That's because, according to the super secret AMD Decoder Wheel, the 7 series just means it came out in 2023, while the 8 series means it comes out in 2024, and the 9 series is any model released first released in 2025. Which means you can't use the first digit to tell what architecture the CPU is at all, you need the 2nd digit and 3rd digit. Which means this "leak" about 9000 series is not a leak because AMD has already stated, for over a year now, that the 9 series would be CPUs released in 2025.
