Perhaps a good candidate for mining coins like LivePeer (one of 8-10 actual solid blockchain projects IMO).

Proof-of-work coin mining is a scourge on the environment and the PC component market.

But IIRC still more secure than proof-of-stake systems.

What is the right hardware for ML?

Probably Larabee. Too early and too expensive for its time.

The Japanese PEZY machine looks incredibly interresting. Too bad it is only used in that one super-computer.

Its overall design sits somewhere between a GPU and CPU. Like a GPU, it supports 8-way hyperthreading (GPUs typically support 10. CPUs usually only support 2... maybe 4 for Larabee). Like a GPU, its programmed through an OpenCL-like language (I know you don't like that, but its how it works).

However, the overall layout is very CPU-like as well: a "City" is composed of "Villages", which is composed of multiple "Processing Elements". Each PE is scalar like a normal CPU, although 8-way SMT. So its not like a GPU's SIMD or SIMT architecture in this regards.

It really is an interesting design that toes the line between CPU and GPU.

Transcoding videos is a scourge?!

I mean, maybe you think their choice to deploy as an ERC20 was a bad choice; fine. But they're not adding any additional computation to the environment.

I don't understand how it's possible to think that LivePeer is bad for the environment without thinking the same thing about, for example, Elastic Transcoder. Your comment reads like a non-sequitur to me.

it pushed computing/cooling/energy performance forward and it's not bad for the environment.

>Iceland, which is another hot spot for Bitcoin miners, makes use of 100 percent renewable geothermal and hydropower energy sources. The clean energy researcher explains that in this case, the energy demand for miners is almost irrelevant to the health of the environment.

There's no guarantee this won't have gimped FP64, Hawaii for example had 1/2 rate FP64 but the consumer cards were 1/8 speed. But even 1/8 would leave the 1/32 NVIDIA cards in the dust. If they don't gimp FP64 it won't leave a whole lot of reason to buy the MI50 for probably 10x the price.

> If they don't gimp FP64 it won't leave a whole lot of reason to buy the MI50 for probably 10x the price. MI50 has ECC RAM support. That's absolutely necessary for high-end scientific compute.

Not at a 10x price difference it isn't, at least if you're at all price conscious and looking for workstations / small clusters. This makes it far cheaper to just re-run simulations as necessary to get the same statistical guarantees with regards to memory corruption errors.

If it could somehow actually sell for the MSRP (which of course it won't), it is a better gaming card than the RTX 2080. The 2080 costs more, and it's flagship feature is something you'll almost certainly want to turn off for gaming since it kills your frame rate and doesn't provide anything most people will notice while playing a game. Screen space reflections and cubemaps are convincing enough when you're zipping a…

$699 matches the MSRP for the RTX 2080: https://pcpartpicker.com/products/video-card/#c=427&sort=pri...

But you aren't usually going to be finding them that cheap. That will probably be the case with the VII too, but we don't know yet.

Presumably hughes is just making a knee-jerk comment about how 99% of PoW systems are doing useless work. Personally I am very skeptical of any system that tries to do proof of useful work like transcoding; it seems vulnerable to cheating.

Its an interesting design for sure. 4x Stacks of HBM2 means 1TBps memory bandwidth at 16GB. Only 60-compute units enabled (maybe 4-CUs are expected to break during manufacturing? Its a weird number for sure...). Since it shares dies with the MI50, the Radeon VII will have 1/2 speed double-precision, making this the cheapest high-performance double-precision card in existance. ------ FP16 compute is supported at doubl…

Would it make sense for them to make a 8GB variant as well? 16GB make it very expensive and actually for gaming it's most likely not needed yet.

So that's why Xeon Phi has been so successful!

/s

Real talk, though. Why do you think larabee is the "right" hardware?

LivePeer uses the Truebit protocol for this.

I'm not familiar with the nitty-gritty, but video transcoding seems to me to be something that can be verified much, much more cheaply than performed.

FWIW, I think they're already launched, so do feel free to break it.
