8088 & 8086 CPUs... Why 16 bit Came Before 8 bit [Byte Size] | Nostalgia Nerd

Shiny

Ok ok

Shame the 8088 didn’t get released with 8 KHz, 8 bit bus, 8 bytes ram with 8 byte flash with 8 byte eeprom with 8 instructions in 1988

Finally, found the answer! Thankyou!

Short answer: price. Thanks for watching ;)

Minimal integer adalah 8 bit

8008, 8080 and 8085 were all 8-bit processors from Intel, with the 8086 being Intel's first 16-bit processor (and therefore the beginning of the popular x86 microarchitecture that we still use today), and also the 8088 is actually a 16-bit CPU, but gelded in order to make it cheaper to build the computer (16-bit circuits required extra DIP chips to form the Northbridge and Southbridge circuitry on the motherboard - long before both Northbridge and Southbridge become integrated, on a single die for each components - nowadays, the Northbridge circuitry is integrated on the CPU die or implemented as a separate Northbridge die in recent Ryzen CPUs), so the cost was also a factor for IBM as they were trying to enter the home PC business back in the day.

Excellent video 6 years later.

So basically, a 1970s Cyrix 586. Or, a 1970s Road Apple.

Umm ... the 8088 was an an upgrade path offered to 8085 system users. The IBM PC precursor used the 8085 so the first IBM PC was an upgraded existing design. Note the PC 8-bit card slots are same as for IBM earlier 8085 offering.

Take a drink every time the word "eight" is said

Anyone else hates it when they call it "the eight oh eight six" - when those authentically from the 80's knew it as the "eighty eighty-six"?

I disagree... the 8 bit 8085 came long before the 16 bit 8086.

He's doing it on purpose.

The 8088 seems similar to the 6809, though it was the 6502 that diverted me from the 4004 and 8008, although I couldn't avoid the 68000.

So, it s really an 80816

can i have a link to that video that you posted at the tintro of the vid? where he talkes about the datapaths and clocks

you should do benchmark on both cpus

Yes, same number of transistors between 8088 and 8086, but the 8088 can address only 64KB of RAM. The 8086 up to 1MB.

A friend of mine kept saying the 8088 was newer and thus faster than the 8086, until I referred him to this video.

the 8086 had a 20 bit address bus actually and used segment registers to store the base segment and an offset from that base segment.

It seems like they could have made a single CPU, that depending on the availability of data paths, could process either 8 bits or 16 bits data.

...but every time he says "eight" you drink

wow, that alot of 808s in 3 minutes ;)

die is a death word it should be dye

So many eights...

So what they are saying is that the 8086 was way ahead of its time, by two years infact.

As much as I love watching your videos, (really brings me back to the late 70's into the 80's, when I used a lot of the computer gear you've talked about), hearing you say "Eight-Eight-xx-xx" over and over again almost made me punch my $1100 38inch monitor. Please, going forward, don't do that again, "Eighty-Eight-xx-xx" works so much better, and doesn't make the watcher want to cut their own wrists after the first 30-seconds ;-)

Cheers!

the 8088 was used in the IBM PC and XT, the 20286 was used in the AT, I read that the 8086 didn't come out until the lower PS\2 models, these coming after the AT

My first time on a pc.. was an 8088

Our computers are so junky, imagine if your brain has 16 or 8bit bus memory

Are there any chips that still have 8088 compatibility like the x86 line has?

That explains the difference between an IBM compatible XT and a 286 AT.

The reason stated in the video for the 8088 is incorrect. The 8088 was a custom concession to IBM. The support chips were not ready for the 8086 at the time that IBM was designing the IBM PC so Intel modified the 8086 to be the chip vendor for the IBM PC.

Isn't the "visualisation" of 16 bits vs 8 bits missleading? Its shown as twice the size, but it is infact 256 times the size.

Ah but what about the 8008?

I had an 8086. No hard drive, 5.25" floppy disc, CGA display

My first computer IBM PC XT. Intel 8088, DOS 1.1

They used this same trick with the 386sx to save money and reuse 286 motherboards. Basically put a 32-bit cpu on a 16-bit bus. OEMs loved it because they could advertise a system as being a 386, yet re-use the stock from the 286 machines and thus saving money.

Oh ye gods! The success of the 8088 for Intel was inversely proportional to the experience of the consumers. This step backward for pricing purposes was such a painful performance loss. My first PC, a Tandy no less, with its amazing Tandy color and sound, should have been stunning for the time ... if not for this noticeable performance loss from the 8088. It was not a smart pairing. So most of my gaming continued to be on the C=64. LOL

how come they never made an anniversary 8088 800Mhz 8bit like the i7 8086K cpu lol

The 8086s die was sideways :/

eight o eight eight, eight o eight eight,eight o eight eight,eight o eight eight,eight o eight eight,eight o eight eight,

i am having nightmares, with big and tall eights, chasing me to push me in their narrow door so narrow that i will not be able to breathe properly an die from asphyxiation.

ever heard of 8080 ? 8085 ? Dummy.

ate oh ate ate.

The guy at the beginning is explaining like a teacher sHoUlD

All I hear is 8 zed 8
