Benchmark Testing

With the technical specs out of the way, the Z790 Aorus Elite AX is clearly a well equipped motherboard. Gigabyte also have even higher-end ones out there but this one is really great. There are a tonne of features here that any self-respecting gamer would certainly love, especially the onboard 802.11ax Wi-Fi 6E with a new dedicated 6GHz band.

Unboxing the motherboard, users will see that this is quite a sturdy product, with a lot of heatsinks and clean lines everywhere. The motherboard not only looks great but it also performs great – which we’ll get to that shortly. The experience of installing the Z790 Aorus Elite AX into our test bench chassis (A Corsair Carbide 678C) was super easy. The motherboard aligned perfectly and screwing it into place was pretty much effortless. Gigabyte have labelled everything quite clearly on the motherboard itself and plugging in all the respective cables and any additional hardware was straightforward.

The Gigabyte Z790 Aorus Elite AX supports DDR5 RAM, so we installed 2 sticks of 16Gb DDR5-5200 Gigabyte RAM, alongside our AMD RX590 GPU and Gigabyte AORUS WATERFORCE 240 All-in-One cooler. Of course, being a 13th-gen motherboard we also needed to install a brand new 13th-gen Intel CPU. We used the top-of-the-range Intel i9-13900K and were absolutely blown away both by the CPU’s performance and by the motherboard’s ability to perform under pressure.

To kick off our benchmark testing, we picked a video game still played by thousands today, despite having released a decade ago – Counter-Strike: Global Offensive. It’s an intensely CPU-bound game that has been benchmarked extensively so we wanted to see how it would perform on the latest hardware. The results speak for themselves and we obtained 248 to 325 FPS in-game quite easily. Even hitting a high of 360 FPS at one point – pushing the limit of the latest displays.

Next up was another classic – 3D Mark’s CPU test. The Intel i9-13900K chewed through this at a blistering pace and yielded the following results.

Notably, and perhaps unexpectedly, the CPU barely even struggled with this and each test performed was completed ridiculously fast. To test this further, we also ran Cinebench R23’s single-core and multi-core tests which resulted in an amazingly high score – one which quite literally topped the charts.

Before all of our benchmarking tests, we took a screenshot of the motherboard’s temperatures with our test bench idling. The system ran quite frosty, well below 50 degrees Celsius.

After torture testing the system for 15 minutes with Prime 95, the temperatures ran quite hot with the CPU reaching a high of 99 degrees Celsius. Parts of the motherboard never exceeded temperatures higher than 52 degrees though, which tells us that the heatsinks and all the gorgeous Thermal Guards and Thermal Pads are doing their job exceedingly well in keeping the temperatures under control and spikes confined to their respective components.

Also, as soon as we stopped the testing, both the CPU and the motherboard’s temperatures normalised extremely fast, almost dropping back down to the idle temperatures immediately.

Additionally, we ran these benchmark tests during a heatwave so the ambient temperature around us was already quite warm at ~32 degrees Celsius. The fact that the Z790 Aorus Elite AX managed to keep itself cool under pressure and still normalise the temperatures so quickly after the testing tells us that this board is performing extremely well. The thermals across the board were great and while we couldn’t test some features in far more detail given our limited time with the board, it operated perfectly over several days of successive stress tests. The Gigabyte Z790 Aorus Elite AX is, therefore, a fantastic motherboard when it comes to thermal performance.

The motherboard’s I/O is great and an improvement over the Z690 Gaming X we reviewed earlier this year since it has built-in WiFi with a magnetic stand antenna too. Gigabyte have also revamped their Aorus Engine into the new “Gigabyte Control Center” and we love that there’s been a change to a better software suite now.

The only gripe we have with the motherboard is the fact that the middle NVME heatsink had a bit of a wobble to it. We’re not exactly sure if this was just the review sample we had or if this occurs on production units too but we’ve reached out to Gigabyte to provide us with some clarity on this and will update this review accordingly once we receive feedback. (UPDATE: After double checking with Gigabyte, the heatsink only wobbles when there isn’t an NVME installed underneath it. When an NVME is installed, it remains in place and there is no longer any wobble. Thus, we don’t have any negatives anymore. This is a solid motherboard and one that we can recommend to anyone looking to upgrade)

Overall, the Gigabyte Z790 Aorus Elite AX is a fantastic motherboard if you’re in the market for a 13th-generation Intel motherboard. Given the high price of upgrading, as well as the drawbacks of the 13th-gen CPU’s power draw and high thermals though, if you’re still running 11th-generation or even 10th-generation systems, we’d suggest maybe holding off on an upgrade unless you desperately need to.

There is also the elephant in the room to consider, which is AMD’s competing AM5 Ryzen CPUs. Intel’s Core i9-13900K has 24 cores (8 + 16) and supports up to 32 threads, while AMD’s best CPU uses the more traditional 16-core and 32-thread layout. Both of these CPUs are almost on equal footing with AMD’s being slightly more expensive as a drawback, while having a lower TDP than Intel’s 13th-gen running in Turbo mode. The i9-13900K, however, still takes the top spot with multi-core applications, while AMD’s CPUs are more suited to applications that rely on individual cores. Pricing between the two tech giants is going to be a key factor to consider as well as the types of applications that you’re planning on running. Users are therefore advised to do some extensive research into both new generations of CPUs so that they can plan their builds accordingly.

Final Verdict

Ultimately, if you’re looking for a motherboard that can handle the heat generated by Raptor Lake CPUs as well as deal with its higher power draw, the Gigabyte Z790 Aorus Elite AX is definitely a board to consider. Retailing for around R6,999 at the time of writing this review, this also places it at a sweet spot for would-be buyers when compared to much of the competition out there.
