Most of the reviews I've seen so far are a bit lukewarm. Performance and bettery is good, but they're barely better than what Intel and AMD offer. They promised 20+ hours battery life, we get around 12-13 which is in line with other chips.
The screenshots in the article are from Dave2D's video which compared gaming laptops to the X Elite. Laptops without a dedicated GPU could outperform it in battery, and are usually cheaper. Not to mention the new generation of chips are reportedly way more efficient. Kind of underwhelming.
