On the mobile side, the R95900 series has two versions of R95900HS and R95900HX, which are one of the top CPUs in the notebook CPU field at this stage. So what is the difference between these two twin CPUs, as consumers, how should we choose, this article will explore this topic well.
Parameter differences between R95900HX and R95900HS:
R95900HX：
8-core 16 threads, silent frequency 3.3Ghz, design turbo frequency 4.6Ghz, default TDP45W, supported
AMDConfigurableTDP technology, power consumption can be dynamically adjusted between 35W-54W, TSMC 7nm process, three slow 16MB.
R95900HS：
8-core 16-thread, silent frequency 3.0Ghz, design turbo frequency 4.6Ghz, default TDP35W,
TSMC 7nm process, three slow 16MB.
From the parameter point of view, we can clearly see,
The R95900HX is actually a high-frequency and overclockable version of the R95900HS
, its silent frequency of 3.3GHz is 0.3Ghz higher than the R95900HS's 3.1 (3.0) Ghz, as for the default turbo frequency, the two CPUs are exactly the same as 4.6Ghz, but since it ends with "X", R95900HX has a special function - overclocking,
It was also the first CPU on the mobile platform to be overclocked.
(There is also a higher positioning R95980X in the future)
According to the current evaluation data, R95900HX can stabilize the highest turbo frequency at 4.7Ghz, which is 0.1Ghz higher than R95900HS, and the comprehensive performance has been improved.
Performance scores for R95900HX and R95900HS
Geekbench (single-core): 1438 points.
Geekbench (multicore): 7493 points
CinebenchR23 multicore: 13036 points
CinebenchR23 single-core: 1497 points
Geekbench (single-core): 1458 points (101%)
Geekbench (multicore): 7623 points (102%)
CinebenchR23 multicore: 13532 points (103%)
CinebenchR23 single core: 1501 points (101%)
In the base frequency, the performance of the two SOCs is basically the same, R95900HX only has a running score advantage of about 1%-3% with the advantage of the silent frequency, of which there is almost no gap under the performance of the single core, in fact, this is also very normal, after all, the basic turbo frequency of the two CPUs is 4.6Ghz, the performance is the same, and it can not open up any gap in the performance of the single core. However, with the frequency advantage under the silent frequency, R95900HX has an advantage of about 3%, and from this aspect alone, the gap between R95900HX and R95900HS is not very large.
But don't forget, R95900HX can be overclocked, according to the test data, R95900HX in the case of overclocking 0.1Ghz, performance can be increased by about 7%, relatively or more obvious, but heat and power consumption will also be improved.
R95900HX and R95900HS power consumption and heat generation
Test data from AIDA64 single roast/double baking data (from Zhongzheng evaluation)
Single baking: CPU core temperature 88 degrees, power 62W-65W or so.
Double roasting: CPU core temperature 76 degrees, power about 35W.
Single baking: CPU core temperature 95 degrees, power 79-82W or so
Double roasting: CPU core temperature 84 degrees, power 44.91W or so.
Summary: R95900HS is sufficient.
From the above running points and power consumption tests, we can see that R95900HX in the case of obvious power consumption increase, but did not show special advantages in performance, the comprehensive advantage of less than 5%, as for overclocking, although it is a big selling point, but for the notebook that was originally anxious for heat dissipation, it is unwise to toss overclock, too high temperature even if the CPU can be endured, whether other components can adhere to it is two words.
Personally, if the R95900HS comprehensive cost performance and better performance in other configurations are comparable, it is recommended that everyone choose, or that sentence, buy a notebook do not blindly pursue peak performance, choose the model that takes into account the performance, power consumption, heat and other aspects is the best.
Hope that can help you
