For this test, AMD has supplied us with a customized model made by MSI, and reference cards from AMD are not available at the present moment. It is, in fact, it’s the MSI Radeon RX 6600 XT Gaming X 8G, which comes with its custom PCB and cooling system. The 277 x 130 x 50-millimeter card isn’t enormous, but it can use an 8-pin connector and two fans. This is what we know by MSI under the name Twin Frozr 8, where two fins of each fan are connected inside each card. This highly efficient system keeps the card at a temperature of 65°F at all times, even with a full load. Excellent.
Inside the card, the Navi-23 chip is working using just 248 shaders. This is not uncommon for AMD, which typically has a small number of shaders, but with a fast clock speed. This is the same with the AMD RX 6600 XT that runs on 2,428 Mhz in regular mode. However, it is listed as 2,607 MHz when running Boost. In actual use, the speed could even go up and reach 2,660MHz.
However, it appears smaller when it comes to memory. With 8GB of GDDR6, the card seems inferior to the Direct competition, which comes with 12 GB of RAM. Memory interfaces are not as impressive, with just 128 bits. The Infinity Cache is also tight with 32 megabytes. But, it is adequate for the Full HD resolution. Less memory is the primary reason that this card is too costly in a straight comparison. However, its power efficiency is quite good. As per the specifications of the maker, its TDP is 160W. However, according to GPU-Z, they found it to be less expensive in actual use and was clocked to the maximum, just 148W.
The initial assumptions concerning its performance which are focused on 1080p resolutions, are later confirmed in benchmarks. This RX 6600 XT typically is positioned between the rival cards RTX 3060 and RTX 3060 Ti. Games played in Full HD are no problem, even at the highest settings. The goal of 60 frames per second is not at risk.
At 1440p, the initial problems appear when you cut back the graphic settings. The card is ideally suited for this. Thirty fps is always achievable, but for the 6ss fps, it isn’t often enough. To ensure completeness, to be more precise, for resolutions of 4K such as it is recommended that the RX 6600 XT isn’t an option. Those who wish to make it somewhat more up-to-date under 1440p should consider an RX 6600 XT or one of their larger versions.
The primary weak point in the AMD card is that it does not support the ray tracer. Even at 1080p resolution, it is not able to provide good results. In the case of Watch Dogs Legion, the game was not playable on the three ray tracer settings in Full HD.
This would be the third reason that AMD’s AMD card is overpriced compared to RTX 3060 (Ti). Considering that NVIDIA retains the DLSS bonus in its account, AMD’s alternatives can’t stand an equal position. But, those who skip ray tracing receive a robust and powerful graphics card that can run Full HD.
