    Speed Tests... CFX v the Rest

    Here are the results of some performance comparisons between Casio CFX9850G, Casio Algebra FX2.0, Sharp EL9600, Hewlett Packard 38G, TI82 and TI83+ models.
    The total times (in seconds) for all four tests were:

    CFX74s
    FX2.086s
    EL9600249s
    HP38G197s
    TI8276s
    TI83+76s

    The following four tests were used to benchmark the execution speeds of some common calculator functions. Should the time to enter instructions/keypresses also be factored in? The individual test results are below!

    INDIVIDUAL TESTS

    FUNCTION GRAPHING

    1. The Test. With both axes scaled from -10 to 10, the calculators drew the 10 functions shown below:
    2. The Results (in seconds):
      CFX37s
      FX2.039s
      EL960076s
      HP38G60s
      TI8238s
      TI83+37s

    STATISTICS

    1. The Test. Bivariate statistics. Before the test began, one list was filled with integers 1, 2, 3, ...., 200 and a second filled with 200 random numbers betwen 0 and 1. The test time was the sum of the individual times to complete these operations:
      • Draw a scatterdiagram
      • Calculate the coefficients of the least squares regression line and correlation
      • Draw the least squares regression line
      • Calculate the bivariate summary statistics
    2. The Results (in seconds):
      CFX13s
      FX2.012s
      EL960040s
      HP38G61s
      TI8218s
      TI83+25s

    CALCULUS

    1. The Test. Evaluate the sum of the three integrals shown below.
    2. The Results (in seconds):
      CFX4s
      FX2.05s
      EL960063s
      HP38G47s
      TI824s
      TI83+6s

    PROGRAMS/MATRICES

    1. The Test. Execute a simple program which loops 200 times, in each loop displaying the number of the loop, multiplying two 2x2 matrices (filled with single digit integers) and storing the result in a third 2x2 matrix (no display of matrices).
    2. The Results (in seconds):
      CFX20s
      FX2.030s
      EL960070s
      HP38G29s
      TI8216s
      TI83+8s
