Yes, but only a limited UDIMM variant which makes it much harder to source memory for. It's gotten a little easier over the last year, but these new Pro variants will have support for RDIMM, LRDIMM, etc. DIMMs which will make it much easier to find memory at a reasonable price.
- PragmaticPulp 6y ago16GB and 32GB ECC UDIMMs are easy to find and reasonably priced: https://www.cdw.com/product/samsung-ddr4-32-gb-dimm-288-pin-unbuffered/5899887 https://www.cdw.com/product/samsung-ddr4-32-gb-dimm-288-pin-... The real advantage of the PRO processors is that they support 8-channel memory and have more PCIe lanes. The higher TDP spec might allow for higher all-core turbo, too.

Same TDP spec as the existing non-pro threadrippers - 280W. > The real advantage of the PRO processors is that they support 8-channel memory and have more PCIe lanes. Those are advantages yes but the other DIMM types means you can also actually exceed 256GB of RAM, which with 64-cores is definitely also a bottleneck on the existing Threadripper lineup
- PragmaticPulp 6y ago> Same TDP spec as the existing non-pro threadrippers - 280W. The current 280W TDP Threadrippers are 24, 32, or 64 core. These new Threadripper PRO parts have 280W TDP even down to 16 and 12 core parts.
- leoc 6y ago256 GiB is also supposedly a bit of a low ceiling for serious 4K video work, never mind 8K (please forgive the not-prestigious source): https://youtu.be/1LaKH5etJoE?t=926 https://youtu.be/1LaKH5etJoE?t=926 I wouldn’t be astonished (not an expert) if unhappiness from video professionals was an important reason behind the release of the Pro.
- binarycrusader 6y agoYes, some DIMM configurations are easier to find now, but when Threadripper was first released they were all but impossible to source. However, even if 16GB and 32GB are easy to find, that won't let you get anywhere near the 1TB limit of the first systems to ship or the technical limit of 2TB as other posters pointed out. It's just not realistic to equate the two as equal -- these new systems are definitely going to unlock use cases that aren't possible with the regular Threadripper.
- amarshall 6y ago> that won't let you get anywhere near the 1TB limit of the first systems to ship or the technical limit of 2TB as other posters pointed out. The limit of TRX40 is 256 GB max, 32 GB individual, and WRX80 supports RDIMMs, so finding larger UDIMMs is pointless, anyway.
- binarycrusader 6y agoEarly on there were claims from some that 64GB UDIMMs would work when they existed or would be supported when they did. But yes, I agree otherwise. I seem to recall spotting some special order 64GB UDIMMs recently (for sampling only at OEM level).
- gruez 6y ago>The higher TDP spec might allow for higher all-core turbo, too. Is there a difference in silicon quality, or is it essentially PBO[1] being preapplied? In other words, can you get the same effect by getting the non-pro part and going into your mobo setting and setting the power limit higher yourself?
