Windows 8 vs Windows 7(speed)



Windows 8 vs Windows 7(speed)

That's about it in terms of significant feature changes, but Microsoft would have us believe that Windows 8 is much faster than Windows 7 - it certainly works on the same hardware, which removes one barrier to upgrade. (And it won't be an expensive upgrade, either.)
Bill Karagounis, Principal Group Program Manager for the Windows 8 Fundamentals Team, recently claimed that startup times were 40 percent faster than Windows 7 on the same hardware, and that the memory footprint of the new OS is '10 to 20 percent better'. He said that the Windows code base comfortably scales on all devices from tablets right up to workstation PCs, and demonstrated Windows 7 and Windows 8 running on similar laptops, with relatively low specifications (including just 1GB RAM).
According to a demonstration Karagounis ran, Windows 7 uses 389MB of system memory, Windows 8 only 330MB. And this in an operating system that includes more functionality.
Karagounis also showed how an older Asus UltraBook with a second-generation Intel chip could boot from cold in just 8 seconds. However, he said that Windows 8 was intended to be what he called 'always on, always connected'. 'You don't boot and shut down Windows 8', he said. Further, he suggested that the OS was designed to be always running switching on and off instantly like a smartphone. He demonstrated the power draw of an Intel-system on a chip Windows 8 slate, using virtually no power in sleep mode, with only the occasional tiny peak when it checked for or received data.
The device was, he said, connected to the web, working in the background in a mode he described as 'connected standby'. Karagounis sent an IM to the slate, at which point he power draw peaked and the device set off an alert. This status applies to Windows RT PCs, and Intel SoC PCs . In the demonstration the power draw goes up instantly something then happens, and then drops off quickly when so-called connected standby kicks in.

Windows 8 Is Not Compatible



Faster, but negligibly so. With all the added benefits one has to wonder: "just how fast is it?" Well, according to the benchmarks the difference isn't substantial in day-to-day use, the performance assessments focusing on differences that will hardly ever be noticed by Windows 8 users that do not use benchmarks.
An extra few points in Google V8 will go unnoticed in terms of browsing experience when modern browsers in Windows 7 are already fast to start with. Boot-up times are indeed much improved, but shaving a few seconds when booting is like starting a car faster; not going to make any real difference unless the user constantly restarts the computer, which commonsense dictates is an unlikely scenario. The same can be said about gaming or multimedia performance, which improves to a point where only benchmarks and timers can pinpoint the difference.
Basically unless you want to squeeze that last tiny drop of performance, you're better off sticking to the version already installed.

Windows 8 Store lacks relevance and is immature. The first issue with the store is that it's mainly designed for Windows UI apps, leaving the aquisition of Desktop apps to the developer which makes it look like an afterthought. The second and most important is the insignificant number of applications available through Windows 8 store compared to the plethora of apps designed for the "Desktop Windows" making it just a gimmick until the platform matures; it can take some time to take off which is why a rushed upgrade is a bad idea. Facebook, Google+, Instagram are all missing right now, and these are just three examples off the top of my head.

Microsoft account is required. Windows 8 provides two methods of authentication, one using a local account and the second relying on a Microsoft account. The only way to get access to complete Windows 8 functionality is to use the latter, basically forcing you to apply for a Microsoft account in order to benefit from all features. Want to use a Google account? Tough luck. Features like Windows Store only work with Microsoft account. If you do not have one or do not want to create one just for Windows 8 you're out of luck.

SkyDrive integration only. Microsoft places its own services in the first lines of "assault", which can be viewed as a good thing in terms of added functionality, but at the same time doesn't offer an alternative to the people out there using Google Drive or Dropbox that have already paid for extra storage space on the popular cloud storage providers. Then there is the issue of all cloud data being stored on Microsoft's own servers, which might not sit well with some users as far as privacy concerns go.

Windows Defender can't replace a dedicated security software suite. While it provides a certain basic degree of security, Windows Defender is still pretty far away in terms of overall functionality compared to dedicated security software suites and it still doesn't integrate with Windows Firewall to provide a unified interface for the integrated security software. It's addressed only for basic security needs which basically means that it can't offer the same degree of protection as a fully fledged security suite.

Multiple monitor support is only useful to some. Because let's face it, this does not target every Windows user like some of the features do. It has a limited applicability because of the obvious hardware requirements and having the ability to separate the new Windows 8 UI from the Desktop on two separate monitors is not necessarily important when the old Desktop did just fine before. A similar functionality exists already that allows to separate working spaces on multiple monitors; this is just as good when there are not two different interfaces to play with, but just the older Desktop.

The new ribbon desktop interface is different, but not necessarily improved. A few months ago Microsoft decided that an Aero-like look a la Windows 7 is not worthy of Windows 8 and accordingly has removed all transparency effects from the desktop interface. The change was made for the sake of using less resources, directly benefiting tablets not desktops. It's not necessarily better looking and it certainly doesn't provide extra functionality over the older Windows Explorer which is important when defining the term "upgrade." Same functionality, just the look is different.

Windows 8 UI has a higher learning curve and makes simple operations more complicated. A good example of how the new UI makes Windows 8 seem unintuitive is power options, as performing simple operations like shutting down the computer is for some reason more complicated to do than it was with Windows XP or Windows 7. This is just an example of how the learning curve in Windows 8 is higher than with any other desktop operating system to come from Microsoft. Then there is the confusion added by a separate interface. Pressing a button switches from Desktop to Windows 8 UI and vice-versa, which will only encumber inexperienced users that were used to a single place to conduct all operations.

System Requirements for Windows 8


Essentially, those who are running a PC with a Windows 7 logo sticker on it will be cleared for takeoff for Windows 8. Of course, since the Windows 7 requirements were no more demanding than those for Windows Vista, anyone with even a semi-modern PC from the last handful of years should be able to run Windows 8 – at least the Consumer Preview.
Microsoft recommends:
  • 1 GHz or faster processor
  • 1 GB RAM (32-bit) or 2 GB RAM (64-bit)
  • 16 GB available hard disk space (32-bit) or 20 GB (64-bit)
  • DirectX 9 graphics device with WDDM 1.0 or higher driver
There are several more "fine print" requirements and recommendations peppered throughout Microsoft's post (italicized portions straight from Microsoft):

For Metro Apps

One new element to Windows 8 is the requirement that Metro style applications have a minimum of 1024x768 screen resolution, and 1366x768 for the snap feature. If you attempt to launch a Metro style app with less than this resolution (e.g. 800x600, 1024x600) you will receive an error message.

Virtualized Environments

Our recommendation for the Consumer Preview is to run it natively on hardware if you intend to run Windows 8 on hardware when the product is final. Some of you will run virtualized environments for enterprise workloads or specialized purposes, but we strongly recommend that you experience Windows 8 on hardware, as it was designed to run for the majority of consumer experiences.

For Touchscreen Users

Although there are a number of existing Windows 7 touch devices and many are fully supported, we do recognize the touch experience of Windows 8 places a greater demand on a high quality experience than could have been foreseen when manufacturers were developing hardware for Windows 7. Our data is showing that a vast majority of Windows 7 touchscreens will perform well for Windows 8. This means that touch drivers continue to load, and you’ll be able to perform basic touch interactions with a reasonable degree of success. The following systems are a few that we have been using widely in our internal testing and self-hosting, although of course, this is not a specific endorsement of these PCs:
  • HP Elitebook 2760p convertible (Note: This PC is 1280x800 and so does not support snap.)
  • ASUS EP121 tablet (Note: his PC is 1280x800 and so does not support snap.)
  • Dell Inspiron Duo convertible
  • Lenovo x220t convertible
  • 3M M2256PW 22” display (Note: The raised bezel can make it harder to swipe along the edges)
  • Samsung Series 7 slate (Note: This PC has two models, one was provided to attendees at //build/ and the other is a commercial release; the latter has slightly different peripherals and firmware.)

Specific Hardware Requirements

(Note: be careful whenever you adjust your BIOS settings.)
  • Secured Boot requires a new UEFI BIOS, which is not available broadly on PCs yet, but is starting to be made available. If your machine does have UEFI, you can enable it via BIOS settings.
  • BitLocker does not require but performs more seamlessly if your PC has a Trusted Platform Module(TPM). Machines that have this sometimes require it to be enabled via BIOS settings. BitLocker To Go requires a USB flash drive that meets performance criteria evaluated at installation time.
  • Hyper-V requires a 64-bit system with second level address translation (SLAT) capabilities and an additional 2 GB of RAM. You can also enable SLAT via a BIOS setting.
  • Some games and other software require graphics capabilities compatible with DirectX 10 or higher (including some games available in the Consumer Preview and in the Windows Store. We will continue to improve the verification of your system prior to downloading or running software with these requirements). Some games and programs might require a graphics card for optimal performance.
  • If you clean install instead of upgrade (see below), you should check your PC manufacturer's website to make sure you install any specific drivers that they provide there. Many laptops will get better battery life with a power-optimized driver that is specific for that PC (often known as ACPI, Power, or Chipset driver).

Upgrading and Clean Installing

For those of you who have already been running the Windows 8 Developer Preview, you can install the Windows 8 Consumer Preview using the migrate option (just keep personal files), but not the upgrade option (keep personal files, apps, and settings). Or if you prefer, you can of course do a clean installation (keep nothing). The Consumer Preview release does permit upgrading from Windows 7, and will run the integrated upgrade advisor to check on any things you might need to look into. Please keep in mind that there is no rollback after an upgrade installation. We also strongly recommend that you perform a system backup prior to an upgrade, migrate, or clean install of Windows 8 Consumer Preview.
Also note that the final release of Windows 8 will not support upgrading from any prior Windows 8 "Preview" release, though the migrate option will still be supported. In any upgrade scenario, you can run the Disk Cleanup Wizard to remove the previous installation in order to free up disk space. The download will also support boot from USB for a completely clean installation as well.
