You will not believe how hard AMD tries to get people to purchase its Llano and Bulldozer CPUs. Recently, on a trip to Lamington road, I found a lot of shops still having stock of Athlon II X4 but many dealers were reluctant to sell it. I would like to share some quotes from a particular shop (name withheld

):
"But the A8 has more cache! Nice integrated graphics!" (The hell I care, I was going to put a GTS 450/6750 anyway into that rig).
"Phenom? It's old, buy new architecture Bulldozer FX-4100! It is 10 times better!"
When I insisted on the Athlon/Phenom, the dealer called someone from AMD's regional center and told him the "situation": customer wants to buy Athlon/Phenom instead of APU/FX. And they had me talk to the sales person from AMD so that he himself could try and convince me why I should buy Llano and Bulldozer and not Athlon/Phenom. I told him that he shouldn't bother since AMD would get my money either way. But then I get the argument about buying "old products".
In short: They still sell it but it won't be there for long. X4 640 will cost about 4.7K. AMD itself doesn't want it's old Athlon/Phenom lines hanging about because it makes their new lines look bad (in the sense that you can get a good low cost PC running using these processors with some decent features compared to what you'd spend with Bulldozer and Llano).
Side note: I'm not sure if the guy I spoke to on the phone was really from AMD India, but it's really odd to see such things happen in the market. Anyone remember the craptastic Pentium D's that were sold all the way up to 2009 or so? The fact is that the customer will buy what he wants, for good or bad. And we want value for our money. Things like this will never do them any good to reach mindshare in enthusiasts or ordinary consumers.
I've been seeing a lot of strange things from AMD lately, and I'm not liking it. Neither are many of AMD's staff given how many are quitting lately (read the news). Dunno what's gonna happen.
