As we all know, this year’s Galaxy Note20 Ultra is sold with two CPU options in different markets. While most of the market is distributed Galaxy Note20 Ultra uses the Exynos 990 chip, users in some countries such as China, the US and South Korea are allowed to use the Galaxy Note20 Ultra with a powerful Snapdragon 865+ chip. most from Qualcomm.
From past to present, prejudices about Samsung’s Exynos chip have existed. Over the past few years, Exynos chips have consistently outperformed Snapdragon chips at the same time of launch. This year is no exception, the Exynos 990 chip is rated as not much more powerful than last year’s Exynos 980, while the Snapdragon 865+ is far ahead of competitors in terms of performance.
Another difference between the two Galaxy Note20 Ultra versions comes from the cooling system. With Galaxy Note20 Ultra using Exynos chipset, Samsung integrated for this version a vapor chamber cooling system with vapor chamber cooling, while for the Snapdragon 865+ version, the machine is equipped with heat-conducting layers. graphite-based cooling.
Considering the impact of the cooling system on the CPU performance of the two versions of the Galaxy Note20 Ultra, YouTube channel JerryRigEverything recently performed tests and measures the performance before and after exchanging. The cooling system of the two versions of Galaxy Note20 Ultra. The results showed a surprise: The cooling system did not affect the performance of both machines too much.

Specifically, JerryRigEverything conducted performance tests of both Note20 Ultra versions with Geekbench 5 performance scoring software, each 8 times. The results are not surprising when the Exynos 990 performed about 20% worse than the Snapdragon 865+ in both single-core and multi-core tasks.
After 8 performance tests, Galaxy Note20 Ultra Exynos always gives about 20% worse performance than the Snapdragon version.
After “abdominal surgery” and exchanging two cooling systems for each other, that is now the Exynos 990 will use carbon thermal conductors, while the Snapdragon 865+ will use the vapor chamber cooling system, the results for The gap between the two versions remains unchanged. However, the performance at this time of both machines has decreased by about 3%, this is attributed to the cooling system is no longer complete as originally.

There is no difference in performance between the two versions. At this point, the performance of both machines has decreased by about 3%.
In the test video of JerryRigEverything, he also discovered an interesting thing is that the Exynos chip “eats” more battery power than the Snapdragon 865+ chip on the Note20 Ultra after many performance tests.

Thus, although Samsung has always claimed no performance difference between the two versions running Exynos and Snapdragon chips, but through the tests of JerryRigEverything, we can once again confirm. The Exynos chip is actually inferior to the Snapdragon in terms of performance, namely the Exynos 990 and Snapdragon 865+ on the Galaxy Note20 Ultra. Not to mention the power consumption factor, the Exynos 990 both delivers poor performance and consumes more power than the Snapdragon 865+.
