Which might be better- 9750 or 9890

Thread Starter 
in terms of desktop speed, the athlon FX57 is the dominant chip, but i wonder in these two notebooks which is the better of the two in terms of speed, heat, power, stability, longevity- the new 9750 or the 9890. also, for just sheer gaming power, which is better?

if i buy one of these two, it will be my third sager purchase in 5 years! looking forward to upgrading, it's been around 2 years-

best,
cal

Both notebooks use the same CPUs as the desktop systems. The fastest chip right now is the Athlon FX, and it performs slightly better in games than the Pentium. However, gaming performance is mostly limited by your graphics card. Either system would be suitable for high-end gaming, but if you absolutely must have that extra 5 fps, the FX chips would be the best ones to get.

As far as heat and power go, both chips will run very hot during intensive use, and both have about the same amount of battery life (the Athlon might last a little longer, but not much). Depending on how fast technology progresses, a new notebook with the latest hardware might last you 2-3 years.

If battery life is an important issue, consider the 5720; the Pentium M isn't as powerful as the other CPUs, but it doesn't drain the battery as fast. Since it has the Go 7800 GTX, it will be fine for gaming.

I would rather get an Athlon X2 than any of the forementioned chips though.

I'm actually curious about the 9890. Supposedly (because I read this somewhere, it MUST be true :P) Intel's dual core chips are going to use the same socket the 9890 has. Now of course, this makes me wonder if it's possible for us to buy that chip when it's released (I think new*** has them already!) and stick it in the 9880/9890's. I figure a BIOS update would be required, but it shouldn't be as much of a problem as updating the GPU on the 9880 was. I originally wanted a dual core laptop, but that was when it was schedueled for release (august obviously that didn't happen). Now I start school in a month, and I want to bring this with me. That's why I ordered the 9890, because it would get to me quicker than AMD's version would. So while it's a bummer that I can't stick around for AMD's dual core equipped notebooks, it would still be good to know the 9890 could run Intel's dual core chip. Although I could only IMAGINE the temps.

no it would need a new chipset, the 945g or 955x

and your laptop would burn up, if oyu think 115wats are a lot think 150 on your lap

If the chip ran hotter it could cause issues too. I'd love if they put a few more fan to draw air from one side out the other.

Not sure if i read all of the above accuratly, im kinda tired, but i think i got the gist that you may be considering a pentium D (Intel's dual core) may be in a laptop.

Some brief numbers:
Athlon 4800 X2: Under load 170 W
Intel Pentium D (forgot which model): 220~ W
Intel Pentium D Under load: 315 W

http://www.tomshardware.com/cpu/2005...athlon-19.html (Above data from here)

http://techreport.com/reviews/2005q2.../index.x?pg=15
http://www.anandtech.com/cpuchipsets...spx?i=2410&p=2
http://www.xbitlabs.com/articles/cpu...umd-820_3.html (All the numbers here seem to be about half the other sites? For both amd and intel, no idea)

So, thats TWICE the power consumption under load, and at least 50 Watts more IDLELING, as the athlon x2 desktop chip. If you think the cooling solution for the P4 can handle 315 wats from the CPU alone, be prepared for a few scorches :-)

So, conclusion: I doubt highly highly highly they'll even think twice about putting the current intel p-d into a laptop, simply due to the gargantuan power requirements. Heck, i wouldnt even put the thing in my desktop. I dont think they make a PSU powerful enough for a P-D and SLI.


///edit all the above aside, im re-reading the article and noticing the P4 also has 200+ Watt numbers... If its the same P4s in notebooks, with that high wattage, perhaps it is possible. But my core arguement is the same, thats a heck of alot of power especially compared to a P-M or even a AMD DTR.

It's going to be very difficult to see how a Smithfield (Pentium D 8XX) would be able to fit into a Laptop chassis. The tope TDP of PD 840 is about 135W; and almost no laptop chassis is designed to dissipate 82-3 W on a consistent basis, with a few heavy DTR chasses going upto maybe 95W. And it is typically very difficult to buy third-party cooling solutions, whereas for desktops these modifications are fairly simple.

the d900t and d700t can dissipate 115 watts, the pentium d supposedly is 130w but more realistically 170-200 under load

amd does max power ratings, intel does common

and pc power and cooling turbo cool 510sli would do it
