- « - Denotes impressive results
-
-
-
- The CPUTEST and the above data is hereby released into the Public Domain.
-
-
-
- This "project" was started to help me gain a better understanding of "raw"
- CPU "power". I wanted to upgrade my motherboard from a 286-12MHz and wanted
- to see how a high-end 386 (cheaper) compared to a low-end 486 (more expensive).
- Originally, I was only testing 8086-instructions, but as I moved into the
- realm of testing higher-end machines, I added 32-bit specific instructions.
- I really didn't like those benchmark programs that simply rate the "effective"
- performance of a machine. I wanted to know HOW they got those results and
- WHAT they were testing. The three (3) specific areas I'm testing are very
- low-level - no matter what language you use, you will generate code that
- uses these instructions.
-
- This program can be a benefit to both technicians and buyers. I use it
- to test the effective CPU strengths of my clients computers. If they have
- a wimpy CPU, this'll smoke it out. Technicians can also benefit by testing
- their own computers, comparing performance and perhaps saving money by
- buying faster, cheaper computers. (One client complained of lack of speed
- on his 486 server. A quick run of CPUTEST showed his computer was running
- slower than my 286-12MHz! Solution: Check his TURBO switch - it was off)
-
- If you find this program useful, all I ask is that you please drop me
- either EMAIL via CompuServe (76447,3500) or a post card, describing your
- system (what kind of CPU, MHz, how much RAM, DOS version & how much
- CPU Cache - if any). CPUTEST.EXE appends your results (as well as one-line
- user-entered comment) to CPUTEST.TXT.
-
- >-----------------------------------------------------------------------------<
- > Please run it 3 or 4 times, to get a consistant reading. If you have <
- > cache, please alter your CMOS settings to turn your cache off and run the <
- > program another 3 or 4 times. This will give a more accurate performance <
- > of your CPU. Finally, if you could run a series of tests with the external <
- > cache off and internal cache on, that would make the effects far more <
- > revealing. In other words, run three sets of tests - one with all cache on,<
- > one with all cache off, and one with ext off/int on. Please report all <
- > results. <
- >-----------------------------------------------------------------------------<
-
- I also encourage you to pass this program and results chart along to
- friends & BBSes. The wider it circulates, the more precise results I can get.
-
- In return, I'll maintain your name and address in my database of
- "contributors". Hopefully,this will become a widely accepted "benchmark"
- program. While I would like to send a new results chart to everyone that
- sends in their information, I simply couldn't afford the postage. However,
- if you send in a *bunch* of results from different computers, that would
- weigh heavily in your favor of getting a printout in the mail. However, I
- *do* maintain a current results chart (and the latest version of CPUTEST.EXE)
- on Compuserve (GO IBMHW, LIB 4, [76447,3500]TEST.ZIP) and I will update the
- list monthly. Please prefix the filename with my CIS number, as there are
- two different programs named TEST.ZIP in that forum.
-
- Please U.S. Mail results (if you cannot CIS EMAIL) to:
- Tony Doimeadios, Post Office Box 431, Brunswick, GA 31521
-
- Include a SASE and I will mail you the most recent copy of the results chart.
-
- With the majority of CPU's begin represented in this RESULTS file, the
- level of user-submitted results are beginning to slow down. As a result, I
- will be updating this CPUTEST.TXT every *other* month instead of monthly.
- The next update will be at the end of April, 1994.
-
-
- Thank You for all of your support.
-

- HOW TO USE YOUR RESULTS
-
- By themselves, the numbers generated by running CPUTEST on your computer
- aren't worth much. It doesn't reveal your "effective speed", how many times
- faster you are over an original IBM-PC, or anything like that. Your results
- should be taken in context with the results from the above chart to see how
- you "rank". A lot of people ask, "Can't you derive a common set of numbers
- for a particular type of CPU and let that be the 'Standard'?" A quick look
- at the chart for the 80386DX will tell you that the numbers range from a
- high of 50 to a low of 15! CPUTEST wasn't written to determine "CPU SPEED",
- merely measure performance.
-
- My original question, "What motherboard gives me the most bang for the buck?"
- can be answered by examining this chart. Why should I spend $350 for a
- 486DX-33 when for $105 I can buy a 386DX-40 and get (VERY!) comparable
- results?!? The only negative factor in buying the far cheaper 386DX-40
- would be you would be yet another generation behind the "newest" CPU, meaning
- you wouldn't have access to the small handful of 80486-specific instructions.
- I have YET to see a product that writes SPECIFICALLY for the 486.

- OBSERVATIONS
-
- So far I've found that after a certain point, MEMORY MOVES do not
- gain any appreciable increase in speed. Looking at the chart, you
- can see that there isn't much difference between a 486/33 and a 486/50.
- Perhaps after a certain point, RAM chip speed (70 ns, 60 ns, etc.) is a
- "barrier" to higher performance.
-
- However, the REGISTER OPERATIONS *do* pick up a lot from having a bigger CPU
- (486 -vs- 386) and faster cpu speed (50 MHz -vs- 33 MHz - a 50 MHz brings in
- 29 clock ticks, while a 33 MHz takes 44! A difference of *15*!).
-
- Also, caching doesn't help *as much* with register operations (30% faster)
- as compared with memory moves (56% faster).
-
- The 80486 is optimized differently than previous chips. It performs
- MEMORY LOCATION-TO-REGISTER operations more efficiently than REGISTER-TO-
- REGISTER.
-
- The EISA bus (486-50MHz) performed the REGISTER operations identically to
- the ISA bus of the same speed, however the MEMORY MOVES were much faster.
- The system has 70ns RAM, so that helps support the idea that the EISA
- design is what is making it have very good performance in the area of
- memory moves. In fact, a computer-knowledgable person told me that the
- 32-bit data bus is why the MEMORY MOVES were so good.
-
-
-
- SOAPBOX
-
- I have read that the chip makers are trying to make their cpu chips run
- programs (that are made with "inefficient" compilers) faster. There are
- a limited number of cpu registers, and some compilers are not optimized
- enough to use these registers (which had been the fastest way to move info
- from 8088 to 80386) effectively. Therefore, since the compilers aren't
- "smart" enough to use them, the chip makers are devoting more square area
- of silicon to allow these "memory-location to register" moves to run faster
- (fewer clock cycles) than "register-to-register" moves. This gives the
- impression that the programs are "running faster than ever before".
-
- [ ]
- [ this is why the newer chips have such a heat problem ]
- [ more silicon=more power=more heat ]
- [ ]
-
- What's happened, however, is that the tail is wagging the dog (so to speak).
- Intel stated the required number of clock cycles for every instruction of
- their cpu. (Most) compiler makers did not sell compilers that optimized
- the final EXE for the fewest clock cycles. They used inefficient
- instructions and sold millions of copies of their compilers.
-
- Is this bad? No, not really. Is there a downside to all of this? Yes.
- The only people that are really irked are assembly language programmers.
- Used to be, they could sit down and hand-tool a specific function that would
- beat the compiler's similar function (*if* it had something similar). Now,
- with each instruction having a different "priority" from cpu to cpu, to
- simulate the same level of performance increase, we would have to detect the
- cpu (no big deal) and branch to one of *5* routines. We would have one for
- the 8086/8088, one for the 80286 (we can safely skip the 80186/80188), one
- for the 80386, one for the 80486 and one for the Pentium. We could almost
- have two sections - 80386 and below, and 80486 and higher. There are very
- strong similarities between the 80486 & the Pentium, and I imagine the
- Hexium? (80686) would be closely related to the Pentium. Therefore, the
- optimizing routines for the 486+, while not identical, would be close enough
- for the Pentium not to matter.
-
- Is this really worth worrying about? It depends. Wouldn't it be nice if
- OS/2 2.1 only needed 10 meg instead of 40 meg for HD storage?? Of course!
- I contend that it will ALWAYS be nice to have highly efficient DEVELOPMENT
- TOOLS. The better your tools, the better of a product you can make.
- What if your favorite brand of C++ compiler compiled in 1/2 or 1/3 of the
- time?? Time=Money. However, I'm afraid the future holds for more powerful
- processors optimized for inefficient compilers, and computers with tens of
- megs of RAM. In that kind of world, who needs efficiency?
-

-
- Below are pieces of information I'd like to have. If you don't know, that's
- fine. The more I know about your system, the better weight I can put with
- your results. I've included an example for you to use. If I can get enough
- responses with motherboards, I'll prepare a secondary chart, grouped by
- motherboard namebrand. This might help with selection of a namebrand when
- you go to make your purchase. Thank you!

- CPU CHIPS
-
- First, a little review: the 8086 is the base processor that was used in the
- IBM XT; all later processors include its instruction code as a subset of their
- code. It is a 16-bit processor that can address 1 MB of memory or devices. (16
- bits gives 256 possible combinations, hence the 256-character extended ASCII
- set) The 8088 is internally the same, but accepts 8-bit instructions; it was
- used in the IBM PC because 8-bit components were less expensive than 16-bit
- ones. The 80186 is a later design that is essentially the same as the 8086.
- All of them are logically (to the operating system) the same chip.
-
- The 80286 is also a 16-bit processor, and (I believe) can address 16 MB
- (OS/2's original memory limitation). It can also use an external coprocessor
- for higher order math functions (the 80287).
-
- The 80386 is a 32-bit processor that has a 32-bit address space. It also
- incorporates virtual mapping of addresses, so non-contiguous memory locations
- can be processed as single blocks of memory. It can access an external
- coprocessor for higher order math functions (the 80387). This processor was
- later called the 386DX.
-
- The 386SX is a 386DX internally, but accepts 16-bit instructions and so can be
- used in a computer with less expensive 16-bit components. This has the effect
- of being slower than a full 32-bit chip. Logically, however, it is still a
- 386DX.
-
- The 80486 integrates an 80386(DX), a 80387 math coprocessor, and a small (8K)
- memory cache on one chip; essentially it's a faster processor than a 386 of the
- same speed. This is now known as the 486DX. Note that logically it's really a
- fast 386 with a math chip.
-
- The 486SX is a 486DX except that its math coprocessor doesn't work. That means
- logically it's a fast 386DX _without_ a math chip. (Math chips are mostly only
- used by compilers and 3-D graphical modeling apps, not the average power user).
-
- The 486DX2 is a 486DX that processes instructions internally twice as fast as
- it accepts them. Logically it is also a fast(er) 386DX with a math chip.
-
-
- Now we start splitting hairs:
-
- The 486SLC is an IBM design; it's a 386DX on a circuit board with some cache
- memory, a power saving controller, and a cache controller so IBM markets it as
- logically being the same as a 486SX even though it's really a 386DX. However,
- as we now realize, logically a 486SX and a 386DX are the same so it's a six of
- one, half a dozen of the other situation. In any case, it's kind of a fast
- 386DX or a slow 486SX, depending on how you look at it, but it's internally a
- 386DX without a math chip.
-
- I am unsure but believe the 486DLC is the same as the 486SLC only it adds a
- math coprocessor to the circuit board; this makes it logically the same as a
- fast 386DX with a math chip.
