Third-generation AMD 7nm ThreadRipper processors make use of the 14nm TRX40 platform. It is not backwards-compatible with first- or second-generation ThreadRippers, though the primary difference is in pin layout (the number of pins has not changed). It utilizes LGA (Land Grid Array—FCLGA-4094 to be precise) and is speced at 15W. AMD recommends liquid cooling for the 32-core 3970x and 64-core 3990x.

I'm likely going with a Gigabyte Aorus Master plus a 3970x.

CPUs

Model MSRP Cores Clocks
3990X $3990 64 2.9/4.3
3970X $1949 32 3.7/4.5
3960X $1399 24 3.8/4.5

TRX40

The TRX40 chipset is built around the sTRX4 socket, and supports:

  • Quad-channel DDR4 w/ optional ECC
  • Up to 72 PCIe 4.0 lanes
    • The CPU provides 56 lanes, and the TRX40 chipset another 16.
    • AMD literature quotes "88 lanes". The 16-lane difference refers to internal uplink lanes. Kinda lame to quote them, IMHO.
  • Up to 12 USB3.2
  • Up to 4 USB2.0
  • Up to 20 SATA III
  • Up to 2 4x NVMe

Motherboards

I'm kinda bummed by at least the initial set of TRX40 motherboards. They all tout high-end audio implementations—largely because the chipset doesn't offer HD Audio capability(!)—but anyone who cares about their audio switched to an external DAC years ago IMHO. I'd like to see a few more x1 and x4 slots on these boards; no one has more than a 4x16+1x1 physical configuration. The introduction of 10GigE is nice to see, but I've already got cards for that (I must admit that this reclaims a slot). Almost all the onboard NICs are Intel or Aquantia, both manufacturers with much better Linux support than Realtek or, Allah forbid, Broadcom. In particular, everyone's offering Intel wireless (since the AX200 is the only mainstream IEEE 802.11ax aka WiFi6 chipset), which is lovely.

At these price points, there's absolutely no excuse for an unattached I/O shield. Firm that shit up.

The Gigabyte Aorus XTREME, ridiculous name aside, is an absolutely beautiful board.

Cooling

Third-generation Threadrippers are rated at 280TDP at a large 58.5mm×75.4mm geometry. As of February 2020, very few AIO coolers cover the entire IHS (integrated heat spreader).

Waterblocks

Remember, any waterblock designed for TR4 will work fine with sTRX4. Only the pin configuration changed.
