 memories under dual channel configuration, meaning that the CPU accesses the memory 128 bits per time, if two or four memory modules are used.
• SSE3 instruction set.
• 64-bit instructions.
• 90 nm or 65 nm manufacturing process.
• PowerNow technology.
• Enhanced Virus Protection technology.

In the table below we list all Sempron socket S1 models released to date. TDP stands for Thermal Design Power and indicates the CPU maximum thermal dissipation, i.e. the CPU cooler must be able to dissipate at least this amount of heat.
