The ThunderX SoCs

Below you can see all the building blocks that Cavium has used to build the ThunderX.

Depending on the target market, some of these building blocks are removed to reduce power consumption or to increase the clockspeed. The "Cloud Compute" version (ThunderX_CP) that we're reviewing today has only one accelerator (vSwitch offload) and 4 SATA ports (out of 16), and no Ethernet fabric.


But even the compute version can still offer an 8 integrated 10 Gbit Ethernet interfaces, which is something you simply don't see in the "affordable" server world. For comparison, the Xeon D has two 10 Gbit interfaces.

The storage version (_ST) of the same chip has more co-processors, more SATA ports (16) and an integrated Ethernet fabric. But the ThunderX_ST cuts back on the number of PCIe lanes and might not reach the same clockspeeds.


There is also a secure compute version with IP Sec/SSL accelerators (_SC) and network/telco version (_NT). In total there are 4 variants of the same SoC. But in this article, we focus on the version we were able to test: the CP or Cloud Compute.

    I could hardly disagree more about the remote management of SuperMicro vs. HP. Remote management of HP is *the horror*, I've never seen worse and I've seen a lot. It's clunky, it requires a license to be useful (others do to but SuperMicro does not have such nonsense), the BCM tends to crash a lot (which is very annoying for a remote management solution), boot is even slower than all other systems I know due to the way they integrate the BIOS and remote management on the system and it also uses Java unless you have Windows machines around to use the .NET version.

    For the remote management alone I would chose SuperMicro over most other vendors any day.

    I found the .Net client of HP much less sluggish, and I have seen no crashing at all. I guess there is no optimal remote management client, but I really like the "boot into firmware" option that Intel implemented.

    Not only that but Supermicro actually releases updates for their BCM's. I had the same shocked reaction to the HP claim. Started to wonder if I was the only one that thought supermicro was light years ahead in usability.

    I should note that Supermicro's awful Java tool works on Linux as well as windows. Though it refuses to run if your Java isn't the newest version available.

    All these articles and yet still no review for the GTX 1080, while other major sites have already posted their reviews of both 1070 & 1080. Guru3D already has 2 custom 1080 and a custom 1070 review up.

    It'll be done when it's done.

    Unacceptably late for something that should've been posted weeks ago.

    Will anyone read it though? Your ad impressions are going to suffer.
  • Ryan Smith - Thursday, June 16, 2016 - link

    Maybe. Maybe not. But it's my own fault regardless. All I can do is get it done as soon as I reasonably can, and hope it's something you guys find useful.

    Give it a freaking rest. No-one is impressed by your constant whining about this.
  • pencea - Thursday, June 16, 2016 - link

    Not looking to impress anyone. As a long time viewer of this site, I'm simply disappointed that a reputational site like this is constantly late for GPU reviews.
