Sapphire Pulse RX 7900 XTX 24GB

The Sapphire Pulse Radeon RX 7900 XTX is a graphics card built on AMD RDNA 3 architecture with 24GB of GDDR6 memory across a 384-bit bus. It connects via PCI Express 4.0 x16 and delivers a boost clock of 2525 MHz with 6144 stream processors. The card supports DirectX 12 Ultimate and OpenGL 4.6 for modern gaming and compute workloads.

Ideal for 4K gaming and heavy content creation

This card suits users who need 24GB of video memory for high-resolution textures, large 3D scenes or AI inference workloads. The dual HDMI 2.1 and dual DisplayPort 2.1 outputs drive up to four monitors at high refresh rates. Buyers targeting 1080p or 1440p gaming only, or systems with limited power headroom, should consider a lower-tier model instead.

Standard ATX installation with dual-slot cooler

Installation follows the usual PCI Express 4.0 x16 slot procedure and requires two 8-pin power connectors from the PSU. The dual-slot cooler fits most ATX cases, but verify length clearance before purchase. Common issues include forgetting to connect both power cables or running an outdated motherboard BIOS that limits PCIe 4.0 link speed.

Questions about this item

What power connectors does the PULSE Radeon RX 7900 XTX require from my PSU?

The card draws power through two 8-pin PCIe connectors; your power supply must provide both and deliver enough wattage for a 2525 MHz boost clock.

Will the PCI Express 4.0 x16 interface run at full speed on my older PCIe 3.0 motherboard?

Yes, the card is backward compatible and will operate at PCIe 3.0 x16 speeds on a 3.0 board, though bandwidth is halved compared to a 4.0 platform.

How can I verify the 24 GB GDDR6 memory is running at the rated 20 Gbps effective clock?

Open GPU-Z or AMD Software: Adrenalin Edition and confirm the memory clock reads 20000 MHz on the sensor tab.
