Next, there will be a large number of notebooks with Intel's 12th generation Core processors on the market, how does the new version perform? Is it worth the wait?
Now, Lenovo has released the test data of the new machine equipped with the 12th generation Core processor, giving you a quick look at the performance of the new machine. The test model is the engineering machine of a new machine of Xiaoxin, the test results are for reference only, and the final retail version shall prevail.
We know that the 12th generation of Core Mobile Edition mainly has three versions, look at the letters at the end can be distinguished, simply divided into U, P and H three gears, the performance is also stronger.
This article tests the Core i5-1240P, which has the same 12 cores and 16 threads as the i7-1260P, of which 4 are performance cores and 8 are energy efficiency cores. The difference is that the kernel scale and L3 cache are slightly smaller, and there is also a certain difference in frequency.
In terms of CPU theoretical performance, the Cinebench R20 was used for running score testing. It can be seen that compared with the previous generation i5-1155G7, the i5-1240P has a significant performance improvement.
Among them, single-threading has an improvement of about 6% due to the architecture upgrade of P-Core, and the multi-core performance has also improved by about 12% in the case of similar performance release because of the overall energy efficiency optimization.
The Xe core display of the 11th generation Core gave us a relatively big surprise at that time, but the 12th generation Core's core display architecture was not upgraded, it is still the Xe-LP architecture, and the maximum is only 96 sets of execution units.
However, due to the 12th generation Core supporting DDR5 and LPDDR5 memory, the higher frequency brings higher bandwidth, so it can be seen that the performance of the core display is greatly improved compared to the original with DDR4-3200 memory.
Such an improvement is reflected in the actual game is a more obvious increase in the number of frames, "League of Legends" in 1080p resolution, the average number of frames of the special effects full open can reach about 120fps, much higher than the previous generation.
In the slightly older AAA game "GTA V", under the low special effects of 1920x1200 resolution, the average frame number increased from about 30fps to 50fps, which basically changed from basic playable to smooth and playable, and the improvement was obvious.
The bigger surprise comes from the practical application, Lenovo uses the measured Pr for video editing and export testing, a 4K50 10-bit 4:2:2 footage is simply edited and rendered after adding effects, the advantage of memory bandwidth is more obvious here, the rendering time of i5-1240P is shorter than a full minute, and the export is faster.
That is to say, on the new small and new thin and light book, video editing will be more efficient and easier than before, which is also due to the fact that the i5-1240P has two complete media acceleration engines.
As can be seen from the above tests, the new generation of Core i5 can be said to have a comprehensive improvement, and it can be more clearly reflected in our commonly used creative applications and games.
In the first half of this year, Lenovo will launch at least 20 new products, of which as many as 8 are small new notebooks and YOGA notebooks, all of which use 12th-generation Core processors. Next, Lenovo will release more revelations, including the endurance performance that everyone cares about, etc., we will wait and see.
