That would be a nice machine with little compromises when it comes to speed and portability, well as far as I'm concerned anyways.
You want power. One word "Sager." Sager's are the sh*t for desktop replacements. hit up "www.pctorque.com" to see what they have to offer. I know if you hit their forums "www.notebookforums.com" they released today (!!!!) a new notebook that rivals the power of most modern desktops. Check it out there worth a look, even if they are not your deal the forums will give you a good place to find good laptop info.
You obviously have not read any benchmarks for the M6805/7...... some guys are already breaking the 12000 barrier in 3dmark2k1..... in addition, show me a sager that can match these 2 numbers:
Business winstone 2004: 21.2
Content creation winstone 2004: 26.8
Portability? 3 hours on battery for the most powerful CPU available seems like a good deal. Remember, the P4 is VERY dependant on good memory (low latency) to perform at its best, and the current DDR400 sodimms are not there yet.
By the way, the Athlon-64 in the emachines is the mobile version, rated at 62 W max, 40 W typical at full speed and only 13 W at the mimimum operating state...... the battery life is even more impressive if you keep in mind that the machine has a widescreen and the battery is a humble 8 cells 4400 mAH at 14.8 V.......
You're right about all that Alex as I would love an AMD64 book as well. But that said...let's be real and realize that the 9600 in the M6805/7 books that are pulling 12000 are heavily overclocked and by that token I can tell you that my Dell is doing the same (as well as a Sager). Once again...same chip...not like the ECS books have some miracle iteration of the 9600 in it. It doesn't. I'm never going to pretend my 9600 that comes in my Dell 8600 pulls off some miracle numbers because they got a special batch...um...no it doesnt...neither does the ECS...
That said, I agree with you that as a CPU...again CPU, the AMD is the BEST balance of power and energy consumption. HOwever...let's get off the 3dmark2001 numbers as somehow people throw these numbers as if it's the gospel.
If you're taljking desktop replacement...it's not science. Performance is the sum of it's parts. Anything else you're going to pay for its warranty, "build quality", name brand, paint job etc. Add it up.
Sorry to hijack the original post. To answer is a Centrino "worth" it. This isn't hte answer u want but ask yourself this. Do you honest to God see yourself away from an AC outlet often enough to sacrifice the raw cpu performance? In day to day usage...that's most games, word, excel, IE...then yes the centrino is more than sufficient as the 9600 is going to bottlenecke before the centrino. However, if u're going to do some heavy CPU intensive stuff then shoot...grab that AMD64. If you NEVER see yourself going to be away from an AC adapter...then the answer is obvious...screw battery life. Personally, I went from a P4-M to a Centrino. I have NEVER been away from an outlet for more than an hour. I do a lot of face to face meetings with clients...sometimes at Starbucks etc. The most I've had my book open to show them anything has been less than an hour. Looking back...I would've gotten an AMD64 as well. Hope that helps.
As usual you post a very good and coherent essay :light:
Guys, Kevin is adressing the main question. How important is battery life for you? If you need to be away from the outlet for extended periods of time and need good performance, a P-M LAPTOP is worth it. If you need the longest battery life, but don't need a lot of performance, a transmeta crusoe will be good choice (I know, I know, a P-M is more powerful, but then we come back to the original assumption as the K8 mobile is more powerful tna the P-M)
Need to stay on battery for several hours, with minimal weight and the most demanding thing you will do are some spreadsheet calculations? A sharp laptop with a crusoe is in your future
Need battery for over 4 hours, a lot of features, don't like to carry a lot and sometimes need to play a game or run something more intensive? A P-M is in your future.
Are 3 hours of battery power enough for you, don't mind some weight, need to run intensive applications and want to have the most powerful CPU available for notebooks? An Athlon 64 is for you
You want the BEST features, don't mind batery life and weight is no concern at all? A P4 DTR is for you
Tight budget, wouldn't mind 4 hrs of battery life and some horsepower is welcome? An Athlon XP-M is for you

PS. NEVER in all my trips to the USA I left the battery of my 2100Z below 35%. Flight time is aprox
4 hrs, plus the wait, but keep in mind that you cannot use electronic devices at take off and landing (spans of aprox 20 mins each). In addition, you have to eat (at least I always do) so those are other 20 minutes. In fact, my M6805 battery covers perfectly the air time, and I even get some 20 minutes of internet at the airports..... good enough!
I am assuming most of you that fly will have shorter flight times, so 3 hours are OK.
