Just release a few days ago. Merom is the Intel codename, the official name is Core2Duo. The CoreDuo (without the "2") was released somewhere beginning this year.
The main difference is that Core2Duo is a 64bit processor, as where the CoreDuo is 32bit.
You might also have heard the name "Conroe": that's the Desktop counterpart.

Hmm, so the Dell XPS only have a 32bits CPU now? Damn, then i don´t order my XPS now. Will wait for the 64 then

BTW, my first post here and hope my English are not bad enought to kill someone. =)

It's not really the "main" difference. The biggest difference is that the Core2 Duo* is significantly faster yet is more energy efficient than the Yonah (Core Duo) and Dothan/Banias/etc (Pentium M) processors.

The 64-bit capabilities (intel calls it "EM64T", but it's essentially a copy of AMD64) shouldn't influence your buying decision, since they:
  • require a 64-bit OS (Win2k3 Server x64, Vista, Linux, etc)
  • show little performance gain, especially for games
  • often even run slower in 64-bit mode, since some drivers aren't optimized for 64-bit yet (especially graphics)

EM64T is nice, since it helps future-proof the system and might help later down the road once Vista is released. But 64-bit is little more than a bullet point on a list of marketed features- it's just 64-bit extensions to registers and allows native 64-bit addressing (in short, more ram).

So the real reason to wait for Merom would be for the performance.

*Merom is the codename for Conroe's mobile variant, so I don't know if it'll even be called "Core2 Duo" when it's released.

Yes, it will be called Core 2 Duo.

When I watched people mess around with Half Life 2 on the notebook Core 2 Duo part, it's pretty much just as ridiculously fast as when I saw it on the Core 2 Extreme desktop part. Then again, it was only a brief look, and I don't think HL2 is really straining those systems.

does the Merom have Hyper threading?? Or do they keep that off all the mobile chips?

^^^ Hyper-Threading has been made redundant in recent times because of the fact these are dual core chips...

Your English is better than our Swedish.
