normal app walatanam machan 32 64 wadi wenasak nee but networking wala

windows server HCP
VMware v
hyper V
citrix xendesk

wage ewata aniwaa 64bit maa onee ewa 32 wala wada naa ( wada kalath slow :( ) oya office windows 7 wagenam 32 th ekayi 64 th ekayi wage thamayi :P :P

Machan then photoshop 64bit, premier cs5 is only 64bit, excel on 64bit has a big advantage over it's 32bit counterpart. so are these not normal apps?

The reason we don't see a speed improvement in these general apps is that we never/rarely use the 64bit optimized options. therefore we think there's no benefit.

    64 බිට් හරි 32 බිට් හරි කියන්නේ motherboard එකේ සහ processor eke Bus වල තියන line ගණන. එතකොට 32 bit වලින් access කරන්න පුළුවන් memory locations ගණන වෙන්නේ දෙකේ තිස් දෙවන බලය. ඒ කියන්නේ 4294967296 ( = 4GB) ඒක නිසා 32 බිට් computer එකකට theoritically 4 GB වලට වඩා RAM දාන්න බෑ. නමුත් 64 බිට් වල දෙකේ 64 බලයක් වෙනකම් address පාවිච්චි කරන්න පුළුවන්. ඒ කියන්නේ unlimited වගේ තමයි. මීට අමතරව integer, float වගේ variable වල ප්‍රමාණ වෙනස්වීමක් වෙනවා. ඒක බලපාන්නේ application developers ලට. 64 bit computer එකකට 4GB ram ගහලා 32 bit OS දැම්මොත් පෙන්නන්නේ 3GB විතරයි. හැබැයි 32 bit නම් 4GB ම පෙන්නනවා. මේක Windows විතරක් නෙමෙයි Linux වලටත් පොදුයි. 4 GB වලින් එහාට යනවනම් 64 bit අනිවාර්යයි. (ඒ කියන්නේ processor එකයි motherboard එකයි දෙකම 64 bit වෙන්න ඕනෙ 4 GB වලින් එහාට යන‍වා නම්)

    dinukap4 කියලා තිබුනා "if u have less ram MAX 16GB use-86bit" කියලා. ඒ කථාව නම් වැරදියි. 84 bit කියලා computer ජාතියක් නෑ. x86 කියලා නම් කියනවා. x කියලා දාන්නේ 486, 586 වගේ ඉස්සරහා අංකය මාරු වෙන නිසා. x86 හැම ‍computer එකක්ම 32 bit.

    32 bit Appications 64 bit OS එකක කරදරයක් නැතුව පාවිච්චි කරන්න පුළුවන්. ඒක OS එකෙන් handle කරනවා.

    බිට් ගාන වැඩි ‍උනා කියලා performence වලට කිසිම වෙනසක් වෙන්නේ නෑ. (64 bit එන්නේ high end computers වලට නිසා සමහරු එහෙම හිතනවා ඇති)

    මෙන්න උත්තරේ

    64 bit os is faster than 32 bit..coz 64 bit has more bus width between northbridge and CPU .
    let me explain this

    we all know data transfer in a computer like this 110010101010100101010101010101
    so 64 bit os and cpu can transfer maximum length of 64 bit..but if we are using 32bit cpu and os whether there is a data length more than 32bit ..that that data should be converted into the 32 bit like(ex(it is 9bit) ...100101010 into 1001 X [FONT=&quot]105[/FONT] )
    so there should be some delay for this converting..... in 64bit cpu and os there is no converting because of its wider bus width

    The reason you don't see a dramatic speed u is that the application you use are not 64bit optimized. If you use the 21bit and 64bit same application your pc you will see that the 64bit programs runs faster.

    in essence 32bit apps on 64bit pcs runs a tad slower or the same speed as 32bit o/s's but uses a bit more memory. on the other hand 64bit on 64bit is faster and memory utilization is optimized.
    Hmm well I put Windows 32bit and 64bit isn't that enough :S :S
    mmmm and I have put Lightroom 32bit and 64bit will that be enough???
    well leave Windows since it's a OS
    but I use Lightroom in both 32bit and 64bit environments there may be a difference in performance but it's not "dramatic" as you sayy... that is what I'm saying....
    but as I know you'll see a considerable change in softwares like 3d max and maya... since they do hell of a lot of calcs.....
    speaking as a normal PC user you won't feel that much a difference.... :) :)

    Ya, that's correct macho. mostly it's the number crunching apps that benefit most. the other issue is that though apps are said 64bit majority of code is still 32bit hence the reason there's no dramatic effect. but if a native 64bit app is being used (i wonder whether they exists at all) there would be a big difference. hope you get the point i'm making.

    Machan 32 & 64 bit is the width of the DATA-BUS of CPU.
    Just think of a High level road that you can go some times only 2 vehicle at a time & think about a road that goes 4 vehicles at a time simultaneously. Same way the data bus will work inside the motherboard ....
    new CPU's e.g. CORE2DUO to latest are support for 32 & 64 bit operations.
    >FIRST you can check whether your processor is support 64 bit operation by Intel website's reference information page for your CPU
    >SECOND check whether your motherboard is support 64 bit operation
    by motherboard website's reference information page
    >THIRD check whether 64 bit operation is enabled by BIOS
    >FORTH install 64 bit Operating system like Windows 7 Ultimate 64 bit \ Or Redhat Enterprise Linux 64 bit

    ***If you have done this you will be able to enjoy 64 bit operation which will increase you PC's speed dramatically !!!!:shocked::shocked::shocked::shocked::shocked::shocked::shocked:


    :no::no::no:
    This is a very common misconception. What we call 32bit and 64 bit is NOT the width of the data bus. 64 bit data buses were available from the very earliest Pentium processors.

    What 64 bit refers to is the INTERNAL architecture of the CPU, in that a 64 bit CPU has 64 bit registers and 64 bit internal buses. A 64 bit CPU can process 64 bits at a time, unlike a 32 bit CPU. The advantage of performance is due to this fact, not because of increased data transfer to the processor

    It follows that the internal Memory Address Register of a 32 bit CPU was 32 bit and could only hold around 4B of memory addresses (which is where the limitation comes from). A 64 bit processor also will be connected to a 64 bit Address bus so that all 2^64 memory locations can be addressed

    machan RAM eka 4GB nam 64bit install karapan
    mokada 32bit wala 4GB RAM walin 3GB witarai pennanne

    eeta adu e kiwe 2GB RAM pc walatat 64bit daanna puluwan kisi awulak neha
    eeth 64bit dala pelak software support karanne neha
    eeka wenama 64bit version eka hoyagana oni OS 64 nam :D
