Seems like it...If they are making an ARM based server CPU that seems a bit more promising though, lots of companies are shifting to low power but highly scalable systems rather than big powerful ones.
I'd say they probably fixed the x86 decoder. When I first saw the Bulldozer architecture, I thought that decoder (4 instructions per clock cycle) looked a bit underpowered to supply 2 full integer cores and a shared FP unit. I really believe that's what's holding back Bulldozer.
I Agree with you. the decoder does seem to be quite under powered..! Also there has been lots of talk about the loooooooooong pipeline Bulldozer has..!
the changes could be there as well..! Though that would mean tinkering with the architecture to some extent, but hey, we are currently speculating, aren't we..?
AMD is still going to manufacture thier high end MPU in 2012 using 32nm SHP SOI process? So is GF really not investing in 28nm or 22nm SHP process in 2012 and even early 2013? IF so AMD is screwed on the high end....
Where AMD wins on the server side of things is price / performance. For 2S systems, motherboards are about the same price, but a 16-core Opteron 6272 costs half as much as the cheapest upcoming 8-core e5 Xeons. In 4S systems, the difference is even greater; with a $400 12-core Opteron squaring up against a $4000 10-core e7 Xeon.
At work we've just added 5 48-core Opteron servers to our existing 6 32-core Opteron boxes. Equivalent Intel systems would have cost about twice as much, even though the memory and disks are all the same.
You forgot to add that HT(Virtual Cores) is kinda "bad" in the server market. And sometimes having more cores in lower clock is better than less high clock cores not only in servers, but I mean in graphic design.
