How computers have evolved shows the simplicity of computers. Quite frankly the reason your computer is more powerful is because we’re processing more units or bits. This means our processing units whether they be CPU, GPU or SPU are now able to process more units or more ones and noughts; having a dramatic effect on the evolution of the computer.

For example an 8bit arcade game is only allowed a top score of zero to 255 because that’s the highest possible number in an 8bit system. Also the game can only have zero to 255 levels and once the maximum level and score has been reached the game cannot go any further. Also consider an 8bit GPU can only have 256 colors, and likewise an 8bit SPU can only produce 256 sound waves. That’s why the old arcade games sounded so flat but they still made a cool retro noise.

Then consider doubling the bits and going to 16bit, we now can have a score and level of 65535. We can now have 65536 colors on the GPU and 65536 sound waves on the SPU. So by adding 1 byte, 8bits, we have significantly increase the number range for the score, levels, colors and sound; improving and evolving the quality of our game.

Then imagine 32bit with near 3billion possible base 2 numbers and 64bit with around 64 quintillion base 2 numbers, you can see just how amazing this really is and how the computer evolves with arithmetic, sound and color.
