All Sempron Models | Hardware Secrets

Sempron processors based on socket 754 are in fact Athlon 64 processors with less L2 memory cache and without the 64-bit extensions. However, Sempron models launched recently are coming with 64-bit technology support.

The main features of Sempron processors based on socket 754 include:

64 KB instruction L1 memory cache and 64 KB data L1 memory cache
128 KB or 256 KB L2 memory cache
HyperTransport bus running at 800 MHz (3.2 GB/s). This clock may also be referred as “1,600 MHz”.
DDR single channel memory configuration.
SSE3 instruction set on models that have the 64-bit extensions enabled.
90 nm manufacturing process.

On the table below we list all Sempron socket 754 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.
