    speaking as a guy that watches the live stream it is kinda annoying seeing these "New Videos" when hey are really just snippets from the previous stream but that is just my opinion .

    so you speculate about a topic that AMD has already provided us with information on… AND GET IT WRONG?!
    is googling really that hard?

    amazing

    Lol… The nerds speculating without any research… Are you actually nerds or is it just for the views?

    Zen2 is 7nm. It's right on amd's Zen roadmap LOL.

    I wish you guys did more research on the products you discuss. ZEN 2 definitely has been confirmed by Dr. Lisa Su to be tapped out on 7nm

    It won't be going to 7nm until approximately 2020 (ZEN 3) when DDR5 is expected to be utilized as well.

    Gordon, did you take the snap on screw driver when you left maximum pc?

    Intel has the best manufacturing yet AMD is still more efficient.

    You will see everyone Zen 2 in 7 nm will has POWER.300points SINGLE TREAD that in CB.

    Nope Global Foundries "7nm" which yes is semi comparably to Intel's 10nm when you account for logic and SRAM density is coming for Zen 2 but Zen 2 isn't coming until 2019, Zen 3 will be produced on a improved 7nm process done on EUV while there first "7nm" will be done on DUV.

    Also I can confidently state that AMD will offer upto 12 cores on there mainstream platform due to them saying that that will be doing a 48 core server chip for Zen 2 which for multiple technical reasons you would not be able to do that on the same chipset as Naples, and changing chipsets and sockets within a generation is even more taboo than it is in the mainstream. So if they do it, they will do it by increasing the number of cores per die, which it only makes sense that they would use the same dies for the mainstream aswell because then there is no point in a MCM CPU as most the cost savings actually come from not having to design a new die for Server, HEDT and Mainstream, and being able to save all you best dies for your server / HEDT CPU's.

    It would litterally make no sense just to make a die for 2 – 3 products, and especially now Intel is rumoured to have a 8 core 16 thread CPU incoming, if AMD doesn't want to be relegated back to being the cheap option they needed this anyway as they are unlikely to be able to completely catch Intel in clock rates and IPC but I think they will get very close, so they need something extra up there sleeve which 50% more cores would do it, but they wont price there 12 core at the same price as Intel's 8 core CPU, the 12 core will be competition for Intel's Skylake X line and lowend "Cannonlake X" line.

    Also remember AMD's AM4 socket is rated for upto 140W so they can easily push upto 110 – 120W on there 12 core and still be well within spec and furthermore be more power efficient than the Skylake X competition as well probably being as power efficent as Intel's "Cannonlake X" lowend CPU's. Ontop of that Global Foundries has there "7nm" node being able to deliver a 60% power reduction so it will only be for pushing clocks that they will need the extra power for, that's assuming they do no power optimisation on an architectural level.

    They may not even have to increase the TDP at all but there is the room for it, reason why I say this is I don't believe for a second that the 12 core will be cheap the lowest end 12 core SKU is likely to come in at $400+ and there highest end SKU to come in at $500. There real competition for the Icelake "9700k" is likely to be the 10 core which the highest end SKU is likely to come in at $350~ with the lower end SKU at $300~ to compete with the locked i7.

    The 8 core will compete with the i5, and I would assume it will come with SMT enabled so 8 cores 16 threads, and the 6 core 12 thread will compete with the locked i5 and a 6 core 6 thread will compete against what I would assume would be Intels 4 core 4 thread pricing is up in the air below the locked i5 because it depends on Intel's and AMD's yeilds and what the other company is charging.

    This means that AMD can somewhat maintain there Core / thread advantage while also closing the gap significantly in clocks and dropping the IPC gap to 2 – 4% so they wont need to hold a double core / thread advantage to be competitive and can settle for a 25% to 50% core advantage because the per core performance will be close enough that they wont need much of a core advantage to remain competitive.

    Also the small difference between the higher end 10 core and the 12 core will get some people to go ahead and take the plunge especially those who already own a Ryzen CPU who can justify the cost to them self's as they are not having to buy a new Motherboard and RAM aswell, and they got a fair chunk of there money back by selling there old Ryzen CPU, it is just generally a good plan in all area's.

    AND WRONG AGAIN! They said they would use the same chipset / socket until 2020 – 2021… GOD your terrible, also didn't believe the leaks that there would be a 8 core AMD CPU for $300 R7 1700 anybody? And this isn't even a leak these are thing AMD have said them self's.

    It is all about the new chipmachines being produced by ASML in the Netherlands. There is a new machine based on new ways of making extreme ultraviolet light. So yes there is going to be a very large improvement in chips during the next years.
