Overview
Dual Intel Xe2 Battlemage BMG-G21 graphics processors occupy a single 300 mm printed circuit board, establishing a high-density compute architecture tailored for parallel AI inference and compute workloads. Delivering an aggregate 48 GB of GDDR6 memory divided into 24 GB dedicated pools per GPU, the hardware incorporates 40 Xe cores, 320 XMX engines, and provides up to 394 INT8 TOPS of peak compute. Board electrical routing channels power through a single 16-pin 12V-2×6 connector rated for 600 W, safely covering the unit’s 400 W total board power requirement. However, the architectural design omits an onboard PCIe switch or PLX bridge chip; the card relies entirely on host motherboard PCIe 5.0 x8/x8 bifurcation to expose both discrete B60 processors over a single physical x16 slot.
Thermal dissipation across the dual GPU dies is managed by an enclosed lateral blower assembly within a standardized dual-slot profile. This radial blower configuration directs exhaust air through the rear chassis bracket, making the 300 mm enclosure compatible with multi-GPU workstation chassis and dense rackmount environments where up to four cards can be arranged in parallel Battlematrix configurations. Under maximum 400 W sustained board loads, directional high-static-pressure airflow prioritizes thermal evacuation over acoustic minimization, resulting in audible fan noise typical of enterprise blower designs. Because acoustic sound levels and peak junction temperatures under continuous load have not been published in laboratory benchmarks, long-term thermal behavior is anchored by the mechanical airflow constraints of the dual-slot blower format.
Deployment requires careful host platform validation due to the card’s strict bifurcation requirement. If installed in a PCIe slot lacking x8/x8 bifurcation support in the motherboard UEFI, only the primary GPU initializes, cutting usable memory and compute in half. In fully bifurcated workstation environments with contemporary Intel driver stacks, the card functions as two independent discrete graphics processors recognized by runtime environments for parallelized AI workflows. The integration of high-density GDDR6 capacity without triple-slot bulk delivers significant utility for local inference servers, provided system builders account for the 400 W thermal exhaust and motherboard signaling requirements.
