M1Pro and max runs games on DDR5 so it's an APU not a dGPU that use GDDR6. Even M2 will use LPDDR%X @8400MT7s with lowest latency will never compete against 8GB GDDR6 @18Gbps.
You're actually on the wrong track here. DDR memory has significantly lower latency compared to GDDR, which is why it's used for CPU memory on PCs. But bandwidth wise, DDR is much slower than GDDR, which is why GDDR is used as video memory.
I don't know if Apple uses LPDDR or GDDR for their unified memory architecture, but if its DDR then that's absolutely genius.
Because the apple memory is crazy fast bandwidth wise, just like GDDR6 (400 GB/s) but also has extremly low latencies as it's still DDR. You can say they combined the best of both worlds into the ultimate memory, and that's just crazy. Both the CPU and GPU part of the SoC can be fully satisfied that way, unlike a regular APU with just either GDDR (consoles) or DDR (low end APUs).
