BY NOW, WE WERE hoping to have official news of Nvidia’s next-generation graphics cards, but it seems we’ll have to wait just a little bit longer. The 4000-series will be based around the new Ada Lovelace GPU, which will reportedly bring a massive speed jump. Some reports talk of a doubling in performance, which seems, frankly, wishful. Figures of between 66 and 80 percent sound more achievable, while still being remarkable enough.
