At Computex 2019 in Taipei, AMD CEO Lisa Su gave a keynote presentation announcing the first "7nm" Navi GPU and Ryzen 3000-series CPUs. All of the products will support PCI Express 4.0.
Contrary to recent reports, AMD says that the Navi microarchitecture is not based on Graphics Core Next (GCN), but rather a new "RDNA" macroarchitecture ('R' for Radeon), although the extent of the difference is not clear. There is also no conflict with Nvidia's naming scheme; the 5000-series naming is a reference to the company's 50th anniversary.
AMD claims that Navi GPUs will have 25% better performance/clock and 50% better performance/Watt vs. Vega GPUs. AMD Radeon RX 5700 is the first "7nm" Navi GPU to be announced. It was compared with Nvidia's GeForce RTX 2070, with the RX 5700 outperforming the RTX 2070 by 10% in the AMD-favorable game Strange Brigade. Pricing and other launch details will be revealed on June 10.
AMD also announced the first five Ryzen 3000-series CPUs, all of which will be released on July 7:
The Ryzen 9 3900X is the only CPU in the list using two core chiplets, each with 6 of 8 cores enabled. AMD has held back on releasing a 16-core monster for now. AMD compared the Ryzen 9 3900X to the $1,189 Intel Core i9-9920X, the Ryzen 7 3800X to the $499 Intel Core i9-9900K, and the Ryzen 7 3700X to the Intel Core i7-9700K, with the AMD chips outperforming the Intel chips in certain single and multi-threaded benchmarks (wait for the reviews before drawing any definitive conclusions). All five of the processors will come with a bundled cooler, as seen in this list.
Not to be outdone, Intel has announced the Intel Core i9-9900KS, a selectively binned 8-core processor that can boost to 5.0 GHz on all cores. The catch? TDP and pricing are currently unknown (i9-9900K launched at $488, 95W TDP), and Tom's Hardware reports that the higher clock speed does not apply to AVX workloads (although they will get a boost). The CPU does not come with a bundled cooler.
Intel also teased Gen11 integrated graphics performance, which will be included with "10nm" Ice Lake-U APUs. Their comparison shows a significant improvement over Gen9 graphics (there is no "Gen10") and a slight edge over AMD's top mobile processor, the Ryzen 7 3700U.

I'd really dig one but you can't disable the hardware rootkit like we're at least pretty sure you can with Intel chips . And I won't buy one even for an air gapped box if I can't at least be pretty sure I'm in charge of everything it does.
Arduino, others might but you will never need more
You can't disable the rootkit on Intel either. Only delete parts of the Intel Management Engine. The CPU itself is a microcoded black box with SMM as well. You don't control anything it does. The last CPU that fits your requirement is a 386 (before SL) on a motherboard without a proprietary BIOS. I don't think such a thing even exists.
Supposedly Purism can disable the Intel Management Engine, see https://puri.sm/posts/deep-dive-into-intel-me-disablement/ [puri.sm]
Some of the free-as-in-freedom software oriented shops made a business out of selling the last generation of AMD Opteron processors that had no such remote management system. Or at least, AMD hadn't announced their existence in those models or earlier.
But you do sacrifice a lot of performance. I wish every website was like sourcehut.org - simple HTML, no bullshit. Then a freakin' 2006-era PC would be great. But unless I want to give up 60% of my speed in the modern internet and also live with painfully slow application opening and compile times, I'm stuck.
Actually, the Phenom II x6 is still a perfectly acceptable processor today. I mean I'd greatly enjoy being able to `make -j32` and have one thread per core but it's not essential to my normal usage, even on Gentoo.
Heh, one of my two desktops has that model.

Feel free to write your own CPU and implement it on an FPGA, then only run code that you compiled after checking every line of the source.
The rest of us just minimize our exposure, having gotten to terms with the simple fact that you can't run anything less than a decade old without begrudgingly having to trust that the millions of lines of code and the billions of transistors are mostly working for you.
I've got a full tank of gas. Mow your lawn or burn it down ?
I ain't asking for absolute certainty. Just not having a chip that's actual purpose is to be a rootkit would be enough. Being fairly confident I can disable the worst of its functionality might even be acceptable.
