core 2 duo equivalent of athlon 64??

gLaCiuS * · 24th March 2007, 8:04 PM

hey I'm looking at getting a laptop thats at least as fast or faster than my current desktop

What I have now is an AMD Athlon 64 3200+ (2ghz)... does anyone know what equivalent C2D CPU would be equivalent to this? eg. the 1.66 or 1.83 with 2mb cache or the 2.0ghz with 4mb cache? Or around how much faster would it be?

Thanks

I'd safely say that any Core 2 Duo would be substantially quicker than a 2Ghz A64.

I would say you are correct.

A 2.4ghz dual core A64 would challenge a 1.86ghz C2D, but no single core a64 will compare to a core 2 duo.

I would imagine that a C2D L7200 (1.33Ghz) would be slightly slower in single-task applications than the A64 - but it'd still be quicker for anything which can use both cores.

Any standard-voltage Merom would beat the A64, from a small amount to a very large amount depending on the task.

Great thanks, thats what I was hoping

One last thing, I have a choice between a Core Duo 2.0ghz (not core 2 duo) and a Core 2 Duo 1.66ghz for the equivalent price (or 1.83 c2d for $300 more), I'm assuming the difference between these would be roughly equal since they all have 2MB cache only?

I would get a C2D, since I'm pretty sure Core Duo's are 32bit cpu's. And C2D's are faster clock for clock.

www.notebookcheck.com has a few benchies, read an article there about merom (C2D) vs yonah (CD), iirc they concluded merom was about 10% faster clock-for-clock based on synthetic benchies, but I reckon that understates it, and the diff will only grow into the future.

Generally speaking, if price is not a consideration (which it isn't really in merom vs yonah low-end) go for the later tech. And yep, C2D=64bit, CD=32bit.

Don't get a T5600 for $300 more than a T5500, not only is it a ripoff (staticice the prices for those processors, you're prob. paying for a tech to open the lappy up and swap the CPUs) but you'd barely notice the difference. Much better off to spend $300 on getting 2Gb RAM, esp. if running Vista or gaming (and then especially so if your lappy is coming with a turbocache/hypermemory GPU)

My C2D T5500 (1.66 GHz) does 1M Super Pi in about 34 seconds. My A64 3200+ (2.0 GHz) does it in about 45 seconds.

Synthetic, yes, but it shows that the C2D easily eclipses the A64.

Awesome, and yep its a turbocache one so will definitely spend the extra on 2GB ram instead

Thanks a lot for the help everyone!, love u all
