Review of the AMD Radeon RX 6600 XT Desktop GPU (8 GB)

The Radeon RX 6600 XT is AMD’s mid-range RDNA 2 graphics card. It is intended primarily for 1080p gamers. The RDNA 2 GPU is quite energy-efficient. We shall touch on performance a bit later in our review.

There is no reference model of the Radeon RX 6600 XT. Unlike with the higher-end 6000-series GPUs, only board-partner models are available. For this review, AMD sent us the XFX Speedster MERC 308 AMD Radeon RX 6600 XT. This is one of the more premium models with a triple-fan cooler. All in all, the cooling system works well, which is not surprising given the TGP of just 160 W. The XFX model of the Radeon RX 6600 XT looks premium, even though the shroud is made of plastic. However, the backplate is made of metal, which is why it makes the 27.4-cm (10.8 ″) graphics card feel very sturdy. The backplate is not involved in cooling any GPU components because it does not have any thermal pads.

The AMD Radeon RX 6600 XT supports all the latest RDNA 2 features. It is worth mentioning, though, that it only has 32 RT cores, which means that it will not be able to keep up with faster RX 6000-series GPUs when it comes to ray-tracing performance. The RX 6600 XT supports SAM (Smart Access memory). This means that the graphics chip can access all 8 GB of VRAM at the same time. The 6600 XT has a 128-bit-wide bus. The Radeon RX 6700 XT, on the other hand, has a 192-bit-wide bus, which is one of the reasons why it is faster. The 6600 XT (2048) also has fewer streaming processors than the 6700 XT (2560). You can see the full specifications in the table below.

Our review model features the bog-standard selection of ports for this kind of GPU (3 DP ports; 1 HDMI port). The graphics card is supplied with power via an 8-pin connector.
