This article covers Sapphire 11308-13-20G 有毒 AMD Radeon RX 6900 XT 液体冷却 PCIe 4.0 ゲーミンググラフィックスカード 16GB GDDR6付き.

Overview

The Sapphire TOXIC series has long been the flagship line for the brand, and the Sapphire 11308-13-20G TOXIC AMD Radeon RX 6900 XT Liquid Cooled edition lives up to that reputation. As the name suggests, this is a factory-fitted liquid-cooled graphics card built around the AMD Radeon RX 6900 XT GPU. Powered by the RDNA 2 architecture and built on a 7nm process, this card features 16GB of GDDR6 memory and supports PCI-Express 4.0. The boost clock reaches up to 2365MHz, with a game clock of up to 2135MHz. A one-click TOXIC boost feature can push the clock all the way to 2600MHz, making it one of the fastest air-to-liquid cooled cards on the market. This card is designed for enthusiasts who demand the best in 4K gaming, VR, and creative workloads like video editing and 3D rendering. It sits firmly in the high-end tier, offering a compelling alternative to NVIDIA's RTX 3080 Ti and RTX 3090.

Compatibility Guide

Interface: PCI-Express 4.0 x16 (backward compatible with PCI-Express 3.0, though 4.0 is recommended for full bandwidth). Video outputs: DisplayPort and HDMI, supporting multi-monitor setups. Power supply: Minimum 700W recommended, with 850W or higher being a safer choice for overclocking and system stability. Standard 8-pin PCIe power connectors are required (no 12VHPWR). Physical fit: The card itself is large, and the included liquid cooling radiator (likely 360mm class) requires ample space in your case. Always check your case's radiator support and GPU length clearance before purchasing.

Product Info

The Sapphire 11308-13-20G TOXIC AMD Radeon RX 6900 XT Liquid Cooled was released in late 2021 as a premium high-end offering. Its market position is clearly at the top, targeting users who want higher clocks and better thermal performance than air-cooled models can provide. GPU: AMD Radeon RX 6900 XT (Navi 21, RDNA 2.0, 7nm) Memory: 16GB GDDR6, 256-bit bus, 512 GB/s bandwidth Boost clock: Up to 2365MHz (up to 2600MHz with TOXIC boost) Game clock: Up to 2135MHz Memory clock: 16 Gbps (default) TDP: 300W Outputs: DisplayPort, HDMI Warranty: Standard manufacturer warranty (check Sapphire's official site for details)

Best Use Cases

4K gaming at max settings: This card delivers smooth 60+ fps in most titles at 4K with ultra settings. It's ideal for gamers who want to play demanding games like Cyberpunk 2077 or Fortnite at the highest visual quality. Users new to liquid cooling: The factory-integrated liquid cooling system means you get the benefits of water cooling without the complexity of building a custom loop. Maintenance is minimal. Creative professionals: The 16GB VRAM buffer is excellent for 4K video editing, 3D modeling, and AI workloads that require large memory pools. Who should NOT buy this: If you only play lightweight 1080p games, are on a tight budget, or need a compact card for a small form factor build, this is overkill and not a good fit. ## Alternatives
Direct competitors in the same price tier include the NVIDIA GeForce RTX 3080 Ti and RTX 3090. The RX 6900 XT generally excels in rasterization performance, often beating the RTX 3080 Ti in non-ray-traced games. However, NVIDIA cards have the edge in ray tracing performance and the CUDA ecosystem. Compared to air-cooled RX 6900 XT models, this TOXIC liquid-cooled variant runs cooler and maintains higher boost clocks under sustained load, making it better for long gaming sessions or rendering jobs. The trade-off is a higher price and larger physical footprint.

Things to Consider

This card is physically large and requires a case that supports a 360mm radiator. Measure your case carefully before buying. Pricing has fluctuated since launch; you may find deals on new old stock or used units, but check warranty and condition thoroughly. Ray tracing performance lags behind NVIDIA's equivalent generation, so if ray tracing is a priority, an RTX 3080 Ti or RTX 3090 may be a better choice. A high-quality power supply with sufficient headroom is essential. 850W or more is recommended for a stable system, especially if you plan to overclock. ## FAQ Q: Can I use this card with a PCI-Express 3.0 motherboard? A: Yes, it is backward compatible. However, bandwidth is halved compared to PCIe 4.0, which may cause a slight performance drop in theory. In practice, the difference is minimal for most games, but a PCIe 4.0 motherboard is recommended for optimal performance. Q: Does the liquid cooling unit require maintenance? A: The unit is designed to be maintenance-free. However, it's a good idea to periodically clean dust from the radiator and check that the fans are spinning properly. Coolant replacement is not required. Q: Can this card handle 4K 144Hz gaming? A: It depends on the game and settings. Many titles will run at 4K 60fps or higher with ease, but consistently hitting 144fps at max settings is challengi
