AMD takes a more practical and less disruptive approach to the challenge of 64-bit computing.
Key extensions to the reliable, proven, high-performance x86 instruction set not only preserve
full compatibility between 32- and 64 bit environments, they also enable 32-bit applications to
move up the performance ladder right along with other advances in technology.
AMD does not intend to force its platform suppliers, software developers, and enterprise
customers to make the tough choice between protecting their investments in 32-bit technology
and moving into the 64-bit world of the future. Instead, AMD's strategy of forward compatibility
and future performance allows customers to continue using 32-bit applications and then
seamlessly transition to 64-bit when they are ready, and hardware and software support becomes
available.
This strategy enables AMD and its platform partners to leverage the latest in 64-bit
microprocessor innovations without disrupting their current 32-bit installed base. For operating
system and application providers, development can continue uninterrupted and unburdened by
transition issues and support for the 64-bit extensions in the x86-64 technology can be provided
at their own pace. In addition, the AMD x86-64 architecture permits existing 16- and 32-bit x86
code to take full advantage of all the performance advances of new processor designs without the
overhead of software or hardware emulation.
AMD x86-64 Architecture
TM
Other Vendor's 64-Bit Solutions
Fully x86 compatible.
Instruction sets are NOT x86 compatible.
No performance sacrifice for either 32-bit or
64-bit computing
Compromises 32-bit performance. Smaller,
less sophisticated, x86 engine causes speed
penalty for legacy code. Future
development is focused on 64-bit only
performance.
Not forced to move to a new architecture.
Seamless transition based on user's
timeframe.
Forces the costly transition of many 32-bit
applications that do not require 64-bits.
Continued use of existing 32-bit
applications, tools, and knowledge base.
Doubles investment: 2 instruction sets, 2
operating environments, 2 application
binaries, 2 development and support teams.
Full support for 16-, 32-, and 64-bit
applications running concurrently.
Support for 16- and 32-bit apps only
through emulation software or hardware.
32-bit code runs unchanged. Designed to be
easy to port applications that might benefit
from 64-bit address space.
Must port 32-bit applications for full speed
execution. During transition years, must
manage 2 code bases.
