MSI is using cut-down RTX 4090 GPUs in at least one of its RTX 4070 Ti Super models, with a higher TGP but no extra performance
Chip manufacturing isn't perfect and every wafer a foundry churns out will have dies in it that can't be used for their originally intended purpose. That doesn't mean they can't be used at all, though, and in the case of Nvidia's hulking AD102 GPU, normally used in RTX 4090 graphics cards, MSI is buying defective ones and using them in at least one of its GeForce RTX 4070 Ti Super models.
