Intel Reverse-Engineered AMD64

Posted by: Newsfactory on: 04/06/2004 03:44 PM [ Print | 6 comment(s) ] · 3544 views

Just spotted this bit of Info over at ExtremeTech!

After investigating the instruction sets used by 64-bit chips from AMD and Intel, an industry analyst has concluded that Intel reverse-engineered the AMD64 instruction set to create its own 64-bit microprocessor architecture.



Tom Halfhill, an analyst at In-Stat/MDR in San Jose, said Monday that he had compared the instruction sets of AMD's 64-bit chips, called AMD64, with the 64-bit extensions to be used in the Intel Xeon processor and future desktop chips. The smoking gun, Halfhill said, was Intel's choice to mimic a decision AMD made in its early Opteron designs, and later reversed.

"Intel reverse-engineered the AMD64 instruction set to create its own 64-bit microprocessor architecture."

Are you stupid? AMD doesn't own any of their "64-bit" technology. It is all property of Intel - the owners of x86. Intel copied NOTHING.

That's not correct. AMD was given free use of Intel's stuff in a cross licensing agreement some years back. AMD took this stuff, added some of it's own stuff to it and extended it to 64-bits. It's now different enough that AMD can say it's their own. The irony of it all is that due to the cross licensing agreement, Intel can use it without paying royalties. However, if Intel should add a memory controller to their CPU, that might change...

Well this news is wrong, since Intel and AMD have a technology exchange agreement (don't know the exact term), that's also why AMD can use SSE and SSE2.

NO...you are stupid! Your statement makes no sense? Why would Intel reverse engineer what it "supposedly" already owns then?

Couple that with what others have said, I suggest you remove foot from mouth.
