Cheaper than the $150 Google TPU Dev Board, and looks like it can do training as well as inference. Training is a slight win (although it's going to be too slow for anything useful really). But it looks like the TPU will outperform this somewhat for inference. The 256 core Jetson (this has 128 cores) could run MobileNet-v2 at between 12 and 20 ms per image (depending on batch size)[1], while the USB TPU adapter takes…

Seems to lose in Mobilenet and win in other benches according to Nvidia's benchmarks. I'll wait for independent testing before I drop $100. https://devblogs.nvidia.com/jetson-nano-ai-computing/

Interesting. I hadn't seen that, but the NVidia numbers on their own products seem credible. I do agree that the flexibility of having real CUDA cores is nice.

Could this be used for an offline voice assistant?

Probably. I've recently compiled Mozilla's Deepspeech for the Nvidia TX1 and it was a painful process. They don't have precompiled binaries for ARM64 + CUDA for Deepspeech, so you have to compile Bazel (v18!), Tensorflow from Mozilla's repo, V1.12, and then deepspeech. If I am remembering correctly, it ran pretty slowly on the TX1. I don't know how well it would run on this new device, or if a lighter weight model is available somewhere.

Horseshit in that bench right off the bat: I have a Google Edge TPU board right in front of me and its perf on SSD300 is 70fps, not 48. That's with the browser demo, which (as far as I can tell) includes realtime encoding of h264 for streaming. Almost twice as much as Jetson, and likely in a much more modest power envelope. NVIDIA is known for dishonesty in their benchmarks. Although TPU is, of course, a quantized pl…

Oh yeah - I never said to trust their benches. Take OEM benches especially vs competitors with the grainiest grains of salt.

When people start getting their hands on them I'll start seeing independent benches, and I think anandtech got their hands on one. Hopefully soon™.

I like the barrel jack for power on the development kit version, I wonder what sort of power requirements it has as that seems to be an issue with the RPiS. On a side note that is a very impressive heatsink too!

What problems are you facing on the pi? The USB power to me is a big win. I already have a ton of cables sitting around.

I am continually amazed that we're able to buy better and cheaper processors that no one could have dreamed about at such power/cost 50 years ago.

I estimate it would take me and you maybe 1 year to learn how to build / assemble most things you find in your house that cost $1000 in a store -- a couch, a rug, even a simple kitchen appliance (the dumb kind).

But a CPU / computer? I could not invent that given 10,000 years, and yet you can buy one for $100. Amazing.

A Pentium 90 was probably fairly common in the mid 90s. Delivered a whopping 0.09 GFLOPS :)

The Power Mac G4 was was briefly a restricted export due to its power (late 90s). This, obviously, gave ultimate childhood bragging rights. https://www.google.co.nz/amp/s/www.wired.com/2002/01/thats-a...

Apple's ad on that was maximum snark. As tanks surround a graphite G4, the announcer deadpans, "Pentium PCs? Well ... they're harmless."

>> Nor does the TPU dev board. Yes it does require you to send your model to Google: https://coral.withgoogle.com/web-compiler/

Oh, interesting! I hadn't seen that.

I suspect it's not going to be like that forever, although I could be wrong. No self respecting AI shop will send them anything production-grade if that's how they want to play it. It'll all be hobbyists and bullshit projects, which, I suspect, is not the clientele they want to attact if it's even a somewhat serious cloud/IoT play. Although this is Google, so it could be canceled in 6 months, too, after the project managers and TLs get their promotions.

Google should license this thing to someone else who can make it in good quantity and sell it really cheap, so others build it into their designs. I'd be pretty excited if that happened.

Heres another potential use - Crypto mining

Not really. It's 472 gigaflops for $100 and not particularly energy efficient. It's useless for bitcoin by a large margin and for Ethereum & co. you can get a used GTX 1070 with 6.5 teraflops of compute for about $250.
