AdoredTV picked up rumors that Intel is tapping TSMC to produce its Xe "DG2" GPU. The exact reason here is unknown. Intel previously promised that its 7nm Xe "DG1" GPU would be one of the first products that will use its own 7nm node so it's unknown why the chip giant plans to use TSMC for the DG2, which is scheduled for 2022. The performance of DG2 is believed to be "mid-range or lower".
Obviously, why Intel would do such a thing is an important question. Well, there could be concerns at Intel about their 7nm capacity (even if their 7nm node is great), or maybe it’s an issue with cost since new nodes are more expensive than old ones, and gaming GPUs do need to be cheap. This might also have to do with Intel’s hiring spree of former AMD and Radeon employees; perhaps Intel went after these veterans due to their familiarity with TSMC processes.
