This article covers SAPPHIRE PULSE RX 7800 XT 16GB GDDR6 2ファン.

Overview

The SAPPHIRE PULSE RX 7800 XT 16GB GDDR6 2-Fan is a mid-high range graphics card built on AMD's RDNA 3 architecture. It features the AMD Radeon RX 7800 XT GPU with 16GB of GDDR6 memory over a 256-bit interface, delivering 624.1 GB/s of bandwidth. With a boost clock of 2,430 MHz and a game clock of 2,124 MHz, the card is well-suited for smooth 1440p gaming and can handle entry-level 4K experiences. Its 2-fan design keeps the card length to just 280mm, making it compatible with MicroATX and Mini-ITX builds where space is at a premium. The card comes with a 2-year warranty through official Japanese distributors and requires a PCIe 4.0 x16 slot, dual 8-pin PCIe power connectors, and a recommended 700W power supply. The built-in AV1 encoder is optimized for OBS, providing high-quality streaming at lower bitrates.

Compatibility Guide

This graphics card uses a PCIe 4.0 x16 interface and is backward compatible with PCIe 3.0 slots. It measures 280mm in length and occupies 2.5 slots (approximately 52.6mm thick), so you must verify your case's maximum GPU clearance. The card requires two 8-pin PCIe power connectors; ensure your power supply has at least 700W capacity with the necessary cables. 16GB or more of system RAM is recommended, though 8GB is the minimum supported.

Product Info

Launched in August 2023, the SAPPHIRE PULSE RX 7800 XT is priced around ¥83,333 ( Japan) and comes with a 2-year warranty in Japan. It utilizes the RDNA 3 architecture on a 5nm process node, featuring 3,840 stream processors, 60 ray tracing accelerators, and 120 AI accelerators. The card delivers 18.66 TFLOPS of FP32 performance with a TDP of 263W. The compact 2-fan cooler is a key highlight, allowing it to fit into many small-form-factor cases.

Best Use Cases

This card excels at 1440p high-refresh-rate gaming, offering excellent performance in demanding titles like Cyberpunk 2077 and Call of Duty: Modern Warfare II at high settings. The AV1 encoder makes it an ideal choice for streamers and content creators who use OBS or similar software. Its compact size also makes it perfect for builders aiming to construct a powerful yet space-efficient gaming rig using MicroATX or Mini-ITX cases.

Things to Consider

While the card supports ray tracing, its performance in ray-traced titles is typically lower than that of NVIDIA's GeForce RTX 4070. For creative professionals relying on CUDA-accelerated applications like Adobe Premiere Pro, an NVIDIA card may offer better performance. Additionally, the 280mm length may still be too long for some ultra-compact Mini-ITX cases, so always double-check your case's GPU clearance before purchasing. The 16GB VRAM is generous but may be overkill for pure 1080p gaming.
