Question about Merom

post #1 of 21

Thread Starter 
Is Merom anything like Yonah? Is Yonah just a double core version of the Pentium M? I was reading an article about it on AnandTech, and it seems that Yonah has no similarities to Merom. Probably wrong, so you all enlighten me.

Core 2 Duo (Merom) offers %20 more performance over Core Duo (Yonah) with same energy consumption. It also supports EM64T and SSE4 instructions and 4 MB cache.
Second revision of Core 2 Duo will use a new socket and will have 800Mhz FSB.

AnandTech is a great resource, they know their shiat. They didn't say there are no similarities, they were stating the Merom was a new, ground-up design.

Yonah exists merely because Apple wanted a "new" chip for their Intel transition, and Intel wasn't about to tell a new large OEM/new customer "no."

You mean like when Intel told Apple "no" when Apple wanted Yonah processors before Intel wanted to start making them?

Apple sells a small fraction of what all of Intel's other customers sell, so they had no problem telling Apple to piss off and wait until Intel was ready to start making them for Dell and the other, more important, OEMs.

All I know is I'll be picking up a Merom when the prices come down. Maybe a year after release.

Running in an E1705, M90, and E1405. Why not?? They won't be cheaper on release until maybe 4th quarter if not 1-2 Quarter of '07 ASSUMING you can find them separate from a notebook purchase. I need to pull the FS I got up. After tossing it in to this E405 I am going to keep it since people think $475 is too steep. Also, having all unlocked multis is pretty nice down the road in a few months when I decide to build a desktop again. These things are mad oc'ers...

Got to say, it is nice havng next gen tech for a reasonable price... Temps and batt life are pretty much on mark with CPU marks definitely improved. Though admittedly it is overkill in the E1405 for what I use it for...

Better tech all around. It is great stuff. Get it if you can ASAP. I am loving mine...

Merom in e1705

Did you have to flash the bios or did it drop in and work? I have a line on a T7200 but I don't want to buy it if it will not work in my laptop (new e1705/9400 in the mail now).

Thanks,

Scott

I have a T7200 working just fine in a 9400/E1705 using the latest A01 BIOS. The CPU won't run at full-speed in the A00 BIOS, so you need to make the upgrade.

For a more realistic appraisal of Merom vs Yonah performance, look at the second entry in this blog..

You'll see the performance of the CineForm high definition decoder - one of the most beautifully written multithreaded pieces of code ever written. It's a real life application, not just a mathematical speed test and it quite clearly shows that clock for clock, Merom is almost 30% faster than Yonah. The desktop benchmarks are significantly higher because the CineForm code relies in fast memory access - bigger FSB = massively higher benches.

For me it's going to come down to gaming performance. I don't do a lot of encoding or CPU intensive work, but I do value my gaming performance. For an upgrade to make sense for me, I need to see at least a 20% increase in performance for a reasonable price.

I'd love to see how the Memrom benchmarks comparatively in the gaming world - but I'm guessing that CPU intensive games will obviously see a bigger boost.

I have the cpu and 1705 with the A01 bios and the system starts to boot but I get a blank screen. Any suggestions?

Thanks.

Wait, so the multiplier on those things ARE unlocked?? I could have sworn I asked that back when you first got one and everyone said no!! Have you actually OCed the merom then??

Engineering samples (and EEs, I think) *are* multiplier unlocked.

Engineering samples might be getting cheaper, though.

Well crap, kinda wish I would have gotten one then. But that link was about the conroe, do you think that applies to it's notebook counterpart as well??

They're all using the same microarchitecture (Core), so I'd say yes.
