Foreign media measured the new 27-inch iMac, the heat dissipation performance is better than the previous generation

Some time ago, Apple officially released the 2020 27-inch iMac. The new iMac is equipped with a 10-generation Core processor customized by Intel for Apple. Compared with the previous generation, the performance has been significantly improved. The question is, can the heat dissipation of the iMac suppress the highest version of the tenth generation i9 processor?

In response to this problem, the foreign media Apple Insider tested this, and the tested model was configured with Intel’s tenth generation i9 processor, 8GB RAM and AMD Raden 550XT discrete graphics. In the Geekbench CPU test, the new 27-inch iMac scored 1256 for single-core and 7958 for more drinks. In contrast, the lowest test score for the same model is 1141 for single-core and 5635 for multi-core. The gap is not small.

In the rendering test of Cinebench R20, the new iMac scored 5424, which is a certain gap compared with the general i9-10900 desktop version. It can be seen that the temperature wall has been triggered, but the performance is still higher than the previous generation. less. At the same time, Apple Insider also gave the test environment, the ambient temperature is 21 ℃, all tests are performed continuously, and there is no interval for cooling the hardware.

During the test, the iMac can maintain zero-noise operation for a period of time. After the temperature rises to 38°C, the fan starts to run, and the processor frequency is maintained at about 4.3GHz, which is barely enough for general high-load work. Up. Moreover, there has been no problem of continued frequency reduction in the subsequent tests. It can basically guarantee a good performance under high load conditions. Although it is not comparable to the iMac Pro at all, it is already a good result.
