AMD released its first 64-bit processors that year. While sales were
decent, there was no consumer 64-bit operating system to take advantage of the
hardware. Then finally in
2005, Microsoft released Windows XP in 64-bit form. Yet again the 64-bit
industry seemed set to explode.
The release was met with much criticism, though. Part of the problem was
necessity -- even in 2005 the average user did not need more than 2 GB, in most
circumstances. Another major hitch was driver support. All drivers
had to be rewritten to work with the new width.
Despite these difficulties, three years later, for the first time, the 64-bit
industry is at last healthy and growing. With virtually all new processors
from Intel and AMD supporting 64-bit, 64-bit OS's are flourishing as
In a recent
blog, Microsoft's Chris Flores reported that 20 percent of new Windows
systems connecting to Windows Update were 64-bit. This is up from a mere
3 percent in March. He stated, "Put more simply, usage of 64-bit
Windows Vista is growing much more rapidly than 32-bit. Based on current
trends, this growth will accelerate as the retail channel shifts to supplying a
rapidly increasing assortment of 64-bit desktops and laptops."
Retailers such as Best Buy and Circuit City are also catching on to the trend,
offering largely 64-bit OS-equipped machines for their most heavily advertised
models. Many manufacturers are also throwing in their support; Gateway
transitioning its entire desktop line to 64-bit in time for the
back-to-school shopping season. To put this in perspective, in its first
quarter, only 5 percent of Gateway's notebooks and desktops were 64-bit.
In its third quarter, a whopping 95 percent of desktops will be 64-bit and 30
percent of notebooks will be.
Aside from the increased memory, one other possible cause for adoption is the increased
availability of software that takes
advantage of the increased capacity. Adobe's various graphical design
product lines have been revamped for 64-bit. Another drive may be gaming,
which is typically memory hungry. "64-bit versions of Windows will
begin to find their way into high-end gaming notebooks, which increasingly are
being used as high-end notebook workstations as opposed to strictly gaming
systems," said IDC analyst Richard Shim.
Finally, it may just be inevitability that is helping 64-bit. While the
upgrade will only provide subtle benefits to the majority of users, even power
users, it is an iterative advance. And like most advances, after a period
of reticence, people are finally warming up to it.
quote: The installed base of 64-bit Windows Vista PCs, as a percentage of all Windows Vista systems, has more than tripled in the U.S. in the last three months, while worldwide adoption has more than doubled during the same period. Another view shows that 20% of new Windows Vista PCs in the U.S. connecting to Windows Update in June were 64-bit PCs, up from just 3% in March. Put more simply, usage of 64-bit Windows Vista is growing much more rapidly than 32-bit.
