It's about time for a dangerous 5-year-old PC and the latest 7th generation Core-equipped PC to fill the gap
This time, I used an A4 notebook PC "LAVIE Note Standard NS550/FA" from NEC Personal Computer, equipped with the 7th generation Core.
My name is Jisa Trippei. Intel's latest CPU, the 7th generation Core (development codename: Kaby Lake), announced at the end of August this year, has passed the consumer electronics show "IFA" in September, and each company is steadily installing PCs for the year-end sales season. We are putting it on the market. Five years have passed since the second-generation Core (development codename: Sandy Bridge), which sparked the popularity of mobile notebook PCs with Ultrabooks. Isn't there a lot of people who are thinking about buying a new pc soon? So, this time, I compared the performance of the 7th generation Core-equipped PC that was just released and the old PC, so I hope it will be a reference when you buy a new one.
The 7th generation Core-equipped PC prepared this time is the NEC personal computer "LAVIE Note Standard NS550/FA". Core i5-7200U (2 cores/4 threads), 15.6 inch full HD liquid crystal A4 notebook PC with 4 GB memory and 1 TB HDD. It's a modern standard line with a BD drive.
As a comparison PC, we prepared a 2nd generation Core i5-2467M (2 cores/4 threads), memory 4GB, 128GB SSD, 13.3 inch LCD (1366 x 768 dots) built 5 years ago. Ultrabooks. And there are two models of mobile notebook PC equipped with Core i5-6200U corresponding to the 6th generation Core (development code name: Skylake), memory 4GB, 128GB SSD, 13.3 inch liquid crystal (2560 × 1440 dots). Actually, I wanted to prepare a PC with a 7th generation Core as a mobile type, but I couldn't make it in time for the verification period. So, this time, I'd like to let you see the pure power competition without worrying about battery life.
Comparing CPU performance with CINEBENCH R15
Standard benchmark software "CINEBENCH R15" that measures CPU performance with 3DCG rendering.
First of all, we compared CINEBENCH R15, which has become a standard CPU benchmark. It will be a power showdown between Core i5s across generations.
Results from CINEBENCH R15. The test was performed 3 times, and considering the effect of the processing heat during execution, the highest value measured with as much time as possible is posted.
In a multi-threaded test with a CPU usage rate of 100%, the 7th generation Core-equipped PC increased by about 86% compared to the 2nd generation Core-equipped PC, almost double the difference. No, the flow of time is a scary thing. In addition, it is about 14% higher than the 6th generation Core-equipped PC, but this is probably due to the difference in operating clocks. This is because the CPU part of the 7th generation Core is made with the same process rules as the 6th generation Core, and if the number of cores / threads is the same, there is almost no difference in specifications.
I think that the heat treatment mechanism of the PC itself has some influence, but as far as I was watching the temperature monitor (using "HWiNFO64") during the test, the operating clock was sluggish after applying CINEBENCH R15 just once. I never fell.
In addition, even in the single thread test, PCs with 7th generation Core increased by about 66% compared to PCs with 2nd generation Core, and PCs with 6th generation Core increased by about 14%, showing a solid advantage. showing sex
