Mobile CPU Wars: Core 2 Duo vs. Core Duo

Application Performance using PC WorldBench 5
Looking at older application performance, the Core 2 Duo advantage shrinks to 5.5% at the same clock speed. The performance difference here is not enough to justify an upgrade if you're a Core Duo owner, but for a first time buyer if prices are the same, the Core 2 Duo is simply the right choice.

I know that we are perhaps past the time for this, but I'd be curious how the Pentium M stacked up against its replacement, the Core Solo. It might shed some light on the roots for the Core line of processors.ksherman - Thursday, August 3, 2006 - link
I for one hope Apple pops these babies in the MacBook as well as the MacBook Pro. I have been reading a lot of rumors suggesting that Apple will only put Merom in the Pro model at first... Seems kinda goofy, since they purchase processors in *relatively* low quantity. Ive got my eye on the MacBook, so any performance increase with no price premium is always a plus, and I do plan on doing a lot of video editing/renderingmlittl3 - Thursday, August 3, 2006 - link
I'm waiting for the third revision of the Macbook Pro in the middle of next year. By this revision most of the problems with the new designs should be ironed out and these notebooks will probably be based on the Santa Rosa platform (800 MHz FSB). Right now I have a 1.5 GHz G4 Powerbook and it does what I need. I will upgrade to the Macbook Pro 2.4 GHz Core 2 Duo (Merom) on the Santa Rosa platform. If you like your notebook right now, I would wait until then. This would give you the most stability and bump in performance in the near future. Expect the third revision sometime next summer.mlittl3 - Thursday, August 3, 2006 - link
To be more clear:First Revision - Macbook Pro 2.16 GHz Core Duo 667 MHz FSB 2 MB (1Q 2006)
Second Revision - Macbook Pro 2.33 GHz Core 2 Duo 667 MHz FSB 4 MB (3Q 2006?)
Third Revision - Macbook Pro 2.4 GHz Core 2 Duo 800 MHz FST 4 MB (2Q 2007?)

Santa Rosa... At the earliest? I mean, I supose with the Core 2 Duo being 'crippled' by a slow(er) FSB, it might be worth the wait. But what do you think Anand means by, at the earliest?Whats next after Santa Rosa? Does he know something we don't know? Well, thats a given, but now I'm sketched out about all this... Should we expect some early adopter problems with the introduction of this newfangled Robson technology? God, for a hardware enthusiast, who would've thought that making a new hardware purchase could be so tough. All I want is the fastest performing Merom/Leopard based Macbook Pro available. Am I really going to have to wait until at least Santa Rosa next year? It's going to be a long wait...

What three Compaqs?

Didn't you see the three compaqs in the review? ;)Take care,

now this is a test i can totally appreciate: everything is identical except the CPU, so you get to see what the REAL WORLD benefit of changing the CPU is in your REAL WORLD system that people might actually buy/own. ie, instead of maxing everything else out with parts 99% of people don't buy / can't afford.of course the result is that you see that the real world difference is only noticeable in some situations and with some programs. but hey, that's the reality of it and actually it's easy to see that since the pricing is comparable and all else the same, it's a decent upgrade and certainly a level of future-proofing as well.

It was interesting to compare the numbers in this review with the previous Core 2 Duo desktop review where 2MB vs 4MB L2 cache was examined (although at 1,83GHz/1066)http://www.anandtech.com/cpuchipsets/showdoc.aspx?...">http://www.anandtech.com/cpuchipsets/showdoc.aspx?...
Its not a perfect comparison but from what I can gather, there are significant improvements performance wise coming from the core, even in the non-FP/SSE related benchmarks. A favorite argument among some people is that the extra cache makes all the difference, I hope this will shut them up! (tho I really doubt it)

In SSE code, I see close to a factor of 2 performance increase from Yonah to Merom much of the time. These benchmarks are depressing. The improvement should be better than what we see. Does no one vectorize?
