Overview
Operating strictly within a 70 W PCIe slot power envelope, GUNNIR’s implementation of the Intel Xe2 Battlemage architecture packs 16 GB of ECC-supported GDDR6 memory into an ultra-compact single-slot profile. Built on TSMC’s N5 process node, the Arc Pro B50 silicon integrates 16 Xe cores, 16 ray tracing units, and 128 XMX engines delivering 170 TOPS of INT8 AI compute without drawing auxiliary power cables from the system PSU. The memory subsystem routes across a 128-bit bus clocked at 14 Gbps to achieve 224 GB/s of bandwidth, balancing board trace simplicity against sustained data throughput for edge inference and multi-stream media pipelines.
Measuring 6.57 x 2.72 x 0.72 in (167 x 69 x 18.4 mm), the physical card conforms to true low-profile single-slot mechanical tolerances, enabling drop-in integration into high-density 1U/2U rack servers, enterprise thin clients, and small-form-factor workstations. Thermal dissipation is handled by an enclosed single blower fan assembly exhausting warm air directly through the rear I/O bracket. While the compact blower impeller naturally operates at a higher acoustic pitch under sustained load than larger multi-slot axial fans, the card’s real-world power draw remains exceptionally modest at 50 W to 55 W under load, well below the 75 W PCIe slot limit and preventing thermal saturation inside cramped enclosures.
Display connectivity provides two HDMI 2.1 ports alongside a single DisplayPort 2.1 interface capable of driving up to 8K resolutions at 7680 x 4320. Media workflows benefit from comprehensive hardware acceleration across AV1, HEVC, H.264, and VP9 encode and decode blocks. Driver support targets DirectX 12 and OpenGL 4.6 workstation environments, where the 16 GB memory pool and hardware ECC capabilities shield long-running scientific simulations and local language model workloads against soft bit-flip errors, despite synthetic OpenCL performance trailing wider-bus consumer cards.
