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.
