Gigabyte adds 64GB AI TOP ATOM, but store lists later release

Gigabyte has announced a 64GB unified-memory version of its AI TOP ATOM desktop alongside the existing 128GB model, although its launch announcement and official store listing give different availability signals.

In a company release distributed through PR Newswire, datelined Taipei on 11 November 2026, Gigabyte said the 64GB version was available immediately. The supplied AORUS Official Store listing instead gives an expected release date of 24 December 2026 for the 64GB model with a 2TB SSD. Neither source establishes Australian pricing or local availability.

The release was published by PR Newswire at 10pm US Eastern Time on 10 November. Both the announcement and store listing are primary vendor material, rather than independent reporting or testing. The supplied material does not explain the difference between the availability dates.

According to Gigabyte, the two memory variants use the NVIDIA DGX Spark platform and share the same compact chassis design. The company is targeting AI developers, machine-learning engineers, researchers, educators and enthusiasts who want to choose a memory capacity for their work.

The store lists the 64GB configuration with an NVIDIA GB10 processor featuring 20 CPU cores, NVIDIA Blackwell graphics and LPDDR5x memory shared between the CPU and GPU. Storage is a single 2TB M.2 PCIe 4.0 NVMe SSD.

Gigabyte describes the machine as a platform for local AI development, fine-tuning and inference without relying on cloud services. Its store claims up to one petaflop of AI performance, but the supplied listing does not specify the numerical precision or testing conditions behind that figure. No independent performance measurements are included in the evidence.

The software configuration includes NVIDIA DGX OS. The store also describes a pre-integrated NVIDIA AI software stack and Gigabyte AI TOP Utility for model deployment, training and inference. Those are vendor descriptions of intended capabilities, not demonstrated customer outcomes.

The desktop measures 150mm wide by 150mm deep and 50.5mm high, with a listed weight of 1.2kg. Connectivity includes 10Gb Ethernet, Wi-Fi 7, Bluetooth 5.4, one HDMI 2.1a port and four USB 3.2 Gen 2x2 Type-C ports. The listing specifies a 240W power supply and a two-year warranty.

For prospective Australian buyers, the supplied sources leave the local release schedule unresolved. The announcement establishes Gigabyte's addition of a 64GB option, but does not confirm when that configuration will reach Australian customers.
