This article covers Sapphire 11330-01-20G Nitro+ AMD Radeon RX 7800 XT ゲーミンググラフィックカード 16GB GDDR6 AMD RDNA 3.

Overview

The Sapphire Nitro+ series has long been recognized for its exceptional cooling and low noise levels among AMD Radeon graphics cards. The Sapphire 11330-01-20G Nitro+ AMD Radeon RX 7800 XT features the RDNA 3 architecture with a boost clock of up to 2565 MHz and 16 GB of GDDR6 memory on a 256-bit bus. This card is primarily designed for high-refresh-rate 1440p gaming, delivering stable frame rates even with ray tracing and high-quality settings enabled. Its triple-fan, 3-slot cooler keeps temperatures and noise in check, making it a strong contender in the mid-high GPU segment. Positioned against the NVIDIA GeForce RTX 4070, the RX 7800 XT offers more VRAM (16 GB vs 12 GB) at a similar price point, giving it an edge for memory-intensive games and creative workloads.

Compatibility Guide

The card uses a PCIe 4.0 x16 interface and is backward compatible with PCIe 3.0 slots with negligible performance loss. It occupies three expansion slots and measures 320 mm in length, so case clearance is critical—especially in mid-tower or smaller chassis. Power is supplied via two standard 8-pin PCIe connectors. A 650 W power supply is recommended, but for headroom and transient spikes, a 750 W unit is advisable. Memory type is GDDR6, and no special motherboard memory compatibility is required.

Product Info

Launched in August 2023, the Sapphire Nitro+ RX 7800 XT is a factory-overclocked custom model based on the AMD Radeon RX 7800 XT (Navi 32 chip, 5 nm process, RDNA 3 architecture). TDP is rated at 263 W. The boost clock is increased from the reference 2430 MHz to 2565 MHz. Memory runs at 19.5 Gbps effective, providing 624.1 GB/s of bandwidth across a 256-bit bus. The card features 3840 stream processors, 240 TMUs, 96 ROPs, and 60 ray accelerators. Market positioning is mid-high tier. It competes directly with the RTX 4070, offering superior VRAM capacity and competitive rasterization performance, though ray tracing lags behind NVIDIA's offering.

Best Use Cases

1440p Gaming Enthusiasts: This card excels at 1440p with high settings and high refresh rates. The 16 GB VRAM ensures future-proofing for texture-heavy titles and upcoming games. Silence-Oriented Builders: The Nitro+ cooler features a semi-fanless mode—fans stop completely under low load. Even under gaming load, noise levels remain impressively low compared to many competitors. * Content Creators on a Budget: For video editing, 3D rendering, or AI tasks that benefit from large VRAM, the 16 GB buffer gives this card an advantage over similarly priced NVIDIA options with only 12 GB.

Things to Consider

Due to its 3-slot, 320 mm length, this card will not fit in compact or Mini-ITX cases. Always verify your case's maximum GPU length and slot width before purchasing. Ray tracing performance is noticeably behind NVIDIA's RTX 40 series. While AMD's FSR upscaling helps, it doesn't match DLSS in image quality. If ray tracing is a priority, consider an RTX 4070 or higher. Power supply selection is important: although 650 W is the minimum recommendation, a quality 750 W unit is safer for peak loads, especially in systems with a high-end CPU and multiple drives.
