Early AMD64 chips (3 to 5 years old) doesn't support SSE3 as x86_64<br>
predates SSE3. You can safely assume that all AM2 socket based chips are<br>
SSE3 enabled.<font color="#888888"></font><br></blockquote><div><font color="#888888"></font><br>I do agree perfectly with you, however, SSE3 capability can definitely be queried by checking the presence of flag pni (Prescott New Instructions) in /proc/cpuinfo.<br>
<br>AMD cores Sledgehammer (steppings C0, CG) and Clawhammer (stepping CG) do not support SSE3 only cores from San Diego (stepping E4) on. ~C</div></div>
