Where is 64-bit JDK for Windows Intel?

We now believe it is compatible, although we have not yet had time to test this hypothesis. Regardless, it would certainly be helpful if this was documented on the site better.

According to this Wikipedia entry (http://en.wikipedia.org/wiki/X86-64), AMD binaries are usually compatible with Intel processors. Here are some quotes:

"x86-64 is a 64-bit microprocessor architecture and corresponding instruction set; it is a superset of the Intel x86 architecture, which it natively supports. It was designed by Advanced Micro Devices (AMD), who have since renamed it AMD64. This architecture has also been adopted by Intel under the name Intel 64 (formerly known as Yamhill, Clackamas Technology (CT), IA-32e, and most recently Extended Memory 64 Technology (EM64T)).[1] This leads to the common use of the names x86-64 or x64 as more vendor-neutral terms to collectively refer to the two nearly identical implementations."

"There are a small number of differences between the two instruction sets. Compilers generally produce binaries that target both AMD64 and Intel 64, making the differences mainly of interest to compiler developers and operating system developers."

"During much of its history, AMD has developed and produced processors patterned after Intel's original designs, but in a twist of computing history, Intel found itself in the position of adopting AMD's x86-64 architecture, which AMD had created as an extension to Intel's own x86 processor line. As AMD later renamed its architecture to AMD64, Intel in turn has renamed their implementation Intel 64. It is used in newer versions of Pentium 4, Pentium D, Pentium Extreme Edition, Celeron D, Xeon, and Core 2 processors."
