Introduction to the AMD Radeon RX 6600 XT. Review and testing of the video card ASUS ROG-STRIX-RX6600XT-O8G-GAMING


It’s time to get acquainted with another novelty AMD. Recently, the new Radeon RX 6600 XT graphics card was introduced, which is the most affordable solution based on the RDNA2 architecture. Let’s talk about its features and benefits. Consider the model of the ASUS ROG Strix line and compare it with the GeForce RTX 3060.

AMD is positioning the Radeon RX 6600 XT as a Full HD gaming solution. This resolution is still the main one, and two-thirds of gamers use 1920×1080 monitors. At the same time, the potential of the video card is quite high, and if you do not chase indicators above 100 fps, the video card allows you to play some games at 1440p.

The novelty is based on the new Navi 23 processor with 32 Compute Units, which operate on 2048 streaming cores with 128 texture units and 64 ROPs. Navi 23 also has 32 dedicated Ray Accelerator blocks to speed up ray tracing operations. A large 32 MB Infinity Cache L3 cache has been implemented. Set high operating frequencies Game Clock 2359 MHz and Boost Clock 2589 MHz. The memory bus is 128 bits, 8 GB of GDDR6 memory with a frequency of 16000 MHz is used.

The next in the hierarchy, the AMD Radeon RX 6700 XT model operates with 2560 stream processors and 40 Ray Accelerator cores with a 192-bit bus and 96 MB Infinity Cache. Compared with the old generation, the characteristics of the Radeon RX 6600 XT look more modest than the parameters of the Radeon RX 5600 XT, which had more computing units and a 192-bit bus. In reality, the new architecture and high frequencies provide higher performance than the Radeon RX 5700. The narrow bus is compensated by a redesigned memory subsystem with a large cache. And on board the Radeon RX 6600 XT is two gigabytes more than the Radeon RX 5600 XT.

An important advantage of the novelty is the low power consumption of 160 watts. At the same time, the Radeon RX 6600 XT is positioned as a solution that surpasses the GeForce RTX 3060 with a power of 170 watts.

The Radeon RX 6600 XT fully supports DirectX 12 Ultimate, including ray tracing, Variable Rate Shading and more. AMD FidelityFX Super Resolution scaling technology delivers massive performance gains in heavy-duty applications, especially important for tracing games. There is support for AMD Smart Access Memory technology, which will provide additional acceleration on compatible boards.

The video card supports the fast PCI Express 4.0 bus, but uses eight lanes. And if you didn’t have time to upgrade to a new AMD or Intel platform, the PCI Express 3.0 bus can slightly limit the potential of the video card in some games. Previously, the Radeon RX 5500 XT was released with a stripped-down interface.

AMD partners have introduced a variety of graphics cards with different cooling. Most models are equipped with a dual-fan cooler, but there are versions with three fans, like older video cards.
