45 Years Intel 8088
Hey folks,
45 years ago, exactly on June 1st, 1979, the i8088 was born. This date marks a unique milestone in the x86 CPU history.
Let´s explore this milestone a bit more in detail together. In this video I talk about the CPU evolution of the 70s and early 80s starting with Intel´s first microprocessor. The 8088 is an 8-bit version of the 8086. IBM chose this CPU due to several reasons that I will touch in the video. As a result, the 8088 can be regarded as THE grandfather of all PC processors having been used in the original IBM PC and IBM XT. From then on, x86 CPUs were set as standard and still is!
I will also decap an i8088 and look at the microstructures using my metallurgical microscope. The microstructures of the CPU were identified with the reference of Ken Shirriff´s blog about the 8088 (Ken Shirriff's blog: 8088 (righto.com).
I also could make a quick stitch of the processor using my 4x objective (+2x optical lense) resulting in 50 pictures to be stitched.
I hope you enjoy this birthday video dedicated to the Intel 8088!

    People who didn't come to computers until micros don't apreciate how remarkable the 8088 was. Prior to that cpu width and memory width was always the same. 32 bit bit mainframes had 32 bit wide memory, 16 bit mini compuers had 16 bit wide memory. The 8088 was the first processor to separate cpu width and memory width.

  • @KennethScharf
    @KennethScharf 11 วันที่ผ่านมา

    The 8 bit bus actually doesn't reduce the chips performance by 1/2. Due to the chips internal fetch queue and the fact that it takes several clock cycles to perform each instruction (super scalar processors didn't arrive until the Pentium), means that the 8 bit cpu can almost catch up with the operations of the 16 bit. It DOES depend on the actual instruction mix, but the actual performance of the 8088 is a bit better than 50% of the 8086. It's close enough to justify the lower cost of the 8088 vs the performance of the 8086, especially if one can run at a higher clock speed. IBM was initially specing a PC design using the 8085 processor, but Bill Gates at Microsoft suggested that they use the 8088 instead, pointing out the greater memory addressing, and that software development for the newer processor would not cost any more than for the 8085. Big Blue took his suggestion to heart, and the rest is history.

      @@johnrehwinkel7241 ARM is not RISC. This is a deception. ARM has dedicated instructions for converting Java Script floats to integers, it has SIMD instructions which are distinctly a CISC thing that were introduced in the Intel Pentium with the MMX instructions, and ARM v8 has more instructions in its ISA than probably any CISC chip from the 1980s and definitely more than the original Intel Pentium. I had counted by hand the instructions from the Intel Programmer's manual for the Pentium versus modern ARM. I would also like to state that modern CPUs do not spend most of their chip area on the logic. Even a fully fledged Ryzen CPU's chip area is mostly cache and not the logic. There is no advantage for someone to choose ARM over x86 in the desktop, laptop, or server arena. Power efficiency? If you see ARM do better than x86 in energy efficiency it's because they either have better manufacturing at their disposal such as when Apple reserves newest technology from TSMC so AMD can't get their hands on it or the comparison makes no sense. For example, comparing a mobile chip with a desktop chip is silly because both Intel and AMD have established power consumption of 65 watts or higher on their desktop chips. Their laptop chips easily go as low as 6 watts such as the Intel N100 and if you undervolt they can go even lower. The Steam Deck is one of those devices where you can lower the power consumption to just 5 watts and games still perform ok.

    I stopped at the graph for waay too long, cause it's too messed-up in history: 1. Why is 8-bit overlapping with 4 and 16-bit, but 32 and 64 are not overlapping? Overlapping is good if you account for product life, but that is extremely difficult to assess. If you account for the last product released, maybe, but it's still wrong for the next reasons. 2. How come you graph the 386SX, but not the original 386 (later renamed to DX after SX launch)? 386 was in 1986, 386SX was 1988. 3. 386SX is a 32-bit CPU, just line 8088 and 80188 are 16-bit, not 8-bit (assumption of reason for ovelapping 8/16). 8085 is the last 8-bit in you graph.

      Hi, thanks for your feedback. First of all the data is entirely my own database based on all CPUs that I have. I had to delete many data points to keep clarity. The data points are introduction dates on the monthly basis, btw. the 386SX is clearly wrong and I had corrected this in my PIII and 486 anniversary videos. Now to the challengin topic of overlapping architectures (4-,8-,16-,32-bit): so as said it is not about the life time (some CPUs were still produced 20 years after their launch date), so it is about the internal and the bus structure. Is the 8088 and 80188 a true 16-bit chip? I disagree to your view. :) as we learned crippling down 16 bit CPUs to a 8 bit data bus looses 50% of performance, but it does not mean it is a bad or not succesful chip. Another reason for me to keep the 8-bit era spanning to the mid 80s is that many will simply remember that this was still the 8-bit time. Thanks again for forcing me think this through again!

    I just find your channel and I must say that is quite interesting. However, I have a curiosity. Everyone knows that the original IBM PC and IBM XT had discrete TTL logic ICs and few dedicated ICs that later were bundled in the chipsets (2-3 larger ICs depending the manufacturer). I would like to see if one can identify the original 8086 support ICs in one of those early chipsets (DMA controller, clock generator, etc or even the floppy / HDD controller, UART, PIO, etc). There are many that look at the CPUs die but I did not find anyone interested on the chipset dies. It would be interesting I guess.
