Hi, this is Wayne again with a topic “GLASS CPUs ARE COMING.”.
When you think of high performance CPUs, you probably think about how we’ve shrunk transistors over the years to the point where we can fit an insane number of them onto just one chip. But did you know that the substrate the processor dice sits on is also very important? Not only do substrates give the delicate D structural support, they also carry signals and connect the D to other parts of the system on most CPUs. The substrate is primarily made from epoxy and fiberglass. That’S plastic, reinforced with woven glass fibers, but Intel is moving towards using substrates that are based on refined glass. Instead, it’s more like what you picture when you think of glass like like actual glass, these glass core substrates have advantages that can allow for higher performance than the current fiberglass and epoxy organic substrates that have served us well since the early 2000s.
One big one is how glass substrates react to heat, because chips are often heating up and cooling down as different kinds of workloads are put on them or organic substrates stretch and relax in unpredictable ways. Actual glass is stiffer and a lot more resistant to Thermal warping. This extra stability means you can put more routing holes in the substrate for extra power and data connections, not to mention better signal Integrity, which is increasingly challenging as our transistors become smaller and smaller. No matter what we do to stop them for a practical example.
Think about how topend server processors suck down hundreds of watts of power, but run at only around 1 volt. If you remember your high school physics, this means you’re having to push through lots of current at one time, which is pretty inefficient and leads to some of that power getting lost because glass is more stable than organic substrates. At higher temperatures, you can put in a greater number of data and power connections which improves both signal integrity and power efficiency. It’S a pretty cool feat of engineering, but what does this actually mean for you, the average computer enjoyer, we’ll tell you right after we thank the sponsor of this video touring College.
If you feel like educating yourself in the field of data science, analytics engineering and AI touring is an accredited online college, offering diverse courses designed to help you succeed in the real world, their courses are self-paced and project-based, meaning you control your own study schedule as an Exclusive offer Turing College will randomly select one of the first 100 people that went through their application process and offer them a full scholarship towards a paid course follow the link below and get edicated part of the reason Intel is so concerned about power, efficiency and Signal Integrity is due to how much electricity and data goes through data centers that do lots of AI processing and, since most of us use some kind of cloud AI service these days. Switching CPU substrates is one of several developments that will help ensure our AI capacity can continue to grow. In fact, the new substrates lead to a theoretical doubling of the data rate between two chips in a Data Center and will even help with communication between chiplets on the same package due to allowing smaller distances between the bumps that connect.
The substrate to the die glass is also easier to flatten out than organic substrates, which makes manufacturing significantly simpler and combined with the advantages we’ve already discussed. Chip makers should end up being able to put more processing dyes on one chip, as well as make those dyes larger, giving us more compute power per package. Just gets getting better and better, but are glass substrates also going to be coming to the CPUs we have in our home PCS? The short end answer is yes, but we may be in for a bit of a weight, as the limitations that glass substrates are meant to address are more of a concern for data centers. Right now, Intel is looking at rolling out data center chips with the new substrates in the second half of this decade, while we’ll likely see consumer chips towards the end of the decade. Until then, though, there’s nothing wrong with using fiberglass. I mean it’s good enough for surfboards hey.
What are you doing here at the end of the video you rascal, hey thanks for watching keep that like the video, if you liked it dislike it, if you disliked it check it out. Our other videos comment below with video suggestions and don’t forget to subscribe and follow already it’s been. It’S been.
