Does x4 620 have sse3 capability ?

[/dev/null]

"cat /proc/cpuinfo" in Ubuntu does not list it as sse3 capable.

Wikipedia says it is...?

Yes.

It must be a bug in Ubuntu. CPUZ on Windows 7 is reporting my Athlon II 620 has SSE3 support.

 

[sirmonkey1985]

should have SSE3 and SSE4a.. ubuntu FTL..

It's not really Ubuntu's fault, more like the kernel's fault.

As I posted in your other thread, it reports sse3 just fine. sse3 shows up as 'pni' in /proc/cpuinfo on linux systems. it's short for "prescott new instructions."

Sounds like a kernel bug :-/

All Phenom II based CPUs have it.

I think the 620 is an athlon ii based cpu

no, like I just said above, your cpu is reporting sse3 just fine. in the 'flags' section of /proc/cpuinfo, do you see where it says 'pni'? That is sse3. pni=sse3. There is no bug.

Wow that is weird. You'd think this would either be fixed either in linux or in the chip itself:

fix what? there's nothing to fix! all that happened is the flag was added to the kernel before the instructions were officially named sse3. it's the exact same thing. you could probably set up some fun regex expressions if you really want it to say sse3 instead of pni.
