Bit of a wet fart though, even Charlie D thinks it's too little too late. OEM-only (and only on WRX80 socket), no V-cache, worse product support. https://semiaccurate.com/2022/03/08/amd-finally-launches-threadripper-pro-5000/ https://semiaccurate.com/2022/03/08/amd-finally-launches-thr... The niche for high clocks was arguable with the 2nd-gen products but now you are foregoing v-cache which also improves per-thread performance, so Epyc is relatively speaking even more attractive. And if you take Threadripper you have artificial memory limits, half the memory channels, half the PCIe lanes, etc, plus in some cases it's more expensive than the Epyc chips. It is a lot to pay (not just in cash) just for higher clocks that your 64C workloads probably don't even care about. AMD moved into rent-seeking mode even before Zen3 came out. Zen2 threadripper clearly beats anything Intel can muster in the segment (unless they wanted to do W-3175X seriously and not as a limited-release thing with $2000 motherboards) and thus AMD had no reason to actually update this segment when they could just coast. Even with this release, they are not refreshing the "mainstream" TRX40 platform but only a limited release for the OEM-only WRX80 platform. It was obvious when they forced a socket change, and then cranked all the Threadripper 3000 prices (some even to higher-levels than single-socket Epyc "P" skus) what direction things were headed. They have to stay competitive in server, so those prices are aggressive, but Intel doesn't have anything to compete with Threadripper so AMD will coast and raise prices. And while Milan-X isn't cheap - I doubt these WRX80 chips are going to be cheap either, it would be unsurprising if they're back in the position of Threadripper being more expensive for a chip that's locked-down and cut-down. And being OEM-only you can't shop around or build it yourself, it's take it or leave it.

  The PRO Threadrippers are not cut down, they have 8 memory channels and 128 PCIE 4.0 lanes. I think the only limitation compared to Epyc is that you can have 1 socket only.

    And WRX80 has dedicated chipset lanes (https://www.amd.com/en/chipsets/wrx80 https://www.amd.com/en/chipsets/wrx80), so effectively more PCI-e than EPYC, and bootable NVME RAID support on top.
