New Intel next-gen GPU Battlemage rumour pegs it as an RTX 4070 Super competitor with 16 GB VRAM and launching next month

Hi, guys. I saw the news about the Intel Arc battlemage cards and they seem to be great. But the last gen Intel GPU were also claimed to be amazing and ended up a total disappointment.
Do you guys think this gen will be better than last gen or will it be the same?
Also I would love to hear about the Alchemist gpu’s from someone who bought it. How was the initial experience and how much has it improved?
Are Intel Gpus worth investing in?
