On December 10, the author wrote an article to share a news with the majority of digital hardware enthusiasts, MSI Japan issued an announcement admitting that the four processor water-cooled radiators were defective and started the recall procedure.
As the saying goes, "blessings are incomparable, disasters are not singular", good news is often difficult to come at the same time, bad news is often one after another, today the author wants to share with you is another bad news of a somewhat similar nature.
However, the protagonist is not MSI, but Acer (ACER), and the severity of the matter is not as serious as some friends' brain supplements, there is a leak that causes the entire accessory to be damaged, but it is just an unreasonable design, there are defects, and the actual effect is not good, so you don't need to panic.
Specifically, it wasn't the Acer CPU liquid cooler that was found to be problematic, but the custom GeForce RTX 4090 graphics card that came on its Predator Orion X console. This graphics card is equipped with a liquid cooling radiator, and the materials and workmanship look very good, but the third-party authoritative test results show that this graphics card is very poor.
So, how bad is its actual heat dissipation?To put it simply, it is not as good as the public version with relatively thin workmanship and materials.
Recently, a well-known overseas Kitguru blogger tested Acer's GeForce RTX 4090 graphics card, and compared it with a number of GeForce RTX 4090 graphics cards from other competitors. I'm not afraid of not knowing the goods, I'm afraid of comparing the goods, what is the effect, a comparison is very intuitive.
The comparison is mainly divided into four dimensions: 1. The highest operating frequency of the graphics card, to a certain extent, represents the performance. 2. The temperature of the GPU. 3. The temperature of the video memory. 4. Noise.
First, let's talk about how often the graphics card runs. Nvidia's official GeForce RTX 4090 runs at a maximum frequency of 2520 MHz (see Figure 2), but this value is conservative, and graphics card manufacturers will increase this value appropriately.
According to measurements, the Acer GeForce RTX 4090 runs at the bottom of the pack at 2644 MHz. This is 36 MHz lower than the second-to-last GIGABYTE RTX 4090 Gaming OC 24GB, 39 MHz lower than the public version, and the highest ranking is the MSI product at 2820 MHz.
In terms of GPU temperature, the Acer GeForce RTX 4090 is the highest, with an overall temperature of 758 degrees, the local maximum temperature is 850 degrees. As a reference comparison, the overall temperature of the public version is 702 degrees, the local maximum temperature is 783 degrees, and the performance is also lower than Acer.
The GIGABYTE RTX 4090 Gaming OC 24GB has an overall temperature of 689 degrees, the local maximum temperature is 810 degrees. The best performer is still MSI's products, with an overall temperature of just over 60 degrees Celsius and a local maximum of less than 76 degrees.
In terms of video memory temperature, the maximum temperature of the Acer GeForce RTX 4090 is 96 degrees, the public version is 84 degrees, which is 12 degrees lower than Acer, the Inno3D RTX 4090 X3 OC 24GB is 70 degrees, and the best performance is the Gigabyte RTX 4090 Gaming OC 24GB, with a maximum memory temperature of only 66 degrees.
The last test item is noise. The Acer GeForce RTX 4090 is 44 dB and the public version is 41 dB, which is 3 dB lower than Acer, the MSI RTX 4090 Suprim Liquid X 24GB is 35 dB, and the best performer is the Asus RTX 4090 Tuf Gaming OC 24GB with a score of 34 dB.
The final conclusion is that although the cooling configuration of Acer's GeForce RTX 4090 graphics card is very luxurious, the actual effect is very unsatisfactory, almost all the evaluation indicators are terrible, and the performance is even lower than the public version, which should not be, it is really embarrassing.
Generally speaking, many small and medium-sized studios will buy a GeForce RTX 4090 graphics card as a productivity tool, which will run for long periods of time under high load, and heat dissipation is very important. Therefore, this GeForce RTX 4090 graphics card from Acer has considerable room for improvement, and I hope that Acer will take it very seriously.
