I will buy a laptop computer, but its very hard to choose between Pentium M and Duo Core processor, anyone knows the difference in these two? and which one is better? btw, what brand of laptop thats more powerful than others?\nps. i dont do gaming, alot of graphics and word processing.

You're buying a loptop, so power use will be important to you. Batteries life is terrible with high power components, including the CPU. \n\n=======\npower\n\nAnd that's the first distinction. The Pentium M was designed for minimum power consumption in a Pentium compatible CPU. So your batteries will last longer. \n\nThe Duo Core CPUs are really two CPU cores in one chip. IF the operating system, and application design (which you can't affect) support them properly, such a CPU can be much faster than a single CPU, all other things being equal. But the Duo Core chips use more power, so your battery life will suffer, all other things being equal. This may be worth it, if you are doing computationally intensive stuff, and if your software / operating system can take advantage of the additional CPU. Otherwise, it will make little difference. \n\n========\ngraphics performance\n\nOne computationally intensive use that's common is gaming. it takes a good deal of effort to calculate color brightness and shading for each pixel in a scene, and there are lots of scenes. In fact, it takes so much computational power that vendors have largely given up on making the CPU 9or CPUs) do it all. Recent graphics schemes, the ones that make game images snap and sparkle, during play require a lot of work from some processing chip. The best of the graphics processor chips have more computational power than nearly all CPUs, and they require comparable electrical power (draining batteries still more quickly). It's this reason that accounts for laptops rarely having cutting age graphics performance or CPU speeds. In particular, the graphics hardware in most laptops has low power needs and is hardly up to recent graphics performance standards. \n\n==============\nCPU architecture differences\n\nAnother issue, which will matter only if your use of the laptop needs it, is differences between various Pentium editions. Intel has added more instructions, and used different internal architectures, as they have designed new CPUs. These include new instructions (the SSE, SSE2, etc groups) and the 64 bit EM64T additions to the basic 32-bit core, in emulation of AMD's Opteron and AthlonFX approaches. But for the moment, until your applications can use those extensions, and until your operating system is fully 64-bit compatible, your EM64T CPU will be running mostly in 32-bit mode. And recent Pentium 4 CPUs have included something called Hyperthreading which speeds up some kinds of programs substantially. And, of course, various Intel CPUs have included more or less fast cache on the CPU chip itself. If this is done sensibly, cache (and more cache) can have dramatic effects on many kinds of program execution speeds.\n\nDepending on detailed comparisons between the CPUs you're considering, some (or none) of these differences between CPUs might be significant to you. See Intel's spec sheets for the CPUs you're looking at for the differences. \n\n\n\nIn your case, since you aren't a gamer, the merely adequate graphics hardware in most laptops will probably be acceptable. Your mention of graphics programming might mean image manipulation, and either CPU should do in that case. Photoshop and similar programs don't have to handle graphic manipulations in real time, and so their demands are much less for satisfactory performance than video (or near video -- such as games) processing. \n\nWord processing simply doesn't have so high requirements. After all, any CPU sits doing nothing for eternities between key presses, even for fast typists. There's lots of available cycles from most any CPU in most any word processing operation. \n\nSo, for you, which would be better? mostly, it depends on the work you'll be doing and the applications with which you'll be doing it. If they can take advantage of the processor features in one or another CPU (not something you can easily find out, probably even from the software de

well it really depends on what you are going to do with the machine... Every processor has it strengths and weaknesses, sometimes they are designed that way to provide for a specific market.  You could ask and get so many different answers based on peoples personal opinion from thier personal uses of the processor.  A math or physics student, programmer or graphics artists would tell you that the pentium 4 is the best.  Someone who does a lot of wireless stuff and general computing would most likely say the Centrino and someone who does home computing with no real stress in any particular way for the system would say the celeron, but then of course for price those would be different.  Buy a system that does what you need for a good price and is competetive as far as upgradeability.  After all no nead buying a jetski if you don't go to the lake.

I have an Acer laptop, and i like it.... Intel or Amd are both good processors, I have an AMD,but I highly reccomend that you do NOT get a celeron processor, they work good for a couple months, then they are the slowest dang things.

I wouldn't trust anyone other than dell or toshiba for a brand name. Go with a pentium 4 if in your but probably out of your budget. I am not an AMD fan and refer you mostly to an intel processor - again, I trust Dell and Toshiba - they have a great reputation.\n\nJeremy, bugon.com

Right now, AMD makes the best processors in my opinion. This doesn't mean that all AMD processors are better than Intel processors, however, just that the top of the line AMDs are the best you can get in my opinion. You are on the right track getting dual core. Don't look at clock speeds if you are comparing Intel to AMD, as they rate them differently and AMDs report slower clock speeds even though the chip may be faster. If you really want to get down to it, checck the benchmarks that http://www.tomshardware.com have. They will help to show which processors are faster at which tasks.\n\nIf my answer was helpful, don't forget to consider rating it as the best. Thanks!

I am currently putting my new system together.  I settled on the AMD64 X2 because I could take advantage of a dual core processor ( I use linux exlusively). I haven't looked at the pentium D so I could not comment or make a comparison.  I have built a few AMD's and a few pentium 4's .  I find the AMD 64's  more responsive and a better bang for the buck.

Well I would say both are good brand right now for gaming laptops specially Dell XPS also has good tech. support after sales ( couple of my friends work for it ). Go for dell XPS M1710 they got 4 varients of it on basis of their design & hardware components.\n\nCheck out the link below for the range which suits your budget you'll really find'em awsome ( I'll suggest you to go for the one which says mulimedia powerhouse $ 2,794:\n\nhttp://www.dell.com/content/products/features.aspx/cto_xpsnb_m1710?c=us&cs=19&l=en&s=dhs\n\nYou can also check this one from alienware its called Aurora™ m7700 Mobile Gaming Powerhouse its for starts from $2,679 however one thing you should notice that dell gives you better configuration for the same price range.\n\nLike dell gives you 512 mb graphics card instead of a 256 on this one. Alienware has a bigger harddrive but wats the use if you wont enjoy most of your bulky high defination games.\n\nSo compare them and take a decision ( I say dell is better in this price range )\nCheck the link below for alienware :\nhttp://www.alienware.com/product_detail_pages/Aurora_m7700/aurora-m_features.aspx?SysCode=PC-LT-AURORA-M-7700&SubCode=SKU-DEFAULT\n\nI 'll suggest you to check this brand called Pro-Star as they are giving a lot more of inside stuff then other at the same range ( have'nt heard about their after sales support ) but its a mouth watery deal as far as the hardware is concerned. I want you to check this two models by them 9068-3A, 9068-4A the only diff. between 'em is the processor its AMD 4600+ & 4800+ for $ 2,629 & $ 2,679 ( not much of a diff. )\n\nhttp://www.pro-star.com/index.cfm?mainpage=productdetail&model=9068\n\nyou can try this one by gateway if you want your mom to have a bit of relaxation on the monetary side :\n\nhttp://www.gateway.com/products/GConfig/proddetails.asp?system_id=nx860xl&seg=hm\n\nI say you should read this review before you make a descision & hey take the pro-star seriously its a good deal :\n\nhttp://www.bizwaremagic.com/best_gaming_notebooks.htm

For anyone looking for a monster laptop without extreme pricing, I'd suggest www.xoticpc.com\n\nYou can customize a very powerful machine and less cost than alot of the competition.  When they start putting out dual core machines running Vista, I'll be buying from them.

intel core 2 duo\nfamily t7x00 not t5x00\n\n>> base t7200 is 2.0 ghz, 667 mhz fsb & 4 mb l2 cache > which is awesome\n\nturin struggles at 512 kb to 1 mb l2 cache, further divided between the 2 cores ! <256+256 / 512+512>

Out of those - go for the pentium 4 - but the new intel's - core 2 duo's are really kicking a$$ at the moment. - I'd seriously consider looking at a low end one of those even if it's a little over budget.\nhttp://www.newegg.com/Product/Product.asp?Item=N82E16819115005

true indeed, core 2 duo ee rocks nd amd dual cores r much more expensive with lesser performance. i'm sure intels quadcore with shorter pipelines will(or may) outperform amd but u never know whats in store hope 4 the best\ntc lol\nnd beware of the web

Get Alienware.....awesome machines....as long as you don't mind spending a little bit more for it. If money is an issue and you want something cheaper, I recommend a Dell. Don't go with Compaq or HP if you can avoid it, they are just proprietary, production machines.

You hit it right on the nose.....\n\ni have been building / repairs PCs for 12 years. In that time I have preferred AMD over INTEL unless a customer came to me with a specific need. I personally (4 PCs in house) use AMD for gaming, work and general apps. AMD is cheaper because you are not paying for the name. They have proven many times (I am not just being bias) that the chips outperform the Intel counterparts. They run cooler, and do not need as much power (except the new mobile core duo, they are nice). In my own personal opinion, take it how you want it, AMD's perform much better in a "Desktop" PC while Intel has a good lock on the laptop market.

I would say the Pentium 3 would be better. But for games I wouldn't really try to play much at all with either of those CPU's.

I have 2 Dell core duo laptops that I want to sell off right now. \n\nOne is 1.66GHz and the other is 1.83GHz, they both have 1GB RAM. Honestly, you may not be able to notice the difference in speeds. And the difference in prices of those 2 that I'm selling is $40.\n\nSo if that 40 bucks is not much to some people, they will go for the 1.83GHz, but personally, the 1.66GHz will do just fine to me.

Core duo has two processing cores which makes it faster - can handle more instructions. Centrino being older is slower and was kind of a bundle deal where if it said centrino it had to have wireless access (not the cpu - the computer)

You know this topic is too extensive to cover here. \n\nThere is some good reference material covering both types of processors here: http://ourworld.compuserve.com/homepages/r_harvey/doc_cpu.htm \n\nIn Pentium class processors, there also model-specific registers  http://ourworld.compuserve.com/homepages/r_harvey/doc_cpu.htm
