Radeon RX 7900 GRE for 1440p gaming

The XFX Gaming Radeon RX 7900 GRE is a 16GB graphics card built on AMD RDNA 3 architecture. It targets gamers who want high frame rates at 1440p and credible 4K performance in modern titles. The card delivers 5120 stream processors with a boost clock of 2395 MHz and 256-bit GDDR6 memory.

Check PCIe slot power and case length

Your motherboard must provide a PCI Express 4.0 x16 slot and the case must clear a card length of 335 mm. The power supply should meet the 700 W recommendation to handle the 245 W board power. Verify that two 8-pin PCIe power connectors are available from the PSU.

Triple-fan cooler occupies 2.5 slots

The triple-fan thermal solution occupies 2.5 expansion slots, so ensure adjacent slots are free for airflow. Display outputs comprise one HDMI 2.1 and three DisplayPort 1.4 ports for up to four monitors at 7680 x 4320 resolution. The card supports DirectX 12 Ultimate and OpenGL 4.6 for current APIs.

Questions about this item

What cables or adapters are included with the XFX RX-79GMERCB9, and what must I source separately?

The card provides one HDMI 2.1 port and three DisplayPort 1.4 outputs; any monitor cables or power adapters are not included and must be purchased separately.

How do I decide between the 16 GB GDDR6 version and other capacities for the RX 7900 GRE?

This model ships with 16 GB of GDDR6 on a 256-bit bus; no other memory capacity is offered for this SKU.

What does the 2395 MHz boost clock mean for actual frame rates in games?

The 2395 MHz boost clock is the peak frequency the GPU can reach under load; sustained game clocks sit at 2052 MHz, so real-world frame rates will reflect the lower sustained speed rather than the peak figure.
