What’s the difference between memory clock and core clock on a GPU?

The core clock is the speed that data moves from the GPU memory to the processor cores. The memory clock dictates how fast data can move across the chip as a whole, including between both memory and cores. To copy a chunk of game code from one end to another demands more time when there are more connections to cross. This means it takes longer for your machine to do just about anything when it’s under pressure and you’re running many tasks at once — because every operation has slightly higher latency waiting for data to finish an extra phase or two of travel on its journey around the GPU before returning with result.
