Your best bet is to purchase it from a reputable on-line retailer who
clearly identifies which one it is.
You can go to the NewEgg.com site and see close up pics of the OEM versions
that reveal the difference.
There is an excellent review here:

Where I buy (here in Denmark) they have the codes on the order side
like:
ADA3200BIBOX ... the BI part shows it's a Winchester
ADA3500AWBOX ... the AW part shows it's a Newcastle
ADA3200BPBOX ... the BP part shows it's a Venice
Each has a different price with the BP (Venice) being more expensive
than the others.

Agreed. I'd buy from newegg.com. If you don't, please note the price
differential. You'll pay a US$50-70 premium for the Venice-core
version. Anyone who tells you he'll sell you a "Venice" CPU for the
same price as a "Winchester" probably doesn't know what he's talking
about and is not to be trusted to deliver the CPU you're looking for.
