AMD has announced its latest Threadripper high end desktop CPUs, along with a launch date for the Ryzen 9 3950X:

AMD is set to close out the year on a high note. As promised, the company will be delivering its latest 16-core Ryzen 9 3950X processor, built with two 7nm TSMC chiplets, to the consumer platform for $749. Not only this, but AMD today has lifted the covers on its next generation Threadripper platform, which includes Zen 2-based chiplets, a new socket, and an astounding 4x increase in CPU-to-chipset bandwidth.

Reviews of the 16-core 3950X will appear on November 14, with retail availability on November 25. The "mainstream" CPU has a 3.5 GHz base clock, 4.7 GHz single-core boost clock, and 24 PCIe 4.0 lanes. Unlike most Ryzen CPUs, the 3950X will not come with a bundled cooler, and AMD has published a list of recommended coolers instead.

All Ryzen 3000-series CPUs can now be configured to use a lower TDP using AMD's software:

One side announcement from AMD, regarding all of the Ryzen 3000 hardware, is that every CPU now supports a cTDP down mode through the Ryzen Master software. With the tool, users can select the next power range down from the TDP of the processor. This means that 95W/105W CPUs can be set to run at 65W, then the 65W CPUs can be set to run at 45W, and the 45W CPUs can run at 35W.

AMD is doing this because they have seen a number of customers request high-core count processors at lower TDP values. Rather than releasing a wide array of X and non-X parts to satisfy all different areas of the market, AMD is offering this 'cTDP down-like' option for system builders that do want to focus on something like a 65W 16-core processor for their system. This isn't to say that AMD will not release non-X CPUs in the future (they're typically cheaper than the X CPUs), but rather than have customers wait for those parts to enter the market, AMD is giving this option to speed up adoption.

The initial Threadripper 3 CPUs are the 24-core 3960X ($1400) and 32-core 3970X ($2000), also launching on November 25. These chips require a new sTRX4 socket and TRX40 motherboards. The new chipset will allow motherboard manufacturers to offer different combinations of PCIe 4.0 lanes, SATA ports, NVMe slots, etc. Threadripper 3 supports higher clocked and denser RAM than the previous Threadripper CPUs:

Each CPU supports four channels of DDR4-3200. We confirmed that this included support for ECC UDIMMs on a board-by-board basis, but does not include RDIMM or LRDIMM support. AMD did state that these new CPUs are validated for the 32 GB DDR4 modules coming onto the market, which makes a realistic maximum DRAM support of 256GB (8 x 32GB).

A 48-core 3980X or 64-core 3990X is expected to be announced in January, but neither CPU has been confirmed by AMD yet.

At the very opposite end of the lineup, AMD has announced the Athlon 3000G, a 35W dual-core Zen+ ("12nm") APU with a bundled cooler for just $50. It comes with 3 Vega graphics compute units, compared to 8 for the $100 Ryzen 3 3200G or 11 for the $150 Ryzen 5 3400G.

    If so, are they going to open source the code?

    If you are worried about that shit go get a pc from before 2005 and run tails on it. For surfing porn, folding proteins, shitposting to sn, and simulating the universe there is no reason to care.

      2012ish for AMD CPUs if you use an older chipset, 2010 (Westmere) if your motherboard does't have the ICH10 (many had ICH9 instead, negating intel ME). Pre AM4 or LGA115x are mostly safe with methods to remove the firmware modules where they are not. Later processors include Process bootstrapping and signed memory initialization code in their SP/ME code modules.

      I think if anything the past decade has shown, it's that any potential backdoor will, sooner or later, be exploited. Building systems with potentially severe security vulnerabilities, let alone in the name of security, is just not a good idea.

      Although even before the exploits become mainstream and it's your banking and various account informations being hacked, I would not rest easy with all your information 'just' being in the hands of the various nations' government intelligence agencies. See things like 'LOVEINT [slate.com]' at the NSA. That spying on lovers and various other personal interests has its own name is kind of telling. The article mentions only a relatively small number of incidents have been discovered (about a dozen so far), but those are of course only the incidents that end up with the individual getting busted. Presumably NSA guys with top secret clearance are also the type that have a better than average idea of how to do things covertly.

      Regardless, the point is that government isn't some singular entity - it's just made up of a bunch of normal (or less than normal... ) people. And so you should feel as happy with the NSA having all of your personal information as you might any other stranger who now knows exactly who you are alongside whatever data has been compromised.
