Generation is the most important factor for single thread performance, then power usage and lastly sku.
You could go for an *HX or *H model from a recent gen for an upgrade or if you're fine with the performance you had you could also get a *U model as those are cheaper, more silent and use less power. It's actually surprising that your laptop wasn't that loud
Also the next intel generation is soon to come with big improvements I think, but it'll probably take time for it to be sold
