    Can .. I wrote 'can have' .. Anyway a leaked Linux patch on LKML.org, first spotted by The New Citavia Blog, suggests that AMD Zen based processors will feature up to 32 physical cores. The patch a...

    Will be nice AMD really need a big win against Intel ........... Let's hope 32 zen cores have really good performance and not just lots of cores

    I know more cores are fun and all, but even in 2016 PC consumers still prefer higher performance per core, rather than core count. (Thank you lazy developers)
    The core count worries me a bit, but I hope it's only for future extensions.

    If performance per core won't come up close to Skylake, we facing yet another Bulldozer.

    We'll get 4 and 8 cores for desktops. Servers are ones getting more cores while running lower voltage & clock to have greater power efficiency.

    With 1st DX12 test I did realize that 8-core CPU will optimal as one needs some threads for game itself. With Vukan it will matter little if CPU has 4 or 8 cores as that drastically reduces need for CPU power.
    And you mistake apple for potato. Total performance of 8 core Bulldozer was around total performance of 4 Core i5.
    That was 1/2 IPC on AMD side and no performance bonus in total.

    Now, you will see performance equivalent to 80~90% of intel's chips per core while having 8 cores / 16 threads.
    So even if AMD may lag behind in single threaded performance, they'll get total CPU performance win.

    That's why I expect 6-core i5 soon.

    Was just going to post this! :nerd: Just because some version are going to have 32 cores doesn't mean every chip will have that many! Pretty sure AMD are just planning for the future.

    Shame PC i plagued with Console Ports that only support 1 or 2 cores.

    Well if it's true and AMD can indeed catch up to 80-90% of Intel's CPUs, only selling cheaper will really get at Intel's market share for gamers. And that's only if devs aren't lazy and really give us games that make use of more than four cores regularly, not only AoS... and I hope AMD does make good money of maybe relatively cheap priced CPUs (even though they had serious R&D costs).

    Better late than never, I guess. If Zen is really successful, that might actually happen. Though I wouldn't be holding my breath. Making a 6-core is slightly more expensive for Intel and if Zen can put up a good fight, Intel can't as easily raise their prices. The Intel execs would sooner cut their own stomachs than cut their profit margins.

    What AMD needs to do right this time, is to understand their products which are currently on market.
    See exactly which will become obsolete by their own newer chips, when those chips are going to be available. What is current stock, how many they sell each month, how many are in market chain and time properly moment when they'll no longer manufacture those old chips.
    As part of their financial loss is trashing unsold chips.

    I personally think that we won't see i5 hexacores before 2018. Everything that comes out this year is already fixed and under production I'd say, 2017 will be in the works and fixed before Zen will hit the streets. Maybe I see it too pesimistically, but as chip making isn't a business that happens in the spring time when they want to launch in fall, I don't expect them to instantly counter anything zen might put AMD ahead with.

    Well, intel can count cores, multiply values. I think they can guess where those chips will be. They know for very long time that Zen will have 8 core variant, and +-40% higher IPC over Excavator.
    I can guess myself as I did.

    Maybe you're right. Which gives them an educated guess, but no real numbers still. Not sure they want to see and wait if AMD delivers or does not... I wouldn't make my business plan solely on the guess if AMD does another Bulldozer or not. And they certainly don't want to give us a cheap hexacore if they'd not be threatened by AMD.

    So the question is, does Intel feel threatened? I don't think so.

    That's a nice core count right there.

    AMD has had some high core counts in the past too.

    I am probably not going to spell it right, but magny cores had a ton load of them. :D

    Magny-Cours? They're more about curcuits than cores I think :D

    All AMD need to do is match intel performance per hz and add two more cores and it´ll sell like cupcakes!! :nerd:

    What are you talking about?

    Both consoles at least give access to 5-6 cores for games.

    Which is weird considering Wii U is 3 core, rest of the consoles use 7 out of 8 for gaming. Well one day. One fine day they will add rudimentary multicore support at least.

    I would still prefer 4-8 very fast cores vs 32 super slow cores. Multicore support is still lacking and i am afraid that Intel will still come on top when Zen arrives.

    Like someone above said, 6 core i5's would be a best thing.
