Nope it doesn't that is 12 channels 2 modules per channel each module at 2GB is the largest the chip gets and the cost of those drastically increase the cost.

The problem you experience with GDDR6 and channels is width. You get higher in size but you'll never be able to fill the memory fast enough to be cost effective. Also why HBM exists. Lets say the top is 960GB/s for an A6000 for GPU memory. HBM3 is 3.35 TB/s.

If Intel wanted to make better GPUs it needs to switch to HBM.
