AMD’s 7800X3D and 7950X3D hold the top spot in CPUs for gaming, not because they have the most cores or the highest clock speeds, but because they have the most cache. But what is CPU cache, anyway?

Optimizing any system is a multi-layered problem, but when it involves a processor there are at least three levels to consider. Architects must be capable of thinking across these boundaries because ...

If multiple devices, such as the CPU and peripherals, access the same cacheable memory region, cache and memory can become incoherent. This is illustrated in Figure 7. Suppose the CPU accesses a ...

When talking about CPU specifications, in addition to clock speed and number of cores/threads, ' CPU cache memory ' is sometimes mentioned. Developer Gabriel G. Cunha explains what this CPU cache ...

In the eighties, computer processors became faster and faster, while memory access times stagnated and hindered additional performance increases. Something had to be done to speed up memory access and ...

In the early days of computing, everything ran quite a bit slower than what we see today. This was not only because the computers' central processing units – CPUs – were slow, but also because ...

As the demand for high-performance processors continues to grow and semiconductor scaling laws continue to show their limits, the need for processor optimization is inevitable. As I explained in a ...
