Rand2: evaluation from an array of random Hand objects. Rand1: evaluation from a pregenerated array of random hands (7 x uint8). Results are in millions of evaluations per second. Benchmarks were done on Intel 3770k using a single thread. On 圆4 the impact is small, but in 32-bit mode SSE2 is required for decent performance.īelow is a performance comparison with three other hand evaluators ( SKPokerEval, 2+2 Evaluator and ACE Evaluator). Can be compiled for both 32- and 64-bit platforms but has better performance on 64bit.Has relatively low memory usage (200kB lookup tables) and initialization time (~10ms).The quotient when dividing with 4096 also gives the hand category. Evaluator gives each hand 16-bit integer ranking, which can be used for comparing hands (bigger is better).Multiple cards are combined in Hand objects which makes the actual evaluation fast and allows caching of partial hand data.Evaluates hands with any number of cards from 0 to 7 (with less than 5 cards any missing cards are considered the worst kicker).OMPEval is a fast C++ hand evaluator and equity calculator for Texas Holdem poker.
