The AGA port on the most recent Alienware laptops seem to be capable of supporting (up to?) PCIe Gen 3 x4. The most recent leaks of the RTX 3090 mention PCIe Gen 4. Based on what I’ve read so far, it seems that the connectors should match up (Gen 3 card in a Gen 4 slot and vice versa). However, a Gen 4 card in a Gen 3 slot won’t be fully utilized due to the bandwidth difference. I created this thread because when I first came across the AGA, it sounded like a decent mid-term upgrade idea, but reading up about the differences in the new generation gave me pause. Given that I’m getting a laptop in the tail end of the RTX 20XX generation and the growing number of places Gen 4 is going to show up, I’m starting to have some second thoughts about this upgrade path and feel like (assuming there isn’t a catastrophic failure or theft), I should just save up for a computer with whatever comes after the RTX 30XX lineup. Thoughts?
