Notes
- Plot times depend on specific hardware and compression level (the higher the compression the shorter the plot time)
- Chiapos: most dependent on SSD sustained write speed
- madMAx, Bladebit ramplot/diskplot, Gigahorse CPU: most dependent on CPU and SSD sustained write speed
- Bladebit CUDA, Gigahorse CUDA: most dependent on PCIe generation and GPU (e.g. PCIe3 is maxed out with a 3060ti)
- Gigahorse CUDA 1/2 and 1/4 partial RAM: most dependent on RAM speed and SSD(s) sustained write speed. 1/4 partial RAM can have SSD load split across two devices.
- Higher compression (smaller plot files) also require additional consideration for farming/harvesting workload
- madMAx and gigahorse CPU plotter scales with more CPU threads
- Supported Nvidia GPUs: GTX 1000/1600 series, RTX 2000/3000/4000 series
- Gigahorse GPU plotter supports cards with only 4GB of VRAM but 8GB is recommended
- GPU plotters will require a fast SSD buffer drive to write plots to (they generate plots faster than a single HDD can write)
- Chiapos is slow but is well suited for plotting directly to HDDs, especially in parallel due to low CPU and RAM requirements
- Farming Gigahorse compressed plots is only compatible with the Gigahorse farmer and has an additional dev fee
Larger K-sizes
- As a rule of thumb, K33 will have double the RAM and SSD requirements as K32.
- There are no foreseeable plans to move to K33 minimum plot size.
- Most plotters support K32, K33, K34
- Currently, Bladebit GPU does not support K33+
Expected future developments
- AMD GPU support
- Larger k-size support across all plotters
- Bladebit CUDA integration into Chia GUI
- Bladebit CUDA (partial RAM) RAM requirement reduced to 128GB
- Gigahorse CUDA (partial RAM) RAM requirement reduced to 64GB
- Harvesting support for compressed plots (no GPU needed on harvesters)
- Bladebit ramplot RAM requirement reduced to 256GB
