ASRock Z390 Phantom Gaming 9 Review: The 2.5GbE Value Play

How We Test

We're comparing the Z390 Phantom Gaming 9 to its most direct-priced competitor, Gigabyte's Z390 Designare, along with the 10GbE-equipped Z390 Taichi Ultimate and two other boards from Gigabyte and MSI.

The same platform that cooled the 10 cores of our Core i9-7900X worked equally well with the eight cores of the Core i9-9900K, as we’ll show in the overclocking evaluation on the next page.

    Excellent thanks for the review!

    Do you need to buy a special 2.5 gigabit router/switch for this to work?

    Even something as crazy looking as the ROG Rapture GT-AC5300 makes no mention of it supporting 2.5 gigabit wired.

    5GbE switches should all be wired for it, but I don't know which 10GbE switches will support it.

    You need a switch that supports it yes, 2.5G and 5G are part of the N-Base-T standard. Some 10G switches will also support these speeds, now or in the near future.

    Was there a section on the performance of the 2.5GbE that I missed? Or is the network speed not tested in this article?
  • hassanergene
    I did not see benchmarks on ethernet either; however, by the nature of how copper ethernet works a PHY is a PHY, it will always transmit at line rate (e.g. 2.5Gbps always). The only way to tune it is to change packet size, e.g. enable jumbo frames you will get more data through since there is less preamble/packet info transmitted, more raw data. These PHY's need to interoperate so they follow a strict standard and data rate with one acting as a master and the other as a slave to stay in sync. So there isn't too much point in benchmarking network cards. The thing about these cards though is since their data rates are higher there is less latency on the MAC layer since they have to operate faster in order to support the faster line rates. In a way it is overclocking the PHY to MAC layer with faster ethernet standards.
