Same GPU, different memory
Same GPU, different memory, and that is the entire comparison. The rest of the card does not change: same cooler options, same power delivery, same partner designs. What changes is how long it keeps up as textures grow.
8GB: keeps up until it does not
At 1080p with moderate settings, the 8GB version keeps up. At 1440p with high textures in newer titles, it starts hitting a ceiling the 16GB version does not — the same GPU, stopped by memory rather than by its core. If you plan to keep the card for several years and expect texture packs to keep growing, that ceiling is the thing to think about, not the launch-day frame rate.
16GB: the one that keeps going
High textures at 1440p stay comfortable, and the card ages better as engines ask for more video memory. You are paying for headroom you cannot add later.
Ages better
The 8GB card was named in Korean reports as one of the models hit by price increases, moving from
₩472,500 → ₩706,120
in one tracked listing. That increase narrows the price gap to the 16GB version, which changes the math on the cheaper card.
