What's the difference between Sony's PlayStation Vita and the PS3? About 256MB of RAM, apparently. In a recent interview with Eurogamer, Sony Worldwide Studios president Shuhei Yoshida confirmed that the forthcoming handheld will boast a full 512MB of RAM (compared to the PS3's 256MB), allowing the Vita to support cross-game voice chat via its Party feature. Yoshida's confirmation effectively debunks earlier rumors that Sony would be halving the Vita's RAM, in order to compete with the 3DS' lower price, though the console does feature comparatively less V-RAM (just 128MB, versus the PS3's 256MB). According to the executive, however, that disparity won't make too much of a difference on the gaming experience, due to changes in the Vita's display resolution. "The resolution on the PS Vita screen is much lower," Yoshida said. "Even though it's four times the resolution of PSP, compared to the console, the amount of data you have to push is much smaller." The proof, of course, is in the pudding, but unfortunately, we probably won't be tasting it for a while.
