Hi all,
At the weekend I nearly bought the Advent 8117 laptop which has a Pentium Dual Core CPU. It's advertised as having the T2080 cpu - which is a 1.70GHz, 533MHz FSB, 1MB Cache. My question is simple enough, what's the difference between this dual core cpu and a core 2 duo cpu which I saw in some other models? I've always been an AMD man myself so I'm not upto speed on intel.
TIA,
Pete
 
The Core 2 Duo is a vastly superior/faster processor. Your'd have to have atleast a 2.6GHz Pentium dual core to match a 1.7GHz Core 2 Duo.
A 1.7GHz Pentium dual core would be slow, i wouldn't bother with it unless on a really tight budget...

the e2140 and e2160 desktop processors are called pentium dual core for marketing reasons. not sure what its like with laptops. the core duo laptop cpus are 32bit, the core 2 duo ones are 64bit and some other changes.
 
The T2080 is a Core 2 Duo CPU. Intel are just reusing the Pentium name for their lower-end C2Ds with only 1MB of L2 cache. It's not quite as fast as a regular C2D but a lot better than the old P4s.
 
Looks like the Low end Pentium T20XX laptop chips are actually Core Duo processors, not Core 2 Duo. If you look at the link a couple of posts up, it shows 64bit support is lacking.

Im guessing intel had a lot of Core Duo stock left over as Core 2 Duo was released very quickly after the Core Duo release.

Ah, OK. I assumed they were C2D because the E2xxx series are C2D. This laptop has an original Core Duo (Yonah) CPU at 1.66Ghz and it's a T2300. The 533Mhz FSB is interesting as my T2300 is 667Mhz. Seems to be a cut down Core Duo.

That might actually make sense though, Core Duo's were still sooooo much faster than P4 lappys (Obviously excluding Pentium-M). Perhaps they wanted to slow down the "Pentium" processor a little more, so it would be more obviously slower than a Core 2 Duo T5 or T7 lappy.

Should still be pretty nippy though, and with laptops, (in my opinion) as long as the computer is fast enough for the software you run, having a faster processor is just shortening the battery life etc.
