Google and Samsung are in the midst of developing a new chip for their mobile phone platforms. Qualcomm has dominated the mobile phone processor category for years, but Apple began to move away in favor of their own iOS-based processors, which became the foundation for the M1 design. Now Google and Samsung are making the same move, taking mobile processor development in house.
Sam joins Leo to talk about new processors for Hyundai electric vehicles. Using Nvidia Parker SOC chips, Hyundai will put them in all their future cars with 14" displays for powering their infotainment systems. Sam says that Nvidia has some amazing SOCs available with 30 trillion operations per second: 8 core ARM chips drive the whole thing with machine learning: 10GBit per second ethernet bus. It's a practical supercomputer for the road.
Dave wants to know why Apple is switching away from Intel. Leo says that Apple is moving on from Intel because they can't provide low power, high performing chips that Apple wants. The reason is that the development of processors by Intel has been stalled at 10nm, while Apple has gotten very good at developing ARM chips that are just as powerful for their mobile platforms (they are 5nm now).
Chip is looking to build a new computer and is looking for current guides to building medium/high-end PCs. Leo recommends PCper.com and their hardware leaderboard. The leaderboard will help recommend all the right components and is a great place to start one's research. AnandTech and certain subreddits can also help with additional note-taking.
James wants to be able to upgrade his computer to a new processor and motherboard. Should he go with Intel or save money and go with AMD? Leo says that AMD has kept Intel innovating and the prices down. However, for the last few years, Intel has surpassed AMD. But AMD is bouncing back with the Ryzen processor platform, which is very affordable. So it comes down to what's more important, price or performance?
Intel has run up against a wall in Moore's Law that said that the number of transistors in a processor would double every 18 months. In the last few years, Intel has been up against a wall, not being able to double the speed. But a recent breakthrough has created a transistor using a single atom! That will enable processors to become faster and smaller, using very little energy.
Brian is looking to get a new Intel 8th-gen Core laptop. Leo says that the last few generations of processors really haven't had much of a boost in performance, making it really difficult to justify buying a new PC just for the processor. But if one needs a new PC, Leo recommends the Thinkpad X1 Yoga. It's a 2-in-1 that allows customers to turn it into a tablet.
Henry wants to buy a new Mac and wants to know if it's true that processor speed isn't as important as hard drive speed. Leo says that's true. Processors are really fast now and there's only a dimes worth of difference between them for every day use. It's better to get an i5 and then spend more money on a faster hard drive and better screen. Leo says that a 21" iMac with an SSD is best for speed, but a Fusion Drive would give him more space plus a speed boost.
Jerry has been playing around with overclocking his computer. Could he run it too high? Leo says absolutely. When he starts to see unreliable performance, then he'll know he's clocked it too high. But when overclocking, he'll need to cool it down more and some even rely on liquid cooling. So keep an eye on the temperature, and when he starts to see more crashing, then he'll want to take his foot off the gas a bit.
Alex is thinking about getting an AMD processor because they seem more affordable. Leo says they are, but really not enough to justify the performance gap. Also, Broadwell processors aren't out yet, but they will certainly be even faster. Leo likes that AMD is out because it keeps Intel honest, and pushes Intel to keep innovating, keeping prices down. That's what competition is for. But sadly, AMD is just not as fast.
Leo recommends consulting PCper.com to research the components for building his own PC.
