When will one TeraFlOPS cost $1?

The performance capabilities of computers (e.g. CPUs, GPUs and Supercomputers) are expressed in floating point operations per second (FLOPS), a standard rate for indicating the number of floating-point arithmetic calculations systems can perform per second.

Currently, the NVIDIA TITAN V GPU, has one of the lowest theoretical performance cost at $27.27 TFLOPS ( FLOPS), with a price of $3000 and a theoretical peak performance of 110 Tensor TFLOPS.

However, theoretical peak performance relies on the accelerating parts, and generally does not involve other hardware such as memory, network or I/O devices. An analysis of GPU performance, finds that theoretical predictions of maximum theoretical performance of three different GPUs to be higher by around 30% when compared to experimental results. Similar work on CPUs has found discrepancies between actual and theoretical maximum performance of generally within a factor of 10.

To take this into account, we shall here assume that theoretical cost figures (such as reported by hardware manufacturers are 10 times too low), setting current costs at $272.70 per TFLOPS. Getting to below $1 would therefore amount to a orders of magnitude reduction in cost per TFLOPS.

Interestingly, according to some estimates, a reduction in computing costs of roughly 2-3 orders of magnitude could place the cost of computation at the brain's communication performance in the range of human wages (around a couple hundred dollars per hour).

When will a TFLOPS cost less than $1?

This question resolves positively if a reputable source reports a TFLOPS for Tensor, or single/double precision performance to cost less than $1 using reliable performance measurement techniques. The usual theoretical price estimates given by manufacturers will be multiplied up by a factor of 10 for the sake of this question (hence requiring a $0.1 theoretical cost per TFLOPS for positive resolution).

Metaculus help: Predicting

Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.

The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available. With tachyons you'll even be able to go back in time and backdate your prediction to maximize your points.

The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.

Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.

Community Stats

Metaculus help: Community Stats

Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.

When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
