Another question:

1st computer: a computer with processor Intel Core Duo Processor L2500 (2M Cache, 1.83 Ghz, 667 MHz FSB)

2nd computer: a computer with processor Intel Pentium D Processor 820 ( 2M cache, 2.80 GHz, 800 MHz FSB)

Both computers have got the same Memory 2GB DDR2 SDRAM


I'm buying a computer for business purpose.

The prices are the same. Which comp should I pick?

Cheers
 
I am not an expert at all, please excuse my dumb question:

I was told that Core 2 duo processors always beat Pentium and dual core processors due to its "architecture" , is that true?

or are you saying Pentium D 820 still beat core 2 duo processors that have lower speed ?

Cheers everybody :)
 
Core 2 CPUs always beat Pentium 4/D processors at same and even higher clock speeds quite easily since the architecture is so much more efficient, yes. However, the CPU you linked (L2500) is not a Core2 but Core based, Core being the predecessor of Core 2. It's still way more efficient than the Pentium D, but it's not quite as efficient as Core2 and the sheer clockspeed advantage (a whole extra 1GHz) plus the faster FSB may give the Pentium D the edge.

However, I would get the L2500 anyway - the L2500 consumes way less power (15W vs 95W TDP), and even where it's slower it won't fall behind too much to be a dealbreaker (if at all - I couldn't find any benchmarks so I can't tell for sure); for business usage I'm almost certain nobody would be even able to tell the difference. The L2500 is, however, a laptop CPU, which confuses me a little - are you picking between a desktop and a laptop? Some OEM desktops do come with laptop CPUs, or did in the past, but those tend to be rare these days.

I'll also point out that the 820 is a 64-bit CPU, while the L2500 isn't - this usually doesn't matter, though, essentially all software is available in 32-bit (actually, a lot of software on Windows only come in 32-bit), but if you know for sure that you need to be able to run 64-bit software you would, of course, have to get the 820.
