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?

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 ...

The CPU’s cache reduces memory latency when data is accessed from the main system memory. Developers can and should take advantage of CPU cache to improve application performance. Modern CPUs ...

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 ...

A cache is a special storage space for temporary files that makes a device, browser, or app run faster and more efficiently. After opening an app or website for the first time, a cache stashes files, ...

At some point you may have heard someone say that for gaming you need X amount of cores. Typical examples include "6 is more than enough cores," or "you need a minimum of 8 cores for gaming," due to ...

Designers of today's high-performance multi-client SoCs struggle to achieve the best possible performance/watt for their designs. Every generation of product must improve the customer's user ...
