Sapphire PURE Radeon RX 7800 XT 16GB

The Sapphire PURE Radeon RX 7800 XT 16GB is a graphics card built on a 5nm GPU using AMD RDNA 3 architecture. It delivers 3840 stream processors across 60 compute units with 64MB Infinity Cache and 60 ray accelerators. The 16GB GDDR6 frame buffer runs on a 256-bit bus at 19.5 Gbps effective speed.

Gamers targeting high-refresh 1440p or entry 4K

This card suits players who want strong raster performance at 1440p high refresh rates or playable 4K in modern titles. The 16GB buffer helps with texture-heavy games and some creative workloads. Buyers who need more video memory for professional 4K or 8K editing pipelines, or who require a smaller form factor for compact chassis, should consider other options.

Dual HDMI and dual DisplayPort 2.1a outputs

The board provides two HDMI and two DisplayPort 2.1a connectors, each capable of 7680×4320 resolution, enabling up to four simultaneous displays. A high-TG copper PCB and digital power design support stable operation at the rated 2475 MHz boost and 2169 MHz gaming clocks. The 2.5-slot, 320mm length fits standard ATX cases without additional brackets or adapters.

Questions about this item

Does this RX 7800 XT need a specific power-supply connector?

The card plugs into a PCIe 4.0 x16 slot and draws power through standard PCIe connectors; check the card's own connector layout when it arrives.

Will the 320 mm length and 2.5-slot thickness fit alongside my existing ATX motherboard and CPU cooler?

The board measures 320 mm long, 128.75 mm wide and 52.57 mm tall, so verify case clearance and motherboard slot spacing before installing.

How can I confirm the GPU is hitting its 2475 MHz acceleration clock and 19.5 Gbps memory speed after setup?

Run a GPU monitoring tool and watch for core clocks up to 2475 MHz and an effective memory rate of 19.5 Gbps under load.
