Chess engines work by searching ahead as many moves "deep" as the think time allows. NCM's Ryzen 5950X 16-CPU core and RTX 2080 GPU servers accelerate this search to produce stronger 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.
NCM routes each Ryzen 5950X and RTX-2080 GPU calculation to its own exclusive physical server. Your calculations always have 100% usage of the server's computing resources, guaranteeing strong and reliable performance.
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.
