This article covers PowerColor Red Devil AMD Radeon RX 6900 XT Ultimate ゲーミンググラフィックスカード 16GB GDDR6メモリ付き AMD RDNA 2 HDMI 2.1搭載.
Overview
The PowerColor Red Devil AMD Radeon RX 6900 XT Ultimate is a high-end graphics card based on AMD's RDNA 2 architecture. It features 16GB of GDDR6 memory and 5120 stream processors, delivering exceptional performance for 4K gaming and creative workloads. The boost clock reaches up to 2425MHz, and memory speed is 16.0Gbps. The large triple-fan cooler ensures efficient thermal management even under heavy loads. Released in 2021 as a factory-overclocked variant of the RX 6900 XT, this card outperforms the reference model with higher clock speeds. It competes directly with NVIDIA's RTX 3080 and RTX 3090 in 4K gaming, and the 16GB VRAM is well-suited for high-resolution textures and creative applications. HDMI 2.1 support enables 4K 120Hz output. Positioned at the very top of the consumer GPU market, this card targets enthusiasts who demand the best performance. With a 300W TDP, a robust power supply is essential.
Compatibility Guide
The card uses a PCI Express 4.0 x16 interface and requires three 8-pin power connectors. A 700W or higher power supply is recommended (850W for peak loads). It occupies three expansion slots and measures approximately 320mm in length, so check your case clearance carefully. Memory is 16GB GDDR6 on a 256-bit bus with 512GB/s bandwidth. It includes 80 ray accelerators and supports AMD FSR (FidelityFX Super Resolution) for improved frame rates in supported games.
Product Info
Released in 2021, this card is available through major retailers like . Pricing is in the high-end segment, currently around ¥147,624 (tax included). Warranty is typically 2 years from PowerColor. This is a high-tier product designed for 4K gaming, video editing, and 3D rendering. The triple-fan cooler keeps temperatures in check, allowing sustained performance.
Best Use Cases
4K Gaming at Maximum Settings: The RX 6900 XT Ultimate delivers smooth frame rates in demanding titles at 4K resolution, especially in first-person shooters and open-world games. Content Creation: With 16GB VRAM, it handles 4K video editing, 3D rendering, and large texture projects efficiently. It supports AMD's HIP and OpenCL for compatible software. * AMD Ecosystem Builds: Combined with a Ryzen CPU, Smart Access Memory boosts performance in many games, making it an excellent choice for an all-AMD system.
Things to Consider
The card's size and weight require a spacious case and strong support (consider a GPU bracket). Power consumption is high at 300W, so a quality 700W+ PSU is mandatory. Ray tracing performance falls behind NVIDIA's RTX 30-series cards, so if ray tracing is a priority, competing options may be better. Availability and pricing can fluctuate, so compare current market prices before purchase.
