But it doesn't end there. They have multiple cores and threads, and they can overclock and throttle their frequency automatically depending on things like thermals and power delivery.<\/p>\n<p>Manufacturers guarantee a boost clock only when a processor isn't thermally or power-limited. Several factors can affect a CPU's boost clock:<\/p>\n<ul>\n<li>The silicon quality<\/li>\n<li>Your cooling<\/li>\n<li>Thermal paste quality<\/li>\n<li>The workloads you're running<\/li>\n<\/ul>\n<p>And even if your processor does boost to its advertised boost clocks, it might very well be that it holds this frequency only for a couple of milliseconds here and there.<\/p>\n<p>Just long enough so manufacturers can advertise 5+GHz clock speeds on the CPU's packaging and potentially mislead the unsuspecting buyer. To maintain sustained boosts, you need premium cooling solutions (air\/liquid) that can dissipate heat fast enough.<\/p>\n<p>Of course, these new features bring a lot of benefits as well, but for a new buyer it raises a lot of questions first:<\/p>\n<p>For example, what are base and boost clock speeds? Is it better to shop for a CPU with a higher base clock speed or a higher boost clock speed? Which workloads depend more on either one or the other?<\/p>\n<p>We\u2019ll explore these questions, and more, in this article, and provide you with guidance on what clock metrics are important for your specific workload.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Are_CPU_Clock_Speeds\"><\/span>What Are CPU Clock Speeds?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>First things first: What are clock speeds? Are they an important metric for comparison, or do they hardly matter in terms of practical performance?<\/p>\n<p>A CPU's speed is measured by its internal clock in &#8216;ticks' or clock cycles. The faster it can &#8216;tick,' the faster it can get work done in a set amount of time.<\/p>\n<p>Each one of these cycles consists of a pulse of either an on or off switching of transistors, which is synchronized by an internal oscillator (internal clock).<\/p>\n<p>The maximum frequency of these pulses is measured in Hertz (Hz), with modern-day CPUs performing in the Gigahertz range (each gigahertz reflecting a billion cycles per second).<\/p>\n<p>So, a CPU with a 4GHz clock speed is capable of performing 4 billion ticks in a single second. Now, performing a simple operation might take just take a couple of cycles\/ticks, while a more complex operation can take up hundreds or thousands.<\/p>\n<p>However, clock speeds are only one aspect of a CPU's speed.<\/p>\n<p>Other factors like the number of cores, its cache sizes, and the internal architecture of the CPU also play a key role in overall performance.<\/p>\n<p>One of the most common reasons why a CPU with a higher clock speed may be outperformed by a newer generation processor of a lower frequency is because of architectural improvements that result in an IPC gain.

It incurs a lower power or thermal cost and therefore lets you boost a single core to much higher frequencies than you could increase the frequency of all cores.<\/p>\n<p>This is also why advertised boost clock speeds (e.g. 5.3GHz+) can often only be reached on a single core and not the entire CPU's package. Thermal limits (i.e., heat that your cooler is capable of dissipating effectively) are the reason why such automatic boost clocks can often only be reached in bursts and are only held for very short periods of time.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Boost_Clock_vs_Overclock\"><\/span>Boost Clock vs Overclock<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Although Boost Clocks in a CPU is a form of (automatic) overclocking, it is not to be confused with manually Overclocking your CPU, which refers to <em>manually<\/em> increasing these multipliers (and voltage) in intervals to find the CPU's maximum stable frequency.

It produces disproportionately more heat and draws exponentially more power with every push to the CPU clock. The farther you stretch it, the more pronounced the power draw and heat becomes. This is why extreme overclockers typically work with liquid nitrogen to hit world record clock speeds without losing stability.<\/p>\n<p>That said, you CAN manually overclock your CPU to run at or, even above, its boost clock when in use. As long as your <a href=\"https:\/\/g100.us\/air-vs-aio-coolers\/\">CPU cooler<\/a> and case airflow are robust enough to dissipate the generated heat.<\/p>\n<p>Pushing your CPU too far can shorten its lifespan. The thermal paste dries out more quickly, and errors within the core silicon become more regular, the hotter the CPU is.<\/p>\n<p>Then there are thermals: your CPU Cooler is a huge bottleneck that has to be factored in. A cooler heatsink can absorb and dissipate a lot more heat than a hot heatsink. So it's possible to reach higher boost clocks if your CPU was clocked low and produced only a little heat before it is boosted - even for just a couple of seconds. But if a CPU cooler is already pushed to its limit at or near its base clock, it won't have much headroom to boost to desired\/advertised levels.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Factors_Impact_Boost_Clock_Speeds\"><\/span>What Factors Impact Boost Clock Speeds?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>How long the CPU can hold its boost clock frequency, as well as how high the frequency can go, depends on the following factors:<\/p>\n<h3><span class=\"ez-toc-section\" id=\"1_Its_inherent_hardware_capabilities_defined_by_the_manufacturer\"><\/span>1.
