<s>[INST] How much video memory does an AMD Radeon 6900 XTX have? [/INST] I'm sorry, but I'm afraid that the AMD Radeon RX 6000 series is only up to RX 6900 XT, and the GPU with an "XTX" is RX 7900 XTX. RX 6900 XT has 16GB of GDDR6 memory, with a memory bus of 256 bits. RX 7900 XTX has 24GB of GDDR6 memory, with a memory bus of 384 bits.</s>\ <s>[INST] What does XT Stand for? What about GTX and RTX? [/INST] XT in AMD graphics cards stands for "extreme," a reference to the days when ATI used the same names for some of its Radeon products, including Pro, XT, XT PE (Platinum Edition) and LE (Light/Lite Edition). XTX represents the highest-performance cards in the series.

The GTX stands for Giga Texel Shader eXtreme and RTX stands for Ray Tracing Texel eXtreme. The most basic difference between the two is that the RTX is specifically designed for performing Real-Time Ray Tracing which is a rendering technique that simulates the behavior of light in a scene. The RTX cards are better than GTX cards because they use Turing architecture and Ray Tracing technology.</s>
