A Sempron Processor, option to rebuild kernel

We are using a machine with the Following Processor to run *, what is the option in the config should we use, I see Athlon, but is that the best fit?

Model AMD Sempron™ 2400+
Chip MHz 1680.00 MHz
Cache Size 256 KB
System Bogomips 3348.88

Thanks in advance!

Above I was speaking of the kernel config and rebuilding it respectively in regards to the processor… Would Athlon be the correct choice?
