Intel 486SX-16MHz Benchmark and Upgrade to Kingston Turbochip at 133MHz (AMD 5x86-133)

CPU Galaxy 2023-01-13 | In this Video I am showing the slowest 486 which was ever produced. The Intel 486SX at 16 MHz. We will do some intesive benchmarks on a propper board of its time, an early 486 board with just ISA bus.
The second chip which will get tested and benchmark is the Kingston Turbochip which is an upgrade chip and contains an AMD 5x86 at 133 MHz and will give our old board an exreme boost like from 0 to Hero :-)
The usual benchmark programms as speedsys, norton sysinfo and checkit as well as some games are completing here our results.

286 Boost! Upgrade to 386 or additional Cache ~~ODD PARTS~~

CPU Galaxy 2021-07-02 | In this video we will review and test 2 odd upgrade possibilities for 286 plattforms. First a CPU upgrade which allows to put a 386 CPU into the PLCC socket of an 286 board. Second a upgrade adapter which should provide you some cache on your old 286 system. Everything will get tested and benchmarked. So be curious about the outcome and how much performance we could get by using those weird parts.

NEC V20 D70108D VS 8088 CPU Benchmark + Windows 1.01 Booting

CPU Galaxy 2021-04-17 | In this video we will compare the NEC V20 µPD70108 against the Intel 8088 CPU. The V20 has a completely different design and double amount of transistors as the 8088 cpu. With some benchmarks we are going to see how big the performance increase is if you switch to a V20 CPU in your XT Class Machine. Byside that the highlight, booting the first version of Microsoft Windows Version 1.01 on the V20 CPU. I will also show some old DOS Games as well clear charts of the benchmarks.

Soviet K1810VM88 VS Intel 8088 Benchmark on high integrated Philips Mainboard.

CPU Galaxy 2021-04-09 | In this video we will check if the Soviet 8088 clone also called K1810VM88 is just a copy or something seperately designed. I would expect to measure a slight difference in performance. After that video, you will know it. We will use Checkit, Norton Sysinfo and fractint to find exatly that out. The motherboard is out of a Philips P3120 XT Computer and the best integrated XT board I have seen so far. You will also see and hear a rare 8-Bit IDE HDD made by Seagate, ST-325X.
Guest Star in my video is my wife Alisa, she is Russian and has to defend of course the solid soviet technology from the past.

CPU Galaxy 2020-10-16 | #vintagecomputer
In this video we have a benchmark battle of 5 different 486DX4 100 MHz CPUs. Intel, Cyrix, AMD, TI, ST...
Who will win the race?
At this benchmark we will also test Intel and AMD with WT (Write Trough) Level 1 Cache and WB (Write Back) Cache to see how big the difference is.
We are combining here synthetic benchmarks as well as 3D benchmarks and games. All based on DOS 6.2.
The board I am using is a Asus PVI486-SP3. This great board is supporting all different brands of 486 cpus.
Enjoy the video and please don't forget to subscribe. :-)

Vintage CPU Rating - How to rate a collectible CPU?

CPU Galaxy 2020-06-08 | Here I want to introduce a kind of rating I created for vintage cpus and chips. You will see now regulary a detailed rating of several special and common chips on my channel. This should help any collector to get the most asked question answed "is my cpu somehow special and how much is it worth?"..
So there is a big community out there of chip and retro computer parts collectors and I just want to share my experience I built up for over 20 years.

Download here a spreadsheet where you can see details of all ratings I published so far. At each rated cpu you will find also the link to the related Youtube video.
