Hi, this is Wayne again with a topic “The Most Important CPUs Ever”.
Let’S begin today’s video at the beginning, by talking about the intel 8086 released on june 8th 1978, it wasn’t intel’s first cpu. That distinction goes to the 4004, but the 8086 was the front runner, the cpu that sits inside your desktop or laptop pc right now. Unless you on a mac, a newer mac anyway, you see the 8086 introduced the x86 architecture, the dominant design scheme for the past 40ish years that underpinned almost every consumer cpu from intel to amd. Now that could be shifting nowadays with the growth of non-x86 designs like apple’s new m1 chip, but x86 still dominates the pc market and it all started with the 8086..
Of course, it originally only ran at a clock speed of 5 megahertz, which is about a thousand times slower than a modern cpu before you even consider like all the architectural improvements since then, but nonetheless, the x86 architecture became a mainstay in large part, because the original Ibm pc used the intel 8088, a slightly modified 8086 that ibm was able to get in large quantities for a relatively low price. As the ibm pc became an industry standard, the x86 architecture took off and was eventually licensed out to other chip makers, including amd speaking of amd. Let’S move on to our next featured cpu, the amd athlon 64., although it was intel that created the original 16-bit x86 architecture and refined it into a 32-bit platform. Emd was the first to develop a 64-bit version of x86, which they released for the consumer market in 2003.. Athlon 64 was quite ahead of its time, considering that in 2003 windows xp ruled the world, and most people were still using 32-bit platforms. However, 64-bit computing quickly became popular toward the end of the 2000s, which was very important as it allowed systems to access more than four gigabytes of memory at once. Without you know, trickery, but even lower end systems today, typically having at least eight gigs of ram staying on 32-bit platforms would seriously hamper the experience for many users.
Athlon 64 was still on the shelves until 2009, but during that time another big time innovation came onto the scene. That was just as important as the transition to 64-bit i’m talking about dual core processing and we’re actually going to mention two chips in this section. The intel pentium xtreme 840, which came out in april 2005 and the amd athlon 64 x2, which debuted the next month, the extreme edition 840, actually wasn’t even that complicated of a design. It was really just two xeon cores intel’s server lineup, just mashed onto one chip or glued together, as you might call them. Uh amd meanwhile, was a little bit more forward. Thinking as the f164x2 had a direct link between its two cores to speed things up where intel cores had to pass information through the front side bus in order to coordinate their activity, that’s bafflingly, slow trust me amd’s, offering also had the advantages of being more power. Efficient and it didn’t even need a brand new motherboard, it could just work on existing boards with a bios update, so team, red or green back then was actually ahead of team blue in the multi-core cpu game for a while, even though intel pulled way ahead in Market share a few years later, but we’d be remiss if we only talked about desktop and laptop cpus. What about the chips that live inside of our phones? These were developed very incrementally, but arguably the most important one was the arm.
Cortex a8 released in 2005.. Now the cortex a8 isn’t just one chip arm doesn’t actually manufacture chips, but rather they license out the designs to third parties. Although the cortex a8 was far from arm’s first chip, it was probably the first that became broadly popular in consumer gadgets. Cortex a8 cores were featured in the first ever samsung exynos mobile cpu, as well as the apple a4, which powered the iphone 4 and the original ipad.
Cortex a8 also featured super scalar technology, meaning it could execute more than one instruction per clock cycle, as well as a branch predictor that was much more advanced than preceding designs. This meant that the chip could anticipate system needs ahead of time more effectively, representing a significant leap forward in performance. Although arm chips were already popular on smartphones, the a8 really cemented arm’s design as a go-to for mobile devices as subsequent cortex models enabled many of the features we’ve come to expect on modern smartphones, as well as performance that has closed the gap significantly between pcs and Mobile devices in 2005, there were fewer than 2 billion arm-based chips sold this jumped to over 21 billion in the year 2017..
Of course, there are plenty of notable chips that we didn’t have time to cover today. So let us know down in the comments which ones you’d like to see in a future episode. Maybe we’ll uh get to do those a little bit later on thanks to seasonic for sponsoring today’s video, season’s prime ultra titanium, pc power supplies feature ultra high efficiency, with their 80 plus titanium rating they’re, fully modular, featuring hybrid fan, control to control overall fan noise and Fluid dynamic fan bearings and they have up to a 50 000 hour.
