for 32 bit and 64 bit

Unnoticed, PC users already felt at home with 32-bit applications for about 10 years. Popularized by the availability of the Windows 95 operating system and several successors. At the time of the introduction of Windows 95 is also a milestone in the transition from 16-bit applications, the 32-bit. And now PC users will go through the same period.If 10 years ago, at that time, the popularity of 16-bit applications from displaced with 32-bit applications. So now it's time to start 32-bit 64-bit resignation replaced.The presence of the operating system Windows 64-bit desktop version, Windows XP Professional x64 Edition, the more sure that it was time to start switching to 64-bit.Some argue, Windows XP Professional x64 is not a revolutionary product. It is the result of an evolution, which also never happened before. And indeed it was time, considering it is so long, since the availability of 64-bit processor on the market.What is 64-bit?To you who are still wondering, what is the meaning of 64-bit to read the following explanation. If not, you can move on to the next section.In the processor, the number of bits length or number of states that direct data can be processed in one step. As 32-bit CPU, processor means to process an instruction along the 32-bit in one clock cycle. So the 64-bit processor is a CPU capable of processing capacity throughout the 64-bit instructions in one clock cycle.Data output that has been processed CPU will then be incorporated into the memory. By increasing the ability of data length that can be processed CPU, then indirectly also improve memory performance.64-bit processor in the x86 Processor Architecturex86 architecture that is the basic design for desktop processors from Intel (and Intel compatible). Starting from Intel 8088 to the era of the Intel Pentium 4 and Intel Pentium D. Also for AMD until AMD Athlon class.Initially, AMD 64-bit processor called x86-64 extensions. But in 2003, AMD changed the name and call it AMD64.For the first time to draft a 64-bit processor in the x86 architecture started by AMD. Reference technical documentation, start provided by it starting from August 2000. It is intended for software developers, to adjust and optimize the formatting commands available on AMD64.Intel EM64T is based on AMD64 architecture. The fundamental difference in the two is the specific commands are only owned by Intel. As Hyper-Threading technology (HT) or SSE3 instructions.IA64 is the term used by Intel on Intel Itanium architecture and Intel Itanium 2. In contrast to the AMD64 and Intel EM64T are made based on the x86 architecture. IA64 only has limited compatibility with the x86.So, What Is It 128-bit RAM?32-bit processors are already working with 64-bit memory module. This refers to the work done data bus between the processor and the RAM.Some of the latest systems, with support from motherboard northbridge chipsets, allows the processor and RAM to work on a faster data bus. Utilizing dual-channel design. By the manufacturer, this is often referred to as 128 -bits. Although the actual naming is not entirely correct.What is the maximum amount of RAM that can be Used in Windows 64-bit?Maximum amount of RAM that can be exploited by a system depends on three things. Ie processor, motherboard, and operating system.Most of the latest motherboard chipset, supporting up to 4GB. While most 32-bit applications with the Windows operating system, will only access memory up to a maximum of 4 GB. This is specific to Windows XP.Probably most of PC users, also has never utilize the maximum amount of RAM capacity up to 4 GB. However, the amount of 4 GB is a limitation that was annoying to use a PC workstation. As in the use of design CAD / CAM, image manipulation, and high-end video. And of course do not miss the game, which also will take advantage of this.In Windows XP Professional x64 Edition, the maximum RAM limit to 128 GB. With a capacity to handle virtual memory to the size of 16TB (terabytes).With the presence of 64-bit era, with an Application Usage Instructions How Long Like x87 FP, MMX, 3DNow!, And SSE?x87 architecture floating-point addition is separate from the processor. Some knew him as a math co-processor chip. Some of them we know it is 8087, 80,287, 80,387, or 487SX. Starting on an Intel 486DX, Pentium, and so on, x87 already available in the built-in on the processor. X87 main task is to do high precision calculations. As in the CAD application (computeraided design) and spreadsheet applications. Especially for the x87 has been deemed no longer effective. So on AMD64 architecture, the task was replaced by the so-called "flat register file", which has a total of 16 entries.For instructions on SSE2 (Streaming SIMD Extensions 2), AMD64 still hold on. SSE2 can be used both for calculating the 32-bit applications and 64-bit. SSE2 is faster than relying on x87. SSE2 instructions have also been mengakomadasi on MMX and 3DNow!It further allows the AMD64 and Intel EM64T work more optimally. Good for 32-bit applications, as well as 64-bit applications.Windows Operating System Which Is Already Supports 64-bit computing?For the desktop, the operating system that already supports 64-bit from Microsoft is Windows XP Professional x64 Edition. Actually, Microsoft also has several other operating systems already support 64-bit technology. However, it is not entirely devoted to the needs of desktop PCs. Call it like Windows Server 2003, Standard x64 Edition, Windows Server 2003, Enterprise x64 Editon, Windows Server 2003, Datacenter x64 Edition.Some versions of Microsoft operating system also supports 64-bit technology. Like Windows XP 64-bit Edition 2003 (discontinue); Windows Server 2003, Enterprise Editon with SP1 for Itanium-based systems Intel CPUs. However, this operating system is not compatible with 64-bit processor for desktop such as AMD64 and EM64T.For desktop users, are likely to refer to the operating system Microsoft Windows XP Professional x64 Edition. It became available in May 2005. If you are interested to know further, can see it in http://www.microsoft.com/windowsxp/64bit/default.mspx.Like Windows XP Professional x64 Edition?Windows x64 Edition still uses the same user interface compared to Windows XP Professional Edition. Some upgrades done to support 64-bit processor for desktop with AMD64/EM64T architecture. The increase primarily on the ability of these operating systems handle memory. More can be seen in the table.Windows XP Professional x64 Edition is made in the same codebase with Windows XP Service Pack 2. So also with the additional facilities available. As the availability of support for wireless devices, Windows Firewall, Windows Security Center, Bluetooth infrastructure, Power Management, and support for. NET Framework 1.1.How fate of 32-bit applications?Considering there are many applications that still run on the basis of 32-bit, of course, this becomes a pretty important question. Operating system Windows x64-bit is still possible to run 32-bit applications in 64-bit Windows environment. Backward compatibility is limited only to 32-bit applications. And 64-bit OS has been unable to run applications 16-bit or MS-DOS. Please note also the installer files are available. Had say setup.exe file is still in the 16-bit formatinstaller, the installation process will not be done.What about gaming? Some popular games are still running in 32-bit applications can still be executed. This is possible because of the availability of such a Program Compatibility Wizard (PCW). In Windows XP x64 Edition is called the Windows on Windows 64 (WOW64). Form a layer of sub-system emulator that does 32-bit applications in 64-bit OS environment. This is to ensure the two are not mutually berinterfernensi.This is also done to prevent the collision between the two. One of them by separating the use of DLL (Dynamic Link Library) between the two. 32-bit applications will not be able to access 64-bit DLLs. Vice versa.Is There a Performance Improvement between 32-bit and 64-bit?If you expect miracles increase PC performance, using the OS and software 64-bit, then you will be disappointed. No significant performance improvements between 64-bit and 32-bit. At least with the use of PCs and applications are available now.So what benefits can be obtained from the 64-bit? Windows 32-bit only able to allocate a maximum of 4 GB of RAM and 2 ~ 3GB address space (depending on application). Compare this with the x64 Edition. He was able to handle up to a maximum of 128 GB of RAM and 8 TB addressspace for each process application.Physical address-space memory and a larger enable 64-bit applications to access memory more freely. Reducing the paging file to disk, and indirectly will improve overall performance.As for speed, most likely there is no significant improvement. Given the clock speed processor that is used on 64-bit applications similar to those used during run 32 - bit on AMD64 and EM64T processors.What about 64-bit Application Development. Masihkan Need to Wait Long Availability of 64-bit applications?Up to now, the availability of an application that works natively on 64-bit OS is still limited. But with the launch of Intel's Pentium D processors for desktops that are equipped with EM64T instructions, will certainly help mengakselarsi this.Likewise, the availability of Windows XP Professional x64 Edition. It is estimated that the end of 2005, we began to see applications running natively on 64-bit.With the increasingly widespread availability of 64-bit processor for desktop, and comes with the launch of the operating system Windows XP Professional Edition, then start popping up applications that already support 64-bit computing. For gaming this is true. One of the games that have been optimized 64-bit is the game titled "Shadow Ops: Red Mercury". Utilizing the optimization of memory and improved multimedia capabilities possessed 64-bit operating system. It would be much improvement can be felt. Starting from the detailed drawings that can be displayed, both texture and detail the background, until the increase in AI (artificial intelligence).Other games will also provide a patch for 64-bit is "Far Cry". A game FPS (first person shooter) with a 3D engine CryEngine. Real-time editing, bump-mapping, static lights, network system, integrated physics system, shaders, shadows and a dynamic music system are some of the features provided CryEngine. Hopefully, the patch for 64-bit on the CryEngine will improve the AI, Polybump mapping, environmental advanced physics, destructible terrain, dynamic lighting, motion-capture animation, and total surround sound.
