It depends, as Professional GPUs always tend to have at least double the VRAM of their consumer counterparts, so I doubt this will be Intel's RTX4090 equivalent.
For example, the RTX4090 has 24GB of GDDR6X VRAM, whereas its Professional counterpart, the RTX6000 Ada Generation has 48GB of GDDR6 VRAM with ECC.
A new leak says Intel could launch an enterprised-focused Battlemage GPU in 2024. It will feature 24 GB of VRAM and will likely launch under the Arc Pro lineup for data centre and AI applications.
