I actually kinda like the idea. Segmentation has its negatives for sure, but speaking for myself, if I were buying a 4080 for 1440p/165Hz gaming (I'm not but a man can dream) and I had a choice between a hypothetical €850 16GB version and a €750 version with 12GB, I'd buy the cheaper one. In spite of Alien's best efforts to convince me

12GB is enough for 1440p gaming. Of course, why would anyone buy a 4080 for 1440p gaming? Because they prefer gaming at 165 FPS with one tiny setting turned down and saving €100 than playing with 90 FPS at 4k with all the settings at their max (when visually it's borderline impossible to tell the difference) and pay an extra €100 for it. Segmentation is just choice. Again it has its drawbacks, but it is still just choice.
