  STH: Tyan Transport HX TS75-B8252 Review Dual AMD EPYC PCIe Gen4

  "
  With dual AMD EPYC 7002 “Rome” series CPUs, we get PCIe Gen4 in a system that has been deployed many quarters before Intel delivers Ice Lake Xeons with PCIe Gen4 support. For those that need the bandwidth for accelerators or simply just InfiniBand or Ethernet networking, the PCIe Gen4 support is very important. Many early EPYC systems were still Gen3 so this is actually a differentiator. Being able to configure the up to 64-core parts with cTDP of 240W allows a few percent better performance as we showed in our testing by simply setting the configuration in firmware. These days, AMD EPYC has more cores and up to 8TB of DRAM support in a dual-socket 2U server which is why AMD servers are becoming more popular.

  The Tyan Transport HX TS75-B8252 exposes a delicate balance between providing high performance but also cost optimization. Even with those cost optimizations, the system has a surprising number of usability innovations that often do not add a lot of costs, but make working on the servers much easier. Overall the Tyan Transport HX TS75-B8252 is a solid 2U AMD EPYC platform that supports PCIe Gen4."
  
  
  
  nem sok dolog, van, amivel tuningolni lehet az EPYC-et,
  kivéve ez a cTDP ...
  
  "For those wondering, some AMD EPYC CPUs feature configurable TDPs or “cTDP” which allow chips to run at a higher TDP than their base rating. For example, the 64-core EPYC 7742 has a base TDP of 225W but it can run at 240W if the system allows for this configuration to be set. In the Tyan Transport HX TS75-B8252 we can utilize the extra 15W of TDP headroom which gives us a small but meaningful performance uplift. "
