HDR vs SDR HDR (High Dynamic Range) is the newer and more advanced version of display technology that shows more colorful and brighter pictures on displays that support it. It is much superior to its predecessor SDR. Videos in HDR format use 10-bits for storing color information and use different color transfer functions compared to… Read More »
Ram Timings are an important part of the ram specifications. They look like a series of number like this: 22-22-22-52. These timing numbers indicate how fast or slow the ram would perform in conjunction with the cpu. Higher timings indicate that the ram takes more time to internal operations, and is slower. Lower timings mean… Read More »
RAM Speed (read and write) is crucial to the overall performance of the system. Having a fast cpu but slow ram can slow down a system in demanding work-loads like video editing and gaming. Ram size and speed are different factors. Ram size determines how much data can be stored in the system, whereas the… Read More »
