16GB 256-Bit GDDR6 graphics card

The PowerColor Hellhound Radeon RX 7900 GRE delivers 16GB of GDDR6 memory across a 256-Bit interface. It targets gamers and creators who need high frame rates at 1440p or entry 4K. The PCI Express 4.0 board occupies 2.5 slots and measures 332 mm in length. Two 8-Pin power connectors feed the 250W thermal design power.

Sustained load behaviour

At the 2013 MHz game clock the 5120 stream processors maintain steady throughput in extended sessions. The 2366 MHz boost clock lifts performance during peak demands without prolonged overclocking. A 750W power supply is recommended to keep voltage rails stable under continuous draw. Driver support for DirectX 12 and OpenGL 4.6 ensures compatibility with current titles.

Thermals noise and power

The triple fan cooler moves air across a full length heatsink to manage the 250W TDP in typical chassis airflow. Fan curves stay moderate at idle and rise gradually as temperature climbs. Power draw tracks close to the rated figure during gaming loads. The card supports up to four displays via one HDMI 2.1 and three DisplayPort 2.1 outputs at 7680 x 4320 maximum resolution.

Questions about this item

How loud and hot does the triple-fan cooler run when the 250W TDP card is pushed all day?

The triple-fan design targets the 250W thermal design power; expect fan noise to rise under sustained load and case airflow to determine peak temperatures.

What power supply and connectors must my system already have for this 250W card?

A 750W PSU with two 8-pin PCIe power cables is required to feed the card.

Will the 332 mm, 2.5-slot board fit alongside my existing PCIe 4.0 motherboard and older monitors?

The card uses a PCI Express 4.0 x16 slot, measures 332 mm long and occupies 2.5 slots; it also provides one HDMI 2.1 and three DisplayPort 2.1 outputs for legacy displays.
