Unibody consensus: 32, or 64?

[raymondu999]

I've been hearing and reading in places that the unibody mbp is 32, and not 64 bit. Could someone with technical expertise regarding the actual specs (not just reading off a site or an article), care to elaborate?

EDIT: I'm talking about the nVidia chipset itself. the chip is the new Penryn, and it's Core 2 architecture, and will be 64-bit regardless. The OS, Leopard, will be 64-bit (or partially). But the chipset itself? Kinda like when they had the first C2D MBPs. the chip was merom (64bit) but the chipset was 32bit.

You mean the the OS and system hardware? They have been 64bit since Apple adopted the Core 2 Duo processor.

Sorry, I phrased my question badly. Edited my starter post.

In another thread, we discussed whether it is a 32 or 64-bit chipset, but apparently no one actually knows for sure. All anyone can do is make educated guesses for the time being until someone gets a confirmed answer from Apple or nVidia.

32 bit chipset

quoted from ifixit's tear down of the new MBP

Apple is sticking with 32-bit chipsets for their portables, so you'll be stuck at 4GB RAM forever with this machine.

The thing is I want people who actually understand the internals, in order to debunk what is true and not about that statement.

An official answer from Apple would be even better though.

would the computer be able to support 4 GB+ of ram if the chipset was not 64bit?

 

[raymondu999]

Don't think so. I think that's what we had when Apple released the first c2d mbps
