Only the AMD Turion 64 has the x64 bits technology. This is a more powerfdul processor than the Pentium M but it takes more power.
So if you do A LOT of multi-tasking, tak e the Core Duo. If you want to keep your laptop the longest possible, take the AMD Tuion 64. The Turion manages well in multi-tasking, but it won't delivers the same performances than the Core Duo.
Personnally, you should take the AMD Turion. Less expensive and ready for the future, this is a wonderful mobile processor.
Which one is better, the Intel Core Duo or AMD Turion 64 ML? Does the Intel Core Duo come in 64 Bit? I was hoping to get a laptop with Intel Core Duo, but I wanted the 64 Bit for when Windows Vista came out. Apparently you can't have the best of both worlds. So which one should I go for?
