- New features of Bench 6.0
-
- Program Design
-
- The program design of Bench 6.0 is now object-oriented.
- Thanks to their use of Borland C++ and Assembler test
- routines, the tests are now modular and can be utilized with
- different user interface programs. The Zinc Interface and
- Codebase ++ database libraries are the main libraries used
- in this iteration of the PC Labs benchmarks. All told, there
- is over 100,000 lines of code in Bench 6.0
-
- User Interface
-
- The user interface for Bench 6.0 now supports VGA and
- EGA graphics as well as text mode displays. The program
- automatically determines the display adapter and mode of the
- system in which it's running and adjusts itself accordingly.
- Mouse support, drop down menus, windows and graphs are all
- features of the Bench 6.0 user interface. (Note: if Bench
- 6.0 does not detect an EGA or VGA adapter, it defaults to
- text mode. Graphics tests are not available in text mode nor
- is graphing of results possible in text mode.)
-
- Internal Database
-
- A database engine is now an integral part of Bench 6.0.
- This engine keeps track of both tests and test results. All
- results can be logged to the database and recalled later for
- modifications and/or additions. This also allows them to be
- used for comparison against other machines as well. Though
- the results are automatically saved to .DBF (dBASE format)
- files, they can also be saved to ASCII files and be printed
- on a printer. As PC Magazine tests machines, the results
- generated by the Labs will be made available on PC MagNet
- for downloading so that they may be used for comparison
- purposes.
-
- Modular Test Design
-
- Because of the modular test design, tests are loaded
- and unloaded from memory as needed. This means that the
- number of tests supported by the program is limited by disk
- space instead of memory.
-
- New Test Metrics
-
- Bench 6.0 now measures performance as throughput rather
- than elapsed time (as in Bench 5.6). Results are expressed
- as operations/second, kilobytes/second, characters/second or
- pixels/second as appropriate (except for the disk access
- tests). Every test runs for a minimum of 10 seconds. This
- ensures a high degree of accuracy in the results (+- 1%).
- For this reason, however, there is no direct correlation
- between the results from Bench 5.6 and Bench 6.0.
-
- New Tests
-
- To better measure the performance of today's graphics
- adapters, we have enhanced the existing text mode tests and
- added several new EGA/VGA register-level graphics tests.
- These tests help to determine whether the graphics adapter
- is set to run in 8- or 16-bit mode as well as measuring the
- graphical performance of these adapters. Designed for PC
- Labs by Spirit of Performance Inc. (73 Westcott Road,
- Harvard Ma. 01451), these tests perform graphics fills and
- Bitblts (bit block transfers) - two of the most common
- functions for graphics adapters.
