GIGABYTE GV-R79XTGAMING OC-20GD Radeon RX 7900 XT graphics card

20GB Radeon RX 7900 XT

This GIGABYTE Gaming card delivers 20GB of GDDR6 memory on a 320-Bit interface with 5376 stream processors. It targets enthusiasts building high-refresh 1440p or entry 4K rigs who need ample frame buffer for heavy textures. The triple-fan cooler handles the 300W TDP within a 3-slot ATX form factor. PCI Express 4.0 x16 provides the host link.

Upgrade from 8-12 GB cards

Moving from 8GB or 12GB models removes VRAM bottlenecks in modern titles and creative workloads at 1440p ultra or 4K high settings. The 20GB buffer and wider bus justify the step up when texture packs, modded scenes or professional viewports exceed smaller capacities. A recommended 800W PSU with two 8-pin connectors is required.

PCI Express 4.0 x16 limits

The card runs at PCI Express 4.0 x16; on a 3.0 platform the link halves to 4.0 x8 equivalent bandwidth, which can marginally affect 1% lows in bandwidth-heavy scenes at 4K. DisplayPort 2.1 and HDMI 2.1 outputs support 7680 x 4320 resolution and four simultaneous displays. The 331 mm length demands a case with adequate clearance.
