1. Isabell

Updated, July 28 2023. Isabell has now been upgraded faster than ever! :) With a fast Intel i5 7600K CPU,
16 GB memory and a fast MSI GeForce GTX 1050Ti, 4 GB graphics card and a 480 GB SSD hard drive with
Windows 10 Pro. Microsoft Flight 2020 and my other games now run fast and smoothly.

My favorite "computer games" are Microsoft Flight 2020 Deluxe and Phoenix 5.5 R/C flight simulator. I am not
so advanced but I think it is very relaxing and fun. Microsoft Flight 2020 is an awesome simulator! :) I have a
Logitech Extreme 3D Pro joystick to steer it. My favorite "birdie" is the nice two engine propeller aircraft Baron 58.
Sometimes I also run the old but good car racing games Grid 2, Kartcraft and the nice motorcycle game Ride.

2. Linnea

Q1 2021. I also have a good Lenovo Intel i5 notebook (15") with Windows 10 Pro.
Sometimes also with Ubuntu Linux on another SSD hard drive.

3. Other digital equipment

4. Benchmark results for some old PCs

Some old PC Mandelbrot Mflops CPU benchmark results

Here is presented some CPU benchmark results with my old Mandelbrot DOS program (Mflops) for some
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 modern Intel Core 2 Quad and Intel i7
Quad CPUs and computers. Note, Mandelbrot calculations contains +, - and *, but no /. Divisions usually
take more than one clock cycle on most CPUs. The Mflops results for Pentium CPUs (and higher) are
rounded downwards to nearest integer Mflops.

The Mandelbrot program can be downloaded here and used as a benchmark test. It presents the used CPU-
time and number of Mflops. It needs some modifications for older computers and must be recompiled for
16-bit Intel CPUs. Intel 386 and higher CPUs should work fine. Note, 32-bit Windows operating system
is required for this program to run. It doesn't work on 64-bit OS but can be recompiled for that. The source
code for the Mandelbrot program can of course also be compiled on any Linux and Unix computer. It is
written in standard C and can be compiled on most platforms.

Here are the Mandelbrot Mflops benchmark results (Intel 286/287 to i7):

Intel Pentium II (686) 333 148.000 444.44 DJGPP 4.1.0 gcc -O3 32-bit
Intel Core 2 Quad Q6600 (on one core) 2400 1555.000 647.92 DJGPP 4.1.0 gcc -O3 32-bit
Intel i7 2670QM Quad (on one core) [2] 3100 2324.000 749.67 DJGPP 4.1.0 gcc -O3 32-bit

[1] The Intel Pentium Pro CPU was added January 27 2014.
[2] The Intel i7 2670QM CPU was added February 25 2015. It has a main clock frequency of 2200 MHz and goes up to a turbo frequency
of 3100 MHz when the benchmark test is run. It was checked with the Intel Turbo Boost Technology Monitor tool for Intel i5 and i7 CPUs.

5. 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?

6. 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.
