There are three levels of Processor Cache viz; L1, L2, and L3. The more L2 and L3 cache your system has, the faster the data will be fetched, the faster the program will be executed, and the more ...

One of the greatest challenges facing the designers of many-core processors is resource contention. The chart below visually lays out the problem of resource contention, but for most of us the idea is ...

When shopping for a new CPU, you're likely to come across many different CPU specifications, such as cores, clock speed, TDP, ...

Cache, in its crude definition, is a faster memory which stores copies of data from frequently used main memory locations. Nowadays, multiprocessor systems are supporting shared memories in hardware, ...

The year so far has been filled with news of Spectre and Meltdown. These exploits take advantage of features like speculative execution, and memory access timing. What they have in common is the fact ...

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 ...

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 ...

The disk cache in OS X can sometimes use a fair amount of the system's RAM, and clearing it can help you figure out how much RAM your applications and system processes are using. Topher, an avid Mac ...

For interest's sake I've included the memory bandwidth results here for Kaby Lake-R, which are slightly improved on Kaby Lake thanks to DDR4-2400 support. Core i7-6500U 324 MB/s 149 MB/s 92 MB/s Core ...
