What Is DRAM in RAM and GPUs? A Basic Definition

DRAM stands for dynamic random access memory and is a type of semiconductor memory seen in RAM and GPUs (aka graphics cards). DRAM memory works by storing bits of data in a capacitor inside an integrated circuit. It requires periodic refreshing (unlike SRAM) to keep data because its capacitors slowly release energy. DRAM is cheaper than…

What Is Nvidia DLSS? A Basic Definition

DLSS stands for deep learning super sampling. It’s a type of video rendering technique that looks to boost framerates by rendering frames at a lower resolution than displayed and using deep learning, a type of AI, to upscale the frames so that they look as sharp as expected at the native resolution. For example, with…
