I'm quite baffled by the recent news that AMD is going to design server chips with licensed ARM(v8) cores compatible with their "freedom fabric" interconnect.
What I don't understand is which type of product are they after with such a combination? The freedom fabric is a storage fabric,
more like a (scalable) south-bridge equivalent. It seems AMD will integrate
the storage fabric into the (supposedly many-core) ARM-based chips? Since
AMD is not licensing the freedom fabric
to anyone else, the only "customer" of such a chip will be SeaMicro?
Since they will use licensed ARM cores, their chips likely won't compete with others (Qualcomm, Samsung, nVidia, Broadcom, ...) who
develop customized cores on power efficiency and performance. Does AMD seriously believe their processors can be more competitive based on storage technology?
is hard for me to believe that with all the possibilities in ARM based
products, AMD could only think of licensing ARM cores to sell their
freedom fabric? I thought ARM isn't even a CPU design company with the
same caliber as AMD! As someone who believe AMD took the right design
approach with their Bulldozer/Trinity (and similarly Bobcat) designs, I even doubt the licensed ARM core could compete with their own next-generation low-power x86-64 cores.
this is IMHO yet another weird plan from AMD over the past few years.
Although Rory Read assured everyone during the analyst day that AMD's problem wasn't the wrong plans , I had the feeling that it's precisely the wrong
plans, or at least lack of a right/focused plan. They planned to make
Llano based APU, Bobcat based APU, Bulldozer and Trinity, all in a narrow
2-year window, during which they will also revamp graphics core and
spend $370M to buy storage technologies. If they were trying to do
everything of course one of the things they tried might fare better
than others, right? Now they are trying to make ARM based processors, but just for scalable storage. I really don't understand--what would that accomplish which their x86-64 expertise will not? If ARM really is
lower-power than x86 at the same performance (which I seriously doubt),
then hasn't AMD been wasting time & money in designing Bobcat, but
instead should've licensed ARMv7 cores 2 years ago?
Their problem was not having the wrong plan? Ba!!!
