UPDATE (July 29th, 2020):
As per fresh rounds of reports, the Galaxy Note 20 series will feature an improved Exynos 990 processor which will be different from the one we saw in the Galaxy S20 lineup. It is said to deliver performance comparable to the Qualcomm Snapdragon 865 which is something the original Exynos 990 failed to achieve. The report also claims that despite the performance improvements, Samsung will not use a new branding for the chipset.

We know that once Samsung will unveil Galaxy Note 20 and Galaxy Note 20 Ultra, these will be released in variants featuring Qualcomm Snapdragon and Exynos processors depending on the region. Qualcomm-powered variants will likely have the new Snapdragon 865 Plus processor, a new report has painted a disappointing picture for the Exynos model.
Max Weinbach of XDA has tweeted that Samsung will continue using Exynos 990 processor with the Galaxy Note 20 series. His tweet was corroboration for another tipster Ice Universe's tweet where he said, "Damn, Exynos 990 continues". He added that the prediction is based on the fact that the current firmware has no references any new chipset other than the Snapdragon 865+.
Can confirm. I have found no references to any new chip other than Snapdragon 865+ in the firmware's I have on hand.— Max Weinbach (@MaxWinebach) July 11, 2020
The Exynos 990 will be used in the Note 20 and Note 20 Ultra. https://t.co/AGee7eHv8F
Samsung debuted Exynos 990 processor with the release of the Galaxy S20 series earlier this year. It was essentially Samsung's answer to Qualcomm's Snapdragon 865 but as we have seen, there is a huge performance gap between the two chipsets. Many of the Galaxy S20 Ultra users have also complained about issues related to camera performance, battery life, and heating of the unit.
It should be noted that the team has been working on the successor Exynos 992 for quite some time. It is speculated to bring better performance and power efficiency than the predecessor. There were rumors that we might see the chipset make its commercial debut with the Galaxy Note 20 series but it seems like the processor is not ready for the prime time.
