-
- USER INTERFACE
-
- You may control this program with a mouse and/or keyboard.
- To scroll the text in this box, click on the up and down arrows in the text
- box border, or press the up/down arrows, or page up/down keys.
- To change the scale of the speed bars (normally yellow), click the left or
- right mouse button while the mouse cursor is on top of the bar. Left button
- increases the scale to make the bar shorter (violet), and right button
- decreases the scale to make the bar longer (cyan, or light blue). Press F3
- and F4 to increase/decrease the CPU and FPU scales, or F5 and F6 to change
- the video scale.
-
- If you are running on a monochrome system, you will not be able to discern
- what CPU type or speed scales are active from a distance because color is
- used for those purposes.
-
- Press F1 for help, F9 to recalculate video speed, F10 to toggle the beeper
- on and off, and Esc to exit the program.
-
- You may run the program with one or more command line parameters separated
- by spaces to affect operation:
- SPEED /B - bypass initial help screen
- SPEED /NV - no video (disable video test)
- SPEED /Q - quiet (disable beeper)
- SPEED /40 - run for 40 seconds and exit
- SPEED /B /NV /Q /40 - all of the above
-
- THE TESTS
-
- The system speed tests tell you the most important information about the
- computing performance of your system: the effective speeds of the central
- processor unit (CPU), floating point unit (FPU, math coprocessor),
- and video display circuitry. Although hard disk access and data transfer
- rate affect system performance, we excluded those tests because they do not
- affect actual computation speed.
-
- CPU/FPU Tests
-
- The CPU and FPU speeds show performance relative to an IBM AT with a 6 MHz
- 80287 math coprocessor chip installed. For example, if the display shows
- CPU speed to be 22.53 MHz, it means an IBM AT would have to run at 22.53
- MHz to have the same computing performance as this computer. If the display
- shows FPU speed to be 40.25 MHz, it means an IBM AT would have to run
- its 80287 math chip at 40.25 MHz to have the same floating point math
- calculation performance. The speeds are NOT the actual CPU/FPU clock speeds.
-
- CPU Test
-
- The CPU test forces the processor to show the effect of instruction cache.
- It is thus more accurate than previous versions. On color systems, the
- background display is gold for 8088 and 8086 CPUs, green for 80286,
- blue for 80386, and red for 80486. This allows you to see from a distance
- what kind of CPU is running the system. The display also shows in text the
- type of CPU installed.
-
- FPU Test
-
- The FPU test shows a value only if a math chip is installed or built into
- the CPU. Where possible, it shows the manufacturer of the chip (e.g., Intel,
- Cyrix, IIT). Note that the 80486 has an internal FPU, but other CPUs do not.
- The test accurately reflects the higher performance of a closely coupled
- CPU-to-FPU architecture.
-
- Screen Updates
-
- The program runs both CPU and FPU tests continually, and updates the display
- about 4 times per second. The speed will drop if you run another application
- concurrently or change CPU clock speed. You will be able to see the system
- speed degradation caused by multitasking or background network accessing,
- or by taking the sys
- tem in and out of turbo mode.
-
- Clock Speed / Multitasking
-
- Multitasking does not affect actual CPU clock speed, but allows less time
- for the speed test to run; turbo mode actually changes the CPU clock speed,
- and thus affects the performance of both multitasking and the speed test.
- Some systems do not have a turbo mode, but those that do usually allow you
- to invoke it with a front panel switch or the keyboard (normally
- Ctrl-Alt-plus or Ctrl-Alt-minus).
-
- Variable Readings
-
- As the test runs, you may notice the CPU and FPU MHz values changing
- slightly. This does not mean your system clock is running erratically,
- but rather that test results are being rounded off, and occasional
- interrupts in the background are using CPU time.
- If you want the fastest possible readings, you should boot DOS on the
- computer with no drivers or resident programs installed. Such software can
- cause the CPU to work on special tasks in the background while the speed
- test runs in the foreground. The special tasks will take CPU time and cause
- the speed test to give lower readings than it should.
- Large temperature changes can cause PCs to vary in performance
- characteristics. As a result your computer may run faster when it is cold
- than when it is warmed up.
-
- Video Test
-
- The video test checks pure data transfer rate from the CPU into video memory.
- It thus shows the maximum speed at which data can be read and displayed.
- The video test detects most popular video adapter chipset types, and displays
- the type and manufacturer on the screen. If it cannot determine the
- manufacturer, it shows just the generic type, such as monochrome, CGA, EGA,
- or VGA.
-
- Video / System Design
-
- The video test results are affected by video adapter design, CPU speed, and
- system board design. For example, some systems have fast I/O bus speeds
- and allow a fast data transfers to video adapters. Others, even some with
- very fast CPU speeds, have slow I/O speeds and thus slower display rates.
- Much of the power of a fast video adapter can be wasted if it is used in a
- slow system. On the other hand, a slow video adapter can impede the faster
- systems, giving diminished performance in display-intensive applications.
-
- Video Runs Once
-
- The program runs the video speed test only once, at the beginning. This is
- partly for aesthetic reasons, since it makes the display look unattractive.
- You may re-run the video test by pressing F9 (recalculate). You will need
- to do this if you take the system in or out of turbo mode while the normal
- speed test is running, because video speed can be affected by CPU speed.
-
- Video BIOS
-
- The video test does not show the effect of BIOS on display speed because
- most popular high-performance applications write directly to video memory,
- and do not use BIOS. Furthermore, most super VGA adapters come with a
- program that loads display BIOS into system RAM for maximum execution speed.
-
- SCALES
-
- All of the test results are shown on variable scales. The default scale
- values are different for each CPU type, but the default speed bar is always
- yellow. This allows the program to show how the performance of your
- system compares to the scale limits for your processor type.
-
- Thus, if you view the screen from a distance, the program accurately renders
- performance information without the exaggerated effect of display wrap-around
- or logarithmic scaling used in earlier versions of the program. If you see a
- yellow speed bar, you are seeing the default scaling for your CPU type.
- If you are running on a computer that is slow for the class of CPU it uses,
- the speed bars will be short. If the computer is fast, the speed bars will
- be longer. If the bar is too short or too long for your liking, you may
- change its length by adjusting the scale.
-
- However, when you change the scale, you will also change the color of the
- speed bars to either cyan or violet. This will allow distant viewers to
- recognize that the system is not using the default scale and that the
- length of the bars have a different meaning.
-
- If the bar is too long on a scale, you have a very fast computer. To shorten
- it and turn the bar violet, press F3 or click the left mouse button while the
- cursor is on top of the bar. F3 expands CPU and FPU scales, while F5 expands
- the video scale.
-
- If the bar is too short on a scale, you are running on a relatively slow
- computer. To lengthen the bar and turn it cyan, press F4 or click the right
- mouse button while the cursor is on top of the bar. F4 shrinks CPU and FPU
- scales, while F6 shrinks the video scale.
-
- HISTORY AND STANDARDS
-
- From 1984 through early 1993 the original Landmark CPU Speed Test (tm)
- gradually gained prominence and became the de facto world standard for
- measuring PC computing speed. There are several reasons for its rise to
- popularity:
-
- 1. Standard - it compared the speed of the computer it ran on to the speed
- of the first and only de facto standards that ever existed for personal
- computers: the IBM PC and the IBM AT. IBM never changed the architecture
- of either computer, but replaced them with the PS/2 line in 1987 and took
- the PC and AT out of production. Since IBM will never change the PC or AT,
- those will always be stable standards of comparison for PC performance,
- and Landmark will be the performance measurement standard. The original PC
- used an Intel 8088 CPU and optional 8087 FPU running at 4.77 MHz. The
- original AT used an Intel 80286 CPU running at 6 MHz, and a later version
- ran at 8 MHz; in both versions the optional 80287 math chip ran at 6 MHz.
-
- 2. Visibility - the Landmark speed bar that reached horizontally from left
- to right across the screen was visible and relatively readable from a
- distance of 15 to 30 meters (50 to 100 feet). This made it ideal for
- dealer showrooms and trade shows, so manufacturers and resellers enjoyed
- using it to show off their computer's speed.
-
- 3. Credibility - it was the most accurate benchmark test on the market
- because it considered a variety of factors that other programs did not, and
- it showed performance relative to the PC and AT. Other benchmark programs
- gave unreliable or misleading information:
-
- Norton System Index (SI) was too simple and overrated AT performance relative
- to the PC.
-
- MIPS (millions of instructions per second) used an instruction mix that was
- somewhat arbitrary.
-
- Whetstone, a test of general computing combined with floating point or
- scientific math calculations, was originally written in FORTRAN, so the
- results were badly skewed by both compiler efficiency and the ratio of
- floating point math instructions to arithmetic and loop instructions.
- Dhrystone, a test of general computing performance, was originally developed
- to test ADA compiler efficiency, but was converted to the C language for
- execution on the PC. Because of the plethora of C compilers in use, it
- suffered from the same kind of skewing as Whetstone.
-
- 4. Results - The speed test displayed its results graphically with fixed
- scaling, and it beeped while it gave continuous screen updates. All the
- other programs, such as SI, MIPS, Power Meter, CheckIt, and QA Plus, ran
- through once and stopped. Thus, in real time it showed how much system
- performance degraded during network accesses or other multitasking program
- activities. Furthermore, the instant update gave immediate feedback to
- users, and gratified them that the system was actively running. Finally,
- benchmark graphic displays in QA Plus and CheckIt automatically scaled test
- results so that their speed bars had no meaning when viewed from a distance.
