    Bulldozer:
    First retail x86 processor to breach 4.0 GHz stock
    First retail x86 processor to breach 8.0 GHz with 4 cores
    First retail x86 processor to breach 8.5 GHz with 2 cores
    more etc.

    Changes with Piledriver:
    Use of Resonant Clock Mesh to reduce clock mesh power usage by 24%
    Improved Fetch, Decode, Schedular logic to improve bandwidth deficiencies
    Certain units functionality has been restored resulting in a 2x increase in bandwidth for special units
    more etc.

    Changes with Steamroller:
    Dedicated decode for each core and macro-ops cache that can bypass the decode stage pipeline.
    Streamlined and improved Floating Point Unit.
    More Improved Fetch, Decode, Schedular logic to improve bandwidth deficiencies.
    more etc.

    Changes with Excavator:
    High Density Cell Libaries to reduce size of the processor by 30% and decrease operation power consumption by 15-30% while on the same node as Steamroller.
    more etc.
     
    Performance Improvement -> Power Improvement -> Performance Improvement -> Power Improvement seems to be the tick tock cycle with the 15h family of architectures.

    It sounds good enough...  Now if only they can release it before 4 years pass again, they might have something that resembles competition.

    Three
    2008(intended 45-nm tape out) -> 2009(intended release on 45-nm) -> 2010(GloFo finish 32-nm, AMD tapes out Bulldozer) -> 2011(AMD launches Bulldozer)
     
    And, if you go back far enough you would notice Phenom II FX in marketing slides for AMD 2009 before 10.5h came, guess what processor that was going to be.  (Implying 45-nm Sandtiger was already taped out).
     
    2009-2011 is a three year distance.

    Whenever they begin to compete with Intel in the high end market then I'll start looking into what they can offer. They can't compete with intel's sandy bridge CPU's still, much less Ivy Bridge high end and anything that goes into an LGA 2011 socket. They make great APU's but their high end CPU's have been lacking for quite some time, in comparison with Intel's high end processors. They badly need to get this one right, if anything just to keep Intel on their toes

    Honestly, you got to give them some credit, they are 5% of Intel's workforce size yet maintain 15% of the x86 market.  Of course, that's an example of a glass-half-full argument.
     
    To be quite frank, just because AMD hasn't been competing with Intel's high-end doesn't mean they aren't competing at all; why else did Intel break tradition in debuting high-end first and instead introduced Sandy Bridge with the mainstream P67/H67 chipsets?  Simple: At the time Fusion was the unknown threat to Intel's previous generation P55/H55 Lynnfield and Clarkdales since AMD was pushing it ahead of the Zambezi FX parts, and the Llano constant delays was their advantage.  Intel simply responded in kind with their one-step-ahead strategy.
     
    Had instead Intel replaced X58 with X79 first and left P67/H67 to another quarter or year, Intel would have only been replacing their own chipset sales that could have been milked further with no high-end competition while AMD would have had a real chance at gaining shares in mainstream segment.
     
    It is entirely possible Intel expected more from Bulldozer too, i.e. one reason why Intel debuted 2700K at all months afterwards as if it was scheduled before Bulldozer's debut.  In the past new AMD debuts led to Intel price drops to compete, not faster and more expensive SKUs.  Although the postponement of 3820 looked like 2700K became something to milk.
     
    AMD is the same reason Sandy/Ivy came before their -E variants; one dead give away is their price, we can't just pair up flagship with flagship since the price gap is bigger than the performance gap.

    AMD needs more marketing, I think that is the sole trouble.  Most folks I [used to] know have never heard of AMD, they think Intel is inside everything and take it for granted.

    For Intel processors, 0.122 x TDP = Continuous Amps at 12v [source].

    Well, Multicluster Multithreading is an Intel made theory but Intel couldn't use because the core and floating point unit is fused.  At the time only AMD continued keeping the core and floating point unit seperate.  So, AMD is using Intel engineers and Intel designs to beat Intel with designs considered to be a failure or to risky to get in production or, required a lot of work in redesigning of the core they would be using for 6 years.  Intel is indeed inside everything and people don't realize it sometimes.  ARM wouldn't have existed if Intel didn't start making ARM processors for a short period of time.
    ---
    Main reason why Sandtiger didn't release in 2009 is quite simple. 
     
    32-nm is 2.1x more compressed than 45-nm.  316 mm² * 2.1 => 663.6 mm².  Yes, Sandtiger & Orochi are the same design.
     
    Nehalem: 265 mm² (775m transistors)
    Sandtiger: 664 mm² (1.3b transistors)
    vs
    Sandy Bridge: 294 mm² (1.27b transistors)
    Orochi: 316 mm² (1.3b transistors)
     
    2.51x -> 1.075x

    I'm not talking about server processors here, we can get into a whole different discussion if we want to start getting into Xeon against Opteron. I used to have a server with two Opteron's and I really liked it as a server set up, let's keep with the gaming/high performance segment. The FX-8150 is what around $180, and you can get a 2500K for about $210 these days? For $30, I'd say you are getting a pretty nice bump in performance overall, not in the two or three things that FX comes out on top in, overall performance. Let's face it, Steamroller was a total failure at launch and is still unoptimized to this day. And that 8150 is supposed to be their top end gaming CPU, and it can barely compete with a mid range Intel processor. Im not saying they aren't competing, they are dominating the APU market, and have a ton of OEM contracts. But they are not competing very well in the high end (gaming) segment at all, of course they are going to sell FX CPU's, there are the people who stand by AMD and wouldn't purchase an Intel CPU if their lives depended on it. But for anyone that is looking for a good performer, the nod goes to Intel, and it has for the past few generation in this market segment. We can throw die sizes and transistor counts around all we want, but at the end of the day and the bottom line, Intel is giving it to AMD. I want nothing more than for AMD to start releasing good CPU's that will compete with Intel for the enthusiast dollar, Intel needs that kind of competition so they can keep releasing better CPU's and their prices don't get more inflated.

    There was a point when AMD chips were doing better than intel for a considerable amount of time. Back when intel had the pentium 4 prescott cores and amd had the athlon 64 fx. The price for a 64 fx was just mind blowing at the time. It was about $1000. And it's since the Intel Core duo family came out that amd starting slashing their prices to keep up. Ever since then they've been playing catch-up, and their selling point to today is still bang for buck.

     I'm going to throw two wrenches in this wheel, if you don't mind:
    What AMD stated in May 2012
    What AMD stated in Oct 2011
     

    Thank you sir as i read that news, but could not find it.
     
    Now ignoring the AMD fanboy, Intel actually has the best for the price. The 2500k is $159.99
    (http://www.microcenter.com/search/search_results.aspx?N=4294966995&NTX=&NTT=&NTK=all&sortby=pricehigh)
    Now AMD's top and only CPU that can compete is the FX 8150 which is $179.99.
    The only thing that the FX 8150 can beat the 2500k in is video editing.
     
    Any application that uses 4 cores or less (Which is about everyone out there) will run better on a 2500k as it has strong cores.
    http://www.hardwaresecrets.com/article/AMD-FX-8150-vs-Core-i5-2500K-and-Core-i7-2600K-CPU-Review/1402/1
     
    Now for budget builds, depending on what the person wants. I would consider a AMD cpu (Usually in a bundle, like here:
    http://www.microcenter.com/site/products/amd_bundles.aspx)
    But thats usually for people looking for Video editing. Even then, i would consider a Intel first. 
     
    Now after the above rant, The new processors by AMD are coming way to slowly. 3-4 years is to long.

    You know that he is not an AMD fanboy dont you?
    The irony is he quoted my attempt to show that AMD is being hypocritical because they made claims that can be interpreted to run in opposite of this recent leaked slide.  But rather than acknowledge or agree, due to his bias' and inability to be objective or logical, he didn't see it [that way].  Also because I bothered saying nice things about AMD, it makes me a fanboy.  It is cute, but the conclusion lacks vital information: My habits.
     
    I've never owned AMD and since the majority of games I play regularly are all CPU-intensive and single-threaded, Intel has thus far won no contest-- but few fellow members ask me anything about my habits and I rarely mention.  Afterall, the point for objectivity is to either not take sides or not make your choices part of the conversation-- the latter is more practical, so I don't see how what I say about AMD has anything to do with my choices or stances.

    We really need AMD to get back in shape to fight Intel, otherwise Intel will just ask a fortune for their CPUs

    I broke my cpu up and sold it not too long ago.  In the next 6 to 12 months I will be building me a budget gaming cpu and I would love to try a new "cheap" AMD cpu.  If it's anything like today where the dual core I3 at 100 bucks beats most lower end AMD Processors specifically the 4100 series i will be using intel again. The only problem is I fear that if new consoles come out next year that a dual core budget gaming machine won't suffice as I am expecting the next generation of games to utilize 4 cores or more so buying a dual core will be a waste.  So I hope AMD cam make a decent 4 core cpu that handles games just fine for around $125 and if they do I am on board.  Will still only use Nvidia graphics cause EVGA only makes Nvidia and I have always used EVGA for graphics cards and always will until they give me a reason not too which if it hasn't happened since the 9800 series it won't.

    Well, there is a Trinity unlocked dual-core "A6-5400K" coming at around $75, it should be interesting how/if Intel reacts to it.  It was once rumored Intel would have made an unlocked Core i3 model at an MSRP of $150, but it was cancelled given how the competition had an FX-2150 that never materialized.
     
    AMD's Zambezi Bulldozers overclock well only when the cores are disabled, so one has to wonder about Piledriver, Steamroller, etc with less cores.  Granted Intel would have taught us all to accept more cores in the future, while AMD survives by catering to their own niche.

    Re:AMD Unveils First Details About Steamroller 2012/09/15 18:16:27 (permalink)
    All my speculation...
     
    Steamroller + Viperfish
    10 cores/5 modules
    288 bit DDR4 w/ ECC(4 x 72 bit ECC) (Quad-lane ECC DDR4)
    Northbridge has the same clockrate as the cores
    4 * Hypertransport 4.0 16 GT/s links
    52/42 * PCI-e 3.0 Links
     
    Totals
    L1i Cache => 128 KBytes
    Instruction Fetch = 64 Bytes
    Instruction Pick Buffer(per core) = 256 Bytes
    Instruction Decode = 64 Bytes per core
    Instruction Dispatch = 64 Bytes per core
    Instruction uCache = 8 x 16 Bytes per core?
    Execution Core = 4 Micro-ops per clock per core(4 Macro-ops)
    Floating Point Unit = 4 Micro-ops per core per clock(4 Macro-ops)
    Retire Rate = 8 Macro-ops
    L2 partions => 5 MB(LP)/1 MB partition per module, 10 MB(HPL)/2*1 MB partitions per module, 20 MB(HP)/4*1  MB partitions per module.
     
    Each core has 4 AGLUs, 2 that deal with stores and 2 that deal with loads.
    The Floating Point unit is the same as Bulldozer with modifications:
    2 * 128-bit FMAC / FP FMA/MUL/ADDs + INT FMA/MUL + Conversions
    1 * 256-bit ALU / INT ADD + XBR + FSTORE
    FSTORE => 4 x 128 bit loads / 2 x 128 bit stores
     
    Vertically Symmetrical Multithreading = XMT
    Vertical Multithreading = VMT
    Simultaneous Multithreading = SMT
     
    XMT Units:
    Pick
    Decode
    Dispatch
    Cores
    Retire
    L1d

    VMT Units:
    Fetch
    Prefetch
    Misc
     
    SMT Units:
    FPU
     
    Back to the Floating Point unit:
    You either do 256 bit FMA or 256 bit MUL + 256 bit ADD for integer.
    You either do 256 bit FMA or 256 bit MUL or 256 bit ADD for floating point.
     
    SKUs:
    10 cores, 5 - 20 MB, 3.0 GHz -> 3.4 GHz stock + 0.4 GHz turbo all core
    8 cores, 4 - 16 MB, 3.2 GHz -> 3.6 GHz stock + 0.4 GHz turbo all core
    6 cores, 3 - 12 MB, 3.4 GHz -> 3.8 GHz stock + 0.4 GHz turbo all core
     
    L2 latency
    one partition = 15 cycles? 1 MB
    two partitions = 30 cycles? 2 MB
    four partitions = 60 cycles? 4 MB
     
    The L2 cache is shared with all cores and contains both data and instructions.  Steamroller = Big Jaguar/Jaguar = Little Jaguar
