as long as the old software still works via older x86/86_64 emulation then cool this could be neat. but itanium was supposed to be 64bit only and emulate x86 too and we all know how that turned out. not to mention intels other failed attempts at killing x86
It was inevitable and I’m surprised it’s taken this long to get traction.
I wonder why they’d bother if it doesn’t actually make a performance difference…
This is not done for performance, but it makes a difference in terms of cost; reduced validation times/effort.
The cores will be the mainly full x86 still, as backwards compatibility is basically free at this point in terms of power and silicon budget. But this opens the door for vendors to only support 64-bit EFI configurations.
The only selling point of x86 is backward compatibility. Remove that and you might as well move to a newer, better ISA.
I mean, that’s literally the main selling point of a processor; being able to execute a software library.
“Getting traction” would be AMD adopting it, and hardware from both AMD and Intel reaching consumers, as well as support in all major operating systems.
All we have right now is a spec. No hardware and no declarations of intent from anyone else than Intel.
All we have right now is a spec.
That’s how it needs to start. Amd doesn’t even need to adopt this since the spec is still compatible afaik. It just will enable Intel to produce cleaner designs. Also, this is 6 month old news.
64-bit Only Architecture
X86-S
Should have called it x64-S.
X64-Gen2-64*64
Holy shit dude I thought somebody quoted me by name.
So “formally” x86-64-S? How’s that any better?
So… x86-S architecture are open source -d, made its license usage similar to arm, or what?. I’m confused.
You still need patent licenses for a ton of x86/x64 stuff.
Something being open source can still mean it’s nearly unusable (legally!) due to patents, see x264 and x265.
“Ex Eighty Six Ess”. How about a name that doesn’t sound so swishy when spoken?
Ooh, I’ve got an idea. How about X64?
I don’t find it hard to say that, not really that much different from x86-64 “Ex Eighty Six Sixty Four”
X64-S would be a cool name
could you make a new isa loosely based on x64, but new and modern so x64 run normal but no x86 support only emulation
