Conroe's true 64-bit processors ?

[curvey]

My question may seem a little odd, but i was told to make sure these processors have true 64-bit achitecture (core or something) - otherwise there just 32-bit processors.

Could someone point me to the right direction ?

I understand they have *EM64T 64-Bit Technology* but thats all it says.

Also, previous LGA775 cpu's are 32-bit ? then how come the Conroe 64-bit cpu's are also socket LGA775 ?

Any help is much appreciate

Cheers.

However Conroe is a totally different design, its 64bit from the ground up, and doesnt need any 'tricks' to work in 64 bit mode. There appears to be little or no performance loss when running in 64 bit mode. The chips are generally more powerfull than AMD64's in both 32bit, and 64bit execution speeds.

Wow thanks for all the feedback, the above quote and others seems to some up the conroe being 64-bit all the way. I originally had s478 (3.4EE) and had to use an intel driver for this to run 64-bit applications - running 2 cycles for a 64-bit instruction.

As for the LGA775 socket, this has supported 64-bit for ages as there have been P4 processors supporting the extensions for quite a while. It was S478 that was 32-bit only.

I was'nt sure about this LGA775 always being a 64-bit socket, i have been living in the past for a long time with my s478.

Just ordered the new conroe - Thanks guys for the information.
