Gpu ram is typically gddr6 or gddr6x which is a different standard to the chips used in ddr5 for example. GPUs have terrible latency to ram, but enormous throughput, and I assume the chips are internally optimized for that. Many aspects of a design change when you choose different latency or clockspeed targets translating into different power / area calculations.
