Introduction, Specifications, and Pricing

While we have looked at other Z390 motherboards from GIGABYTE, today we take a look at our first one designed for content creators; the Z390 Designare. The Designare line targets content creators and modders, and for the most part has a white and black color theme as well as features for content creators, such as Thunderbolt 3.

In this case, GIGABYTE actually thought ahead and designed what we assume is the first Z-series motherboards to actually allow external input DisplayPort for Thunderbolt 3, specifically for the upcoming Intel consumer SKUs without integrated graphics. Let's see what this motherboard has in store for us.

Specifications

GIGABYTE has five fan headers on this motherboard, they are all hybrid DC/PWM mode headers so they can control both 3-pin and 4-pin fans. The one header circled in blue is also a water pump header, so we assume it runs at full speed at default or provides more current, but none of that is confirmed by GIGABYTE's marketing materials or manual.

The motherboard has a silver and black color theme to it, which is more professional than some of the other themes we have witnessed. The rear of the PCB is bare of major chips.

GIGABYTE Z390 Designare (Intel Z390) Motherboard Preview 08 | TweakTown.com

The rear IO panel features two USB 2.0 ports, PS/2 keyboard/mouse, DisplayPort in (for TB3), HDMI out, two USB 3.1 type-A ports, two ThunderBolt 3 (also double as USB 3.1 type-C), two USB 3.0 DAC UP ports, two USB 3.0 ports, dual Gbit LAN, and 7.1 audio with S/PDIF out.

The PCI-E layout is as follows, x16/x0/x0, x8/x8/x0, or x8/x4/x4. However, the last x4 slot has the ability to connect to the PCH or CPU for its bandwidth, a unique feature that allows for users to pick their best configuration. The x1 slots don't share bandwidth. There are two M.2 slots that operate in either x4 PCI-E 3.0 or SATA mode, and they share some lanes with some of the SATA ports. Both M.2 slots have heat sinks on them.

The VRM is a large 12+1 phase VRM consisting of 50A Vishay SiC634 DrMOS for the CPU phases and a single SiC620 60A DrMOS for the iGPU. It is controlled by an Intersil ISL69138 digital PWM controller in 6+1 phase mode, and six ISL6617 doublers are used to balance phase currents between each set of doubled phases.

The doublers are in synchronous mode, so a PWM readout would look like a large 6-phase VRM instead of a 12-phase one, so the doublers are used exclusively to balance the current between pairs of phases. The design compromise was made on these boards to improve transient response. On GIGABYTE's IR-based Z390 VRMs, the PWM readout would look like a 12-phase VRM because of IR's transient algorithms, so asynchronous mode is engaged on this board. Either way, the VRMs are very nice.

The VCCSA and VCCIO are controlled by Richtek RT8120 single phase PWMs with integrated drivers, and they control some miniature On Semiconductor PowerPAKs labeled "4C06". The memory VRM uses the same Richtek PWMs, but with larger On Semiconductor "4C06N" N-channel PowerPAKs in a two low single high configuration.

GIGABYTE is using the JHL7640 newer generation Thunderbolt 3 controller, which uses two PCI-E 3.0 lanes and offers two type-C ThunderBolt 3 ports, and features DP 1.4 output. The control these type-C ports and provide proper power delivery negotiation, two Texas Instruments TPS65983 type-C controllers are used, these are part of Intel's reference design.

So typically on Z-series motherboards with Thunderbolt we don't need an external video input since all the CPUs for the platform have an integrated graphics controller with DisplayPort (which is required for Thunderbolt).

However, the integrated graphics only offers DP 1.2, and there are newer KF and K SKUs coming out without integrated graphics. So GIGABYTE has added a Texas Instruments HD3SS215 DP differential switch, so users can use Thunderbolt 3 even without an iGPU and get a DP 1.4 input from an external GPU. The front panel type-C internal header uses a Pericom PI3EQX re-driver for native USB 3.1 and a Texas Instruments HD3220 type-C switch.

An NXP level shifter is used to provide an HDMI output on the rear IO panel. The motherboard Has six PCI-E quick switches to move PCI-E bandwidth between the three PCI-E x16 slots, you will notice two of these quick switches are made by Pericom instead of ASMedia, and that's because Pericom's product is a 3:1 mux/demux, so it can offer different sources for the bandwidth.

Thermal Imaging and Power Consumption

System power is measured at the wall with an AC power meter.

GIGABYTE Z390 Designare (Intel Z390) Motherboard Preview 76 | TweakTown.com

Note on Thermal Images: In the temperature section, we use our Seek thermal imaging camera to capture the surface temperatures of major components on the board. I look at the VRM and then all other things that light up the screen. If there is something to worry about, then I will state it. Otherwise, I will just show the hotter running parts of the board for fun. Unless some component is over 80-90C, then there isn't anything to worry about.

All systems will act differently, so I will look for commonalities, such as how far from the VRM the heat spreads through the PCB and the difference in temperature between the front side and back side of the PCB. Keep in mind, the majority of the heat from the VRM goes into the PCB as it is a giant soldered on copper heat sink. A larger difference in temperature between the back and front of the PCB points towards a more effective heat sink.

Thermal Testing at Stock Speeds:

The image on the left is always at idle, and the image on the right is at load. During ALL TESTS, fans to the right of the motherboard from the (Corsair H110i) radiator are left on automatic mode (ramps with internal block temperature). Additionally, a 120mm fan is situated right above the VRM, and it blows down at a medium rate (very quiet). Thermal Images are taken at loop 15 of Intel Burn Test

Up-close of the back of the VRM.

The Z390 Designare has an excellent VRM. Anything under 60C is great, 60-80C is acceptable, and anything above 80C is a bit worrisome (if at stock).

What's Hot, What's Not & Final Thoughts

What's Hot

Strong VRM: GIGABYTE did very well this round with VRMs, and in this case we have a full 12 phases of 50A DrMOS. The VRM is more than enough to overclock and unleash the full potential of the 9900K.

Thunderbolt 3: The Thunderbolt 3 controller here is based off Intel's Titan Ridge, and supports two Thunderbolt 3 type-C outputs with low power consumption. GIGABYTE also went a step ahead and added in the ability to use Thunderbolt 3 on the motherboard even if you are using one of Intel's unreleased CPUs without iGPUs. The ability to do that also allow you to plug into a GPU that supports DP 1.4, as the iGPU only supports 1.2, so you can take advantage of the 8K support from the new generation controller.

Flexibility of x4 Slot: GIGABYTE added in a unique feature ability, where you can choose where the bandwidth for the bottom x16 (x4 electrical) slot can come from (between CPU and PCH). We saw two types of quick switches used for the bandwidth of the slot. So why would GIGABYTE do this? Simple, if you want to run three GPUs, it's best to do it with CPU connected lanes, but if you want to run a x4 capture card instead, then it's best to be attached to the PCH so GPU bandwidth isn't reduced to x8 on the first slot. The ability also allows CPU attached dual NVMe PCI-E AIC RAID.

What's Not

No POST: On any non-mini-ITX motherboard I like to see a POST code display, but this motherboard doesn't have one.

Final Thoughts

The Z390 Designare has many secrets hidden under the hood. It has a 3:1 MUX feeding two quick switches providing the ability to choose where the bottom x4 comes from. That allows for easier configurations, and it seems also helps with AIC CPU RAID. On top of that, to take full advantage of the Titan Ridge Thunderbolt 3 controller, GIGABYTE adds in an external DP input, so you aren't limited to version 1.2 the iGPU supports and instead can take advantage of DP 1.4.

GIGABYTE Z390 Designare (Intel Z390) Motherboard Preview 83 | TweakTown.com

The motherboard is designed for content creators, and has a healthy serving of USB 3.0 and USB 3.1. GIGABYTE went above and beyond on the VRM, especially compared to competitor overclocking motherboards, and we didn't have issues clocking the CPU. Although the lack of a POST code bothered us, we would still highly recommend this motherboard to content creators.
