  • HDMI 2.1 and DisplayPort 2.1 outputs drive up to four 8K displays
  • PCI Express 4.0 x16 interface provides maximum bandwidth for modern motherboards

Sapphire Tech PULSE Radeon RX 7900 XTX 24GB

This graphics card targets enthusiasts and creators who need high frame rates at 4K resolution and ample memory for demanding workloads. It is built on the RDNA 3 architecture and uses a 5 nm GPU with 96 compute units. The board delivers 6144 stream processors and a 384-bit memory interface. It fits a standard ATX form factor and connects via PCI Express 4.0 x16.

24 GB GDDR6 capacity with 384-bit bus

The 24 GB GDDR6 frame buffer runs at 20 Gbps effective across a 384-bit bus, providing substantial bandwidth for 4K gaming and large texture sets. The 96 MB Infinity Cache adds extra headroom for bandwidth-sensitive titles. In memory-heavy scenarios such as high-resolution texture packs or compute tasks, the 24 GB capacity reduces the risk of swapping to system RAM. The 330 W typical board power indicates the thermal budget required to sustain these clocks.

Dual BIOS and triple-fan cooling

A dual-BIOS switch lets users choose between a performance profile and a quieter profile without software. The triple-fan cooler uses a large heatsink to manage the 330 W typical board power under sustained load. In the quieter BIOS setting, fan speeds stay lower during typical gaming sessions while temperatures remain controlled. The card draws power through three 8-pin connectors and requires adequate case airflow.

Questions about this item

Will this card run in a motherboard that only has a PCIe 3.0 x16 slot?

Yes. The card uses a PCI Express 4.0 x16 interface and is backward compatible with PCIe 3.0 slots, though bandwidth will be limited to the older standard.

How can I verify the GPU is hitting its 2680 MHz boost clock during a game?

Use monitoring software to watch the core frequency under load; it should reach up to 2680 MHz when thermal and power headroom allow.

Does the box include any power adapters for the 12VHPWR connector, or do I need to buy them?

The card requires two 8-pin PCIe power cables from your PSU; no adapter is included, so purchase one if your power supply lacks native connectors.
