What Gigabyte announced
Gigabyte's board targets AMD Ryzen Threadripper PRO 9000 WX and 7000 WX processors. VideoCardz reports it was shown at Computex 2026 in June, and it now has a dedicated product page with technical documentation and BIOS downloads. Notebookcheck says it uses AMD's WRX90 chipset and the sTR5 socket.
This is not a desktop board with delusions of grandeur. It is a registered-ECC, eight-channel, remote-managed workstation platform. Gigabyte's AI TOP branding is aimed at people running local AI training and inference.
The 2 TB figure
The board has eight DDR5 RDIMM slots across eight memory channels, supporting up to 2 TB of ECC memory. Three points matter here:
- It is a ceiling, not a bundle. No memory ships with the board.
- It needs registered ECC DIMMs. Ordinary desktop UDIMMs won't work.
- Usable memory can be a bit lower than the installed amount, as with any system that reserves some RAM for itself.
Per the supplied reporting, reaching 2 TB means one DIMM per channel using very high-capacity modules. Memory prices are a separate budget line from the board.
The cooling claim
The board carries Gigabyte's DDR Wind Blade XTREME Duo. It uses two fans to push air across the memory slots, and Gigabyte says it can cut memory temperatures by up to 43 °C. The VRMs and chipset are also actively cooled to help with stability under sustained loads.
Treat the 43 °C figure as a marketing claim. The material I reviewed doesn't state the baseline, the test conditions, or the memory configuration, and it has no independent validation. "Up to" also means a best case. Dense RDIMMs do run warm, so active airflow is plausible, but how much it helps is unproven.
PCIe slots and the nine-GPU claim
Seven full-length PCIe 5.0 slots connect directly to the processor. Six run at x16 and the seventh at x8. Two MCIO 8i connectors add more PCIe devices and storage expansion.
Here is where "nine GPUs" comes from. At Computex, Gigabyte demonstrated a configuration supporting up to nine GPUs by connecting two additional graphics cards externally. So:
- It is seven in-board slots plus two externally attached cards via MCIO.
- It does not mean nine slots, and nine cards won't fit in a normal tower.
- The reporting doesn't detail the cabling, enclosure, or which GPU models work.
Anyone planning a build should also think about card thickness and slot spacing, power delivery, and cooling for the cards themselves. The board can't solve those problems.
Storage and lane sharing
Notebookcheck lists a 32+3+3+3-phase power design with 110 A power stages and a 14-layer PCB. Storage includes two PCIe 5.0 M.2 slots, one PCIe 4.0 M.2 slot and four SATA ports. The catch: one MCIO connector shares bandwidth with the two PCIe 5.0 M.2 slots, so those connections cannot all be used simultaneously.
If you want fast NVMe scratch storage and MCIO-attached accelerators, plan the lane budget first. Treat that sharing note as Notebookcheck's reporting, since I couldn't confirm it independently from Gigabyte's own documentation.
Networking, management and OS support
- Networking and I/O: dual Intel X710 10GbE, two USB4 Type-C ports and six rear USB 3.2 Gen 2 ports.
- Remote management: an ASPEED AST2600 controller for IPMI. This lets admins monitor and manage the machine remotely.
- Operating systems: Windows 11 and Ubuntu 24.04 LTS, plus Gigabyte's AI TOP Utility for local AI computing.
For IT admins, the BMC is the practical draw. It makes a multi-GPU box far easier to run in a rack or a back room.
Size, price and availability
The board measures 305 × 330 mm and is E-ATX. Check case support before buying, since not every E-ATX case fits a board this deep. Per Notebookcheck's October 23 coverage, Gigabyte had not announced pricing or a retail date. I found no confirmed street price, so don't assume one. For context only, third-party roundups put other WRX90 boards in roughly the $1,150–$1,470 range. That is not a forecast for this one.
Bottom line
The WRX90 AI TOP looks like a capable platform for local AI work, with eight-channel ECC memory, plenty of PCIe 5.0, remote management and Windows 11 support. The three big claims need reading carefully:
- 2 TB is a maximum.
- The 43 °C cooling figure comes from Gigabyte and has no stated test method.
- Nine GPUs was a demonstration with external connections, not nine slots.
Until pricing, benchmarks and independent thermal tests arrive, it is a promising spec sheet rather than a proven buy.
Update: Additional details (November 4, 2026)
Club386 reports that the WRX90 AI TOP supports ECC RDIMMs and 3DS RDIMMs, with memory overclocking profiles rated up to 7,800 MT/s. It also lists two 8-pin CPU power inputs alongside the 32+3+3+3-phase power design and 14-layer server-grade PCB.
The outlet additionally identifies a front-panel USB 3.2 10Gbps Type-C header, two Mini DisplayPort outputs, and a microSD card slot among the board’s I/O.
