AMD is moving to 28 nm years after intel has reached 22 nm.
So anything that has to perform it's over of course.
Add to that we see how Indian engineering works - using 2 billion
something intel did do 3 years earlier in the same proces
technology using far under 1 billion.
The mobile market is very competative with many players. Not just
intel and AMD. Price matters a lot there.
Intel when having same quality engineers would easily beat AMD there.
22 nm versus 28 nm. It's not a contest.
It's game over normally spoken. Yet for mobile market a lot is
possible it's a competative market.
As for 4 socket servers - their roadmap basically shows the same
cpu's like they have now. They can clock it maybe
a tad higher win 1% here, win 1% there. That's about it.
So AMD doesn't compete on number of cores. So they can't be on par
with intel 2 socket machines basically
if this roadmap presents reality.
Basically AMD just mastered 32 nm, 3 years after intel released cpu's
for it. Just in order to get bulldozer on par with i7-965
from years ago, if we speak about integers, they needed to have
bulldozer consume A LOT more power.
If their new design team is so bad in producing equipment that can
use little power, how do you guess they can compete
in an older proces technology against matured intel 22 nm products in
the 'highend' mobile market?
CPU wise they're total history. Moving your R&D to 3d world has
become a total disaster for AMD.
It's that their gpu line is doing well, but let's ask around a bit -
how many run gpgpu on AMD gpu's in opencl?
They're not supporting their opencl very well, to say polite. I can
give examples if you're interested.
Yet most important point to make there is that one of the biggest
competative aspects of AMD was getting a lot of CPU cores
for a cheap price. Those days are definitely over.
I don't see how their design team even remotely has any clue about
building low power products the coming years,
if we see the massive mess ups. Basically AMD has 1 great chip from a
few years ago still playing in the market place,
if we speak about the cpu division.
It won't be long until everyone has forgotten about that as well.
As for crunching,which is what most people do on this list, the AMD
cpu's aren't interesting anymore.
Sure their GPU's are for the floating point guys (not for integers as
they support opencl not very well - so not all hardware instructions,
some crucial ones - are available in openCL of that gpu, which is a
major reason to choose for Nvidia if you have to do integer crunching).
But one very big division called CPU sales, forget it. They have a
Seems they get some sort of Asian company now if we also study the
code names very well, which just can deliver crap cpu's for a cheap
cpu's eating too much power for western standards.
Forget low power design in India - wont' happen.
