Introduction
The AMD Radeon RX 6600 XT was announced on July 29th at Chinajoy 2021, and the official press introduction and early reviews were published on August 10th, 2021. We have a full introduction of the Radeon RX 6600 XT, and what it is all about published. Please check out that introduction for all the specifications and information.
The AMD Radeon RX 6600 XT was launched with an official MSRP of $379. On August 11th, we published our first add-in-board partner video card review. The AMD Radeon RX 6600 XT is an AIB card, so that makes sense. Today we have another add-in-board video card review of it for you. This is the MSI Radeon RX 6600 XT GAMING X 8G video card, which represents the best-of-the-best from MSI based on the Radeon RX 6600 XT.
The AMD Radeon RX 6600 XT is based on the NAVI 23 die on the AMD RDNA2 architecture. It has 2,048 stream processors, 64 ROPs, 128 TMUs, and 32 RT Cores. It has 32MB of Infinity Cache. The game clock is set at 2359MHz and the boost clock at 2589MHz. It has 8GB of GDDR6 on a 128-bit bus at 16GHz, providing 256GB/s of memory bandwidth. The TDP is 160W.
MSI Radeon RX 6600 XT GAMING X Specs
In the US market, under Radeon RX 6600 XT GPUs on MSI’s website, you’ll find two distinct models, the MECH 2X and the GAMING models. The MECH 2X model has an OC and non-OC model, and the GAMING has the X and non-X models. The GAMING series feature MSI’s TWIN FROZR 8 thermal design and TORX FAN 4.0 and Mystic Light RGB. The MECH series has MSI TORX FAN 3.0 and is a performance-focused essential design for play or for work. We have the GAMING X model, which has the best and robust configuration for gaming, with the highest factory overclock.
The MSI Radeon RX 6600 XT GAMING X 8G video card has a factory overclock setting the gaming clock at 2428MHz and the boost clock at 2607MHz. This is compared to the reference spec being 2359MHz game clock and 2589MHz boost clock. That’s a 69MHz overclock or 3%.
The thermal design configuration on the MSI Radeon RX 6600 XT GAMING X is MSI’s TWIN FROZR 8. A big part of that is also the TORX FAN 4.0 which pairs fan blades together with an outer ring design that focuses on airflow into the cooling system. They also support Zero FROZR which keeps the fans off and silent at low load levels. It also uses MSI’s Core Pipes which are precision-machined heat pipes that have full contact with the GPU and spread heat along the full length of the heatsink. The heatsink has Airflow Control that has deflectors on the surface area that guide air to where it is needed for cooling. Additionally, it uses Wave-curved 2.0 fin edges to disrupt unwanted airflow harmonics resulting in reduced noise.
There is also a sturdy aluminum Metal Backplate that is a matte-finish backplate that both reinforces the graphics card and also provides passive cooling with thermal pads. It runs the full length of the video card. There is also an anti-bending metal strap built into the video card to make the video card more rigid and less prone to bending. There are additional fuses built into the custom PCB that provide additional layers of protection against electrical damage. The PCB material is designed with 2oz of thickened copper to increase conductivity and improve heat dissipation and reliability. The video card features MSI Mystic Light RGB that can be controlled in software with MSI Center.
The video card has three DisplayPort v1.4 and one HDMI 2.1 port. It requires one 8-pin PCI-Express power connector. The recommended PSU is 500W or greater. The video card measures 10.9 inches long, 5.1 inches in width, and 2 inches in height, it is a 2-slot design.
