A new teardown of Intel’s Arc Pro B70 gives an early look at the design behind its Battlemage workstation GPU, and while the teardown stops short of exposing the silicon itself, it still reveals key details about the cooler, PCB layout, and firmware information tied to the card.
TechPowerUp Forums shared the teardown, where moderator Solaris17 disassembled the reference Arc Pro B70 and documented the internal layout, giving a closer view of how Intel has built this workstation-focused GPU.
Blower cooler and PCB design
The teardown shows that Intel uses a blower-style cooler instead of a blow-through design, and this setup pushes air directly out through the I/O bracket while keeping the heatsink shorter than the full shroud length, which aligns with typical workstation cooling priorities where controlled airflow matters more than open-air designs.
The images also confirm that the power cable is soldered directly onto the PCB, which is common in professional GPUs and accelerators where stability and reliability matter more than modularity.
Firmware details and hardware identification
The firmware dump included in the teardown identifies the card with device ID E223, along with a SOC4 hardware SKU and A0 stepping, which matches existing PCI database entries linked to the Battlemage G31 chip and Arc Pro B70.
Intel lists the Arc Pro B70 with 32 Xe-cores, 32GB of GDDR6 memory, 608 GB/s bandwidth, and a power range between 160W and 290W, with its reference card rated at 230W, and while the teardown gives a solid look at the board, the actual GPU package remains hidden until someone removes the cooler.
