8GB RDNA 2 graphics card for 1080p gaming

This MSI Radeon RX 6600 XT Mech 2X 8G OC delivers 8GB of GDDR6 memory on a 128-bit bus with a boost clock of 2602 MHz and 2048 stream processors. It targets 1080p gaming at high refresh rates and supports DirectX 12 Ultimate with OpenGL 4.6. The dual-fan thermal design uses TORX Fan 3.0 to manage the 160W board power. It fits a standard dual-slot bracket and occupies two expansion slots.

PCIe 4.0 slot and 500W PSU with one 8-pin connector

Verify that your motherboard provides a PCI Express 4.0 x16 slot for full bandwidth, though the card also works in PCIe 3.0 slots at reduced speed. A power supply of at least 500W with a single 8-pin PCIe connector is required to meet the 160W TDP. Ensure your case has enough length clearance for a dual-slot card and that rear I/O brackets align with one HDMI 2.1 and three DisplayPort 1.4 outputs. The board draws all auxiliary power from the 8-pin connector.

Dual-fan cooler and four-display output array

The TORX Fan 3.0 cooler pushes air through a compact heatsink to keep temperatures in check during extended sessions. One HDMI 2.1 port supports 4K at 120Hz or 8K at 60Hz with VRR, while three DisplayPort 1.4 connectors enable up to four simultaneous displays at a maximum resolution of 7680 x 4320. The metal backplate adds rigidity and protects the PCB from flex during installation or transport. All outputs are HDCP ready for protected content playback.

Questions about this item

What comes in the box and do I need to buy any cables or power adapters separately?

The card includes the dual-fan GPU with one 8-pin power connector, one HDMI 2.1 port and three DisplayPort 1.4 outputs. Cables for those ports and a PSU with an 8-pin lead are not included.

There is only one capacity listed — how do I know this 8 GB model is the right choice?

This SKU ships with 8 GB of GDDR6 on a 128-bit bus at 16 Gbps. No other memory size or bus width exists for this model, so the listed configuration is the only option.

What does the 2602 MHz boost clock actually deliver in a real system?

The 2602 MHz boost clock is the peak frequency the RDNA 2 GPU can reach under load, paired with a 2413 MHz game clock and 2048 stream processors, drawing up to 160 W from a recommended 500 W supply.
