Advanced Micro Devices has released a presentation for investors that puts the launch of the new Steamroller micro-architecture in 2013. While the company did not unveil what chips will feature Steamroller high-performance x86 cores this year, it implied that the new generation of server-class Opteron chips will be based on Steamroller, the micro-architecture AMD puts a lot of hopes on.
more performance per watt and higher IPC? Sounds nice, but when in 2013? I just wish AMD managed to release it at or near Haswell's release date to give buyers a second option.
However, I wouldn't be surprised if it isn't. 30% is a lot and I don't think the main purpose of steamroller was to increase IPC a lot, but rather increase parallel processing. Either way, I really really wish this is true.

One of the reasons why dual-core Bulldozer modules [the same may be said about Piledriver] are not completely efficient is because they have only one instruction decoder for two ALUs and one FPU. With steamroller, AMD not only incorporated two decoders per module, but also increased instruction cache size (to lower i-cache misses by 30%), enhanced instruction pre-fetch (the number of mis-predicted branches is down by 20% compared to Bulldozer ) as well as improved max-width dispatches per thread by 25%.
More ipc through architecture improvements and a bump in clock speeds surely...I'm really interested in seeing how this will shape up.
Hopefully they don't take too long to launch like the first FX chips did, and won't disappoint like them.
Will a new line of motherboards with PCI-E 3.0 be released as well? I m on the verge of building an intel machine, but if this is in the near future I would like to hold out and wait.

I posted on couple of threads that Steamroller could deliver up to 25-30% of improvements and it seems I was right... But I was wrong about one thing, it seems that power consumption will be noticably lower while have 30% of improvements... So I think Steamroller FX 8550 on stock will beat i5 3570k and i5 4570k(haswell) at stock while it will be nearly at level of i7 3770k. Thats a rough estimation...

AMD believes that Steamroller will provide 30% improvement in ops per cycle.
Like this quote and most of the article, it seems the numbers are comparing SR to BD, not PD. So I'd not bank on seeing 30% more than PD. Gotta keep things in perspective, a tiny change in how they word things can completely change the meaning of their statement.
Plus, 30% over BD seems much more believable than 30% over PD.
I really hope they can deliver. I really do. I just wanna see them get some sort of goodness even with the budget market. At least. If this one comes out a flop then there is no hope left for AMD.
But if they release a great performer then hell. I might even forget Skyline and go for it.

I really hope AMD delivers as well, without AMD stepping their game up Intel won't even bother to add cores to their CPUs.
p.s I don't think it will be the "Skyline" as Intel Engineer have denied "Skymont" being the correct code name(December Reddit AMA) for Skylake successor, it is far more likely for that code name to be "XXXlake" instead of "SkyXXX" b/c the recent trends of ending the code name with a water related noun.
30% over Bulldozer isn't bad and should put roughly on par with K10.5 in IPC and completely destroy it in IPS. PD already destroys Phenom II. I read somewhere that there would be a deca-core processor... Should make on par with Intel's SMT quads.

The best estimates I can come up with point to SR mainly competing with IB assuming my somewhat optimistic predictions are true, sadly I think it'll be the same with AMD mainly competing at highly threaded stuff...Maybe people will realize AMD is suitable for games finally with it. (They have been for a while, I still haven't noticed what's so fast about Intel from a gaming perspective apart from a handful of extremely CPU bound, single/dual threaded games)

It's around even to ~56% slower than IvB depending on the scenario..What's more important right now (And always) is its IPS, as Haswell (And recent IB chips) can clock a lot better than previously.

There's no real benefit unless you're running CFX/SLI, even then...AMD has cheap 16x/16x so you'll have equal bandwidth to a Socket 1155/1150 setup (Unless you spend on a board with a PCIe bridge) anyway.

Keep in mind the FX-8350 is actually just BD with a few improvements, iirc the only real Piledriver chips we've actually gotten are the Trinity APUs.

They don't have much reason even if AMD is competing, as it's down purely to marketing these days. Remember, AMD was ahead or equal to Intel while being a hell of a lot cheaper for a long time (K6 to Athlon64 x2, especially once Intel started with the RDRAM thing) but still only ever got up to 30% marketshare iirc.

I wouldn't mind moving back to AMD if they if they get a nice boost per clock of 10-15%, I always prefer the underdog and I stopped playing SCII......wait I'm gonna start GW2........ maybe 20% boost? *wishful thinking but a man can dream*
Anyways, just glad things are looking up for AMD and I'm sure they'll be able to pay off their debt in a few years if things continue to go well.
