Ddr3

Are any laptops available with DDR3 Ram yet? If not has anyone announced anything, or anyone know when laptops will start having it?

Thanks

I know there are others too

 

You can order them now. I am not sure anyone has them in hands yet. Most give mid August delivery dates. And there are many.

 

Toshiba X305, among a few others based on Clevo and other manufacturers.

At this point, there is not really a performance increase between DDR2 and DDR3. Don't fret about that, especially if there is a DDR2 notebook you like.

 

Will it make a difference in the future? What about battery life? I am leaning toward the HP dv7t w/ blu-ray and was going to wait until DDR3 came out. I will mostly be using the laptop for online poker, blu-ray, and some gaming. I haven't done much PC gaming before, but want something that will play higher end games. I'd prefer not to go too much over $2k, but can if needed to get something I really like. I'd like it to be as "future proof" as possible and can wait a couple months if needed.

 

you will notice absolutely no difference in performance from dd3 memory. apps will still take the same amount of time to run and execute as long as the specs are the same.
ddr3 is a complete waste of money at this point, as it is new, and carries a very high premium, which most users will not want to pay, especially since its not going to make the system any more responsive.

Buying a futureproof laptop is not possible, so dont waste excessive amounts on trying to make one so called future proof. There will always be new things coming out around the corner, and no price premium can buy 10yrs in the future's technology today for notebooks

I'd say DDR3's biggest advantage over DDR2 memory is it's power consumption. It basically does what DDR2 memory does, but using lesser power, and w/ slightly better bandwidth transfer speeds. This equates to better batt. life, and slightly better performace proficiency overall than DDR2 memory.

Edit: I personally don't recommend anyone to purchase a laptop at this moment w/ DDR3 mem. It really would be a waste of money..as KTRON pointed out above. But by next year, DDR3 mem. will basically be mandatory at least for Intel's next upcoming chipset microarchitecture codenamed Nehalem. In the second link scroll down to the Memory bandwidth comparison.

 

Thanks for the words of advise. How in the world do I figure out what to buy than? I was originally leaning toward a dell studio 17, and now the HP dv7t. I would prefer 17 ' 1920x1200 resolution, blu-ray player, good video card, and able to multi task without lagging. My price range is ~$2k.

 

unfortunately performance advantages in DDR3 won't be seen until intel releases their Nehalem chip which has a built in memory controller. I don't know what the ETA for the laptop version is.

 

The power savings between DDR3 and DDR2 is only 0.3 Watts per memory stick. In other words, sufficiently little that it is very unlikely you'll notice the difference. Perhaps you would on a 12.1-inch, Ultra Low Voltage processor, integrated graphics laptop with low brightness - 0.6 Watts savings might give you 10% additional time there. But with a 17-inch laptop and a dedicated graphics card, it is not going to be noticeable. I have a 15.4-inch with dedicated graphics, and even with minimal brightness and no wifi my laptop uses 16 Watts minimum. DDR3 would give 4% savings - 12 minutes or so with my 85-Watt, 9-cell battery. Any additional benefit you would have from Montevina efficiency improvements would be canceled out by the extra screen size. So you're looking at pretty minimal gain from DDR3 for a fairly significant price increase.

 

I don't think that is the issue. While I agree Nehalem will offer much your statement is incorrect. If you believe it would be the 1333Mhz RAM then well no comment as I have not studied enough.

 

Are you saying all of Montevina is over rated? Or just the DDR3 RAM? Is it worth buying a Centrino 2 processor?

 

is montevina better then penryn? would a hpdv5t last at least 3 years for gaming?

 

depends what games you play. montevina is the platform while penryn is the processor, so you can't say one is better than the other since you are comparing two different things.

This laptop will have 4GB worth of DDR3 ram and a 9800m GTS for under $1500.

 

Performance advantages in DDR3 won't be visible unless they release the higher bandwidth modules....!!

Montevina is not over-rated, the DDR3 ram is a bit better than DDR2 (but the real difference would be seen at higher bandwidths and after the fall in price)....and the 'P' Penryns are good whereas the 'T's are just the same old thing (almost)....!!

I guess you have thought and researched more about this than even say, intel, because this way (taking into consideration the LCD and stuff) even the new Penryn CPUs won't save you much battery on the mainstream (15.4", 17") notebooks....

 

Well true one is a platform and one is a CPU but you can't compare them because Penryn is a part of Montevina. See my point?

And here is a chart I just posted in a different thread but relevant here also.

Time to first bit

Mhz	CL	ns/cycle	total time (ns)
533	4	7.5	30
667	4	6	24
667	5	6	30
800	4	5	20
800	5	5	25
1066	7	3.75	26.25

Time for 5 bits

Mhz	CL	ns/cycle	total time (ns)
533	4	7.5	60
667	4	6	48
667	5	6	44
800	4	5	40
800	5	5	45
1066	7	3.75	41.25

 

blahhhh. That seems pretty nice, an I just ordered a HP dv7t.

 

fujitsu a6210 among others...they make great laptops

 

Sony VGN-Z Series.

 

I think I saw this while I was running into other forum, but I think newst Fujitsu model has DDR 3 options.
