1. Information about some old PCs and some benchmarks for them

January 17 2012. I have made a somewhat difficult decision. I realize that I can't take care of all
remarkable old computers that I come across. So from now on I will specialize on old (and new) PCs.
More information and some images of the boxes mentioned below will come soon.

Regarding old PCs I have a wonderful HP Vectra 286/12, Victor V386MX 20 MHz, Victor V486MX DX2
50 MHz, noname Intel 486 DX4 100 MHz and a nice Intel Pentium machine running at 200 MHz. Even the
slowest of these computers are fully capable of running my graphical "ssdosmix" DOS programs found
here, although not so fast of course.

Some old PC Mandelbrot Mflops benchmark results

February 5 2014. Benchmark with Intel Pentium Pro 200 MHz processor added.

Here is presented some benchmark results with my old Mandelbrot DOS program (Mflops) for these old
computers. It should be noted that that the program performs about 75 % better compiled with DJGPP
32-bit than with TC 2.0 16-bit in this test on the same machine (see the 486 DX4 at 100 MHz). The 286
computer can only run 16-bit code and a system file was missing when I tried to run the DJGPP version
on the 386 machine. The benchmark results are also compared with a modern Intel Core 2 Quad computer.
I will soon put these programs available for download together with some instructions for use. Here are the
results:

2. Crayina 1 - my incredible "super computer"! :-)

September 18 2010. Just for fun I called this Victor 486 computer Crayina 1 - my incredible
"super computer"! :-) But of course the real Cray 1 super computer had significantly better
performance (especially on vectorized code). Some very good information about it is found here.

To be fair the Cray 1 has a vector performance of up to 133 MFlops, which actually more
corresponds to an Intel Pentium II CPU at 333 MHz or so. The latter performs 148 MFlops
in my Mandelbrot fractal program (compiled with DJGPP gcc 4.1.0 -O3). The code fits into
the L2 cache of the CPU and is not able to vectorize. The Intel 486 computer at 50 MHz
only performs 3.2 MFlops with this program. I actually thought it was a little bit better...
An Intel Pentium CPU at 200 MHz performs 49 MFlops with this program, which means that
it is about four times faster than the 486 per clock cycle counted. The Pentium CPU also
has two execution units and L2 cache, while the 486 CPU only has only one execution unit
and no L2 cache. As a comparison my new Intel Core 2 Quad Q6600 CPU at 2.4 GHz performs
1555 MFlops with this program on one core. All programs were run under Windows or DOS.

Sometimes I think the computers and operating systems of today are somewhat "too good",
user friendly, streamlined and elegant and almost a little bit boring to work with. Everything
just works perfect. I am old enough to miss the good old DOS and Windows 3.11 times
when you have to spend man-days to get things work! :-) I also remember how happy I was
when I managed to set up the windows environment under Linux for the first time (autumn
1994). So just for fun I found and set up this nice and very cute Victor 486 computer from
the beginning of the 90th. The small and slim TFT monitor is of course much more modern,
but it fits quite well to this computer. An image of this nice setup as well as power consumption
data will come soon.

Unfortunately the hard drive (120 MB) seems not to work on this computer, so I have to load
DOS 6.22 into the primary memory of the computer. It works quite well and then I can easily
run my old graphical "ssdosmix" C-programs (found here) on it! :-) Perhaps I will install
Windows 3.11 or even OS/2 on it if I get the hard drive to work. Note, after investigating this
further it seems as if the problem is not the hard drive itself. Actually the CMOS battery seems
to not work so the BIOS "forgets" it's hard drive settings also after a computer reset...

3. Isabell i5

April 4 2013. New Isabell. Finally I came across this wonderful little Intel i5 mini tower computer to a very
reasonable price! :-) It is really very fast and has quite a lot of memory. Some π y-cruncher, SSBENCH
and graphics benchmarks for it and some other computers are presented in sections 8 and 9.

April 9 2013. I have now upgraded Windows 8 Release Preview to genuin Windows 8 Pro on Isabell.

May 2013. I have now bought Tomb Raider 2013 and it is an awesome game with stunning graphics.
Actually one of the best, most exciting and funniest games I ever have played! :-) Lara Croft in this game
is also a very amazing and sometimes very human character. I have now also connected the sound from
the computer to a very good stereo setup.

June 2013. I have now also bought Crysis 3 which is a really awesome and exciting game with the best graphics
found among computer games today! :-) I am not a great gamer and sometimes behold the beautiful and
fascinating surroundings in the games as "art". Perhaps not the way the games are supposed to be played,
and it takes long time to go through, but I really enjoy it! :-)

December 2013. Isabell has now been upgraded to Windows 8.1, which is very nice and fast.

March 22 2014. Finally I have upgraded Isabell to a "full-fledged" gaming, multimedia and movie machine with
a fast Seagate 240 GB SSD hard drive and an awesome ASUS GeForce GTX 760 graphics card. My favorite
games for the moment are Tomb Raider 2013 and MS Flight 2012. Sometimes I also relax with some races with
Grid 2 2013 and Dirt 3 2011. All these games are amazing and have stunning graphics! :-)

August 18 2014. I have now bought a 27" Samsung S27D390HS monitor. It uses PLS technique and has the
best image quality I have seen on a full HD monitor or TV so far! :-) Especially set to "Cinema" and "Game"
mode at the same time. The Epson AcuLaser C1700 colour laser printer is also highly recommended! :-) It makes
awesome printouts with very beautiful colours also on ordinary A4 printer paper. Regarding games I am now running
Phoenix (5.0) R/C aeroplane and helicopter simulator. It is very fun and realistic and has awesome graphics! :-)
An ordinary (and quite old) JR 7-channel radio is used and connected to the computer via a special USB adapter.
It works very well.

New! October 8 2014. By a small "mistake" I have to reinstall Windows on Isabell. So I actually took the oportunity
to install Windows 10 Release Preview on it. It seems really extremely good! :-) I have also started to take my first
steps with X-Plane 10 flight simulator and the Amsterdam (EHAM) airport. It seems awesome and is downloaded
and bought via Steam! :-) More about these things later.

New! October 13 2014. My new "computer stereo" DIY kit setup is under contruction and consist of an awesome Quad 405
V2 amplifier clone (2 x 100 W), with a special feedback system minimizing the distortion, and very good Jensen JPT-1802
speakers (2 x 150 W). I must say I am surprised, but this stereo system has a so fast, detailed and clean sound response,
so I have never heard something similar before! :-) For the moment only one amplifier channel PCB with pre-mounted
components, heatsink, the toroid trafo, capacitors and the rectifier are mounted on a wooden tray. I will mount the whole
amplifier kit in a nice Aluminum box with pretty cable wiring as soon as I can. More about this later and perhaps some
images (probably also on my "Technical projects" web-page).

New! Added October 17 2014. Of course I still also have my other stereo system consisting of an amazing Linsley Hood
class A transistor amplifier (2 x 10 W) and Swedish Corus Delta speakers (2 x 50 W) with crystal clear sound. It is probably
still my best stereo system for moving and classical music. Sound, music and audio systems interest me, so I think it is nice
to be able to shift between different systems depending on type of music and my own mood.

4. Lisa

January 2013. Unfortunately the motherboard on old Melissa was broken so I set up another nice
computer called Lisa with Fedora 20 Linux. The computer is used for administration of my web
pages etc and sometimes C-programming and some LaTeX document writing. I use the vi (or vim)
text editor and the gFTP file transfer program, which are very good, and of course good old gnu gcc
C-compiler and sometimes Allegro game C/C++ library for graphics under Linux (and Windows).
When I compile graphical C-programs with Allegro for Windows I actually use good old Microsoft
Visual C/C++ 6.0 on an old Windows XP machine. It works well and the resulting programs runs
fine also under Windows 7 and 8 (both 32 and 64 bit). However newer compilers of course
produce faster code.

5. Rebecca i7

December 2013. Rebecca is a very nice and fast ASUS X53CS Intel i7 Ultrabook (with defektive and removed
display) wich I came across very cheap. It has a very powerful graphics card and I run it as a desktop computer for
games etc. More information and some benchmarks to come. But I can already mention that it runs for example
Tomb Raider 2013 i and MS Flight 2012 very fast and smooth with full HD resolution. The power contact on the
motherboard of the computer was also broken, so I actually have to solder in a cable from the charger directly
in to the motherboard. It was quite a tricky business so I was really very glad when it worked! :-) This was also
a reason for the very low price of the computer. I bought it partly defective from a friend.

6. Amanda

Januari 2014. A very nice and portable ASUS UL30A Ultrabook with good battery time.
The size of it is really very handy and it is thin, pretty and very light weight. I got it cheap
because it was in used condition and the display was broken. But I had a replacement.
I use it it as a good travel computer and for some electronic steering applications.

New! October 17 2014. Amanda is a nice and very power efficient computer, but not so fast.
So I have now put a small SSD hard drive (32 GB) and 4 GB memory in it. I also installed
Windows 10 Release Preview (32-bit). These things actually cheer it up a bit! :-) I use 32-
bit OS because some of my electronics steering programs require that.

An image from Internet of such a wonderful little computer is found here.

8. Some multi core π benchmarks with y-cruncher 0.6.1 and 0.5.5

Some multi core 64-bit benchmarks with y-cruncher 0.6.1. This wonderful program calculates many mathematical
constants (i.e. π and many others) to millions or billions of decimal places. Many thanks to the author!

The CPU times refere to the "Total time" including base conversation etc but not writing data to the hard drive.
The calculations are also made "All in ram", i.e. no hard drive swapping.

Note 1. C2D and C2Q are Intel Core 2 Duo and Core 2 Quad processors respectively.
Note 2. The Core 2 Quad Q6600 processor could not run SSE4.1 instructions.
Note 3. The Core 2 Quad Q6600 processor has larger L2 cache memory than the Q9300 which makes the speed difference between them quite small in this test.
Note 4. These computers have DDR2 6400/800 memory. Perhaps the Core 2 Quad Q9300 processor could benefit from faster DDR2 8500/1066 memory?


9. Some CPU and graphics benchmark results for Windows, Linux and some other OS

Here are presented some CPU (32-bit) and graphics benchmark results for Windows
and Linux and some other OS for my PCs and some other computers.

SSBENCH (SIint and SIfp) is found here and 3D-Mark 2001 and 2003 can
be downloaded for free from Futuremark Corporation. Results marked "-"
are not possible to run. For SSBENCH under Windows the compiler DJGPP
(gcc) was used. There is very little difference in performance between gcc
4.1.0 and 4.3.2 under the same OS. For the 3D-Marks default settings were
used (i.e. 1024 x 768 resolution). Unfortunately do these benchmarks not
work under Linux.

Note. The SSBENCH benchmark is run on a single CPU core also on multi core machines.
