These are applications that are responsible for analyzing the performance and behavior of the CPU to know its operating speed and performance, without downloading programs for it. Which at first glance can be counterproductive, since the performance of a processor is maximum the closer the data is and it does not a priori make sense for a web page to be able to measure our CPU.
In reality, these pages load a program in the form of a web application, which is temporarily stored in our RAM and is in fact executed from our PC and not remotely. Then the operating system when we close the browser tab or it will release the memory. This allows us to test the performance of our processor without having to download anything to our PC.
This is also possible due to the fact that benchmarks are very lightweight programs, as some of them have to be run from the CPU cache, and that’s a few megabytes, so it’s a waste of time. install them when we have the possibility to run them directly and in a very short time thanks to the current Internet speeds.
Performance influence
Our computers are multitasking systems that run dozens of different processes and when performing a performance test, it is important that our computer can focus only on this one. This is why we recommend that you close all applications, background processes that you can and do not forget about the various tabs of the browser itself.
What online benchmarks exist?
Below we leave you a list of online benchmarks that you can run from your PC’s browser to measure the performance of the processor you have installed on it, as well as to find out how it compares to the rest of its type and to similar hardware, on the same or similar computer configurations.
CPU speed test
The first option available is the one we recommend the least, because the CPU speed test requires the installation of Adobe Flash and it ends up becoming a waste of resources and the security problems associated with it. We also have a version for Java, but since Oracle bought Sun and made Java pay, it loses points.
And how is the reference? Well, very limited, because it only allows us to measure the CPU clock speed if we press the option to start the Performance Test. This is not why it is completely useless, since it allows us to know the clock speed in real time. The problem, as we have already mentioned, lies in the use of Java and Flash for the online version of the benchmark, which, in addition to the problems we have mentioned before, are also a load on the processor. In conclusion, this is not the best way to measure your PC’s CPU performance.
CPU Expert, cross-platform and complete
Second, we have an online benchmark that allows us to measure CPU performance more comprehensively than the previous one and is based on running a decryption algorithm to check CPU power. CPU Expert is a test that gradually increases its workload, causing it to run more and more processes. Before launching it, the web page asks us for our processor model and what we want the benchmark for, which shows us that this online benchmark is not able to detect what the benchmark will be on. To do.
This is a benchmark completely independent of the ISA, so it will not only allow us to measure the performance of x86 cores for PCs from Intel and AMD; but also ARM processors and even RISC-V. At the end of the test, it will inform us of the score obtained and at what position within the ranking within the online benchmark itself.
Expert CPU stress test
In addition to the standard test, CPU Expert allows us to perform a stress test on the processor, which is much more complete than the previous one, since we can directly configure two different parameters. On the one hand, we can assign the number of processes that we are going to load the processor, which will allow us to measure the performance of the CPU with one core or with several. As for the Power parameter, it helps us mark the working time allocated to each core as a percentage of time for each core. The workload is calculated by multiplying the workload by the number of threads.
SilverBench, online reference for multihilo
The third online benchmark is SilverBench, but it helps us to measure the multithreading capacity, which uses a JavaScript script for this and offers us three different performance possibilities: the normal benchmark, an extreme test and a stress test. SilverBench is a benchmark that runs the Photon Mapping algorithm, a variant of Ray Tracing, but it never does this using the GPU.
The standard test at the end will only give us a performance figure once executed, on the other hand the extreme test will take 10 times more, since in said mode the benchmark renders an image which is an order of magnitude larger and, therefore, with higher workload, it will maintain CPU speed much longer. As for the stress test, it will help us measure the stability of our processor, in this case it will give us information on the time it takes to render each frame under Photon Mapping.
Unlike the previous case, where different execution threads are measured against each other with no apparent relationship, with this benchmark we can measure the performance of the cores when they work together on a common task. The only thing missing is being able to adjust the number of threads for the algorithm to more than 4, especially for much larger CPUs.
