We have been following the path of Windows 8 pretty closely including trying out the Developer’s preview on some existing tablet hardware (which lasted all of 4 days). So far we have a good feel for the OS and what is nice and what is not. We have talked at length about the mistake that we feel the MetroUI is both for the tablet market and the desktop.  But it is the tablet market that we are most interested in. We know that there will be more x86 (64) based tablets in the future especially with the popularity (relatively) of the ones that are currently out (and that use a full Intel Core CPU and not an Atom). But how will ARM fare even a quad core ARM SoC when Windows 8 and all of its anticipated bloat hits it?

This is that thing that has us wondering. Well we think we have an answer as ARM has just announced 64-bit capable processors. The ARMv8 is a going to be a new specification for ARM processors that is capable of executing both 32 and 64-bit instructions. This means an extended memory profile (not to mention performance) for applications that can handle the 64-bit memory block addressing. But more than that these smaller and lighter CPUs will be heading to the enterprise for some specific tasks (which means the rumors about a future ARM based version of Windows Server are true). Imagine being able to utilize these low power lost cost CPUs to run Domain Controllers, Web Server and other system that do not require the heavy lifting of a full x86-64 CPU. It will save companies quite a bit of money, and what is more… what starts in the enterprise ends up on the consumer’s plate.  We have a sneaking suspicion that these new CPUs will end up in the consumer market faster than usual though as the press release about this mentioned Microsoft and nVidia directly. nVidia has made no secret that they want their Tegra SoCs to represent 50% of their revenue which means the consumer market for sure (with some enterprise products just for fun).  

As of right now, the first devices will not be announced until 2012 with the first prototypes hitting in 2014. This means that while we have a good wait ahead of us it will give Microsoft time to fix what is buggy in Windows 8 just in time for the new 64-bit ARM CPUs to launch.

Microsoft just announced that they are including Hyper-V with the next versio n of Windows. This now makes the third (in our opinion) most interesting new feature to be included with Windows 8. We have briefly talked about the other two (USB optimizations and the new File Management system). This new feature, however, is something that could have a big impact... on VMware. You see right nowVMware is one of the leading companies in virtualiation and their products are in use by a large number of people (incuding us). Of course Microsoft tried to include a type of Hyper-V in Winows 7 (XP-Mode) but that did not go over so well. This time things are a little different.

The Hyper-V that will be included with Widows 8 includes a llittle more than the XP Mode that is on the current flavor of Windows. For starters you wll not be able to run this unless you have a 64-bit CPU and at least 4GB of RAM. On top of all that you will need to have a CPU that supports Second Level Address Translation. Now this is not a networking term but relates to memory addressing and is a feature that has only popped up in the last few generations of CPUs from Intel and AMD. I wonder, if there is any chance that Microsoft will enable this feature for the ARM archiceture and allow a sort of "dual boot" mode with the guest OS taking the lead in system resources and the Host becoming a background task just to keep the Guest operational. In all honesty I am just waiting to see what tablet manufacturers are going to offer Windows 8 drivers for existing ARM tablets. I will be very interesting to see things a they unfold leading up to November of 2012.
