They are “soft” in the meaning they aren’t fixed: they may be altered readily. By comparison, a computer’s hardware–both the bits and pieces where it’s made (along with the peripherals) such as the printer and mouse (you plug it in to it)–will be still pretty much mended whe...
Overclocking is a good way to boost gaming performance, because it can helpincrease FPS. While many games are “GPU bound,” meaning that most calculations happen on the graphics card, a significant part of gaming performance also depends on processor performance. But remember that while an overc...
an array of four 32-bit integers that's filled with the values of the EAX, EBX, ECX, and EDX registers (in that order). The information returned has a different meaning depending on the value passed as thefunction_idparameter. The information returned with various values offunction_idis pro...
综合来说,GetStackTrace()存在与JMX一样的SafePoint Bias。更多安全点相关的知识可以参考《Safepoints: Meaning, Side Effects and Overheads》。 那么,如何避免SafePoint Bias?社区提供了一种Hack思路——AsyncGetCallTrace。 基于JVMTI + AsyncGetCallTrace实现 如上节所述,假如我们拥有一个函数可以获取当前线程的调用...
The information returned has a different meaning depending on the value passed as the function_id parameter. The information returned with various values of function_id is processor-dependent. The __cpuid intrinsic clears the ECX register before calling the cpuid instruction. The __cpuidex ...
When you look at your computer’s motherboard, you may notice a CPU OPT one close by once you find the CPU FAN header. Although at first glance its meaning is clear, its exact function can be a complete mystery to new hardware enthusiasts. Let’s demystify that CPU OPT header and expla...
Benchmarks are often split into single-core and multi-core scores. Single-core scoresare more relevant for games and applications that are lightly threaded, meaning they rely on a single core to process many — but not all — instructions. ...
tablets instead utilize a system on a chip (SoC) which is a chip that packages the CPU alongside other components. Intel and AMD both offer CPUs with graphics chips and memory stored on them (you may have heard ofAMD APUs), too, meaning they can do more than just standard CPU functions...
implementation is 1 MB, but subsequent processors may have different sizes. In addition, the L2 cache is "exclusive", meaning that the L1 caches' contents do not reside in our L2 cache, thus increasing the effective size of the L2 cache over the "inclusive" approach of competitor ...
Retiring metric represents a Pipeline Slots fraction utilized by useful work, meaning the issued uOps that eventually get retired. Ideally, all Pipeline Slots would be attributed to the Retiring category. Retiring of 100% would indicate the maximum possible number of uOps retired per cycle has bee...
