This article covers PowerColor AMD Radeon RX 6800 XT搭載 グラフィックスカード オリジナルファンモデル RED DRAGON [AXRX 6800XT 16GBD6-3DHR.

Overview

The PowerColor Red Dragon AXRX 6800XT 16GBD6-3DHR/OC is a custom-cooled AMD Radeon RX 6800 XT graphics card equipped with 16GB of GDDR6 memory. With 4,608 stream processors and boost clocks reaching up to 2310MHz in OC mode, it delivers strong 1440p and capable 4K gaming performance. The card features a dual-BIOS switch, letting you toggle between a performance-oriented OC profile and a quieter Silent mode. Released in late 2020, this card remains a solid choice in the mid-high tier segment. Its 16GB VRAM gives it an edge in modern titles that consume more memory, and the PowerColor triple-fan cooler keeps temperatures in check even under sustained loads. The 12+2 phase VRM design ensures stable power delivery, contributing to long-term reliability. Priced around ¥130,000 on Japan, it offers compelling value for gamers who want high frame rates without jumping to the latest generation. Primary competition comes from NVIDIA GeForce RTX 3080 and RTX 4070 series cards.

Compatibility Guide

Slot Interface: PCIe 4.0 x16 (backward compatible with PCIe 3.0). Power Requirements: Recommended PSU 650W minimum, with two 8-pin PCIe power connectors. Physical Dimensions: Approximately 320mm length and 2.5 slots thick. Ensure your case has sufficient clearance, especially in small form factor builds. Display Outputs: 3x DisplayPort 1.4a + 1x HDMI 2.1, supporting up to 8K output.

Product Info

Launched in October 2020. Warranty: 2 years from authorized resellers. GPU: AMD Radeon RX 6800 XT (RDNA 2, 7nm). Memory: 16GB GDDR6, 256-bit bus, 512 GB/s bandwidth. TDP: 300W, typical gaming power draw around 250-280W. Market position: upper mid-range to high-end, excelling at 1440p high-refresh gaming.

Best Use Cases

1440p High Refresh Rate Gaming: The RX 6800 XT easily drives 1440p 144Hz+ monitors in most titles, with VRAM headroom for high texture quality. VR and Multi-Monitor Setups: With three DisplayPort and an HDMI 2.1, you can run multiple high-resolution displays smoothly. * Budget-Conscious High-End Builds: If you want near-flagship performance without paying flagship prices, this card offers excellent price-to-performance versus NVIDIA counterparts. ## Alternatives
NVIDIA GeForce RTX 3080 (10GB/12GB): Direct competitor; RTX 3080 has better ray tracing, but the RX 6800 XT's 16GB VRAM future-proofs against high-resolution texture packs. Price often favors the AMD card. Ray tracing performance is noticeably behind, so if that matters, consider RTX. NVIDIA GeForce RTX 4070: Newer architecture with DLSS 3.0 but only 12GB VRAM. For pure rasterization at 1440p, the 6800 XT often matches or beats it, and the extra VRAM helps in modded or heavily textured games.

Things to Consider

Ray Tracing: RDNA 2 ray tracing is a first-generation implementation; it's adequate but not competitive with NVIDIA's offerings in heavy RT scenes. If ray tracing is a priority, a current-gen NVIDIA card is preferable. Power and Heat: 300W TDP means adequate case airflow is essential. Pair with at least a 750W PSU for headroom. The card runs warmer than some newer designs, but the Red Dragon cooler performs well. Age and Availability: This card is several years old; new stock may be limited. Be cautious of used cards that might have been mined on. Buy from reputable sellers with warranty. Missing Features: No AV1 encoding, and no HDMI 2.1? Actually HDMI 2.1 is present. But no DisplayPort 2.0. Not a major issue for most users. * Potential Overkill: For 1080p gaming, this card is overpowered; consider RX 6700 XT or RTX 4060 Ti to save money.
