3/15 It's been a while since I bought a notebook. Is there any reason to
pay extra $100 to upgrade from XP Home to XP Professional? How about
Intel Pentium M Processor 7x5, do they run at decent speed relative
to say, P4? And what's the difference between 1) Crystal View XGA TFT
and 2) SXGA+ non-crystal view TFT? ok thx
\_ You definitely want a Pentium M for the power savings.
\_ XGA = 1024x768, SXGA = 1400x1050
CrystalView is just the name they gave to a better LCD; don't get
the last gen LCD
\_ Comparing a 1024 and a 1400 IBM screen, the 1024 is brighter with
slightly slower refresh, and the 1400 has a very wide viewing
angle, but less brightness when viewed Head-on.
\_ Home has problems working with more than I think 5 computers on a
LAN and has a bunch of other esoteric cripplings that make it
unusable by most businesses. For home use, 'Home' is fine.
YMWTS: http://www.microsoft.com/windowsxp/pro/howtobuy/choosing2.mspx
\_ How about dialing in and running VPN to access corporate network?
Does Home work in this case?
\_ Clock-for-clock, 7xx Pentium Ms do more work that Pentium 4s.
The 7xx series also use a lot less power, which means better
battery life and cooler thighs. Pentium M is lower voltage, lower
frequency, bigger cache, and shorter pipeline.
\_ Generally, multiply the Pentium M frequency by 1.5 to get the
equivalent Pentium 4 frequency. So a 2.0 Ghz Pentium M is like
a 3.0 GHz Pentium 4.
Anyway, you definitely do not want a Pentium 4 notebook.
Runs too hot, uses too much power, notebooks are too heavy, they'll
break from all that -- it's a desktop CPU.
\_ Pentium 4: Desktop CPU, very hot, high power and clock rate
Pentium 4M: Pentium 4 at lower voltage and power
Pentium M/Centrino/7xx: Different design philosophy, very low
power, lower clock rate but more work per cycle.
\_ FYI, they don't make the Pentium 4 Mobile anymore
Also, the Pentium M not only has a different design
philosophy, it was engineered from the ground up as a mobile
CPU.
\_ XP Home does not have IIS. Pro does for development purposes.
\_ M$ is really good at bundling things and defying antitrust laws.
\_ My gf wants a cheap laptop(against my advice.) Are there any
significant difference between Celeron M 360 and Pentium M 725?
Besides the cache I mean. I'm mainly interested in performance
and battery usage.
\_ http://www.tabletpcreviewspot.com/default.asp?newsID=178
Celeron M's are Pentium M's with half the L2 cache and no
SpeedStep (always runs at the list frequency).
See the article for more details.
Pentium M > Celeron M >> Pentium 4
\_ Cool. Thanks for the link. Her older celeron laptop was
dog slow, but this page looks good. -pp |

Many prospective buyers ar e wondering what kind of computer do I need? Once a decision to select a mobile device such as a notebook or Tablet PC, more challenges lie ahe ad. And the question that is becoming t he most difficult of all: "What kind of processor do I need?" As you may seek answers to some or all of the above, we urge you to post your questions in our forums! There are three consistent issues I have seen come up in the forums on both TabletPCReviewSpot and our NotebookRe view site - getting the most for your money, yet getting good performanc e and sufficient battery life. Did you know that choosing the right CPU can make a big impact on all thr ee issues in question? In this editorial we will focus on one of the mo st important and misunderstood choices consumers have to make - the proc essor. Is great battery life, and speedy performance possible from a Celeron? Celeron Myths and Urban Legends The Intel Celeron Processor was first introduced in April of 1998, offeri ng "exceptional value and reliability for everyday computing tasks ". A t first the Celeron was simply the key to affordability of otherwise exp ensive choices in personal computers. Consumers who planned to put off purchasing a computer due to the high cost, were now actively shopping t o get a PC. Many of these Celeron-based machines were purchased by fami lies and individuals who only required basic computing horsepower for ev eryday tasks. It wasn't long before power users decided to join in and pick up low cost Celeron-based machines for servers, secondary machines, etc. It also w asn't long before those users started to recognize the processor's limit ations, becoming quick to criticize the Celeron, calling it a "brain dam aged Pentium". Just mentioning the Celeron to most technofiles would in voke the reponse "The Celeron is a piece of crap". Today in the days of which mobile compu ting is commonplace, the Celeron is not even close to that original chip from 1998. Furthermore, today's chip has absolutely no relation (outsi de of the name) to the additional susequent Celeron models and updates r eleased over the last 6 years. On June 5th 2004 the all new "Celeron M" was introduced by Intel. At tha t time, and even today still - the Pentium M is all the rage. The Celer on M was still pushed aside by many as "scrapped silicon". With the pas t reputation is this newly branded Celeron M worth even consideration? The Intel Celeron M This new incarnation of the Celeron (for mobile computing devices) is cur rently being offered by many Tablet PC and Notebook manufacturers as an alternative to the Pentium M Costumers face a very attractive offer in this case, as the Celeron M models with almost identical specs. in ever y other category sell for around $200-$300 less. The Celeron is a "piece of crap" so skip it, a no-brainer decisi on. If that is your answer and you are the least bit concerned about sp ending your hard-earned cash wisely, then we suggest you read further! The easiest way to do this is to compare it to it's dizygotic twin, the Pentium M -image source: Tom's Hardware Guide Left-The Celeron M 13GHz Right-The Pentium M 14GH z So what is the difference here? You will see that the Celeron M says "1300/512" - that is a 13GHz cloc k speed with a 512KB Level 2 cache. On the Pentium M it says "1400/1M" - translates to a 14GHz clock speed with a 1MB Level 2 cache. Difference #1: The Celeron M has only 1/2 the Level 2 cache size as the Pentium M "Next slide please"... Illustrated is the area that con tains the 512KB of deactivated cache. Also highlighted isthe super deep sleep enabling "Speedstep-Unit" that is non-functional on the Celeron M And... difference #2: The Celeron M does not enable the same "super deep sleep mode" as the Pentium M Duking it out: Performance Benchmarks VS. Using the industry standard Sisoft Sandra 2005 benchmarking software, we pitted some heavy hitters against one other to find out the true raw pe rformance each processor delivers. Note that we compare the 13GHz Cele ron M to the 14GHz Pentium M and the Pentium 4 16GHz. We also include d the AMD Athlon XP 2000 as a "non-Intel" reference CPU. With consideration to the -100MHz clockspeed difference, this "value" chip delivers a tie with the Intel P entium M Also the P4 gets a wash by both processors. The AMD, well th at's another story, but pretty impressive delivery huh? CPU Multi-Media Benchmark Same story, with regards to the -100MHz clockspeed, the Celeron M ties wi th the Intel Pentium M The P4 lags closely behind. It would be intere sting to see how this newer chip fairs. Sin ce the Celeron M has been robbed of the advanced deep sleep capabilities of the Pentium M, you will lose out a bit on battery run time. This is really dependant on how often you allow your machine to go to sleep dur ing periods of inactivity. If you are one who continually uses your mac hine while it is on, then shut down when you are done, your benefit from the enhanced Speed Step technology on the Pentium M will be minimal. The Rational The sleek Gateway M320 - the Celeron M option starts at only $699! Both of these CPU's offer quiet, low heat generating performance. They a re both indentically capable of being used in the newest "thin and light " form factors. Both offer almost exactly the same performance per rate d clockspeed under just about all circumstances. So with that in mind, before you buy ask yourself some questions: Want to save a few bucks? Would you rather spend the extra $$ for a larg er hard drive or DVD writer rather than the processor? How important is it that you get that extra hour per charge? Are you goi ng to push your machine to the limit with gaming. Better hope your mach ine includes an independent (not shared) video chip. Since when did I set out to empower our readers to make informed buying decisions? I have done a fair amount of research and hands on testing prior to writing th is editorial. the Pentium M and wh at we have discussed in this story, I definately recommend that you chec k out Tom's Hardware Guide. In final, I encourage you to post further q uestions or invoke more discussion on this hot topic in the forums, simp ly click the "discuss this story" link at the bottom of this page. |
