What are the problems and defects in the latest version of win10 1909?

Before we prepare to update the win101909 version, we want to understand the advantages and disadvantages of this version. So as far as the editor knows, although the new version of win10 1909 has been updated and improved with many new features, it still cannot avoid new version bugs. Let’s take a look at what the editor said for the specific content~ I hope it can help you.

What are the bugs in win10 latest version 1909

The suggestion is:

Before Microsoft launches patches optimized for different CPU differentiation, use non-Intel X Series and AMD third-generation Ryzen processor players,

try to avoid upgrading to Windows 10 1909 system.

1. Harm the performance of old hardware

This is not the first time for Microsoft. The new version of the Windows 10 1909 operating system, which will be launched on November 13 (optional installation), applies a new load rotation mechanism

, which allows task processes to more actively choose to run on cores with better physical fitness.

2. Impaired CPU performance

Theoretically, Intel Core X series and AMD third-generation Ryzen can benefit from this new set of threads Benefit from the scheduling algorithm (higher turbo/acceleration frequency).

However, there are more CPUs that do not support this feature (do not have Favored Core), but are also coerced into the new algorithm, resulting in performance damage!

3. Frequent core switching

In 1903 and previous versions of the system, Windows tends to use a random single core to continuously execute single-threaded task loads. .

As shown in the figure above, the entire process of the single-threaded chess test on Core i7-7700K only switched the running core once near the end.

Starting from version 1909, Windows will frequently schedule the core used by the task. During a chess test, the core will usually be switched 3 to 5 times.

4. Performance degradation

When tasks are switched between cores, there will be additional overhead in processor cache and other aspects, which will naturally lead to performance degradation.

As far as the chess test is concerned, the comparison multiple of Core i7-7700K dropped from 8.37 times to 8.29 times.

When choosing to use all 8 threads for testing, there are also very obvious differences between the 1903 and 1909 systems. The new thread scheduling algorithm of 1909 drags down the CPU performance.

5. Damage to CPU performance

CineBench R20 score dropped from 2603 pts to 2534 pts. In other words, the acceleration capabilities of different cores of these old CPUs (including the new 9900KS in fact) are consistent. If you use an algorithm suitable for the new CPU and frequently switch the CPU core where the thread is located, performance will be damaged.

6. Hard disk performance degradation

The PCMark 8 storage test plays back the hard disk read and write load generated by real applications on the hard disk.

Come Measure the impact of SSDs on the time it takes your PC to load common games, productivity software, and design tasks.

The RD500, which uses Toshiba's 96-layer stacked BiCS4 flash memory and the new TC58NC1201GST main control, can achieve a score of 5108 points under the Windows 1903 system, while it will drop to 5105 points on the 1909 system.
