Sicom's "G-Master Hydro" series is an attractive BTO PC in both quiet and performance.The price is basically high because both the CPU and the video card are water-cooled specifications, but the "G-Master Hydro Z690/D4" is reduced by adopting DDR4 memory.For this reason, it is a relatively easy -to -purchase model among the 12 -generation Intel Core processor (hereinafter referred to as the 12th generation Core), which tends to be expensive.
Of course, if you are looking for the highest performance, you will not be able to compromise and choose a DDR5 memory recruitment model.However, there are not many apps that have a large speed difference due to memory.If you think about cost effects severely, choosing the DDR4 memory "G-Master Hydro Z690/D4" is often more cost-effective.
G-Master Hydro Z690/D4 is a gaming PC equipped with two water-cooled coolers.The direct sales price of the standard configuration is from 367,900 yen (including shipping fee)
Last time, I introduced the hardware aspects, mainly inside the G-Master Hydro Z690/D4, but this time I will check the performance aspects.The models I tried are models with CPUs from the standard configuration, Core i9-12900K, GeForce RTX 3080 for video cards, and 8GB x 4 memory.Other PC parts have been changed slightly, so please check the table below.

The first thing you care about is the performance of the CPU.The 12th generation Core's top "Core i9-12900K" is a very high performance with 16 cores/24 threads, and the fever tends to increase.I checked how much it was cooled with a 240mm radiator water -cooled CPU cooler.
The water -cooled cooler of the CPU is a mechanism that cools the 240mm radiator with two 120mm fans.The radiator is attached to the top of the top, exhausted outside the PC case.
In order to see the maximum performance of the CPU, we used the "Cinebench R23" that can perform full -red operation with CG rendering.In order to perform multi -threaded processing, it is a load test not only for performance but also as a load test to see the fever of CPU.Since the settings were tried as the default, the average performance was about 10 minutes.
The result of Cinebench R23 is 21403pts for Multi Core and 1978PTS for Single Core.
The result of the Multi Core test is 21403pts, which is very excellent compared to the previous generation CPU and the 4th generation Ryzen, which is relatively close to the price range.However, it is a lower value compared to a PC equipped with Core i9-12900K that I made, and considering the potential of the CPU, the score should be better.So I decided to play with the power setting of the CPU.
Before the power settings, it will be necessary to explain the power consumption and the amount of fever of the 12th generation Core generation CPU.Until the 11th generation Intel Core processor, it was described in the indicator of "TDP".Originally, it was an indicator for moving the CPU safely, but in recent desktop PCs and self -made PCs, most of the UEFI settings are based on many motherboards that are operating with power or higher TDP., It was no longer a skeleton.
Therefore, in the 12th generation Core, two types of values were indicated as a new indicator of this TDP.One is "Maximum Turbo Power", which is the maximum value at the time of turbo boost, and the other is "Processor Base Power", which is close to the conventional TDP concept.When a high load is applied to the Core i9-12900K, it is a common operation to operate the maximum Turbo Power's 241W for a certain period of time, and after this time, operate it with 125W of Processor Base Power.。
This number could be changed by the motherboard's "PL1 Power Limit" (Processor Base Power) and "PL2 Power Limit" (Maximum Turbo Power), and by default, it was 125W and 241W.If you raise this number, it will work faster.However, the fever of the CPU naturally increases.In order to check how far it is okay to raise, I first checked using the monitoring software "HWINFO64 Pro" to see what the temperature and power setting of the CPU were in the default setting state.
Check about 5 minutes after the Cinebench R23 Multi Core test starts.The CPU package temperature is as low as 65 degrees, so you can see that you can afford it.
As you can see from the CPU Package Power is about 124.9W, the PL1 setting (125W) is firmly working.The CPU temperature at this time is only 65 degrees.The cooling performance of the water -cooled CPU cooler is still available, and it seems that there is room to endure even if the power setting is higher.So, I set the PL1 to the same 241W as the PL2, changed it to operate with Maximum Turbo Power at all times, and tried Cinebench R23 again.
When PL1 was raised to 241W, Multi Core rose to 25462PTS.Before the change, it was 21403pts, so it would be about 19 %.
However, the CPU temperature at this time is 100 degrees.
Although the score of Multi Core extended to 25462PTS, the CPU temperature was not enough and it was always stuck to 100 degrees.As expected, to cool the Core i9-12900K with PL1 to 241W, the 240mm radiator water-cooled cooler seemed to be heavy.
After repeatedly executing Cinebench R23 with this setting, the average power of the CPU Package Power was stable around 210W.This line seems to be the upper limit, so if you want to achieve the maximum performance within a safe range, it seems good to set the PL1 around 200W.
If the settings such as increasing the rotation speed of a radiator fan or PC case fan separately, the result will change again.However, G-Master Hydro Z690/D4 is also one of the uri specifications.I didn't want to let go of the original character in order to improve the performance, so this time I only changed the PL1 settings.
In addition, it is not the case that the default setting does not have the performance of Core i9-12900K.The test of Cinebench R23 is assumed to be a purpose that keeps a high load for a long time, and it has been well cooled in general use (such as games) where the load changes every moment, so it was easy to bring out the performance.I want you to be careful.
