Dual Radeon RX 6600 for 1080p gaming

The ASUS DUAL-RX6600-8G is a refurbished graphics card built around the AMD Radeon RX 6600 GPU. It delivers 1792 stream processors and 8GB of GDDR6 memory across a 128-bit interface. The card targets gamers running 1080p displays who want modern API support including DirectX 12 Ultimate and OpenGL 4.6. A dual-fan cooler handles the 132W thermal design power within a 2.5-slot form factor.

Sustained load behaviour at 132W TDP

Under continuous load the GPU operates at a game clock of up to 2044 MHz in standard gaming mode or 2064 MHz in OC mode, well below the 2491 MHz boost figure. The 132W power limit and dual-fan thermal solution keep clocks stable during extended sessions without relying on short burst frequencies. An 8-pin power connector feeds the board while a 500W power supply is recommended for the full system. The 243 mm length fits most mid-tower cases.

PCI Express 4.0 and display output limits

The card connects through a PCI Express 4.0 x8 interface, providing sufficient bandwidth for the 128-bit memory subsystem at 1080p resolutions. Video output uses one HDMI 2.1 port and three DisplayPort 1.4a connectors, driving up to four monitors at a maximum digital resolution of 7680 x 4320. This port arrangement suits multi-display productivity setups as well as high-refresh gaming panels.

Questions about this item

How loud and hot does the DUAL-RX6600-8G get when it runs all day at its 132W TDP?

The card draws up to 132W and uses a double-fan cooler in a 2.5-slot design to move that heat out of the case.

What power supply and connector must I already have for this Radeon RX 6600?

A 500W PSU with one free 8-pin PCIe power cable is required.

Will the PCI Express 4.0 interface slow down if I install it in my older PCIe 3.0 motherboard slot?

The card works in a PCIe 3.0 slot at 3.0 speeds; the 4.0 capability is backward compatible.
