All Sempron Models

Socket AM3 Sempron

Like socket AM2 versions, AM3 Sempron CPU is compatible with dual channel memory architecture, doubling the memory transfer rate as long as you use an even number of memory modules on your computer. Socket AM2 and AM2+ CPUs work only with DDR2 memories, but socket AM3 processors can work with both DDR2 and DDR3 memories, depending on which kind of motherboard you install them (socket AM2+ or socket AM3, respectively). This way these processors are also compatible with socket AM2+ motherboards and even with some socket AM2 ones.

Socket AM3 Sempron main features are:

• 64 KB L1 instruction cache and 64 KB L1 data cache.
• 1 MB L2 memory cache.
• One processing core.
• HyperTransport bus running at 2 GHz MHz (8 GB/s). This clock may also be referred as “4,000 MHz.”
• Memory controller supporting DDR2 memories when installed on socket AM2+ motherboards or DDR3 when installed on socket AM3 boards.
• SSE4a instruction set.
• 64-bit instructions.
• 45 nm manufacturing process.

In the table below we list the only Sempron socket AM3 model 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.
