GIGABYTE Z390 Gaming SLI

Not all of GIGABYTE's gaming range is underneath the Aorus banner and the primary example on the Z390 chipset is the Z390 Gaming SLI. In regards to the design, the board has a black color scheme throughout with slim red accents on both the power delivery and chipset heatsinks. The board makes use of three full-length PCIe 3.0 slots with the top slot operating at x16, the middle slot at x8 and the bottom at x4. The top and middle slot have a coating of metallic slot protection and due to the middle slot operating at x8 and as the name suggests, this model does support two-way SLI graphics configurations. The onboard Realtek ALC1220-VB codec has EMI shielding and the power delivery looks to be running in an 8+4 or 10+2 configuration; this is supplemented by a pair of 12 V ATX CPU power inputs which consists of an 8-pin and a 4-pin.

Memory support on the Z390 Gaming SLI consists of four RAM slots with a maximum capacity of up to 64 GB; the maximum rated XMP profile is currently unknown as of yet. The onboard audio is provided by a Realtek ALC1220-VB audio codec which offers six 3.5 mm audio jacks on the rear panel; the single LAN port is controlled by an Intel I219V Gigabit networking chip. A total of eight USB Type-A ports are present which are split into two USB 3.1 Gen2 and six USB 3.0, with a combo PS/2 port and a single HDMI video output also present.

While this board is similar in spec to the Z390 Aorus Elite, it currently costs just $160 and represents one of GIGABYTEs cheapest Z390 models at launch. Based on this the targetted segment is likely to be budget gaming with certain cost-cutting measures in place such as rear panel connections, but without sacrificing on support and componentry such as power delivery needed to run Intel's top 9th generation processor the Core i9-9900K.

    Thank you Hickory, will update now; this information wasn't available to us at the time

    All this boards, but only 1 with Thunderbolt 3. Looks like Thunderbolt 3 is dead (free or not).
    Type C ports and HDMI 2.0 is in short supply too.

    Hopefully next year, we can have two or more USB C (maybe even 3.2), HDMI 2.1, PCIe 4/5 and Thunderbolt 3/4 (Titan Ridge?). Or maybe not, just the same old things hoping for 2020/21.

    There's no licensing fee for TB, the controller chip itself still costs money (IIRC $20 or $30) and still eats 4 PCIe lanes. Worse, IIRC to make the video out feature work they need to be CPU lanes; meaning that adding it means your main GPU slot is an x8, and the secondary one only x4.

    Yeah it's a case of certain vendors opting to dismiss including TB3 ports, which only seems sensible on mini-ITX boards where PCIe lanes aren't too much of an issue. Consumer choice is important though and I'm still glad ASRock has included it; it could be a key buying decision for some!

    Just too bad it is only wired as a x2.. And it is wired into the chipset as far as I am aware, so you are gonna max out your I/Os pretty fast.
  • bill44 - Wednesday, October 10, 2018 - link

    Sure, anything you add will cost something. The are plenty of non-gamers who prefer TB3 vs x16.
    This also highlights how old current PC architecture is. Either we need more PCIe lanes, or faster lanes. Otherwise, all advances will be hindered.

    Up to 6 USB 3.1 Gen 2 ports? You’ be lucky to get 4. Why can’t we have 6 Gen2 ports and the rest Gen1 an no antiquated USB 2.0? PCIe resources.
    All new peripherals use Type C, but this boards generally give you only 1 (saving money on redrivers). USB 3.2 (20 Gbps)? When it comes around, ithis too will need more PCIe lanes. M.2. PCIe 3.0 x4? All lanes are maxed out; the only way forward is faster lanes.

    In the past, Gigabyte was a TB3 champion including the functionality on many of their boards. Now, not a single one.

    Cost saving by motherboard makers? Prioritising gamers? Or simply no demand for TB3.
    The outcome is the same.

    Intel merely said that they planned "to make the Thunderbolt protocol specification available to the industry under a nonexclusive, royalty-free license" sometime this year. This hasn't happened yet, and is referring to the protocol spec, not the silicon that Intel produces. If and when they decide to do this, ASMedia or whoever could then begin development of their own Thunderbolt controllers. This means that third-party controllers probably won't appear in shipping products until sometime in 2023.

    As for the currently available Thunderbolt 3 controllers, tray prices range from $6.45 to $9.10. But you also need a USB Type-C and PD controller, power switch, and high-speed mux which runs around $4.59, plus the connector and a few other bits. I don't believe Intel charges a royalty on finished Thunderbolt products, but they do require licensing and certification which are paid for by the OEM and may add significant cost to relatively low-volume products.

    AFAIK, Windows PCs are still required to connect Thunderbolt controllers via the PCH. Apple is the only one using PEG lanes for Thunderbolt, and they don't do that on the 27-inch iMacs where it might adversely impact the GPU.

    I hope it's not dead. Far more useful than USB C. I would be fine with USB C except there doesn't seem to be a good USB C to USB C hub, which really restricts how many devices you can use. I'm really glad to see it on ASRock itx board so I can attach a portable SSD array.

    Tons of monitors of USB-C, anker sells USB-C hubs, I don't think i've seen thunderbolt in a desktop PC to date though. That best part of USB-C is being able to just plug phone into it and copy paste to desktop files (no Microsoft didn't invent that, it was always that way by default in windows)

    TB3 is far from dead, it just has little use in desktop PCs. Have you looked at laptop lineups recently? TB3 is _everywhere_. My workplace (a major university here in Norway) has moved entirely to TB3 docking solutions as they're the only full-featured and universal(-ish) solution.

    eGPUs are useless on desktops. Desktops don't need docks. USB 3.1 is plenty fast for external storage, and if you need faster storage, desktops can fit that internally. The only real use cases for TB3 on a desktop are TB3 networking (for fast direct transfers between PCs) and adding things like extra NVMe or >GbE networking on ITX boards that don't have room for that and a GPU.
