The performance of one Horizon processing element can be quantified by user operations per instruction, the instructions per tick, and the basic clock rate. Assuming there is sufficient parallelism within a problem, the performance of one PE can be multiplied by the number of PEs contained in the Horizon system. For a 256-PE Horizon the expected sustained performance is in the order of 50 giga user operations per second for problems with sustained parallelism of 8,000 to 12,000 instruction streams.
