ASUS TUF Gaming Radeon RX 7900 XT OC 20 GB
Navi 31 XT / RDNA 3 (2022). This record describes the named add-in-board variant and its published configuration, not every RX 7900 XTX/XT board. Verify its exact product label, revision and manufacturer document before installation or service.
MODEL / SKU: TUF-RX7900XT-O20G-GAMING — TUF Gaming OC 20 GB GDDR6. Board-partner clocks, PCB, cooling, output bracket and BIOS are distinct from AMD's reference design.
Recorded board specifications
| Cataloged board / exact SKU | ASUS TUF Gaming OC 20 GB GDDR6; TUF-RX7900XT-O20G-GAMING. |
|---|---|
| GPU / architecture / launch | Navi 31 XT / RDNA 3 (2022); Navi 31-family GPU. |
| GPU resources | 5,376 stream processors; product clocks are factory/BIOS-profile dependent and are intentionally not generalized across revisions. |
| Memory / bus | 20 GB GDDR6 at 20 Gb/s on a 320-bit interface (800 GB/s raw bandwidth); 80 MB Infinity Cache. |
| Host interface | PCI Express 4.0 x16 physical/electrical board interface. Link speed and lane operation depend on host, firmware, slot wiring and negotiated link. |
| Board power / auxiliary input | AMD reference RX 7900 XT board power is 315 W. ASUS TUF product uses three 8-pin PCIe power connectors; consult its manual for PSU capacity and selectable performance BIOS specifics. |
| Dimensions / cooler envelope | 352.9 × 158.2 × 72.6 mm (length × height × thickness), 3.63-slot class cooler. Allow additional chassis and cable clearance; dimensions are the partner listing, not a guarantee for every production revision. |
| Display outputs | 2 × HDMI 2.1 and 2 × DisplayPort 2.1. Output versions, simultaneous-display limits and supported modes depend on firmware, driver, cables and display. |
| Revision / fit caveat | Cataloged O20G TUF SKU. Check BIOS selector position, PCB/cooler revision and label; dimension/case-fit should be measured on the actual sample and include the power-cable bend. |
Compatibility, service & revision notes
Check the model/SKU suffix and PCB or cooler revision against the card label before purchasing power leads, a replacement cooler or a firmware image. Fit is governed by measured card length, height, thickness, adjacent-slot obstruction, case structure and power-lead bend space—not by the slot count alone. Partner power limits and factory overclock profiles may differ from AMD reference specifications.
- Use the power connectors and PSU capacity in the exact partner manual; fully seat the plugs and do not adapt or force damaged connectors.
- Record serial/part labels, subsystem ID, BIOS switch position, driver version and physical condition. Do not flash a ROM unless it explicitly matches the board revision and subsystem.
- Confirm the supported OS/driver branch and display-output capability for the intended platform; link generation negotiates with the host but does not resolve firmware or power incompatibility.
