You compared x64 with x32 one
What older x32 build says?

No, not the same, look at reported freqs
both new and old builds disagree with x64 one

yes, this feature looks broken and better to remove it in new rebuild.

Feature detection in the Lunatics builds is mostly based on Microsoft example code for using the intrinsic __cpuid() function, see e.g. http://msdn.microsoft.com/en-us/library/hskdteyh(v=VS.80).aspx. Speed detection is added using rdtsc, IIRC.

As has been noted, that's basically cosmetic for now. If we ever get around to using some of that information to choose paths within the processing, it will be necessary to try to make it accurate and keep it up to date.

I noticed the same info on the I7-2600, HTT turned on, displays 4 cores. These are Bêta builds!

The x86-64 SSSE3 optimized app., displays correct info on the I7-2600 :

But, as you already stated, it's cosmetic and in this case different from
NON-ATI apps, but it is a QUAD-Core with HTT. (Turned on, it also doesn't
notice the L3 cache, on this CPU, haven't seen any notice of L3 on BOINC either).

The Core i7-2600 processor has 64 KB L1 cache memory per core, 256 KB L2 cache memory per core and an 8 MB L3 Advanced Smart Cache ...

But, IMHO, that's what Bêta-testing/tuning, also is for, spotting inregulaireties and other things, that could be improved ;-)
B.t.w. I'm very glad with both rev.177 (& rev.365 bêta) and rev.521 for AstroPulse, on ATI GPUs.

And shouldn't BOINC display exact CPUID info?
