As one of the processors with the best gaming performance today, AMD Ryzen 7 7800X3D is definitely worthy of the word "excellent" in terms of gaming performance. However, there are always many people who want to ask what should be paired with this gaming processor. What kind of radiator is suitable ? In this episode, I will share with you how much difference there is in the performance of AMD Ryzen 7 7800X3D when paired with different types of radiators. Without further ado, let’s get to today’s main feature. 7800X3D is an 8-core 16 The threaded processor has a default nominal TDP of only 120W when paired with TSMC's 5nm process technology. However, due to the design of the Zen architecture, the 7800X3D, which only has an 8-core processor, lacks a CCX core and uses a 3D V -Cache cache stacking technology makes the heat accumulation phenomenon generated by this processor under normal heat dissipation much larger than other models . In order to verify what type of radiator this specially designed processor is suitable for, this time I We also prepared 6 types of radiators for testing , including 360mm water-cooled representative EK-Nucleus AIO CR360 Lux D-RGB 240mm water-cooled representative Cougar Cougar's Poseidon T5 240 12cm, twin-tower air-cooled representative
12cm, twin-tower air-cooled representative Thermalright Li Min's PA120 4 heat pipe single tower air-cooling represents ProArtist, Yajun G3A 12cm downward pressure air-cooling represents DeepCool, Kyushu Fengshen AN600 , and AMD's original air-cooled Wraith Prism that finally appeared in the Ryzen 3000 series. Due to the limited testing time and production cycle There are also some radiator categories that are not included in this comparison , such as 280mm water-cooled, 14cm double tower and even the flagship 6 heat pipe single tower double fan. I would like to apologize to you first , but after watching this program, you will most likely feel the same. There seems to be no problem without these categories. Next, in order to facilitate your understanding and avoid cognitive confusion, the subsequent tests will not be called the "style" of the radiator but will be classified by the "category" of the radiator. So Next, we will start the test and comparison. First, I will list the platform hardware for this test for your reference. In addition, taking into account the test variables, this test has also been changed from Cinebench R23 used on i7-14700K in the previous issue to a longer test time. Cinebench 2024, which is longer and has fewer variables, also intercepts the average value after 10 consecutive tests. This time, the full speed mode and the unified low noise mode are directly compared together for your reference. After 10 consecutive Cinebench 2024 multi-core runs, After scoring, the difference between the best performance of 1084 points and the worst performance of 1064 points is only less than 2%. Even the difference between the six radiators at full speed and unified low speed mode is less than 1%, which can be regarded as the error range. Switch to frequency. It is not difficult to find out the reason in terms of performance. Three of the radiator categories have achieved a full-core 4.7GHz result . Although the other three models have experienced frequency reduction , the amplitude of the frequency reduction is only up to 0.1GHz, and from time to time it still remains. When it can reach the full-core 4.7GHz , the final performance gap is also very small , and each of these six radiator categories maintains almost the same frequency performance at full speed and unified low-noise mode. Next, let’s take a look at the temperature performance. The good thing is naturally the 360mm water-cooling , but the difference between it and the worst-performing 12cm down-pressure air-cooling and AMD original air-cooling is only 7°C at full speed or unified low-noise mode. You must know that this is close to full load. During the performance test , the specifications of the radiators are very different. The temperature difference of only 7°C is obviously unrealistic. This shows that the main reason is the heat accumulation phenomenon of the 7800X3D , or it can be said that the heat dissipation of the top cover of the processor cannot keep up. The heat dissipation performance of the radiator itself results in the final power consumption performance during testing. All tests were stable between 81 and 85W. Leaving aside the actual power consumption caused by different types of radiators, it can basically be judged that the 7800X3D is used for similar tasks. These 6 radiator categories are basically competent in the full-core rendering scene of Cinebench 2024. Of course, 2 of them , namely AMD’s original radiator and the 12cm down-pressure air cooling, will appear to be particularly difficult, but the final performance impact is actually very small. So it is barely passable. However, the above test is limited to the test results of the 7800X3D in my hand, plus the test ambient room temperature, matching chassis air duct, etc. There are still some differences and variables between your actual use , so if you use this type of For fully loaded rendering scenes, I personally think that if the chassis air duct is not too bad, you can at least use a single tower air cooling with 4 heat pipes. However, if it is in some small chassis or the air duct performance is not ideal, then it is still recommended. Using 240mm water cooling or above will save you some worry , but this is based on the usage scenario of "full core and full load". In fact, I believe that most people choose 7800X3D because of its excellent gaming performance , so the next step is to talk to you. Sharing performance test comparisons under multiple games. Before starting the actual game test, I also ran 3DMark CPU Profile to see the test results of single-thread and multi-thread. Finally, I can see that the difference in single-thread performance is only 0.5% , while the maximum thread performance difference is only 0.5%. The difference in performance is only 1%. Although there seems to be no difference in the theoretical performance test , it is best to compare with actual game measurements. In the end, I chose 4 games with different occupancy performance for testing. Of course, some games with higher occupancy such as " Games like Cities: Skylines 2 are not in my game library , so there is currently no way to test them for your reference. However, I will also promise that this part of the test will be continuously optimized in the future to provide more reference value. The test environment uses The unified low-noise mode is more suitable for daily use and is tested at 1080p resolution (image quality settings vary for individual games). First, let’s take a look at the other five radiators in “CS2” except for the 12cm down-pressure air cooling. All categories have almost the same performance and frequency performance. It can be seen that the 12cm double tower air-cooling has the best performance. The heat pipe single tower has begun to show a certain degree of frequency decline. In terms of temperature performance, the best 360mm water-cooling and the worst performance are compared. The temperature difference between the two types of AMD original air-cooled radiators is about 15°C. However, the temperature gap widened in the game test, which once again proves that it is the heat accumulation of the processor that prevents the full-load heat dissipation performance from being fully exerted. It is the best game in the X3D series. "DOTA 2" is the same as "CS2", only the 12cm downward pressure air cooling lags behind in performance. The difference in frequency performance is smaller. The temperature difference between the best and the weakest is smaller. It has also been reduced to about 10°C. It seems that "DOTA 2", which is more cache-hungry, will have relatively less demand for radiator performance. Then "PUBG", which focuses on memory performance, is more interesting here. In the upper part of the situation , the performance of the combination of 360mm water cooling, 240mm water cooling and 12cm double tower air cooling is relatively consistent, while in the lower part, the performance of the combination of 4 heat pipe single tower, 12cm downward pressure type and original air cooling is weaker than that of the upper part. -12 FPS or so , which is about a 3% difference in frame rate. Compared to the previous two games, the gap in frequency and temperature performance is smaller. Basically, there is no comparison. Perhaps it is impossible to tell what type of radiator is used to suppress it. In the end, it is more focused on the graphics card. The performance of the stand-alone game "Cyberpunk 2077" is relatively consistent from 4 heat pipe single tower air cooling to 360mm water cooling. The remaining 12cm down-pressure air cooling and original air cooling will have slightly weaker frame rate performance, with a gap of 2%- 3% , and the frequency and temperature gap performance is the smallest among the 4 tested games. I think the gap between frequency and temperature performance of the 6 radiator categories is negligible. Summarizing the test results of these 4 games In terms of game performance, paired with 4 heat pipes and single tower air cooling, it can actually achieve more than 97% of the performance of 7800X3D. Although some games may have slightly weaker performance , this can only be discovered by comparing the best cooling conditions in daily life. In terms of use, I personally don’t think it has much impact. As for the 12cm down-pressure air cooling and the original air cooling, I think it needs to be equipped with certain voltage reduction methods , such as using PBO2 or Hydra software, etc. However, voltage offset settings are not recommended. The reason for the voltage reduction is that the 3D V-cache of the X3D series has certain voltage requirements. If the voltage is too low, this large cache will become unstable , so it does not have a certain ability to toss. I suggest that it is better not to set the voltage offset. After this test result, I also came to a very interesting phenomenon. The Phantom Radiator, which was last introduced in the Ryzen 3000 series, is now used to suppress the 7800X3D. It can actually perform beyond my expectations. I seriously feel that If AMD or the corresponding foundry can further optimize and launch a new generation of models to replace the Phantom Mirror, it should not be difficult to cope with the current 7800X3D. It is a pity that this Phantom Mirror has become the last song of the Ryzen 3000 series. I don’t know what AMD will do in the future. There will not be a "most popular original radiator" to replace the Ghost Lingjing. For the 7800X3D, it actually does not need a particularly powerful radiator category to suppress it. It is just because of its special design that no matter what kind of heat dissipation is used. The difference between the processors is very small or even no difference , which leads many people to mistakenly believe that the 7800X3D must be water-cooled. In addition, compared to the i7-14700K in the previous issue, more people generally use the 7800X3D exclusively for playing games. Therefore , using air cooling will not cause too much heat dissipation anxiety. For those friends who are anxious about the standby temperature, I suggest that it is better to let yourselves go. There are still many beautiful things in life waiting for us to discover. The above is this article Related content about what kind of radiator should be used with AMD Ryzen 7 7800X3D.
