    This is a trusted source it shows the right CPU in the socket

    That number 8 means 8 cores so is this a mysterious Phenom II 8 core going around highly doubt it

    All benchmarks of Bulldozer for trusted sources that are using engineer samples are not final performance of what the consumer(us) will get if we buy a Bulldozer

    Performance from these engineer samples to consumer samples only goes up

    The Engineer Samples performance is fact not fiction, it that it's not tweaked for consumer or brute force benchmarks

    Speculation: There will be a performance increase from this B1 Sample to the B2 Sample...where B2 is the sample we the consumers will get if we bought a K15h CPU

    B1 to B2 will have tweaks, a more higher quality silicon fabrication as they aren't going for high yields anymore(yield quality goes up)

    Then later this year near November->December we will see C0 stepping
    Which will have better tweaks, more overclocking headroom, higher stock clocks

    /facepalm You don't need to say it three times yeesh

    seronx and deltatux are my favorite users on this forum. Fire and water.

    I really love bulldozer performance, thanks for sharing seronx. What I also would love to see, is bulldozer getting higher fps in games. I guess games have to support all 8 cores to make full use of it. However would love to know more about performance per core...

    I still say I'll wait until I see them with reviewing sites that can be verifiable before I believe the numbers.

    Games will love that 2 cores are on 1 part of the cpu

    [​IMG]

    If you can read this you can see on the silicon that core 0 and core 1 are right smack together

    So games that are dual-core will absolutely love the Zambezi processor

    But, if the game is just single-core expect a lower performance but how they explained what a single core would do...It doesn't seem like it would lower performance


    Performance per Core 0 on each Zambezi Module should be equivalent to i5 2500K(In theory only, Realistically there is going to be variation how much no one knows till Reviewers test Single Core performance or someone leaks single core performance(With a production sample))
    But once Core 1 on each Zambezi Module becomes active the performance should be equal to greater than i7 2600K

    Core 0 only active means that it has ability to use all the resources

    With Core 1 active the resources get halved but throughput doubles to almost triples

    Essentially, back it up or pack it up. I agree.

    small correction games that are single threaded will benefit even more (this core yea acts as a dual core in single threaded apps).
    Remember back when i said 2x128bit (SSE) and X3 terran conflict space game?

    Ya that is in part with Core 0 being able to use all resources

    1 x86-64 execution and 2x128 bit SSE executions
    +
    2MB L2

    But how it will play out is totally dependent on what scores it gets in single threaded apps

    You can't use software backwards compatibility to justify physical architectural backwards compatibility. If software devs broke compatibility, they'd see the financial effects almost immediately. Breaking compatibility at the hardware level (ie, changing sockets) doesn't result in any financial loss for Intel or AMD. Maintaining a socket for too long will however, result in financial losses. AMD wants/needs to gain market share from Intel. To do so, they have to innovate.

    AM3+ -> FMx(Mostly likely FM2)

    And last time I checked FM is a pin shrink from AM

    Less Silicon = Cheaper CPUs

    Bulldozer based processors are supposedly backwards compatible with the AM3 socket....which means the physical package can't be any smaller. So, exactly what was the point of your post?

    I'm saying the architecture designs themselves rely on backwards compatibility lol. The sockets don't really provide that much innovations tbh. There really wasn't much difference between LGA1156 and LGA 1155 to warrant a new socket. They should have gotten people to use the same socket or planned ahead of time tbh.

    Zambezi based processors are built for the AM3+ Socket
    Valencia based processors are built for the C32 Socket
    Interlagos based processors are built for the G34 Socket

    Zambezi/Valencia/Interlagos are all based on the Bulldozer architecture

    Zambezi is AM3+

    Zambezi needs the AM3+ Socket Architecture to function properly

    Komodo is FMx

    Zambezi AM3+ (2011) -> Komodo FMx (2012)

    Valencia C32 (2011) -> Sepang C2012 (2012)

    Interlagos G34 (2011) -> Terramar G2012 (2012)

    There is your socket change.

    You requested one there it is...
    Because we are so late in this thread:

    Zambezi is the Gamer-Enthusiast Desktop CPU Line
    Valencia is the Entry-Level Server CPU Line
    Interlagos is the High-End Server CPU Line

    Komodo/Sepang/Terramar are all based on the Enhanced Bulldozer architecture

    Fitting AM3+ CPUs to AM3 boards aren't officially supported by AMD, so they're technically weren't design for backwards compatibility to AM3 boards. That "function" is just board manufacturers wanting to do that and have engineered a way to make AM3+ chips work on AM3 motherboards.

    AMD has said since the beginning of the AM3+ announcement that Bulldozer is not going to be supported on AM3.

    the fact that they still use a single threaded app like superPI just makes me lol. thats stupid. use something multi threaded like wPrime instead.

    You make pointless comments about why someone joins a forum as well, lol.

    No wonder, it was a terrible comparison to make, when everyone knows games are GPU limited at that resolution.
