We complain about the Apple tax on Unified Memory, but enterprise HBM costs 10x more ($13-$20+/GB vs $3-$5/GB for standard RAM). The payoff? A massive 10x jump in bandwidth (up to 4.8+ TB/s) by trading a narrow 512-bit bus for an ultra-wide 8192-bit vertical stack. excited for apple to start putting hbm in their laptops Consumer GDDR6/GDDR7 (GPU VRAM): Costs roughly $2 to $3.50 per GB. Standard DDR5 / LPDDR5 (Laptop/Desktop RAM): Costs roughly $3 to $5 per GB. HBM3e / HBM4 (Enterprise Memory): Costs between $13 to $20+ per GB so 10x the cost for 10x the bandwidth. fair trade imo
