Tech News

  • Ian Cuttress talks to AMD CTO Mark Papermaster.  (AnandTech)

    Couple of points of interest:

    • Naples (Epyc 1) required four functional CPU dies to work.  Rome (Epyc 2) requires a functional I/O die, and any number of CPU dies from 1 to 8.

      If yields are good we're likely to see chiplet granularity in Rome's core count - and the same with Threadripper 3.  Threadripper 3 will be a beast; Intel will be dead in the single-socket workstation space.

    • Milan (Epyc 3) will have the same socket as Naples and Rome.  After that (Venice?  Genoa?  Florence?) we're looking towards DDR5 and PCIe 5.0 and "no comment" territory. 

    • Infinity Fabric on 7nm offers 100GB/s bandwidth, more than double the first generation.  This helps mitigate the smaller number of interconnects - Naples has 12 interconnects for 4 dies; Rome has 8 for 8 dies.

    • Chiplets mean you can mix and match - need an application-specific core?  FPGA?  GPU?  As long as it speaks Infinity Fabric and fits on the package, it can be done.

  • Another day, another side channel attack...  On Nvidia graphics cards?!  (Tom's Hardware)

    Ugh.

  • Epyc clouds get benchmarkeded.  (Phoronix)

    AWS vs. Packet vs. SkySilk (who?)

    STOP TRYING TO MAKE "retpoline" A WORD.  IT IS NOT A WORD.

    A SkySilk "small" node outperforms an EC2 m5a.large node.  That means less than it sounds like, though, because both are dual core 8GB nodes with similar pricing, and the naming conventions mean even less than they do at Starbucks.

  • Cloudflare's 1.1.1.1 app competes with 8.8.8.8 and 9.9.9.9.  (Bleeping Computer)

    First, this is good, because your ISP's DNS probably sucks.  Second, IP routing is fucking weird.

  • HTTP/2, based on Google's SPDY, is set to be replaced by HTTP/3, based on Google's QUIC.  (ZDNet)

    Not sure how I feel about that.  They're not even using TCP any more.  They've smushed HTTP itself, TLS, and a rewrite of TCP into a protocol that runs over UDP.

    It's dead easy to write an HTTP server if you can talk TCP, and everything can talk TCP.  This does not make things simpler.  Very much the opposite.

Other Linus buys weird CPUs on Taobao so you don't have to.

Apple pies are delicious. But never mind apple pies. What colour is a green orange?
