Sapphire Pulse RX 7800 XT 16GB

The Sapphire Pulse Radeon RX 7800 XT is a graphics card built on AMD RDNA 3 architecture with a 5 nm GPU. It carries 3840 stream processors across 60 compute units with ray and AI accelerators. The 16 GB GDDR6 frame buffer runs on a 256-bit bus. It targets gamers and creators who want high frame rates at 1440p and 4K.

Upgrade from 12 GB cards or older RDNA 2 models

Moving from a 12 GB board or an RDNA 2 generation card adds 4 GB more video memory and the 64 MB Infinity Cache of RDNA 3. The jump is worth it when texture-heavy titles exceed 12 GB or when ray-tracing workloads benefit from the dedicated ray accelerators. The PCIe 4.0 x16 interface and dual HDMI plus dual DisplayPort 2.1 outputs carry over unchanged.

PCIe 4.0 x16 and DisplayPort 2.1 limits

The card plugs into a PCIe 4.0 x16 slot; bandwidth halves if the platform only supports PCIe 3.0. DisplayPort 2.1 can drive 7680×4320 resolution, but the link speed depends on cable quality and monitor implementation. HDMI also reaches 7680×4320 yet is capped by the HDMI 2.1 specification the port follows. The 2.5-slot cooler fits standard ATX cases measuring 280 mm long.

商品問答

Will the 2.5-slot card fit in my ATX case?

The card measures 280 mm long, 128.75 mm wide and 52.57 mm high, so check your case clearance against those dimensions.

What power connectors are required for the Digital Power Design?

The board uses Sapphire's Digital Power Design with ultra-high performance conductive polymer aluminum capacitors and fuse protection; refer to the card's connector layout for the exact PCIe power plugs needed.

Can I run four 7680×4320 displays at once?

The RX 7800 XT supports up to four displays with HDMI and DisplayPort 2.1 outputs, each capable of 7680×4320 resolution.
