I've upgraded my 1.83GHz Core Duo to 2.0GHz Merom. I'm still running the 32-bit version of Windows.

On the dual core high definition video encoder and decoder I use, I am seeing a performance increase of 35%.

Personally I would NOT be buying a laptop brand new right now with Merom around the corner.

It sounds like the Core 2 Duo processors for desktops (conroe) are a big improvement on the Pentium D processors but is the core 2 duo for laptops (merom) actually that much better than the previous core duo processors. Apart from being 64 bit i don't really see much difference. Wikipedia says there is a 20% increase in performance and that doesnt sound that major to me.

20% is quite a decent amount. The slowest Merom with 4MB cache, the T7200, runs at 2.0Ghz and should cost as much as the Yonah T2500 (also 2.0Ghz). With a 20% performance gain, the T7200 should perform like a Yonah at 2.4Ghz. The fastest available Yonah is the T2700, at 2.33Ghz.

Essentially, the 'low-end' Core2 Duo will outperform the top-end Core Duo (and probably draw less power too, and it'll definitely cost less).

Lots of people have decided that it's worthwhile to upgrade from a T2300E to a T2400 - and that's only a 10% gain in clock speed. Actual performance gain would be more like 5%, and you're paying a fair bit extra for that (quite apart from the fact that the T2300E draws about half as much power as the T2400). If that sort of thing is worthwhile (paying extra for a hotter CPU which gives 5% better performance), would think that buying a Merom is definitely worthwhile.

Merom over Yonah

+20-25% processing improvement
Same or lower power useage
Even more efficient use of memory, lowering latency and boosting throughput
64 bit instruction capable



Merom details

Available in late August, probably in quantity 1-2 weeks after that, with OEM's likely having them at launch

speeds 1.86-2.33ghz

In most cases should plug into current Core Duo laptop sockets. Some laptops may require a new bios. Many tested using engineering samples have not needed any change at all.



Can't think of the rest atm.

Yeah, I just talked to Dell and the rep I talked to had no clue about the Merom...I was calling about the M1210. It sounds like an awsome chip..I am just curious as to how long it will take Dell to pick them up and start using them in their machines...I hope they are not alienware and keep using outdated crap in their laptops and still charge premium prices..

@agentofthenorth: how does this reimburstment work?

The Core 2 Duo boasts an all-around 40 percent improvement in speed and power efficiency. In notebooks, they are said to perform 20 percent faster with the same power usage. In desktops, they are said to perform 40 percent faster with 40 percent less power and in servers they are said to perform 80 percent faster with 35 percent less power.

Notebooks using the nw "Merom" mobile Core 2 Duo chips will ship in late August, Dell said.
PC Magazine


My question is, will the Core 2 Duo chips be introduced to the existing model lines or will there be new models for the Core 2 Duo lineup? The Core 2 Duo desktops are already available on Dells web site. I'm in a holding pattern right now waiting for Dell to release the Core 2 Duo notebooks.

I wanna get my hands on a M1710 ASAP and I just wish there was a definitve date as to when Dell will put the Merom in their laptops. I read anything from late August (very optimistic) to late November.
