As much as I know, Dothan (Banias (Pentium-M) 2nd edition) will support Hyperthreading in laptops. As much as I know, it should arrive as a Christmas present ;) It makes me thinking because I want to buy a laptop, and this can be a real boost (which I might not want to miss) for the next few years. > Both claim this laptops doing more box time over normal lithium power > and real time smp behavior > This shit is gonna rock if it works ok , does the latest kernel support > this ? Yes. Hyperthreading works fine in Linux (2.4.x) and it works as if you had two processors. Actually, Linux doesn't mind about it, because it really looks for Linux as if you had two processors. It starts from the BIOS itself (see http://www6.tomshardware.com/cpu/20021114/images/start.gif for example). Intel has released a special compiler which supports compilation using hyperthreading (version 7.0 of their compiler, if I am not mistaken), so you can also use its benefits. I have no idea if gcc supports it, but I believe that v3.2.3 does. > I wounder though what will amd response to this threat be AMD has Opethron. That's a surprise which arrived from another area.
