Professional graphics card
The GUNNIR Arc Pro B70 TF is a workstation-class GPU built on Intel Arc architecture with 32 Xe cores and 32GB of GDDR6 memory. It targets creators, engineers and developers who need large frame buffers for rendering, simulation and AI inference workloads. The 256-bit memory interface and 608 GB/s bandwidth support high-resolution assets and large datasets.
Display connectivity
Four modern outputs — three DisplayPort 2.1 and one HDMI 2.1 — drive up to 7680 x 4320 resolution across multiple panels for colour-critical workflows. The card occupies a dual-slot footprint measuring 267 x 111.1 x 37.3 mm and draws auxiliary power through two 8-pin connectors. A metal backplate and reinforced bracket add structural rigidity inside workstation chassis.
Thermal and power profile
A turbo fan cooling system manages the 290 W total board power while the GPU runs at 2600 MHz graphics clock. The TSMC N5 process helps contain heat density across the 32 Xe cores during sustained compute tasks. Fan speed ramps with load, keeping acoustic output proportional to workload intensity. The PCI Express 5.0 x8 interface provides ample host bandwidth without saturating the power budget.
