The RX 9070 XT Steel Legend runs AMD’s complete Navi 48 die at 64 compute units and 4096 stream processors — no disabled CUs, no binning compromise. Clock targets sit at AMD’s reference figures: 2970 MHz boost and 2400 MHz game clock. That’s a measured approach compared to factory-OC’d competitors, but the underlying silicon is identical — a clean reference-clocked card that leaves headroom for manual overclocking via AMD Adrenalin Edition software. The full RDNA 4 feature suite applies: 3rd-generation RT accelerators (AMD claims ~2× the ray intersection throughput of RDNA 3), 2nd-generation AI accelerators enabling FSR 4 ML-based upscaling, HYPR-RX, Fluid Motion Frames with Anti-Lag 2, hardware AV1 encoding, and 64MB of Infinity Cache supplementing the 256-bit GDDR6 bus.

Steel Legend Cooling — Striped Ring Fans, Ultra-Fit Heatpipes, Reinforced Frame

The triple-fan cooler spans ~2.9 slots with three fans running ASRock’s Striped Ring Fan blade design — optimised for high static pressure through the fin stack while keeping acoustic levels manageable at moderate loads. Ultra-fit heatpipes sit flush against the GPU die for efficient direct heat transfer, while Air Deflecting Fins channel airflow more precisely through the heatsink array. A reinforced metal frame runs along the card’s spine, stiffening the PCB against sag under the cooler’s weight — a meaningful structural addition at 298mm length and ~1.15kg. Fans stop entirely under low load for silent desktop operation, resuming as temperatures climb.

ASRock uses military-grade Super Alloy capacitors and chokes on the power delivery circuitry — rated for higher temperature tolerance and longer operational hours under load. A full-length metal backplate protects the PCB and adds a second layer of structural support.

Polychrome SYNC ARGB, 2× 8-pin, 3× DisplayPort

Integrated ARGB LEDs in the fan hubs and along the shroud are controllable via ASRock’s Polychrome SYNC software and can be synchronised with compatible ASRock motherboards. A hardware RGB toggle switch on the card edge lets you kill the lighting entirely without software — a practical feature for builds where lighting isn’t wanted. Note that third-party RGB software (OpenRGB) does not currently support this card’s lighting.

The output configuration is 3× DisplayPort 2.1a and 1× HDMI 2.1b — three DP outputs make this a better fit for triple-monitor or high-refresh-rate display setups compared to cards with a 2+2 split. Power delivery uses just 2× 8-pin PCIe connectors, making cabling simpler than the 3× 8-pin required by some competing 9070 XT models, while still managing the card’s TDP at reference clocks without issue in testing.

No factory OC, no Dual BIOS: The Steel Legend runs AMD reference clocks rather than a factory overclock, and does not include a Dual BIOS switch. Buyers wanting a higher out-of-box clock or a Performance/Silent BIOS toggle should consider the Gigabyte RX 9070 XT Gaming OC or ASRock’s Taichi model.

RGB software dependency: Polychrome SYNC RGB requires ASRock software for full control. OpenRGB does not currently support this card’s lighting. The hardware toggle switch on the card can disable lighting entirely without software.

PSU requirement: A quality 750W+ PSU is recommended with this card despite the 2× 8-pin connector configuration — the RX 9070 XT’s TDP under sustained gaming load is significant, and the rest of your system draws power simultaneously.

Case clearance: At 298mm length and ~2.9 slots, verify GPU clearance in your case before purchasing, particularly in mATX builds.
