MSI’s Gaming Trio cooler concept is not new, as is evidenced by the addition of ‘Classic’ to the title of this AMD Radeon RX 7900 XTX-based graphics card. It is a triple-slot and triple-fan solution, which is a necessity for dealing with the flagship RX 7900 XTX chip. It also comes with RGB highlights and a backplate for added stability.

The MSI Radeon RX 7900 XTX Gaming Trio Classic uses the same GPU and memory clocks as the reference model but differs in some key areas. First and foremost, like the pricier Sapphire Nitro+ card, it comes with an extra 8-pin PCIe power connector for a total of three instead of the usual two.
This will theoretically allow the card to draw additional power from the PSU, enabling additional overclocking and improved performance at the cost of a higher power draw. As always, overclocking results can and do vary from one individual GPU to the next, as non-binned varieties are only tested and guaranteed to run at the specified clocks.
Cooling Solution
Nevertheless, some further overclocking headroom should theoretically be provided by the larger physical dimensions of the MSI RX 7900 XTX Gaming Trio. It is significantly wider than the reference model, allowing more space for heatsinks and fans.
MSI emphasizes the Tri Frozr 2 cooling system with version 4.0 of its Torx fans, which allegedly improves airflow compared to standard fans. Like most modern graphics cards, the RX 7900 XTX Gaming Trio also offers ‘fan stop’ functionality to keep the card entirely silent when idle. Other highlights include thermal padding for the GDDR6 memory chips.
The ‘Mystic Light’ RGB details on the Gaming Trio cooler can be controlled via the proprietary MSI Center app.
About the AMD Radeon RX 7900 XTX
The AMD Radeon RX 7900 XTX is a flagship-class GPU released in late 2022. It uses the Navi 31 XTX variant of the chip, built on a combination of 5 nm and 6 nm process nodes at TSMC. AMD’s Radeon RX 7900 series is the first gaming GPU lineup to be built with a so-called chiplet-based design.
Compatibility with the latest games is ensured via DirectX 12 Ultimate support and the feature set also includes hardware-based raytracing, as well as variable-rate shading. Being a flagship GPU, the Navi 31 is a large chip: the die area is 529 mm² and it contains 57.7 million transistors.
The RX 7900 XTX features 192 ROPs (render output units), 6144 shading units, 384 TMUs (texture mapping units), and 96 raytracing acceleration cores. It is connected to 24 GB of GDDR6 memory via a 384-bit memory bus operating at an effective 20 Gbps.
Performance
Compared to the Nvidia competitors from the RTX 4000 series, graphics cards based on the RX 7900 XTX GPU are consistently slower than the RTX 4090, but often ahead of the RTX 4080 in terms of raw rasterization performance.
When ray tracing is activated, the RTX 4080 is instead faster than the RTX 7900 XTX on average, with the latter sometimes performing on par with Nvidia’s flagship cards from the previous generation.
Note that the above benchmark scores are not specific to the MSI Radeon RX 7900 XTX Gaming Trio Classic but rather average scores for RX 7900 XTX cards from different manufacturers.
