Estimate GPU memory needs and key milestones by converting between block height, epoch, and DAG size.
Change any field to auto-calculate the others.
Estimated using average block time. Reserve an extra 0.5GB–1GB buffer for mining software and drivers.
Key points for DAG and VRAM planning.
Some PoW algorithms generate a DAG dataset that must be loaded into VRAM; as the DAG grows, older GPUs may be phased out. The DAG is recalculated every epoch (30,000 blocks for most Ethash coins, 60,000 for ETC post-ECIP-1099).
Besides the DAG, mining software and drivers also consume VRAM. Reserve an extra 0.5GB–1GB on top of the DAG size estimate to ensure stable mining operations.
This calculator uses standard Ethash parameters. For highest accuracy, verify your coin's current block height and average block time against a block explorer. DAG sizes are calculated from the official Ethash specification.
