Future of desktop cpus

[Vaskozlov]

I am a second year student of “Project School”, which specializes in technical subjects. Currently, I am working at my school project, which in connected with compilers and programming languages.

Predictably I have some relevant questions and I would appreciate it if you could possibly answer them as I am sure that specialists from your company could give me their valuable advice.

So I am interested whether a few small cores ensure better performance in comparison with a single powerful one. I know that 4 e-cores are about 30% faster than p-core and take about the same surface area. After I estimated the surface, using the photo of the chip, I found out, that e-cores cluster is 28% bigger than p-core. So cpu space is used almost equally effectively in terms of computing power, but e-cores cluster is supposed to consume less energy.
Taking it into account I would also like to know
• Which core has a greater performance for the same amount of surface area.
• What the power consumption difference between e-cores cluster and p-core is.
• Whether p-cores will be replaced by e-cores in personal computers or at least in servers in the near future.
• Whether ARM based cpus are more energy efficient because x86 cpu is to translate cisc instructions into risc ones.
• Whether it could be more beneficial to rely on a compiler rather on cpu in terms of instructions reordering.

Thank you for your attention I am looking forward to your answers.

Hello, @Vaskozlov. 

Thank you for posting on the Intel® communities.  

Please specify the model or family of the processors you are requesting this information, as this will vary depending on the model.

Thank you for your reply.

I would like to know this information about the 13the generation of Intel processors.

Hello, @Vaskozlov. 

Thank you for the information provided. 

Let me do some research about all your questions, as soon as I have updates, I will post them here.

Hello, @Vaskozlov. 

Thank you for your time. 

Please find the answers to your questions below: 

• Which core has a greater performance for the same amount of surface area? 

• What is the power consumption difference between the e-cores cluster and p-core is. 

For this information, you can find this information in the technical processor specifications article 13th Generation Intel® Core™ Processor Family, in the section of Power management you can check information about cores and so on. 

• Whether p-cores will be replaced by e-cores in personal computers or at least in servers in the near future. 

For new release information, you can check the Intel newsroom about inquiries like this one or about the future. 

• Whether ARM based CPUs are more energy efficient because x86 CPU is to translate cisc instructions into risc ones. 

We don't handle information about third-party products. If you want to compare CPU performance, we recommend you to check with ARM for its processor information, and we can provide information about our processors, so you can check their performance based on the intention of how you are going to use the system. 

• Whether it could be more beneficial to rely on a compiler rather on CPU in terms of instructions reordering. 

In case you are trying to develop a project and require more information, you can find this information in the developer zone. How to Apply for an Intel® Resource and Documentation Center (RDC) and/or Intel® Developer Zone (Intel® DevZone) Account
