CPUID Test piece for later Intel processors.

[Siekmanski]

Dave I found your SSE3.
It moved to my PC. 

But I lost my SSSE3

[dedndave]

 

SSE3 is leaf 0000_0001, ECX bit 0
SSSE3 is leaf 0000_0001, ECX bit 9

[Adamanteus]

That's correct, but I've done exact this - so seemd you not have SSE3 and you vendor string could be duck,
in such case best is to get CPU frequency, if it's really 3000, probably something wrong in docs.
So, I've made a little changes in program  :t

Hi,

   The program from Reply #17 crashes on my P-III.
It also does not report SSE available.

Regards,

Steve

i am fairly certain that this machine supports SSE3
as many times as Jochen and i have tested it - lol

just to be sure, i wrote a simple console app to verify...

hi Adamanteus ,

your RECORD definitions are reversed: the first entry get the most significant bit/bit-range, the last the least significant bit/bit-range:

xyz RECORD bit2:1,bit1:1,bit0:1

[dedndave]

unrelated...
if you are interested in the CPUID instruction,
a couple years ago, i made this table from the ones in intel/amd docs and added some corrections

[Adamanteus]

 That's originaly was used by C-structure, and h2incx version 0.99.19 (downloaded from old forum) such translated records. Records in MASM at all not good implemented – names of fields have global scope and what bit is most significant in it not written in documentation and MASM32 Reference also.
For Signatures.zip also thanks, I can't before find AMD Modles-Stepping names, even in AMD CPUID Specification.

P.S. I changed previous archive, now I hope it works

The measured frequency is not correct, because your code assumes that the performance counter's frequency is the same on all machines.

cpu_mips PROC USES ebx

This one returns more useful values on my i5.

Vendor String = GenuineIntel
CPU String    = Intel(R) Pentium(R) 4 CPU 3.00GHz
Frequency     = 12

SSE4.2     NO
SSE4.1     NO
SSE3       YES
SSE2       YES
SSE        YES
MMX        YES

you may want to add another one for SSSE3
and - i guess "Frequency = 12" is a multiplier ?

[Adamanteus]

The measured frequency is not correct, because your code assumes that the performance counter's frequency is the same on all machines.

Yes again right, that'a algo works on old versions of Windows better on TIMERFREQSEC constant, now happend better on QueryPerformanceFrequency, so it down and works better previous version.

Hi,

   Still crashes.  Screen capture JPEG renamed to ZIP
is attached.

Steve

[dedndave]

perhaps it has something to do with how the icon is painted   :P

That's not for all versions of Windows and hardware, if you are sure that have modern one – try to reinstall Windows, could be critical updates.

[dedndave]

i doubt Steve is going to re-install windows
his machines have been tested by many programs   :P
