The latest flagship desktop processor from Intel, the Core i9-11900K, has been out for over a month, and we've been busy putting numerous Z590 motherboards on tests to see how some of the motherboard options stack up against each other. Up for analysis today is GIGABYTE's Z590 Aorus Master, which is one of its premium models and has plenty of high-quality features and controllers onboard. Based on the Aorus gaming series, the Z590 Aorus Master includes 10 gigabit Ethernet, Wi-Fi 6E, three M.2 slots, and large power delivery. From the specifications, it's a behemoth but with an attractive price tag when compared to the flagship Z590 offerings.

From our experience with previous generations of Intel's premium desktop chipsets, including Z490, Z390, Z370, etc., we've seen numerous trends of motherboard vendors stacking features onto its PCBs. Ultimately, the better the feature set, the more it costs, which is understandable, but Intel's Z590 offers some of Intel's biggest updates from a desktop-based chipset from them in years.

Aside from the PCIe 4.0 support that the 11th generation Rocket Lake processors bring to the table, the Intel Z590 chipset, when paired with Rocket Lake, effectively doubles the bandwidth between the CPU and chipset's DMI to x8, as well as native support for Wi-Fi 6E CNVi, which uses the latest 6 GHz Wi-Fi band for uninterrupted wireless access. Another addition native USB 3.2 Gen2x2  connectivity, which is fantastic for content creators and users with compatible devices. 

GIGABYTE Z590 Aorus Master Overview

As far as premium GIGABYTE Z590 models go, the Z590 Aorus Master sits just behind GIGABYTE's flagship water-cooled Z590 Aorus Xtreme WaterForce and air-cooled Z590 Aorus Xtreme models. Regarding usable and core features, the Z590 Aorus Master has pretty much what you would expect from a mid-premium model. What GIGABYTE does have is plenty to focus on, including a nice aesthetic, with a predominately black PCB, black heatsinks, and black and silver PCIe slot armor, as well as matching M.2 heatsinks.

Focusing on the features, there are three full-length PCIe slots, all with GIGABYTE's metal slot reinforcement, with the top two slots operating at PCIe 4.0 x16 and x8/x8, with the third electronically locked down to PCIe 3.0 x4 from the chipset. Regarding memory support, GIGABYTE has QVL'd memory up to DDR4-5400, which is impressive, and the four slots can accommodate up to 128 GB. GIGABYTE also includes three PCIe M.2 slots, with one operating at PCIe 4.0 x4 and the other two at PCIe 3.0 x4, with the Gen 3 pairing also with support SATA based SSDs. There are also six SATA ports for conventional storage devices and optical drives, with RAID 0, 1, 5, and 10 arrays supported across all six ports.

The networking is as good as it gets on a desktop motherboard with a 10 GbE controller and Intel's latest Wi-Fi 6E CNVi. The rear panel includes USB 3.2 G2x2 Type-C, with an internal USB 3.2 G2 Type-C front panel header located below the memory slots. GIGABYTE uses an amped-up onboard audio solution with a premium HD audio codec and DAC combination, with one Displayport 1.2 video output for users intending to leverage Intel's integrated graphics. 

Looking at the performance of the GIGABYTE Z590 Aorus Master, we saw very competitive performance when compared directly against other models. This includes fast POST times in our system testing and reasonable power consumption, and adequate performance in our DPC latency testing. In our gaming and compute-focused benchmarks, we again saw competitive performance against other Z590 models on test, and we saw no areas of concern or any anomalies.

The GIGABYTE Z590 Aorus Master undergoing VRM thermal testing

When we overclocked the GIGABYTE Z590 Aorus Master, we saw very tight VDroop control with the default load-line calibration settings on its large 18-phase CPU setup for the power delivery. We managed to get 5.2 GHz all-core on our Core i9-11900K, despite the large 413 W power draw from the wall with a maximum core temperature of 88 degrees Celsius. The performance went up incrementally in our POV-Ray benchmark, with some hit to performance at 5.2 GHz, which is likely related to the thermals or possibly built-in power limitations. We also tested the thermal capability of the power delivery, and although warmer than we expected, we did observe temperatures ranging from 71 to 78ºC with our K-Type thermocouples and the integrated temperature sensor on the board.


At present, the GIGABYTE Z590 Aorus Master is available for $410 at Amazon, which is a fair price considering the mixture of premium controllers and features. This is similar to the ASRock Z590 Taichi, which is available for $430 at Newegg and includes Thunderbolt 4, but take away the Thunderbolt 4, and the Master has the better overall specifications on paper, especially within its power delivery capabilities. Other boards to consider are the ASUS ROG Strix Z590-E Gaming WIFI ($380) and the MSI MEG Z590 Ace ($500), which both should be judged on their own merits. GIGABYTE looks to dominate the market below the flagship models. The Z590 Aorus Master looks to solidify its position as a leading model with 10 GbE, Wi-Fi 6E, and plenty of other high-quality features.

Read on for our extended analysis.

    'well just because they eliminated a warranty option may just mean no one was buying it'

    I'll buy that for a dollar.

    Overall, I am happy with this product. DDR-4400, overclocked 11900k at 5.1ghz all cores, gen4 NVMe SSD, 3080 running 16x gen4.

    However, there was an issue that x570 PCIE gen4 users encountered, that they seem to be correcting. If you had a gen4 NVMe + gen4 graphics card, every 300ms you would get a WHEA-LOGGER event and the computer would BSOD every 1-2 hours. After many responsive emails from their customer support, BIOS version f5d now allows a NVMe gen4 + graphics gen4 without crashing. There is still a WHEA-LOGGER message every 300ms which is noise, but that should be fixed with a future Intel Chipset update.

    You talking about AMD chipset issue, but this motherboard is based on Intel chipset. Completely another story.
  • JVC8bal - Friday, April 30, 2021 - link

    Yet the issue was the same: an implementation problem of the PCIE 4.0 specs for first-generation platforms. But thank you for feeling it necessary to respond with the simplistic obviology.
  • Spunjji - Thursday, April 29, 2021 - link

    Given how none of that second paragraph was relevant to this article, you look suspiciously like you're repeating keywords to maintain the prevalence of specific, already-resolved issues pertaining to Intel's competitors in search-engine rankings. What a mess.
  • JVC8bal - Friday, April 30, 2021 - link

    Actually, after doing a RMA on 3 of these boards to find the problem, I felt inclined to respond to the review. Others might be having this same issue. They will just need to update to the latest BIOS to avoid crashes with that combination of hardware. I don't why people like you feel the need to respond with conspiracy theories.

    Sorry, man--but I installed a PCIe4 5700XT into my x570 Aorus Master back in July 2019--about 21 months or so. And I've never--not even once--had any of the problems you allude to...;) It's been solid as a rock. Someone has badly misled you--it's just common old anti-AMD FUD. Very immature hogwash.
  • JVC8bal - Friday, April 30, 2021 - link

    Google "whea-logger and pcie 4". x570 was the first platform to experience this manifestation of the problems This was helpful in identifying the problem of specific gen4 NVMe drives conflicting with gen4 graphics cards. Speaking of immature, what a response... not just words, but the logic: somehow your 1-off, personal experience is indicative over broader reality? It's anti-AMD propaganda?
  • TheinsanegamerN - Friday, April 30, 2021 - link

    "I dont have a problem therefore the problem does not exist and anyone who says otherwise is immature, look how mature and sohpisticated i am! My farts smell like cinnamon!"

    Is that with all the necessary security patches applied? AMD processors are more secure than their Intel competitors right now. AMD also offered PCIe 4.0 for nearly two years before Intel got in on the act. Finally, AMD CPUs are simply more efficient.
    Three for the search engines to chew on.
