Meaning it makes each pyhsical core run as two cores. So where are they getting this new one that splits it in to four. As far as I know, this tech does not exist. Not for mass production anyway.
I had heard they were using one of the AMD octo cores previously. Which tbh are awful compared to Intel cores, but still.
You're getting multi core processors and multi threading processing mixed up, which is a easy mistake to make
Multicore processors are at a hardware level and have been around for many years as I'm sure everyone know
Multithreading is a software / code level operation where the thread is a basic unit / process / function ready for execution via the CPU, schedules / queue for processing via the OS. You are right, you can multithreading on a single core, if the OS supports context switching, I.e. it makes it appear to the application that concurrent processing is happening on two or more threads but what it is actually doing is the OS switching processing cycles between multiple threads sequentially
Obviously, multithreading is much simpler when you have multiple physical cores to truly process different threads concurently but context switching will still happen and the processing capacity is not linear, there are diminishing returns to multiple cores. Fundamentally, according to chip architecture, each core will eventually share resources on the processors such as the BUS & the registries etc. Also, from an application point of view, you need to optimize the code, little point in having multiple cores if each process needs to access the same piece of code on the disk, the I/O off the disk will be sequential
Having said all of that, the new box sounds like a 4 socket, quad core, x86 workstation / server hosting a cut down version of windows. Nothing implausible or far fetched about that, technology is already available and deployed in Business, I have designed systems based on this architecture myself
The only question is how much will the box cost, it doesn't sound very cheap
