Overall, Nvidia's decision to shelve the RTX 4090 Ti reflects the company's strategic focus on maintaining its market infinite craft leadership while also considering the competitive landscape and the needs of different consumer segments.
Nvidia seems to have internally shelved plans of launching the RTX 4090 Ti with 18,176 CUDA cores, likely because there is no real threat to the RTX 4090's dominance from AMD. Instead, the company could introduce new RTX 4070 and RTX 4060 refreshes. We are also getting to know that the upcoming RTX 50 Blackwell could very well use a 512-bit memory interface.
