AMD Zen3...FOUR THREADS PER CORE

The CPU has been the heart of every PC since Intel’s x86 processors became popular over two decades ago. Yet the CPU does have weaknesses,the greatest of which is their relatively linear data execution. Graphics processors, by comparison, consist of many small cores that execute data simultaneously. This makes it easier for them to perform certain tasks, like video decoding and 3D graphics.

Both Intel and AMD know this, and have for some time. In response they’ve combined the strengths of both CPUs and GPUs, resulting in a new type of product called the APU.

What is an APU? The term APU stands for Accelerated Processing Unit. At the moment, this is a term that only AMD is using for its products. Intel’s recently released update to its processors also qualifies as an APU; Intel simply seems unwilling to use the definition. That’s understandable, since the company has been known as the world’s leading CPU maker for years.

An APU is simply a processor that combines CPU and GPU elements into a single architecture. The first APU products being shipped by AMD and Intel do this without much fuss by adding graphics processing cores into the processor architecture and letting them share a cache with the CPU. While both AMD and Intel are using their own GPU architectures in their new processors, the basic concepts and reasons behind the decision to bring a GPU into the architecture remain the same.

AMD and Intel wouldn’t go to the trouble of integrating a GPU into their CPU architectures if there weren’t some benefits to doing so, but sometimes the benefit of a new technology seems to be focused more on the company selling the product than the consumer. Fortunately, the benefits of the APU are dramatic and will be noticed by end users.
