How to Conduct an Accurate Comparison of CPUs

Your computer's brain, the central processor unit (CPU), requires a significant amount of power. Although comparing CPUs is difficult, you can do it correctly if you know which metrics to look for and use the finest resources.

Time of Day Is Not Everything

The processor specs that are most widely advertised are clock speed and core count. A CPU's clock speed is commonly expressed in hertz, such as 3.14GHz, although the number of cores is typically touted as dual, quad, hexa, or octa. But what distinguishes a superior CPU from another given these two specifications?

It was straightforward for a while: faster speeds were correlated with greater clock speeds and more cores. The performance of current CPUs is determined by various different components, therefore clock rates and core counts are not as important as they formerly were.

It all comes down to how much processing power a CPU has when all of its parts cooperate during a single clock cycle. Even though CPU A has a faster clock speed, CPU B can be the superior processor if completing Task X requires two clock cycles on CPU A and just one on CPU B.

Additionally, you should not use clock speeds and core counts as the exclusive means of comparison. Comparing clock speeds between CPUs in the same family with the same number of cores is useful, but it is not always useful in other situations.

When comparing CPUs, clock speed and number of cores have little bearing on whether the comparison is between Intel Core i3 vs. Core i5 vs. Core i7 or Intel Core i5 vs. Core i7 vs. Core i9. Furthermore, comparing clock speed alone will not reveal much whether you are contrasting AMD vs. Intel or an AMD A10 vs. AMD A8 vs. AMD FX.

In case two processors belong to the same family, clock speed serves as a valuable comparison tool. For instance, even if the specifications of the Intel Core i5 12400 and 12600 processors are comparable, their clock rates are significantly different.

Verify Single-Threaded Efficiency

Even if you purchase a CPU with four cores, there is a dirty little secret in the computer industry that you may not use all four of them when running software. The majority of software developed today is still single-threaded, meaning it operates as a single process that can only use one core.

Therefore, you will not be able to use all four cores' performance for that program, even if you have four cores. Because of this, you should always evaluate a processor's single-threaded (or single-core) performance before purchasing one.

As not all businesses formally provide such information, you will have to rely on data from unaffiliated sources, such as Passmark. Using Passmark, you may look up your particular CPU model (found in the options) and contrast it with other well-liked ones available.

Additionally, you can compare models that pique your interest by adding them to your comparison list. The comparison chart includes single-thread performance ratings, so it is easy to figure out which CPU will probably run apps the fastest.

Cache Efficiency Is Essential

The cache is one of a CPU's most undervalued parts. Actually, your computer could be sluggish due to a cache with low specs. Therefore, before making a purchase, you should carefully verify the cache specifications of a processor.

Your CPU utilizes its cache, which is essentially RAM, to store all of the operations it has recently completed. The CPU can get the information from the cache whenever those operations are needed again, saving time by avoiding repeating the work.

A minimum of 64KB of L1 cache should be present in each core of your processor; however, 128KB or more is preferable for resource-intensive tasks like gaming. CPU cache sizes can be compared using Passmark's main comparison table. As long as cache capacity is greater than a decent minimum—like the remarkable 480KB of the CPUs above—it is not as significant as other specifications.

Integrated Visuals Are Important Too

The CPU and graphics card are merged into an APU by AMD and Intel. If you have ever constructed or bought a gaming PC, you may be familiar with the distinctions between an APU, CPU, and GPU; in short, an APU combines these components to save space.

Recent advancements in technology mean that most people's graphics requirements can now typically be met by new processors without the need for a separate graphics card. The performance of these graphics chipsets varies as well based on the processor. Once more, comparing AMD to Intel is not possible, and even comparing products from the same family can be perplexing.

As an illustration, Intel offers graphics called Intel HD, Intel Iris, and Intel Iris Pro, however not all Iris is superior to HD. AMD's Athlon and FX series, on the other hand, lack graphics components but are more expensive than the APU-focused A-Series; if you want to purchase an Athlon or FX CPU, you will need to purchase a graphics card.

How to Compare CPUs in the Best Way

The combination of these elements makes comparing CPUs challenging. How do you choose which one to buy? The simplest and most effective route is to go to Passmark. One of the greatest websites for a quick and useful CPU comparison is Passmark. This website provides an easy-to-understand explanation of processor differences for non-techies.

Additionally, you are not just able to compare CPUs: Passmark also maintains databases with data on pre-built PCs, hard drives, RAM, and video cards. Effective CPU comparison on Passmark only requires a few easy steps:

• By searching for CPUs, scrolling down, and selecting Compare, you can include them in your list.
• To view your list when you have completed making it, click the weighted scale symbol in the top right corner of the screen.
• Examine your processing units. Clock speed, core count, single thread rating, and L1 cache capacity are the key metrics to consider.

The AnandTech CPU Benchmark Tool might be of interest to you if you are looking for more details than Passmark provides. AnandTech is one of the top independent hardware review sites where you can explore thorough benchmarks and even compare two processors side by side.

It could take some time to research the CPUs you are interested in. Being meticulous is not a bad thing. It will get easier to identify the greatest value CPUs available as your confidence in comparing CPU benchmarks increases.
