No, they're not. X90J is vastly superior. Also, X85J is like 2x the price.
No they don't. The website just mentions 8-core processor and the marketing material just mentions 5nm 5G processor. And Samsung doesn't sell Exynos all over the world, they just switched over to Snapdragon in their home market of South Korea because of backlash over poor Exynos processors. There's no need for Snapdragon in SK for CDMA as Samsung was happily selling Exynos in that market previously.

Also nowhere on their website do Samsung mentions that their Indian variant of QN90A is an inferior ADS panel instead of VA. A few FMs have been burned by that by checking out US reviews.
