    Hi everyone,
    So I got this laptop with the following specs:

    Core i5 2450m 2.4GHz
    4 GB DDR3 RAM
    500 GB SATA 7200 rpm

    And a desktop with:
    Core i3 3.06 Ghz
    4GB DDR3 RAM
    500 GB SATA 7200 rpm

    Now the lappy is way slower than desktop even though it runs on a better CPU... both have the same Windows 7 64 bit installed.

    Yes, I know its not a tech support forum but... it is lounge :) So... any tech geeks here? What do you think could be the problem?

    Try closing unecesary programs that are running in the background using ur task manager....also try canceling unecesary start up programes when u boot ur laptop through systemconfiguration......if this fails scan ur laptop for malware and virus infections...if that also fails then backup ur files and install a fresh windows..hope that helped:D

    There are quite a few of them running in the background... But I'm more concerned about the startup time as the laptop has a cleaner startup 'sequence' (not sure what the right word is for this) than desktop but it still starts very slow.

    They're not the same specs. :p

    These are two different processors, other than the type, the laptop has a 2.4GHz processor and the desktop has 3.06GHz so if you're definitely sure that it's not the stuff that you have on your laptop then it is most likely due to the processor speed of the desktop even though it's an i3.

    Also, the motherboard can make a big difference.

    Hah yeah the CPU is definitely different in both but isn't the i5 better than the i3?
    I saw the benchmark scores on CPUBenchmark and the i5 certainly looks better than i3.

    Laptop parts are always undervolted compared to their desktop counterparts. Even though it says a certain clockspeed, you won't be getting it during boottimes due to the load being processor light and more HD heavy. Same principal w/ HD, can't spin at max rate due to being physically smaller and having to be heat-concious.

    Try running an msconfig on the lappy and disable anything you don't need on startup.

    the laptop's running on a mobile version of the i5, which is designed to be smaller and use less energy than it's desktop counterpart, and thus performance will be worse. that combined with the lower clock rate makes it worse than a desktop i3.

    I have a few computer geeks on Skype and Winchester was one of them lol. This is what he says.

    First off you haven't said what is running slower on the two? It could be graphics oriented (as we don't have info on the graphics cards). Either way, check your hardware specs under system on the control panel, ensure all the RAM is noted by the OS, and check what your processor speed is showing as. Open up task manager, check what is using your active memory and see the percent of memory usage. If this is too high you may have a background progress (either legitimate program or malware) that may be eating up your memory and bogging you down. If you see a process running that takes up a lot of memory and you're not familiar with it kill the process, then open up the start menu and type in msconfig. This will bring up the core config menu, click the startup tab and look at programs that automatically start on bootup. Disable any that you know you don't need. Also grab a good anti-malware like MalwareBytes and run a quick scan to ensure the system is clean. If that doesn't work trying throwing a few more details my way and I'll help out.

    Thanks all for replying.
    tacopalypse's reply makes a lot of sense and I think that is could be the reason for the lappy being slow.

    Guess I'll just bear with it.

    Most slowness issues are not hardware related, so even if there is significant difference in hardware, that should not translate to dramatic differences in performance.

    Most frequently, manufacturer-installed crapware uses up system resources. Slow start-up times are either this or there are errors on start; services that are trying to launch and cannot. They might try & fail 3 times before Windows gives up and moves on.

    Fragmented hard drives are a major cause of slow-downs, and Terminate and Stay Resident programs like "DiskKeeper" (software that constantly runs and defrags the HD) are a sham and a fake and slow the machine down worse than the fragmentation. I use this as a screen-saver, so it only runs when I'm not using the computer:

    http://www.mydefrag.com/

    Control Panel>Administrative Tools> Event Viewer and under Windows Logs look at "Applications" and "System" and look for chronic errors particularly on startup. This could get hairy, so you could attach a .txt file of the log to a post here.

    http://bootracer.en.softonic.com/

    That will give you an objective measurement of your boot speed, i.e exactly how many seconds it takes to get to desktop. Having an active PW will cause irregular results because the time it takes to enter the PW is included in the results, so it's best to disable the PW while test. This will give you some idea if whatever changes you are making are having a positive effect.

    Even in 2012 bigger is still better.

    Notice the " m " in i5 2450m. Its a mobile processor meaning it uses much less power than desktop processors making it a little slower.

    If laptops were as fast as desktops with same specs then servers and other stuff would be mobile too

    This is why I just don't do laptops anymore - that and the heating issues that I keep running up against. Now I have 3 desktops at home - one for me, one for my Wife and one for the boys to play on. Unless I have money burning a hole in my pocket, I won't be getting a laptop anytime soon. ;) Not only do my desktops always run faster, but they dissispate heat better, are easier to open up and work on and are less integrated. So if something fails, I can quickly pop it open and replace it - unlike most laptops which takes hours and maybe 2 or 3 engineering classes... ;)

    Glad Tacopalypse gave the good anwer... it makes sense to me.

    My only problem with laptops are the batteries, they all seem to die out on me, probably because most of the time my laptop is plugged into the socket.

    FWIW, as a general rule "less is more" when it comes to software. The more you can uninstall, the more system resources (CPU, memory) you will have for doing other things. One highly false notion that evil black-hat marketers try to sell people on is the idea that installing something will somehow magically make things run faster. It's like saying that loading your trunk with bricks will make your car drive faster. The more crap you have running, the slower the computer is going to run. It's always a balance between system resources and what is using them, so when people focus only on the hardware they are missing 1/2 of the entire equation.

    I make a regular practice of going into "Programs and Features" and getting rid of everything and anything I don't use, most particularly those softwares that run every time Windows starts. Words like "updaters", "customer enhancement", etc... (they're obvious, just look at the name with a marketer's eye) usually indicate a software that can be gotten rid of. When in doubt, run a Google search and see how necessary it is.

    Another big area of misconception is the idea that the more Anti-Virus softwares you have installed, the safer your machine is. Completely false, for a wide variety of reasons. What multiple AV softwares WILL do is dramatically slow-down the system. Security is never an absolute, but instead is just one variable in a complex equation, and the other variable is User Experience. If you have so many AV softwares installed that the machine is incapable of doing anything, then what's the point of having them? You may as well turn off the machine. Or, you can maximize performance, control your behaviors (the primary means of getting infection) and have no AV software at all. The best solution for most people is a compromise between these two extremes, but it's important to note that there is a spectrum between maximum performance and maximum security and that you sacrifice one in order to achieve the other.

    Laptop's hard disks spins at 5,400 RPM with 5.55ms latency where the desktop drives spin at 7,200 RPM with 4.16ms and Thats just one reason. I highly recommend you to get an 64/128 GB SSD and replace it with your laptop's hard disk. Its blazing fast when compared to 5,400RPM drives. You can install windows on that SSD and connect an external hard disk to store data's.

    Yes, you should add a SSD with your Hard Drive. If you dont have place for a ssd just get a 7200 or 10800 rpm hard drive.

    You can even upgrade your ram to 8 GB if you want.

    Also you may have a virus go install norton or ESET 5

    -----------------------------------------------------------------

    One more : Click on your battery icon and select high performance. It fixes all lag issues

    As someone who has built many computers, I will offer my 2 cents.

    #1 Reason - Mobile processor vs desktop processor. It's funny how the CPU manufacturers downplay the difference between the desktop processors and mobile versions. In general, mobile versions are stripped down versions of the desktop processors designed for coolness and power efficiency. If you look at most desktops, they have some decent heatsinks - that's because normal processors running at normal speeds generate lots of heat. Notice that the mobile processors don't have a huge heat sink? They channel less voltage and that means less heat - but also less speed.

    #2 Reason - Bus size. On a desktop computer, the bus speed (communication between the cpu and everything else) is usually larger than than on a mobile device. This causes a general slowless communicating to hard drives, graphics cards, etc.

    #3 Reason - Memory Speed. Everything happens in memory. Because laptop memory is designed to run at lower voltages in most case, that also means it runs slower.

    #4 Reason - Graphics Card. The build in graphics cards are also designed to use minimal power and also, most of them are using part of your ACTUAL RAM as video memory. This slows you down in two ways - first, you have less memory for the computer to use and 2nd system RAM is never as fast (well, hardly ever) as dedicated video memory on the board.

    #5 Reason - CPU Speed - The two CPU's are different speeds, so if you look at it... your desktop is 3.0GHz and your mobile is 2.4GHz. That's roughly 20% difference in speed.

    #6 Reason - Hard drive speed. Most laptop hard drives are at most 5400rpm's, whereas you can get desktop drives as fast as 10,000rpm's... though technically, you COULD buy one of those any put it into laptop - but FEW manufacturer's do that as it ads significantly to the price. The hard drive is used not only to load programs, but also for virtual memory. With Windows swapping back and forth to the hard drive, this can be a big draw on speed.

    There are other reasons. But the one's above are most likely the main reasons.

    SSD's allow the computer to start faster, allow faster processing while it's running and use less power, giving longer battery life. A "must have" for a professional.

    I also agree with others on the superiority of desktops vs. laptops for static home & business use. One reason not mentioned is fragility and cost to repair. Desktop parts are cheap and easy to find, and frequently a laptop that hits the pavement from 3 feet costs more to repair than a new one. I don't think it's smart to invest in a expensive & fragile laptop without a compelling reason such as mandatory travel, etc...

    BTW, while I'm on the subject I have a brilliant idea for a solution to the portable & expensive laptop vs. cheap & static desktop dilemma, if there are any moneyed investors out there. Note: The first thing I'm going to grill you on is the money, so for the mildly curious no I'm not going to just give-up my brilliant idea for someone else's entertainment (or for them to steal).
