They must have seen how badly bulldozer fared against Intel's Sandybridge and realised that a new core was the only way of ever regaining competitiveness at the high end desktop and server markets.


Given how densely packed Hawaii was wrt Tahiti / Pitcairn and GK100, AMD could easily have improved packing density given that TSMC 28 HPM is well understood and mature process.
I would like to add that AMD was saved by middle east investments and their gpu division. The dire situation they put themself into with the acquisition of ATI will probably prove AMD's saviour.

And yes Jimm Keller is a great architect.

You just need to compare 15w/ 25w versions of Kabini and Beema against 15w/17w/25w of Richland and Kaveri on CPU performance to realize that AMD failed miserably with Bulldozer. at same TDP and on same 28nm process, the big cores cannot beat the small cores significantly. For Intel, Haswell crushes Baytrail at 10w. Haswell's ULV parts are in a different league compared to Baytrail-M and Baytrail-D.

I can agree that AMD needs the latest process tech to compete with Intel. But even on the same 28nm process, Jaguar/Beema embarasses Richland/Kaveri.

Bulldozer's flaws -

1. Very poor single thread performance
2. Poor cache and memory performance
3. Poor FP performance.
4. Poor perf/ sq mm and perf/watt.

AMD needs a grounds up new core to fix that. AMD should go for a low clock, high IPC design. the high clock design has failed always from a perf/watt perspective - Pentium 4 and Bulldozer
While I agree it does have the potential but Bulldozer should've been what we hope Excavator will be.
Fix the fp perf and fix the major cache flaws nobody wants L3 that makes a processor worse.

AMD overestimated the scaling and it didn't come far at all almost everything is still heavily relying on single threaded perf.


I would like to add guys that based on the geekbench the memory performance has increased by a factor 1.5 it seems. Probably needed to feed the gpu fast enough.

I don't think they knew.

Management didn't even know the correct transistor count. I hope alot of people got fired for that.

AMD engineers around that time were very open and stated to everyone that the design ethos of Bulldozer wasn't about strong single-thread, and that it was focused more on heavy parallel processing (hence the whole octocore thing.) I believe a more specific quote (paraphrased here) was along the lines that "IPC would be on-par or slightly below Stars", but of course the enthusiast community (most of it, anyway) didn't wanna believe that and instead decided to believe (literally out of nowhere, with no evidence) that it would be an "Intel killer". Intel simply has the massive advantage of having tons of R&D funds and their own fabs. No amount of magic can really turn those facts around.

I'll just leave my old sig here, it wasn't out of "nowhere", stuff like this was posted by an AMD rep repeatedly on many different forums. Heck, do you remember the Bulldozer Blog is Live thread?

I am not saying that everything is fake, the Intel fanboys are touting the numbers that make it look bad.
Why is everyone obessing about benchmarks, I think people just like to argue.

How many times do I have to tell you that bulldozer has higher IPC than our current architecture?
Is somebody being paid by intel to continually post these statements? I have never lied
The crazy rumors end up with corporate customers. I have to debunk them. There is a selfish self-interest here.

The problem was that people actually believed him, I wasn't one of those. wink.gif

As if anybody would believe that you believed that AMD did something great.

But I agree the arch they dropped needed another 3 years of refinement and therefore it was a failure.

I was rooting for Bulldozer, it had been hyped as the fastest Single & Multithreaded core in history since 2007!

Those in denials defended JF-AMD and believed him like his word was Gospel. I on the other hand saw that all the leaked benches had one thing in common, plus looking at the module structure and the way he was describing it just wasn't adding up, so I kept questioning it.

I would've loved for Bulldozer to rain on Intel's parade, and crush Sandy Bridge because we NEED the competition.

I'm sorry that I turned out to be right, and the majority of AMD fans who waited turned out to be disappointed.

I'm a realist, and call it how it is, not how I wish it was.

Maybe AMD has a ganging method for memory that can make DDR3 act like GDDR5? However I always though that was something on how the stick were configured chip wise.

Like memory on board! That's possible! However greatly limit our upgrade potential. Heck my laptop mobo has memory circuit spots on the board which confused me a bit.
