Q0941

[hugo929]

It looks strange to me. any one can confirm it is fake or not?

It looks genuine to me but a better picture could help.

This one is an A1 Step ES with WW10'96 date code. A1 ES were produced between WW10 and ~WW20'96, so it's consistent. A3 Step ES (Q061) where from WW30-40'96. Z plant code is common on Q0941.

what does ATD mean? thanks

[hugo929]

and how about the following two Q140?

[xsecret]

Fake Q140 were mass-produced and 90% of the ones I looked at were fake. It's almost impossible to tell without a good quality scan of the chip.

ATD is probably related to the Assembly Technology Development group at Intel (Chandler). They worked on thermal dissipation and new package materials.

EDIT : Both looks clearly fake to me. Lack of "ES" on the first one and lack of "V" on the second one.
