thanks Guga   :t

nice one - like Gunthers   :P

Dave,

thanks Guga   :t

I think Sinsi has a similar one. You should upgrade.

i would love to have an i7 or i9 (or whatever i they're up to)   :P
i would also like to have dual-boot win7-32 and win7-64
alas, you can't buy windows 7 anymore   :(

You can't change the company policy of MS. But let me say Windows 8.1 isn't so bad. Your 32-bit OS depends on the size of your HD.

Always forget what I have.. not even sure whether this is good any more ?

Hi K_F,

could you test if your CPU supports AVX, please? You'll find the test procedure here.

i'd say it's one of the best   :t
haven't really been keeping up with the latest processors, though

;model 1, 2, 3             ->  Intel Pentium (I)
;model 4                   ->  Intel Pentium (I) MMX
;
;family 6:
;model 1                   ->  Intel Pentium Pro

;L2 cache not 0, 1M, 2M    ->  Intel Pentium II

;model 7:
;L2 cache = 512K           ->  Intel Pentium III (or Xeon)
;L2 cache = 1M or 2M       ->  Intel Pentium III Xeon
;L2 cache not 512K, 1M, 2M ->  Intel Pentium III
;model 8:
;brand ID = 1              ->  Intel Celeron (Pentium III)
;brand ID = 2              ->  Intel Pentium III
;brand ID = 3              ->  Intel Pentium III Xeon
;
;leaf 0_1 EBX bits 7-0 = brand ID
;leaf 0_2 cache descriptors:
;  EAX 7-0 indicates iteration count
;  The other 15 bytes of EAX, EBX, ECX, EDX each represent a cache descriptor.
;  If the high bit of any byte is 0, it is a valid descriptor byte.
;  For family 6, model 5 and 7 CPU's, the iteration count will be 1
;  and the L2 cache descriptor is probably in EDX, bits 7-0 (verification needed):
;    40h = no L2 cache, 41h = 128K, 42h = 256K, 43h = 512K, 44h = 1M, 45h = 2M

i am still trying to verify that the L2 cache descriptor is in DL for family 6, models 5 and 7
otherwise, we have a pretty good name list

Hi K_F,

this is what I get..

Thank you for the information. Excellent processor.  :t
