"said their graphic card in M1 MAX has the same performance as mobile 3080 using much less power" Apple never said it compared to a 3080 in Gaming Performance. People made conjectures that it could be roughly in that arena. In Productivity applications (work applications that use a GPU), there it's very close to a 3080. Also, TFLOPS is a terrible number for performance because it depends on the level of precision and is highly variable on workload. Good luck loading, say, a 48GB 3D Model on a RTX 3090 - but a M1 Max would handle it fine. Similarly, the 10.8 TLOPs PlayStation 5 had better performance than the 12 TFLOPs Xbox Series X for months after launch. Finally, as for many of the games that were compared - notice how many of them use MoltenVK, which is a Vulkan -> Metal translator that impacts performance. Then look at how many were x86, needing Rosetta translation on top of that. These weren't exactly the most native of game ports.
