Powerful Hardware

Stronger Moves

Chess engines work by searching ahead as many moves "deep" as the think time allows. NCM's Ryzen 7950X 16 CPU-core and RTX 2080 GPU servers accelerate this search to produce stronger moves.

Faster Moves

Our dedicated hardware can give you stronger moves in shorter time. For example, Stockfish 15 running for 1 second per move on 16 CPU cores is significantly stronger than Stockfish 15 running for 5 seconds per move on a single CPU core.

Reliable Performance

With NCM Pro, each time you hit calculate, NCM finds an idle server to perform your calculation and your calculation only. The engine can then use every bit of the server's processing power.

Frequently Asked Questions

What difference do the 16 CPU core servers make?

Quite a bit. The faster hardware allows the engine to evaluate more positions per second and get "deeper" (see more moves ahead) than the single core hardware. Thus the engines are able to find stronger moves at depths that the single core hardware can't reach.

For example, we had Stockfish 15 play 1,000 games against itself, one side on the single-core hardware and the other on the 16-CPU core hardware, each at 5 seconds per move. Stockfish running the 16-CPU core hardware won 293 games, drew 702, and lost 5.

Why are calculations limited to 30 seconds?

To maintain server availability, we restrict each calculation to a maximum of 30 seconds. This time limit helps to minimize queuing and ensure that there's always an idle server available to handle your calculation.
