difference between laptop and PC..

[vamsee]

Hi,

I am using laptop having Windows 7, intel i3 - 2.4GHz, 4GB RAM, 500GB Hard disk. My question is, will PC having the same configuration works as speed as laptop? if not which one is faster and why?

thanq

A 2.4GHz Core i3 processor for a desktop will usually be faster and better than a 2.4GHz laptop Core i3 processor.
The desktop PC will draw much more energy.
Laptops may have 5400RPM hard disks, whereas desktops mostly have 7200RPM or better.
4GB RAM in desktop may be faster than 4GB RAM for laptop as there are other considerations to be made besides memory space, such as bus speed, latency, etc.

In general, the PC having similar-looking configuration (eg same frequency processor, same storage capacity, same memory, etc) will be faster than the laptop.

Hope this helps.
Tahmid.

PC Desktop by default is always faster and have better response from PC Laptop which is portable device adjusted with portable and on battery (low power) jobs.

Just to add one note, for fair comparison, the desktop PC has to be complete system completable components, in this case yes the PC is faster than the laptop because it doesnt need to compromise the power for the battery time

What you mean under "Just to add one note, for fair comparison, the desktop PC has to be complete system completable components," ?

If you don't mind,can you explain this in brief???

Interestingly, with modern processors, if you want good performance, you need to keep them cool. This applies to multicore Intel processors - SpeedStep I think they call it?
Which means that certain PCs can run better, if they have good cooling.
I mean PCs where the cooling fans and ducts are actually engineered as opposed to a fan with blue lights
randomly slapped in to a location on the PC case.

Of course, the best computer is the one you have when you need it, hence the convenience of a laptop.
If you want to do something intensive, it could be offloaded onto a server.
For 90% of desktop use-cases, a laptop should be sufficient in performance I would have thought, nowadays.

Also for good performance chips need to eat power, in laptop chips are like on energy diet. I respect strong and expensive families of models, but on end its just portable device with some bad picture on screen and hot heat exhaust.

Laptop mobility and low power consuption is major advantage against desktop PCs.

Who have extra additional money should buy one laptop and one desktop PC, and mistery is solved.

Comparable components

Components used in laptop doesnt exist for desktop PC.

Hard disk on dekstop are different speed and power, CPU are different, RAM different, GPU completely different, .... all is different except USB ports and other jacks like J45, audio,...

 

[Tahmid]

All parts need to be comparable. eg. A laptop core i7 will be faster than a Celeron mobile. A laptop SSD will be faster than a desktop HDD.

 

[tpetar]

You can put SSD HD in desktop PC, also i7 you can have in laptop PC. Celeron is old history, badly presented in some models today.

Actually, even if you made a desktop PC with hardware having the same model as the one of a laptop, it would differ at hardwarelevel. Both desktop and laptop PCs have to be kept cool, or you'd probably end frying french fries over your CPU, eventually turning your PC in a door stop. Laptop PCs have very small space in the case so the CPU cooler will have a very bad time cooling the CPU. This is why laptop CPUs are made so they always stay on alert for any heating that may damage the hardware. This difference is made in the circuitry which always checks the temperature (aside from the tens or hundreds of softwares provided to automatically decrease CPU usage/power and consequently heating). If there's too much heating, even if the laptop has a huge load to run, it'll be limited for hardware's safety. Now, as suggested before, desktop PCs also use much more power - because they have where to get it from. A desktop PC is connected to the powerline 100% of the time so the baddest thing could happen is that power gets missing. Laptops instead only have a modest battery which will provide sufficient power for some time, not forever. Electronic components work fine when they have good power supply, but when laptop's battery starts getting low, electronic components also start getting low on performance. On some old PCs people could notice the audio volume getting worst when the battery was getting low. Hopefully, we're not having those issues anymore, but still, the problem persists. To run at full speed some electronic components must use more power or they'll fallback to a lower speed. Hard drives will run at lower RPMs, RAM will run at a lower read/write speed and the CPU itself will be the first slowing down. As a counterpart of this, using more power (assuming it's available somehow) means more heating, so the temperature control will still limit speeds based on heating. An identical desktop and laptop CPU, compared at the same temperature and same load on the same hardware, have different performances where the one on the laptop is fairly behind the desktop one.
Now don't get disappointed by this, it's just the nature of the desktop and laptop PCs to be this way for (mostly) physical reasons. Anyway, even laptops have huge performances that could reach desktop ones (just make sure you spend some money on it ), but if you have to choose between a desktop and a laptop because of performance - definitely go for desktop. Portability though is a huge benefit of laptops, it may save you time and space, and you may keep you laptop with you at home and at work - you could not do the same with a desktop, could you?

maintanance wise desktop is prefered to laptop even a keyboard costs 10 times to that of desktop
