Overview
Deploying 32GB of high-density GDDR6 memory across a 256-bit bus, MAXSUN’s implementation of the Intel Xe2-HPG architecture targets memory-intensive workstation compute and local AI acceleration. Operating 32 Xe cores at a base clock of 2600 MHz with a 2800 MHz maximum boost, the processor yields 608 GB/s of dedicated bandwidth while interfacing over a high-throughput PCIe 5.0 x16 connection. Modern display pipelines are fully accounted for via three DisplayPort 2.1 connectors and a single HDMI 2.1a port, ensuring expansive multi-panel or high-refresh visual workflows directly from the rear bracket.
Physical construction adheres strictly to professional rack and workstation enclosure requirements. Measuring 10.51 x 4.37 x 1.52 in (267 x 111 x 38.65 mm), the card occupies a disciplined dual-slot envelope reinforced by a full-length metal backplate to resist structural deflection. Thermal dissipation is managed by a lateral turbo blower mated to an integrated vapor chamber base, funneling waste heat directly through the rear exhaust plate rather than recirculating warm air inside the host chassis. This configuration maintains thermal isolation in dense multi-GPU configurations, even as the 290W total board power demands consistent airflow and a dedicated 12V-2×6 power connection.
