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.
The model in question is a forthcoming GeForce RTX 4070 Ti Super Ventus 3X Black OC (err, are you sure you couldn't make that name any longer, MSI?) and it was noticed by X-user wxnod (via BenchLife). If you're wondering how we know it's using a cut-down RTX 4090 chip, there are two clues.
