Not the OP, but I was looking to buy a couple of these for my team for database code optimization work. I have an older TR build with 128 GB or RAM, 3x nVME, 2xSSD and 3xHDD (3 tiers of storage performance) built for about $3000, so we can run almost any database from production on it and tune the code and indexes. With 8 memory channels we can go to 256GB of cheap UDIMM (32GB each) instead of using expensive high density RDIMM or LRDIMM. Also the number of PCIe connections allow for enough nVME drives, something a desktop CPU - AMD or Intel - cannot do.
From my limited perspective, the 2 benefits of TR over Ryzen at low CPU count are the PCIe lanes and memory channels and slots. If you need a high CPU count then there is no other choice but TR.
- CobaltFire 6y agoPlease note these are restricted to RDIMMs. They are essentially rebranded EPYCs. I chose this system for exactly the reasons you listed at "low" (is 12 low now?) core counts: PCIe lanes and memory bandwidth. Also, it's just awesome.
- AdrianB1 6y agoIs it limited? The CPU supports UDIMM and LRDIMM in addition to RDIMM, so if there is any restriction then it is coming from Lenovo, not from AMD.
- CobaltFire 6y agoYou have a point; RDIMMs were cost effective enough for me that I didn’t think to investigate further. I can see if I can scare up some UDIMMs and test, but I don’t think I have any DDR4 around.
