Radeon RX 7900 GRE 16GB Gaming Card

The GIGABYTE GV-R79GREGAMING OC-16GD is a Radeon RX 7900 GRE graphics card with 16GB GDDR6 memory on a 256-bit interface. It targets gamers and creators who want high frame rates at 1440p or entry 4K using the RDNA 3 architecture. The triple-fan cooler handles the 260W thermal design power in a standard ATX form factor.

Check PSU and Case Clearance First

Your power supply must deliver at least 700W and provide two 8-pin PCIe connectors for this card. The board occupies 2.7 slots and measures 302 mm in length, so verify that your case has enough clearance and that the motherboard PCI Express 4.0 x16 slot is free. Ensure the rear bracket area can accommodate two HDMI 2.1 and two DisplayPort 2.1 outputs.

Sustained Load Behaviour

Under continuous gaming or compute workloads the 5120 stream processors and 18 Gbps memory maintain stable clocks while the triple-fan array manages heat within the 260W limit. The 16GB frame buffer prevents texture streaming stalls during long sessions at 7680 x 4320 resolution. Fan curves ramp gradually to balance acoustics and temperature over extended periods.

Questions about this item

What comes in the box with the GV-R79GREGAMING OC-16GD and what must I buy separately?

The card itself includes the triple-fan cooler, 2 x HDMI 2.1 and 2 x DisplayPort 2.1 outputs, and the 2 x 8-pin power connectors attached. You must supply a PCIe 4.0 x16 slot, a 700 W or larger PSU, and any display cables.

How do I choose between the 16 GB and other memory capacities for the RX 7900 GRE?

This model is only offered with 16 GB GDDR6 on a 256-bit bus at 18000 MHz. No other capacity exists for this SKU, so the choice is simply whether 16 GB fits your workload.

What does the 260 W TDP mean once the card is installed in my PC?

The 260 W thermal design power sets the cooling and PSU requirement; pair it with a 700 W unit and a case that fits a 302 mm, 2.7-slot card so the triple-fan cooler can dissipate that heat.
