Computers used for gaming include a graphics card (GPU) separate from the CPU (central processing unit). How many calculations do you think your graphics card performs every second while running video games with incredibly realistic graphics? Maybe 100 million calculations a second?

Well, 100 million calculations a second is what was required to run a Mario 64 from 1996. Today we need more power. Maybe 100 billion calculations a second? Well, then you would have a computer that could run Minecraft back in 2011.

In order to run the most realistic video games in 2024, such as Cyberpunk 2077, you would need a graphics card that can perform around 36 trillion calculations a second. This is an incredibly large number, so let’s take a second to try to conceptualize it.

Imagine doing a long multiplication problem, such as a seven-digit number times an 8-digit number, once every second. Now let’s say that everyone on our planet does a similar type of calculation, but with different numbers. To reach the equivalent computational power of our graphics card and its 36 trillion calculations a second, we would need about 4,400 Earths filled with people, all working at the same time and completing one calculation each every second. It’s rather mind boggling to think that one device can manage all those calculations.

Now, let’s move from gaming to the world of Artificial Intelligence which were trained using a large number of GPUs. A flagship Nvidia A100 GPU can perform 5 quadrillion calculations per second (a 5 followed by 15 zeros). In 2024, a medium sized AI will be trained using at least 8 GPUs. Very large models can use hundreds or even thousands of GPUs. In 2024 Elon Musk showcased Tesla’s ambitious new AI training supercluster named Cortex in Austin, Texas. The supercluster is made up of an array of 100,000 GPUs, each one performing 5 quadrillion calculations a second, using as much power as a small city.

Possible Preaching Angle:

1) Omniscience of God – While artificial intelligence has made remarkable strides, it cannot compare to God’s omniscience which far surpasses any human creation. He sees all, knows all, and understands the intricacies of every life. The hairs of every head are numbered (Matt. 10:30), the length of our lives is known (Psa. 139:16), and not even the smallest bird falling to the ground escapes his attention (Matt. 10:29); 2) Knowledge of God; Wisdom of God – AI can only process events after the fact, and perhaps anticipate some possible actions. But God knows all things, past, present, and things to come before they even happen (Isa. 46:10)

Editor’s Note: For an excellent statement of the omniscience of God, see A. W. Tozer, The Knowledge of the Holy, (Harper, 2009) p. 62 “He knows instantly and with a fullness of perfection that includes every possible item of knowledge concerning everything that exists or could have existed anywhere in the universe at any time in the past or that may exist in the centuries or ages yet unborn….”
