Microsoft Excel 2007
Microsoft Office Excel 2007 is a powerful and widely used tool with which you can create and format spreadsheets and analyze and share information to make more informed decisions. It allows you to import, organize and explore massive data sets within spreadsheets and then communicate your analysis with professional-looking charts. Excel 2007 also provides tools to “see” important trends and find exceptions in your data. Legit Reviews has two benchmarking tests that we do on Microsoft Office Excel 2007.
The first workload executes approximately 28,000 sets of calculations using the most common calculations and functions found in Excel. These include common arithmetic operations like addition, subtraction, division, rounding and square root. It also includes common statistical analysis functions such as Max, Min, Median and Average. The calculations are performed after a spreadsheet with a large dataset is updated with new values and must re-calculate many data points. The input file is the 6.2 MB spreadsheet seen above.
Benchmark Results:Lots of people use Microsoft Office at work and home, so this is an important test for many of our readers. Many people don’t run 28,000 sets of calculations at once, but if you do the CPU will determine how fast the task is completed. The Intel Core 2 Duo E8500 can’t compete with the Intel Core 2 Quad Q6600 in this test, but it completes the task 15.5% faster than the Intel Core 2 Duo E6750.
The Black-Scholes model is used in our second Excel test to calculate a theoretical call and put price using the five key determinants of an option’s price: stock price, strike price, volatility, time to expiration, and short-term (risk free) interest rate.
This workload calculates the European Put and Call option valuation for Black-Scholes option pricing using Monte Carlo simulation. It simulates the calculations performed when a spreadsheet with input parameters is updated and must recalculate the option valuation. In this scenario we execute approximately 300,000 iterations of Monte Carlo simulation. In addition, the workload uses Excel lookup functions to compare the put price from the model with the historical market price for 50,000 rows to understand the convergence. The input file is a 70.1 MB spreadsheet and with 10 times the calculations of the first test, this one should take a bit longer to complete.
Benchmark Results: With 300,000 iterations of Monte Carlo simulation taking place in this benchmark it takes all the processors a bit longer to finish as it puts a good load on the system. The Intel Skulltrail system is in a league of its own as it completes the task in less than ten seconds. The Intel E8500 was 22% faster than the Intel E6750 in this benchmark.
