Especially when you consider the huge TDP and cooling requirements (although they are coming with AOI water loop coolers included)
something doesn't need a 'lot' of cpu but does need lots of gpu such as multiscreen 'real time' 3D would basically be 'better' on threadripper due to extra pcie lanes.

If you only need it for the IO then the CPU won't be running at full chat most of the time, factor in the included watercooler and TDP should be a non-issue

Right but... Use case? Real time 3D is legit (although I suspect high core/thread CPU is still desirable in reality) but what else?

Anything that uses the gpu or equivalent (think nvidia tesla etc) device to do the processing and the cpu is just there to 'oversee' the rest of the system. Pretty sure there's plenty of financial and scientific analysis that is done on things like tesla these days, you could even throw in bitcoin mining. More PCIe lanes means more 'bandwidth' for the external cards etc.

3D CAD rendering, FE analysis, matrix crunching, fluid dynamics, wind modelling, crowd simulations, there's loads of analysis types using software that is designed to max out multiple threads and run off GPU where the availability exists. Such cases are highly parallel and benefit hugely from offloading to the GPU engines. So for my work this would be quite desirable, and potentially expand the scale of project we can model in one hit.
Looking forward to seeing the real world test results. Perhaps Hexus can throw in some serious FE models and 3D rendering to see how it fares in those?
Re: AMD details Ryzen Threadripper pricing, availability and specs
I still think when you're spending that much money (multiple Tesla's), you're unlikely to look at the range of CPUs and go for anything other than the 16 core.

Thats my area of use and tbh I'd expect that sort of test with a 16c32t cpu, especially when it's targeting them lol

To be fair most up until now would have likely picked dual socket boards, they may well still do so because I'm pretty sure EPYC has a dual socket option (nvidia grid and newer version are dual cpu iirc) too but that might be as much down to what is offered to them versus what they need.

The genuine use cases are likely to be few and far between, but do exist. OTOH there's also people out there who'd do it just to be able to run 3 x16 cards at full bandwidth, whether it helps performance or not. It's a way to spread the product across market segments and turn more profit from defective dies (at $549 the 1900X offers twice the resources of a 1500X at around 3x the cost...)
As to TDPs, they're design points not actual power draws. After all, the "95W" 1800X draws 25W more than the also "95W" 1700X/1600X, while the "65W" R3 1200 draws 15W less than all the other 65W parts. I wouldn't be at all surprised to see a 30W - 40W difference in real-world power draw betwen the 1900X and 1950X...

Re: AMD details Ryzen Threadripper pricing, availability and specs
I'm thinking of buying a 16 core 32 thread epic for mining an altcoin. I would need to mine in around 4-8 VMs so I would need a lot of memory. I don't need GPU mining and I don't need anything else out of the system. How cheaply could this be done, considering the CPU is already $999?
