20GB GDDR6 320-bit graphics card

This Sapphire Radeon RX 7900 XT delivers 20GB of GDDR6 memory across a 320-bit interface with a 2400 MHz boost clock. It targets enthusiasts building high-resolution gaming systems or workstations needing large frame buffers. The triple-fan cooler handles the 300W thermal design within a 276 mm, three-slot form factor.

Upgrade from 12GB cards

Moving to 20GB removes the texture-streaming ceiling that appears at 4K and ultra settings on 12GB models. The 5376 stream processors and 2000 MHz game clock lift minimum frame rates in memory-heavy titles. A 750W power supply and two 8-pin connectors are required for stable operation.

Suits 4K and multi-monitor users

Four-display support via one HDMI 2.1, two DisplayPort 2.1 and one USB Type-C drives 7680 x 4320 workflows. Buyers needing single-slot or low-profile designs, or systems limited to PCI Express 3.0 bandwidth, should look at smaller cards.

Questions about this item

Will the 276 mm length and 3-slot width fit my case and motherboard spacing?

The card measures 276 mm long and occupies 3 expansion slots, so verify your case clearance and that two adjacent rear brackets are free.

What power connectors are required and which step do builders often miss?

Two 8-pin PCIe connectors are needed from a 750W supply; the common mistake is using a single daisy-chained cable instead of two separate runs.

How should I maintain the triple-fan cooler over time?

Periodically remove dust from the three fans and heatsink fins with compressed air to keep the 300W thermal design within limits.
