and don't forget that you can always replace the processor with the 35w low-voltage one hioctane.

Interesting review FuSoYa. Seems to be on par with the other AMD64+9700 notebooks. My question is, wouldn't the performance be much better if they had used PC3200 mem instead, and a higher rpm hdd? How much of a performance bump would you see if you got a G3 with 1024 PC3200 ram and a 7200rpm hdd? My guess is quite a bit...but I'm sure others with more experience would be better suited to answer that.

The battery life doesn't seem too bad though, 2.5hrs for a desktop replacement seems good. I wonder what kind of "throttling" was going on they were talking about. Isn't that supposed to happen depending on what how much the system is being taxed during use?

Severe Heat Issues do not exist in AMD processors

I know some laptops have localized heat problems, like in a corner, or in a section of the keyboard, but this thing was hot all over! By hot i mean hot enough that you could burn yourself on it if you touched it for too long.

I admit that they had that particular model on for a few days playing a dvd, but i dont think it would take long for the temps to rise to such a level. Personally, I bet the a64 3400+ with 9700 graphics would get even hotter, and I wouldn't expect any overclocking potential. I would steer clear of this one and wait for a better athlon notebook.
I've read some stuff on AMD's website regarding heat issues and such. With AMD's Power Now technology, such heat issues that exist in intel's pentium DTR processors for notebooks do not exist in Mobile AMD or DTR AMD due to its intelligent Power Now technology. This is a quote from AMD's website regarding the Power Now technology ( http://www.amd.com/us-en/Processors/...%5E964,00.html )--> "[Power Now] Allows the processor to dissipate less heat under normal operating conditions, providing a cooler and quieter-running notebook."

On another part of its description, it says "[Power Now] Provides performance on demand when required by the application (therefore, maximizing battery performance)." It implies that this powerful DTR processor exhibits Pentium Centrino behavior. For a DTR processor, I am pleasantly surprised that AMD is able to offer this kind of capability. So you guys who have concerns about heat issues should expect a much cooler and more POWAful system on the Mayhem G3 compared to the Mayhem G1. I'm looking to buy one soon for college. I'm extra excited.

Can anybody explain me the difference and advantages/disadvantages between the
chipsets SiS755 whch is used in Uniwill 258KAO and VIA K8T800 + VT8235CE which will be used in Sager 4750?

I talked to reps at both ABS and GamePC and they both told me that the SiS755 chipset runs PC3200 ram at the actual 400 MHz, whereas the VIA chipset will only allow ram to run at 333 MHz even if you have PC3200.

I'd like to see some hard evidence that this is true with these notebooks because I think I will be ordering one soon...probably the ABS G3. That way I can return it within 30 days if I'm not completely satisfied.

So, which Athlon 64 is the G3 using??
Is it the newer "cooler" specifically mobile one??

It is using the 3400+ DTR version. a mobile version of the 3400+ is slated to come out a year from now.

Flyby, did you check these two reviews from techreport and anandtech?

http://techreport.com/reviews/2004q2...5/index.x?pg=1

http://www.anandtech.com/chipsets/showdoc.html?i=1922

They compared these two chipsets along with others and it seems to me that they used PC3200 400 MHz. RAM for both of them. Both the chipsets had almost identical scores in all the benchmarks, though I didn't find any ref. to the point you mentioned; I may be wrong since I know so little about it.

So, I assume this puppy is going to be hot, any way you slice it???
(weird thing is that a guy at abspc just told me that the 3400+ is a mobile version...I assume he must be incorrect)??

I'm hoping it's not hot. And if it is i'll just return it. ABS has a 30 day return policy so i'm not overly concerned. I will have to pay for shipping though if i do return it. Don't worry i'll be posting a review.

As for AMD processors it is a bit confusing. DTR (Desk top replacement) chips are used in notebooks so they are confused with the mobile kind.

There are:
3200+ 3400+ DTR chips
3200+ 3000+ mobile chips
2700+ 2800+ low power mobile chips.

So far I haven't heard of notebooks using the DTR chips having any real heat issues. You can search the forums who have purchased the Mitac 8355. No one has complained of overheating or processor throtteling. The AMD chips are running cooler than the P4s. Also the AMD64s use AMD's Power Now utility to optmize their battery use.

The low power and true mobile versions run cooler though have less horsepower. It comes down to what you want to use the notebook for.

No one really knows yet how the Mayhem G3 will perform. All i know is that another guy ordered the same set up from Game Pc. We'll be comparing specs and benchmarks when they come in. So wish us luck.

well, technically the DTRs would be considered mobile chips if they're designed to be used in mobile computers aka lappys... but yeah if they were talking descriptons then yes they would be wrong. i'm still stuck on the acer ferrari though, great laptop for a pretty decent price (~$2150 after upgrading the RAM and hd). and it has the 9700, too, as if anyone didn't know that.

I think all of the laptop versions of athlon 64 even the dtr models may be able to use powernow which would allow extended battery life.

This is true. Any AMD processor made for a notebook wil support PowerNow. The desktop chips have the same thing called Cool and Quiet which does the same thing though there is little motherboard support for it yet.

Does anybody know if there is a lighter version of the G3 out there?? Everything about the laptop turns me on except its weight (7.7lbs) which is why I hold the G2 (6.4) above it. I still have an extremely long wait of one month before I must order something, but I'd like to know as soon as possible.

The ferrari 3200 by acer may work for you. 8 pounds isn't very heavy. its about the weight of a newborn baby. although i think i was a pound heavier then. if the weight is troublesome try a notebook backpack. probably less likely to get stolen as well.

All i know is that Sharp is also releasing an AMD64 notebook using the 2700+ cpu. Similar to the Ferrari 3200. And alienware should come out with their own AMD64 notebook soon. Haven't heard of anything else.

Wow a 2700 would be less powerful than the acer. might get better life though. Alienware will probably be really expensive although it will probably look pretty cool. But alienware generally scream "steal me" the loudest because a lot of people know about them. They are advertised quite a bit.
