At work we got a laptop for £800 with a AMD turion X2 cpu and a pretty rubbish card and he was going on about how good it was, when I said it was pretty rubbish and you may as well get a c2Duo for that money he said that the AMD was better because c2duo in laptops are only 32bit wheras the AMD is 64bit and can be divided into 32bit cpu so it is effectivly quad core, this dont seem right to me so I though id see what you guys thought, is it true?
Work Mate Think AMD Is Better Than C2D for Laptops?

C2D is 64bit.
the blokes an idiot with no idea about computers, its no where near true 
intel c2d laptops are both 32 bit and 64bit depending on generation, the earlier being limited to 32bit due to the chipset while the new santa rosa chipset is 64 bit. The chip itself is 64 bit.
64bit is 64 bit whether there are 1 core or lots of core, dividing 64bit dual core to make 32bit quad core is not possible. You can not change a 64 bit to 32 bit, although current chips allow either 32bit or 64 bit to run on them.
On laptops the intel is a great deal better than the amd chips clock for clock although the turion makes up for it with value for money at the lower end.
Hope all that makes sense.

Yea thanks, so all the C2Duo are essentially 64 bit but some of the older ones have 32bit chipsets. I thought he was talking rubbish so when I see him next i'm gonna say I went on this forum and they said you were and idiot.
BTW can anyone help me on my post in this forum section about my computer crashing / frying?, it is near the top, thanks.

Core Duos had a chipset limitation, i.e. the first Macbooks where 32 bit. But everything Core 2 Duo, barring chipset limitations, is now 64 bit ready.
Even as a rabid AMD fanboy myself, there have been vanishingly few times AMD has had a compelling mobile option. Desktop and server yes, until the C2D! I am not sure where this chap is getting his ideas.

Core Duo didnt have a chipset limitation, it was a 32bit CPU. However Core 2 Duo (merom) is pin compatible with Core Duo, you can swap in a Core 2 Duo 64 bit processor on the large majority of early Core Duo 32bit laptops, and yes, you then have a full 64bit lappy.
Core 2 Duo replaced the early Core Duo very rapidly.
There are no quad core lappys, both Both TurionX2 and Core 2 Duo are 64bit processors which can run 64bit, 32bit, 16bit, or even 8 bit code, without the need for on the fly conversion. (IE they can run all those types natively).

Actually, there are
.Actually, there are
There is? dual socket Meroms? Some Quad AMD, or just a lappy built with Kentsfields and custom motherboard/cooling?
Just spotted Xtreme Notebooks lappy based on the desktop processors.... Released earlier this month fair enough, but its not actually build with mobile tech, must be a power hungry beast hehe.

never said it was
. Desktop processors are used in laptops more often than you'd imagine.Aaaaaand take a breath.
He's wrong, C2D are better however a few months ago Turions were a lot cheaper.

my dad has a laptop which uses a pentium 4 3ghz prescott... even when on a tray, the tray gets warm and whenever anything which puts load on the cpu is done it gets extremely loud, and the battery life is only 90mins-2 hrs.

Oops. Some Intel chipsets i.e. 945PM , even though they were compatible with Core Duos / Core 2 Duos, still could not address 4gb of memory. Yeah you have a 64 bit CPU, but one of the major benefits is lacking.
Reminds me of the old Sinclair QL... *rambles on incoherently 16bit chip - 8 bit bus ... cairo!.....tall as a house*
Most laptops dont have 4gb memory installed anyway... most dont even have 2gb.
Not quite the same as the old QL.. (Not just QL's mind. IBM PC, 8088, 16bit processor 8 bit motherboard/support chips). At least the C2D has a 64bit wide FSB with reasonable bandwidth to the motherboard. And even with less that 4gb, its able to process 64bit calculations in a single clock cycle. So still a proper 64 bit system.
Oh, and btw, According to intel 945PM supports 4GB memory, and so with a 64bit OS installed, you'll get a linear bank of ram, rather than PAE addressing when the machine is equipped with the maximum amount of ram.
Even the majority of desktop chipsets/motherboards only support up to 8GB of ram at the moment (although windows supports a lot more)
I very much doubt that a 4GB limit is a major problem for the vast majority of Laptop users, so I stand by why I said, most Core Duo lappys can be upgraded to C2D without serious chipset limitations.

Effectively a quad core because you can divide 64bit into 32bit? That is a level of stupidity that just blows me away. I'd answer the rest but it has already been dealt with perfectly coherently.
