- Broad hardware media engine supporting AV1, H.265, and H.264 encode/decode
- Modern PCIe 5.0 host interface with DisplayPort 2.1 connectivity

- HDMI 2.1 display outputs bandwidth-limited to 7680 x 4320 @ 30Hz
Overview
Drawing all operating power directly from the motherboard PCIe slot within a strict 70W Total Board Power envelope, the Intel Xe2 microarchitecture on TSMC’s N5 process node integrates 16 Xe cores clocked at 1700 MHz without requiring auxiliary 12V power cabling. Pairing this silicon with a 16GB GDDR6 memory configuration across a 128-bit bus generates 224 GB/s of bandwidth and 170 INT8 TOPS of compute throughput. The host interface communicates over PCIe 5.0, feeding a multi-format media engine capable of hardware acceleration across AV1, H.265, H.264, VP9, VC1, and MPEG2. Display outputs provide a DisplayPort 2.1 connector supporting up to 7680 x 4320 @ 60Hz alongside dual HDMI 2.1 ports capped at 7680 x 4320 @ 30Hz.
Physical integration centers on a single-slot, low-profile footprint measuring 6.57 x 2.72 x 0.72 in (167 x 69 x 18.4 mm), engineered specifically for density-restricted 1U/2U server chassis and small form factor workstation enclosures. Thermal dissipation relies on a dedicated single-slot turbo blower cooling system designed to drive exhaust laterally across the low-profile bracket within an ambient operating envelope of 32°F to 113°F (0°C to 45°C). Maintaining active airflow within an 18.4 mm single-slot profile naturally requires higher blower rotational speeds under sustained compute workloads compared to dual-slot axial arrangements, but ensures adjacent expansion slots remain unblocked.
In practical workstation and homelab deployment, the inclusion of 16GB of addressable video memory alongside slot-powered operation fulfills specialized edge computing, AI model inference, and multi-stream video transcode requirements under DirectX 12 and OpenGL 4.6. Eliminating external PCIe power leads bypasses auxiliary connector failure modes and enables direct installation into proprietary OEM office systems. While the 128-bit bus width and 30Hz 8K HDMI ceiling represent clear architectural throughput limits, the overall assembly offers a compact, functional compute platform for space-limited configurations.
