The A-Z Guide to Notebook CPU Ladder Diagram

AMD and intel for cpu ladder

Intel’s mobile version of the processor has jumped from the 8th generation to the 10th generation, and it has made a leap. Due to the large number of models, the speed space notebook CPU ladder diagram has grown taller, and all models have been re-calibrated.

Picture Reading Tips

1. It’s not just the running score of a certain software, it can be regarded as a comprehensive evaluation given by the webmaster. The value does not include the nuclear display performance and AVX-512.

2. There are many difficulties in ranking the tenth-generation Core notebook processors, such as i7-1065G7 (15W) and i5-10210U, which have similar performance. The webmaster compared the two with i7-8565U as a reference.

The analysis process can read the Core 10th generation notebook processor rankings (i7-1065G7 accidentally fell out of the top three)

3. Both evaluation and derivation of CPU ladder are carried out simultaneously.

The webmaster has read a lot of test materials, but a lot of data does not explain the test environment, and the webmaster is cautious about this. As the saying goes, practice is the only criterion for testing truth. However, when measuring processor performance, measured and deduced are equally important. 

Even if it is the same model of the same brand, the measured results under different modes will differ by 30% or more. We can’t put all the 10th generation Core notebooks together for a PK. The derivation can be used not only to check the test data, but also to estimate when the new model lacks evaluation. The two are complementary.

4. You can’t simply copy the processor rankings to pick a notebook and that’s why Notebook CPU ladder diagram is crucial.

Although the i7-1065G7 slightly loses to the i5-10210U, its 10nm process and the better Sunny Cove micro-architecture should be the first choice. Provided other configurations (graphics memory hard disk) and the price are not much different.

Interpretation of The Speed Space Notebook CPU Ladde Diagram Version 5.0

1. The Performance of the Same Type of Processor is Not Exactly the Same.

Mobile processors are different from desktop CPUs. Because heat dissipation is not a big problem for desktop computers. The performance of the same processor in different hosts in CPU laptop can be “basically the same.” But for mobile processors, even if the number and frequency of core threads are the same, their performance can differ by 30% or more on different notebooks. For example, the performance of i7-8550U at 25W power consumption is 50% higher than at 10W.

2. Put the High-End Desktop Processor in the Notebook, the Performance Will Decrease.

Some notebook computers use desktop processors, such as i5-9600K, i7-9700K, etc., because the heat dissipation is too much worse than desktop computers, the general mold cannot withstand the 95W TDP, and the power consumption is limited, which limits the power consumption. The best way is to reduce the turbo frequency, so its performance is a bit worse than the desktop. But this is not reflected in the picture.

3. This Graph is Not Based on the Running Scores, But Takes into Account the Persistence Factor of Turbo Frequency According to the Difference of TDP.

In reality, there are two students. A long-term test scores 90 points but not 100 points. B generally only tests 80 points, but occasionally sometimes tests 100 points. Obviously, A’s results are better.

The CPU test software usually takes a short time and takes few minutes. In fact, this is the performance that the CPU, related to laptop CPU ladder, can achieve in a short time. If the time is a little longer, it will “hit the wall” (temperature wall and power wall), and the performance will drop sharply immediately, similar to the above For example, to measure the performance of a notebook processor based on a short run score, it is prone to misjudgment.

i9-9980HK, 8 cores and 16 threads, 2.4~5GHz, both in terms of turbo frequency and threads, are higher than i7-9700K, why is it ranked below?

Test Score

If only according to the test score, i9-9980HK is definitely higher. However, the test software can only represent the short-term peak value. The power consumption of PL1 has a great impact on the turbo frequency. The time is usually 28 seconds. The actual large-scale game does not take such a short time. The laptop CPU ladder diagram in the extremely fast space should be considered more. “Continuous output capability under high load”, especially the standard pressure models, because they are mainly used in gaming laptops and mobile workstations. For the corresponding workload, the durability of turbo frequency must be considered. The notebook processor is easy to hit the wall and reduce the frequency under high load. If a notebook has excellent heat dissipation and unlocks the power wall to provide a higher TDP, such as reaching 95W, then it is natural to exceed i7-9700K.

However, I can only sort by the official TDP 45W. I can’t imagine that a certain notebook has unlocked the power wall, and then the performance will exceed 9700K. Of course, it’s purely sorted by running points, and it’s no problem to rank i9-9980HK on top.

So, how high the frequency can i9-9980HK maintain under heavy load can be seen through the following example.

Example of High Frequency

HP Shadow Elf 5 Plus (i9-9880H 8 cores 16 threads, 2.3~4.8GHz, with RTX2080 graphics card, dual fans and five heat pipes), under full load, the CPU temperature is up to 93℃, and the power consumption is 60W at this time, which has exceeded the TDP limit. But the frequency can only be maintained at 2.8GHz. It can be seen that there is a huge difference from the maximum core frequency value, and the core frequency basically represents the running score.

For another example, i5-7300HQ and i5-8250U, if you only look at the running score, 8250U is higher than 7300HQ, but due to its TDP limitation, it can only last for 28 seconds at 25W, and only 2.44 milliseconds at 44W (1 second = 1000 Milliseconds), playing games for 28 seconds is obviously not enough. The ordering of the CPU ladder diagram of the speed space notebook takes this factor into account, but note that due to the great differences in the design of different books, some books have simplified heat dissipation design Cost), or because the manufacturer’s conservative power wall is relatively low, this will lead to deviations in the position of the same processor on the ladder diagram.

4. The Performance is Annoying if it Does Not Belong to the Core and Ryzen Architecture.

Some models in the picture are neither Core nor Ryzen, and it is difficult for ordinary users to identify them only by the name. The characteristics of this type of notebook are the “three lows”: low price, low performance, and low power consumption. If you need better performance, you have to choose between Intel’s Core (after the seventh generation) and AMD Ryzen. Intel N does not start with the Core architecture. AMD’s A series and E series are not Ryzen, both of them are difficult brothers. There is no hope for its performance.

5. About Ryzen Mobile

R5-3500U, R7-3750H, etc., the name is 3000 series, but it is not the third generation of Ryzen, but the second generation. The third generation of Ryzen is ZEN2 architecture, not ZEN+.

The second generation Ryzen mobile version (ZEN+ architecture): R5-3500U, R7-3750H, etc.

The second-generation Ruilong desktop version (ZEN+ architecture) regarding CPU laptop: R5-2600, R7-2700, etc.

It is clear from above that it is also the second-generation Ryzen. In terms of the naming of the two, the mobile version starts with 3 and the desktop version starts with 2.

The Ryzen mobile version does not have a high-end model, and the R7-3750H does not wear the R7 halo.

Conclusion

On the desktop version, Ryzen 5’s opponent is i5, and Ryzen 7’s opponent is i7, but on the mobile version, AMD isn’t clear. R7-3750H’s opponent is not intel’s i7, but i5 and even i5-8300H not as good. Although the two frequencies are the same, the TDP of the R7-3750H is only 35W, the i5-8300H is 45W, and the R7-3750H is a ZEN+ architecture. The core efficiency is 5% lower than that of the Core 8th generation. The superposition of these two factors results in its performance only about i5-8300H. About 92% of that, and possibly lower. 

The cTDP of R7-3750H is 12-35W. If it is lower than 30W, it we can assume that it is not worthy to have the H suffix. If it is as low as 12W, it is even more annoying than 3700U. The cTDP of the first-generation Ryzen mobile version R5-2600H can reach 35~54W. It is not clear why AMD reversed the TDP of the second-generation mobile version. It may be the main focus of thin and light games.
