AMD Announces 3rd-Generation Threadripper CPUs, Ryzen 9 3950X available on November 25th, and More

Accepted submission by takyon at 2019-11-07 18:12:03

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 will publish a list of recommended coolers instead. [add link here when available]


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.
