    Curious what kind of MSRP we’ll see on the 3990. $4k?

    4k, seems to be what people expect. Only downside is you can "only" have one at a time, unless you get Epyc of course!

    Never fear, Zen3 will have even more cores ;)

    Maybe. I’m not expecting another big jump in core count until they transition to 5nm. AMD is doing great but the laws of physics do still apply to them.

    True, but more cores is one of the improvements that AMD's execs have been talking about, since the new lithography nodes aren't leading to significant clock speed boosts.

    From Techspot: "N7+ has identical yield rates to N7 and will steadily improve, while also offering a 20% increase to transistor density. There’s also a 10% performance uplift or 15% power efficiency increase."

    There is room for 2 more cores per die, who knows...

    TSMC 5nm on track for Q2 202 HVM will ramp faster than 7nm.

    AMD also has some of the most advanced multi-chip packaging in the business, so might be planning on adding more of those also...

    There is room for improvement on a given process node but you’re not going to get to 128 cores on 7nm. They’re already pushing the limits of realistic cooling capacity at 280w TDP. Personally I’d like to see they stay at 64 core another gen and use process improvements on higher clock speeds. If they reduce the IO node to 7nm also that will buy them some headroom.

    The clock speed increases that they're getting according to Mark Papermaster are pretty small, but the efficiency improvement is better, and the 7nm EUV process has better transistor density. With the improvements in cooling for laptops going on, I don't agree about the cooling limitation any more. On top of that, I'd expect part of the core count increase to come from additional chips in the chip carrier, rather than a large increase in cores per chiplet. And then of course accounting for comments from several AMD folks saying that AMD is going to continue to push core counts... :)

    We might not get all the way to 128 cores on the 7nm EUV process, but since the 5nm process isn't far behind and is in fact coming online more quickly than the 7nm process did, it probably won't be long.

    We got our hands on a pre-release PC here at RED and it can achieve real time 8K 24fps REDCODE RAW playback with only it's new CPU, with some headroom to spare. And with this week’s R3D CUDA SDK release, you can also utilize GPU acceleration and then use that CPU horsepower for transcoding, effects processing, etc.

    Can't wait to see this CPU hit the market.. I think you all will be very, very happy.

    GPU acceleration off, CPU decode Only:
    From a tease to the actual announcement in 2 weeks!
    What a fun way to start the year!!!
    Thanks Jarred! Here's to a happy and productive 2020!!!
