ASRock Rack TRX40D8-2N2T

The ASRock Rack TRX40D8-2N2T is something truly innovative. The ATX form factor board eschews conventional gaming ornamentation common of its AMD Ryzen Threadripper motherboard contemporaries. Instead, ASRock rack continues in the theme of its ASRock Rack X570D4I-2T and builds a server-focused platform around a high-performance AMD Threadripper chip. The result is surprisingly good for what it hopes to accomplish, a marriage of the best of the workstation with server features.

ASRock TRX40 Taichi

Featuring support for no fewer than six M.2 Key-M solid-state drives and a deluxe thermal solution, the TRX40 Taichi looks promising if not for gamers (third-generation Threadripper is a mighty overkill platform for that use alone) then for pro content creators and serious storage-speed mavens. But I found that its minor creature-comfort flaws for builders, while relatively few, knock it down a bit, in light of the lofty price.

We pored over the specs to see if anything changed, and even asked Asus PR, only to be given a vague description of the Zenith II Extreme Alpha being better-optimized for extreme overclocking. We looked for even the slightest alteration, and finally came across a tiny update: While the original Zenith II Extreme had sixteen 70A MOSFETs, the new one is fitted with Infineon TDA21490 90A parts.

Gigabyte optimized its TRX40 Aorus Xtreme for four graphics cards at double-slot spacing, differing from the Asus board which has a single space between the second and third slots. While that might seem like a win for Gigabyte, moving the first slot to the case’s top position meant sliding up the DIMMs as well, which in turn limits the amount of space available for voltage regulator cooling.

Asus’ $849.99 ROG Zenith II Extreme is the company’s prime-time motherboard for AMD’s new third-generation TRX40 Ryzen Threadripper processors like the core-monster Threadripper 3970X. This board combines an abundance of overclocking features with a tasteful yet flashy exterior to create something that will appeal equally well to performance extremists, overclockers, and gamers willing to spill a few thousand dollars on a new PC.

The master follows an impressive 16+3 phase digital power design already is a good indication of that, that’s would be 16x 70amp phases. This board offers a 5 Gbe LAN jack as well as a single Gigabit one and also has been fitted with WIFI 6 (802.11ax) for Gigabit wireless performance that would offer 5.5x higher throughput compared to the 802.11ac 1×1 standard.

That said, the Xtreme’s heatsink arrangement isn’t as robust as Asus’. The pair around the CPU socket connect to one another via an 8mmn heatpipe, but there’s no further linking down to the chipset. On closer inspection, however, there’s a small fan inside the bottom edge of the I/O-side heatsink, helping keep things cool(er). It will be interesting to see how VRM temps compare amongst these premier TRX40 boards.

Vendors are all competing at price points well above £600 which culminates in motherboard options filled to the brim with the features that almost anybody could wish for. ASUS’ ROG Zenith II Extreme was no exception to that point. However, ASUS has taken the fight up a notch by releasing an updated ‘Alpha’ model which is buffed-up with a set of sixteen 90 Amp power stages.

MSI Creator TRX40

At the bottom of the board is four full-length PCIe 4.0 slots which run at x16/x8/x16/x8, with two PCIe 4.0 M.2 slots complimented with a long M.2 heatshield which sits between the bottom two PCIe 4.0 slots. A third M.2 slot is located vertically along the right-hand side of the board just above the actively cooled chipset heatsink.
