Are "successful" CPUs, only those CPUs that beat Intel? So by that metric, Phenom II was in fact rather successful, in my mind.
Depends on what you mean by "beat Intel". AMD has consistently lost CPU market share, relinquished average selling prices (due to less the competitive CPUs). Maybe you were happy to get a Phenom II for $130-160, but that's certainly not winning. Winning is being able to successfully sell a $180-300 CPU at 40-60% profit margins. Even then, look at the majority of users - they consider AMD's CPUs to be competitive only on the low-end. Phenom II X4 is barely better than Q6600 from 2007, while the X6 is essentially an X4 with 2 of its cores unused in half the apps for most people. Not sure how that's winning tbh. On top of that, the X6 has a huge die size compared to Core 2 Duo/Quad/Lynnfield/Sandy Bridge, etc., and yet AMD is "giving these" away for $160.
I am pretty sure most of the gains in AMD's CPU market share came from Brazos and Llano platforms. By that account, Phenom I, II and Bulldozer were
all failures since none of them met their target goals of gaining back market share while returning AMD to higher profitability. With Intel's market share now 95% in servers and > 80% overall in PC microprocessors, AMD's wall is very high to climb with 3 consecutive high-end CPU generations failing. It would be one thing if AMD had small market share but extremely high profitability in those segments (like Apple in the smartphone market).
I thought that AMD's GPU strategy, was the opposite of that. That they wouldn't try to create a bigger, hotter, faster GPU than NV, rather, they would build smaller, cooler-running, and scalable GPUs, so that they could take the lead by doubling-up on their GPUs on one card for a flagship.
In theory this likely was an excellent idea, but the small die strategy clearly didn't result in a more profitable AMD as was originally thought. By pricing AMD's high-end GPUs so low ($299-379), AMD was now forced to lower the price for all other segments below that.
Recall:
X800Pro vs. 6800GT - $399: Battle of the Mid-High End
$540 X800XT PE vs. 6800U: Battle of High-End
^ Now, the "equivalent" of the X800Pro (then a mid-high end card at $399) is the HD5850 that sold for $269 and HD6950 2GB that had an MSRP of $299 but now that sells for $230-240.
Wow! Giving up so much profitability.
Now, 9800XT, X800XT/XT PE, X1800XT, X1900XT/X, X1950XT/X, were all high-end chips that sold for $500-650.
Quick Case Study from a Business (not Gamer's) Perspective: Did the Small Die Strategy Actually help ATI/AMD's GPU division to improve profitability?
9800XT ($499) = RV360/380 dies size =
210-mm^2 (best I could find)
X800XT ($499), X800XT PE ($549) =
257-260 mm^2
X1800XT ($549-599) =
263 mm^2
X1900XT ($549), X1900XTX ($649) =
314.5 mm^2
vs.
HD2900XT = performance was a let down (so no point in even discussing this card)
HD3870 = 192 mm^2 (performance was a let down, and prices had to be lowered). Die size very close to a $500 9800XT
HD4870 ($299) = 256 mm^2 (priced at almost half of X800XT/X1800XT despite similar die size!!
failed)
HD5870 ($350) = 334 mm^2 (
failed at achieving a small die)
HD6970 ($370) = 389 mm^2 (
failed at achieving a small die)
AMD's Cypress/Cayman chips are
not small by AMD's historical standards and yet were priced significantly lower.
AMD's Evergreen (HD4000) series was similar to historical die sizes, but was sold for half of what ATI would normally sell its GPUs.
So basically
ATI's small die strategy under AMD has actually resulted in:
"Larger die sizes, and lower profitability due to lower Average Selling Prices, while eroding ATI's brand value on the high-end by conditioning high-end gamers to pay $300-350 for a high-end AMD GPU, not $500-600"
If I were to take my "gamer"/"hardware enthusiast hat" off for a second and critiqued AMD's GPU small die strategy/new GPU price positioning -- they are now basically selling just as expensive to manufacture GPUs as ATI did in the past, but selling them for nearly
half the price!! I would call it a
HUGE fail.
AMD is selling 2x HD6970 (389mm^2 dies) in the form of an HD6990 for $700 today, and yet X1950XTX with a smaller die size sold for $649.
Keep this strategy up long enough and you'll be going out of business.
