One of the questions that was left over from AMD’s Computex reveal of the new Ryzen 3000 family was why a 16-core version of the dual-chiplet Matisse design was not announced. Today, AMD is announcing its first 16 core CPU into the Ryzen 9 family. AMD stated that they’re not interested in the back and forth with its competition about slowly moving the leading edge in consumer computing – they want to launch the best they have to offer as soon as possible, and the 16-core is part of that strategy.
The new Ryzen 9 3950X will top the stack of new Zen 2 based AMD consumer processors, and is built for the AM4 socket along with the range of X570 motherboards. It will have 16 cores with simultaneous multi-threading, enabling 32 threads, with a base frequency of 3.5 GHz and a turbo frequency of 4.7 GHz. All of this will be provided in a 105W TDP.

AMD has said that the processor will be coming in September 2019, about two months after the initial Ryzen 3rd Gen processors, due to extra validation requirements. The chip uses two of the Zen 2 eight-core chiplets, paired with an IO die that provides 24 total PCIe 4.0 lanes. By using the AM4 socket, AMD recommends pairing the Ryzen 9 3950X with one of the new X570 motherboards launched at Computex.
With regards to performance, AMD is promoting it as a clear single-thread and multi-thread improvement over other 16-core products in the market, particularly those from Intel (namely the 7960X).
There are several questions surrounding this new product, such as reasons for the delay between the initial Ryzen 3000 launch to the 3950X launch, the power distribution of the chiplets based on the frequency and how the clocks will respond to the 105W TDP, how the core-to-core communications will work going across chiplets, and how gaming performance might be affected by the latency differences going to the IO die and then moving off to main memory. All these questions are expected to be answered in due course.
Pricing is set to be announced by AMD at its event at E3 today. We’ll be updating this news post when we know the intended pricing.
Update: $749

This move will kill their HEDT line.The real question is what will be AMD revenue advantage of this cheap silicon saga.
ps. why not 4.7Ghz turbo on 8 cores dies??? 16 cores are useless in games.
Bad move from AMD Reply

Kill? No. HEDT is more than just core count. remember Zen2 goes up to 64 cores. They still have 24 and 32 cores to go into. And even if they release a 16 core Threadripper 3, I bet it will sell very well because of quad channel memory, and way more PCIe lanes to work with.This is just giving us a new high core count chip on "mainstream" Reply

They absolutely SHOULD release a 2-chiplet 16-core Threadripper if they are still going to limit this platform to 4 channels (while the socket supports 8). Replyhaukionkannel - Thursday, June 13, 2019 - link
They save best chiplets for Rome and 3950! The 6 and 8 core cpus gets the worst cpus They can find, because it does not matter if They eat more energy. The 16 core has ro have reasonable good cpu chiplet or it would run out of energy too early... ReplyChubChub - Friday, June 14, 2019 - link
The way AMD boosts clocks is largely based on TDP/motherboard limitations; it's a very clever system that rewards superior cooling solutions. TDP can be adjusted, meaning your available boost clocks will adjust accordingly (assuming you have the proper cooling). The benefit of this system will be clear once the new AMD chips are compared against their Intel counterparts; Intel's heavy reliance on going way out of spec. will become (more) obvious.So, the 4.7GHz of the 16C chip is able to be advertised mostly because the base clocks are low, leaving a lot more headroom to boost specific cores to guaranteed 4.7GHz (most chips will likely boost above this, bone stock). If you take a 12C (8C) chip and mess with the chip's limitations, you'll see similar boost clocks.
TL;DR: Worry not, the 8C chips will be boosting in the same range as the 16C ones are, much like what is happening with the Zen+ parts. Reply

AMD is probably binning their best dies for the 16-core part.I hope they eventually release an 8-core that turbos to 4.7 GHz. Reply

Wow you have to go down from a Ryzen 9 3950X to a Ryzen 7 3700X to go down in TDP from 105W to 65W, in Mini ITX builds where higher watts = more heat it can be pretty crucial. Im surprised that they dont decrease the wattage for all those disabled cores when you go down in cpu level. One other thing is that all the new X570 boards are HUGE! either Full ATX or E-ATX but I havent seen any Mini-ITX or Micro-ATX motherboards with X570 yet from any manufacturer.

The 3800x was marked as 95W this show, but 105W at computer, but I believe 95 might be right Replyschujj07 - Tuesday, June 11, 2019 - link
Gigabyte has a mini-ITX.https://www.anandtech.com/show/14460/gigabyte-unve...
The 3950X will create less heat in an ITX space than either the 9700K or 9900K and people put those into ITX cases all the time. Reply

Thanks for that link, on a side note DAT BACKPLATE! is huge lol Reply
