64 bit Processors
I was thinking about upgrading my machine to an AMD Athlon 64 3000+. But suddenly it struck me: do I need a 64 bit processor? What are the advantages to someone who uses VStudio, MS Office and games quite a lot? Should I stick to a 32 bit processor?
The Athlon 64 has more features than just being 64 bit (bigger register file, different cache strategy etc.), but mostly for apps that were specifically compiled for it (or .NET or java apps, if you can get a special runtime - don't know if it exists anyway).
AFAIK the Intel 64bit platform is mainly compatible with AMD's. My kernel had the option of compiling it specifically for this Intel platform but I stick to my Amd64. I could have done generically for both.

Personally I'm waiting for the dual core CPU's and even more important are silent PC's. I can do whatever I want on a 2Ghz+ PC 32bit but if I could get a something of the same power but with no noise and in micro-itx form it would be great.
Does Intel have *another* (a 3rd) 64-bit technology up their sleeve? I doubt it.
Intel's new 64-bit processors due to be released sometime in the next two weeks will run the same software as AMD64 processors. This has been common knowledge since Intel Developer Forum in February.
'Intel is "AMD compatible"' - how ironic !

So, if by the end of 2005 all AMD processors and most of Intel processors will be 64 bit, where does the compatibility issue stand? Will they be compatible with each other or will we have to use sucky emulation things? Shouldn't there be a standard instruction set?
The AMD64 and Intel's "Nocona" processors will be compatible with each other and with x86. Intel's earlier, but higher-end, Itanium uses a new instruction set.
what happened to Cyrix?
