The later 1xxx models are expensive in the aftermarket because a handful of cryptocurrencies are still ROI positive mining on them.
To a lesser extent the 2xxx series is going to be dominated by people wanting to do password cracking. A 2080 Ti will do about 13 billion checks/sec (using NTLM benchmarks), which starts to make financial sense for cracking high complexity passwords from data breaches.
It would be nice if in the 3xxx series they could figure out a way to make it only fast for games and not ML/cracking/crypto.
- esyir 7y agoStrong disagree. We need more democratization of ML capability, not less. Right now the cost of playing around with GANs is pretty prohibitive.
- mike_d 7y agoWell Nivida just released a dev board for $99 that has the GPU chip from a Titan X in it. That is nearing Raspberry Pi levels of "democratized" computing. I don't know much about ML, but my knowledgeable friends say they are saving tons of money moving from GPU farms to GCP TPUs for training.
- close04 7y agoThe only thing it has in common with the (2015) GTX Titan X is the Maxwell architecture for the GPU but with only 128 cores and lower clocks. That would be some magic if Nvidia managed to get the GM200 GPU's power consumption down one order of magnitude from 250W. The Jetson delivers ~2 TFLOPs of single precision performance vs. Titan X's ~6 TFLOPS. Great from such a small board but not quite "same GPU".
- robotbikes 7y agoFrom what I can tell researching it, the 99$ Jetson Nano has around 1/2 teraflop of computing power for 7.5 watts of power. The Jetson TX2 has from 1.5-2 teraflops and costs around 500-600 but there was/is a student Dev kit for 300$, whereas the Titan X has 12 teraflops of computing power.
- close04 7y agoIndeed I posted the numbers for the bigger brother. The Nano is offically slated at 472GFLOPS. The 2015 GTX Titan X (GM200, ~6 TFLOPS, +/- 10% depending on source) is the only one that has something in common with the Jetson - the Maxwell architecture. The one with 10-12TFLOPS is the 2016 Titan X (GP102-400) but that was already using Turing so the comparison would be even more stretched.
- Brave-Steak 7y agoUnfortunately, it seems they're more than happy with the current state of things and they don't particularly care who buys their cards. They can push up the price and the used market will move in lockstep because demand is so high.
- fluffything 7y agoFWIW, I think they do care, because it would be bad for them if gaming on the PC dies, since it drives a lot of innovations in graphics, and nvidia is still at heart a graphics company. However, there is little you can do when the stock of gaming oriented graphic cards disappears on day 0, and re-appears on ebay on day 1 at 4x their recommended price. This products are just very valuable to a lot of people nowadays. Nvidia could ramp up production, but production is not something that you can quickly ramp up or down. There is the fear that crypto will die, and then you end up with a lot of stock that you have to eat at a loss.
- Hamuko 7y ago>FWIW, I think they do care, because it would be bad for them if gaming on the PC dies, since it drives a lot of innovations in graphics, and nvidia is still at heart a graphics company. And because cryptomining is volatile as hell.
- fluffything 7y agoMore than volatile, at some point, using GPUs is just not worth it for cryptomining. Honestly, I think that once they discovered the issue, and decided what to do about it, then the ROI on mining bitcoin was already fading and people were migrating to FPGAs, so maybe they thought "things will get back to normal on its own". Turns out, the number of cryptocurrencies exploded, and many of them are worth mining. Also, every time the ROI on mining one disappears, a new cryptocurrency appears. Maybe they are just still waiting for either this problem to fix itself, by slowly ramping up production, but nothing too steep.
