Can performance be improved indefinitely if the CPU frequency is constant?

Asked by: Stephen 231 views Hardware October 10, 2018

In recent years, Intel's CPU performance has been slower and slower. In the same frequency, there is only a single-digit percentage point, but it has improved. I want to know if the CPU frequency can increase the performance infinitely by updating the architecture; or is the upper limit of the frequency already determines the upper limit of performance? Is the update architecture just let the CPU play more intrinsic performance?

    The architecture is also limited. You can compare the improvement of intel  in these years. This year’s 8th generation  Core suddenly gives strength to performance improvement (in fact, the most important thing is to increase the number and frequency of cores, and the improvement of nanoscale) Before i7 3770k  to i7 4770k  performance improvement is very small (both quad-core 8-wire 3.5-3.9g 22-nanometer, i7 4790k  is the official version of 4770k ), this improvement can be understood as structural improvement According to this idea, the infinite promotion is possible, but I am afraid that the effect is very small…..

    It is said that the architecture can make cpu  more likely to play more intrinsic performance, cpu  The biggest reason for not going to be the instability caused by fever, so increasing the nano-scale will reduce heat, and the lifting structure should also play this role.

    Can’t be infinitely upgraded, because the architecture logic itself has limits, so now, in the face of the disaster, everyone is pre-researching the Ryoko computer.

    In theory, if the frequency is certain, the performance will be improved by upgrading the architecture and process.

    No, the voltage is required. , performance limit is also required

    1. In the computer, the CPU’s [function is calculation], it can be said that the higher the [frequency] of the CPU, the faster the performance (processing speed) of the computer.

         However, the R&D department found that the [frequency] reached a certain level, and the CPU’s [power consumption, heat generation] also increased significantly, which caused the stability to decrease.

    2, in order to control the heat generation and improve the stability, the R&D department has optimized the design: increase the [cache] capacity, increase (can run simultaneously) ) [Multi-threading] capability, process (process, lithography wire width) is more advanced, so that the performance of the CPU has been [further] improved, but the progress of these technologies is relatively slow.

    Frequency affects performance but the impact of new architecture on performance is more important. Now CPU development is mainly based on the update of the architecture to improve performance. If you only increase the frequency, the relative power consumption will increase. >

    The speed of architecture development is faster than the speed of process development. ~~~~ Architecture is developed but not necessarily made into products. I don’t know if I can explain this.~~~ After all, 8 nanometers now. The technology has not yet been mass-produced~~~ still stays at 14 nanometers. According to the theory, it can be infinitely improved, but it must have corresponding manufacturing technology.~~~

    The highest frequency of cpu is limited. This is related to the process of cpu, the materials used, etc., which can exceed the rated value, but the stability is worse. , leakage, power consumption increased abnormally. But the process is limited. When it comes to the size of a semiconductor atom, it is impossible to make progress. Therefore, the limit is coming soon. New materials can also be improved, but they can’t play a big role.

    Answer: The so-called new architecture is the design of the new cpu system. His promotion is also limited. The new method is coming. The harder it is to find.

    Different architectures will differ, but the difference is not great

    The factors affecting CPU performance are ranked in order of influence, roughly: architecture, core number, frequency, cache, power consumption, and process.
