What makes this computer better than the others?

Question

The most expensive one-
Processor: Intel Pentium™ 4 3.0 GHz HT (with HyperThreading Technology)
Memory: 1 GB DDR RAM
HDD/FDD/CDROM: 250 GB, 1.44 FDD, DVD-Rom

The other two cheaper ones-
Processor: Intel Pentium™ 4 2.6 GHz
Memory: 1GB DDR RAM
HDD/FDD/CDROM: 250 GB, 1.44 FDD, DVD-ROM





Processor: Intel Pentium™ 4 2.6 GHz HT
(with Hyper Threading Technology)
Memory: 1 GB RAM
HDD/FDD/CDROM: 250 GB, 1.44 FDD, CD-ROM

So what makes the more expensive one better? Is it really important to have the goodness, what difference does it make?
And what's this GHz HT about anyway? o.o

First computer is $620 AU
Second is $580
Third is $600

(No $2500 pricetag here. ;)

Answer 1

Price difference is mainly due to processor difference. Pentium 4 3.0Ghz (HT) is faster. HT gives the processor the capability to operate as if you have 2 processors. BUT HT also makes the processor run HOT. Most users just turn off HT to reduce heat.

Dual cores made HT obsolete. The processors you listed above are obsolete. They are now relatively slow and consume more power. Better consider newer processors. There are cheap variants.

The new Core 2 Duo easily beats the old Pentium 4. Here are some comparisons on budget Core 2 Duo with the older Pentium 4 (dual cores also):

The new Pentium E2140 and 2160 are cheap but uses Core2 Duo high performance technology.

Answer 2

For the extra 20 or 40 bucks, I would get the 3.0 ghz with ht. It will be a faster pc. The GHZ is the speed of the processor. The HT allows the processor to function faster in certain applications. The combination of the two will be a faster pc, and for that little extra money is well worth it. The faster the better, because the way things change, it will last you that much longer before it needs to be replaced. I would also plan on adding another GB of Ram, as well. Then you would be able to run any application you wish, and fast. Plus if it has Vista, 1 GB is the bare minimum, and won't be anywhere near as fast as you expected untill you up it to 2GB ram. More than 2GB would be a waste, unless you are doing video intensive applications.

Answer 3

You dont supply enough information.

How do you measure good? There are an infinite number of ways.

Personally I feel you should match the computer to the task. If all you need is a VT100 terminal ($20) then why spend $3000 on a bleeding edge laptop? Spend $20 on the terminal, and invest the other $2800 somewhere thats going to make you money.

What are you going to do with it? Surf the internet? Wal-Mart has a $200 computer for doing that. Doing calc I math? Get a TI calculator for $30. Performing highly aggressive and demanding scientific calculations that would take a year on any lesser laptop, buy the bleeding edge Sager. Sager was the manufacturer that alienware bought from, and re-wrapped their computers in before they were bought by dell.

You can get a laptop that would cost you $6000 when bought at dell, but from sager it costs only $3000.

my point: match the computer to the task as part of the definition of good.

Answer 4

The p4 3.0Ghz should not be that much higher those CPUs have been out for over 3yrs now. But the HT is better HT means Hyper Threading which in turn is faster. I have Server tower as a backup computer with a Dual CPU mobo that has 2.8Ghz HT CPUs /4gb ram and 1TB of hdd space I will put up agains any so called dual core or quad core and it will be faster. Hyper-Threading enables different parts of the CPU to work on different tasks concurrently. In this way, a CPU with Hyper-Threading appears to be more than one CPU.

Thanks

Answer 5

By the one in the middle. There is only a 12% difference in speed between it and the top model. You'll never notice the speed difference.

The last model possibly uses slower memory which could affect the performance significantly.

Answer 6

what makes it more ep. is the extra .4 ghz ..
Gigahertz, generally abbreviated GHz, refers to frequencies in the billions of cycles per second range. Giga is the standard multiplier for 1 billion, and Hertz is the standard unit for measuring frequencies, expressed as cycles or occurrences per second. One GHz is equivalent to one thousand megahertz (MHz).

GHz is commonly used when discussing computer performance or radio frequencies. In computers, GHz most often refers to the clock speed of the central processing unit, or CPU; the faster the CPU clock can tick, the faster, in general, the computer can process data and instructions. In 2000, Intel and Advanced Micro Devices achieved a marketing and technical milestone by releasing the first CPUs to run at 1 GHz. Speeds have subsequently reached 4 GHz.

In radio communications, GHz is used to define bands of the electromagnetic spectrum. Different bands will be assigned different uses. S-Band, for example, is a band of spectrum between 2 and 4 GHz. Common technologies such as Bluetooth, wireless internet (WiFi) and cordless telephones operate in the S-Band. L-Band, between 1 and 2 GHz, is used for satellite communications and Global Positioning Systems, or GPS. Other notable bands in the GHz range include Ku and Ka, used by satellites as well as by police radar guns.

Devices transmitting at or near the same GHz can interfere with each other. This is caused by the wave-like nature of radio waves; peaks in one wave can be offset by lows in the other wave, thereby nullifying both waves. The closer in frequency the two signals, the more pronounced the effect. Microwave ovens, for example, can interfere with Internet connections because they emit radiation at the same frequency as that used by WiFi routers. Similarly, Bluetooth and WiFi compete for the same frequencies, and using them concurrently can affect throughput.

Answer 7

To be undemanding, it would not make a huge distinction. in case you elect velocity and performance, i might propose the 2d one with the HyperThreading technologies as properly. till you are the main hardcore photos fashion designer it won't make an exceptionally huge distinction as you're finding on the suitable of the line processors good there. Any of them might do, yet i elect to propose quantity 2.

Answer 8

GHZ is Gigahertz and HT is hyper threading

Answer 9

the most expensive one is the is the fastest
how much more is it expensive?
because all of them has only 1 gb ram
dont go for the 3rd one either 1st or 2nd

Answer 10

Why not buy a better duo core pc. because this will be outdated very quickly. infact it probably is.
