ASRock RX6950XT OCF 16G graphics card

16GB GDDR6 RDNA 2 GPU

The ASRock RX6950XT OCF 16G is a Radeon RX 6950 XT graphics card built on the RDNA 2 architecture with 16GB of GDDR6 memory across a 256-bit bus. It targets enthusiasts who want high-frame-rate 1440p or entry-level 4K gaming and need the headroom of 18 Gbps effective memory speed. The PCI Express 4.0 interface and 5120 stream processors provide the throughput for modern DirectX 12 Ultimate titles. Dual BIOS lets users choose between two factory profiles without flashing firmware.

Dual BIOS clock behaviour under load

The card ships with two BIOS positions labelled P and Q that define distinct clock envelopes. In P BIOS the boost clock reaches up to 2495 MHz and the game clock up to 2279 MHz, while Q BIOS tops out at 2310 MHz boost and 2100 MHz game clock. Under sustained workloads the higher P profile will draw more power and generate more heat, so the triple-fan cooler must dissipate up to 335 W continuously. Selecting Q BIOS trades peak frequency for lower thermal output during long sessions.

Triple-fan cooler and three 8-pin power inputs

A triple-fan design with striped axial fans and an all-metal cover moves air across a large heatsink while the 0dB silent cooling mode stops the fans at low temperatures. Three 8-pin PCIe power connectors feed the 335 W TDP, requiring a 1000 W power supply. The 332 mm length and 13.07 inch height dictate case clearance, and the rear bracket offers one HDMI 2.1 plus three DisplayPort 1.4 outputs for up to four 7680 x 4320 displays.
