It might be hard to find one person who has enough time and motivation to meet for regular language practice. In that ca

Also, even though it might sound exaggerated: Beware of a person’s intentions. I have made the experience of meeting guys as platonic language partners who then asked me to go to the movies with him or to date him. That was simply not what I wanted, so I usually cut the contact. Of course, there are some people for whom a simple tandem partner becomes a life partner. It is up to you to decide if you are potentially up for a romantic relationship. This goes for all genders!

That is the reason why you see ARM CPU-makers such as Ampere making CPUs such as the Altra Max which has a crazy 128 cores. This chip is specifically made for the cloud. You don’t need crazy single-core performance because in the cloud it is all about having as many threads as possible per watt to handle as many concurrent users as possible.

For Apple this is simple. They control the whole widget. They give you, for example, the Core ML library for developers to write machine learning stuff. Whether Core ML runs on Apple’s CPU or the Neural Engine is an implementation detail developers don’t have to care about.

There are two approaches to this. One is to add more CPU cores. From the point of view of a software developer, it is like adding threads. Every CPU core is like a hardware thread. If you don’t know what a thread is, then you can think of it as the process of carrying out a task. With two cores, a CPU can carry out two separate tasks concurrently: two threads. The tasks could be described as two separate programs stores in memory or it could actually be the same program performed twice. Each thread needs some bookkeeping, such as where in a sequence of program instructions the thread is currently at. Each thread may store temporary results which should be kept separate.

So heterogeneous computing is part of the reason but not the sole reason. The fast general-purpose CPU cores on the M1, called Firestorm, are genuinely fast. This is a major deviation from ARM CPU cores in the past which tended to be very weak compared to AMD and Intel cores.

ver, that there will be gaps in platform support. These gaps require us to have a flexible architecture that puts modern web standards at the heart of our engineering but retains the ability to patch in polyfills/native implementations where required.

I do not recommend continuing a tandem “partnership” with a person you feel uncomfortable with. A German friend of mine used to have a British tandem partner who was constantly nagging her and really didn’t sound like a nice person to hang out with. I personally would not want to meet that person only for the sake of language learning.

But we are quickly moving away from that world. In the new SoC world, you don’t assemble physical components from different vendors. Instead, you assemble IP (intellectual property) from different vendors. You buy the design for graphics cards, CPUs, modems, IO controllers, and other things from different vendors and use that to design an SoC in-house. Then you get a foundry to manufacture this.

Here we get a big problem with the Intel and AMD business model. Their business models are based on selling general-purpose CPUs, which people just slot onto a large PC motherboard. Thus computer-makers can simply buy motherboards, memory, CPUs, and graphics cards from different vendors and integrate them into one solution.

In principle, a processor can have just one core and run multiple threads. In this case, it simply halts one thread and stores current progress before switching to another. Later it switches back. This doesn’t bring much of a performance enhancement and is only used when a thread may frequently halt to wait for input from the user, data from a slow network connection, etc. These may be called software threads. Hardware threads mean you have actual extra physical hardware such as extra cores at your disposal to speed up things.

Now you got a big problem, because neither Intel, AMD, or Nvidia are going to license their intellectual property to Dell or HP for them to make an SoC for their machines.

Back in the ’80s, it was easy. Just increase the clock frequency and the instructions would finish faster. Every clock cycle is when the computer does something. But this something can be quite little. Thus an instruction may require multiple clock cycles to finish because it is made up of several smaller tasks.

Apple, in contrast, is on the complete opposite end of the spectrum. Apple makes single-user devices. Lots of threads is not an advantage. Their devices are used for gaming, video editing, development, etc. They want desktops with beautiful responsive graphics and animations.

Sure Intel and AMD may simply begin to sell whole finished SoCs. But what are these to contain? PC-makers may have different ideas of what they should contain. You potentially get a conflict between Intel, AMD, Microsoft, and PC-makers about what sort of specialized chips should be included because these will need software support.

The problem with this is that the developer has to write code to take advantage of this. Some tasks such as sever software are easy to write like this. You can imagine processing each connecting user separately. These tasks are so independent from each other that having lots of cores is an excellent choice for servers especially cloud-based services.
