I'm getting 447k geekbench constatnly on asus 4090, with latest bios and 100% overclock through GPU tweak III

I have not heard details, but judging from Ngreedia's recent practices, it could be 24h before launch, i.e. October 11 on 13:00 GMT. If earlier, you would notice on YouTube.

When is the review embargo date lifted? Before the availability date?

Every day, notebookcheck sounds more and more like it's trying to copy wccftech. It's really sad. It would be nice if it found its own, more objective voice. I know, somehow, the thousands of trolling messages wcctech gets for every single article, which have nothing to do with the article, must somehow generate revenue, but the world really needs a components level tech site that isn't about "insane" game-focused performance. What made this site special was its objective, consistent reviews of notebooks. It wouldn't be as exciting, but it would be great to find a way to continue that. And it might save you some pain in your very stilted sounding rewrites of press releases and summaries of other site findings that basically just add a bunch of "moreover" and "alsos."
