Yes, you are right, but they are NOT advertising Vega FE as a gaming card.
But they are advertising Rx as such which uses the same uarch, besides titan started -and is the market leader in prosumer GPUs, and the titan is judged on a mix of gaming and semi pro, it excels in gaming- Vega Fe should be judged accordingly.
An anology would be Vauxhall bringing out a new hatchback car, and saying to everyone it is targeted for carrying the shopping/kids to school and shouldn't be judged on its driving experience-when the market leader ford fiesta is judged on such things and excels- just like every hatchback is judged on certain parameters that's the standard in its class. (Jack of all trades)
In the GPU world the prosumer cards are the hatchbacks, except they are expensive premium products unlike small cars.
Consumer = gaming.
Prosumer= uber gaming/gpgpu/semi professional mix (uber price)
Professional= uber gpgpu compute, stable certified drivers (crazy price)
What you and other people are suggesting is that AMD purposely turned off great gaming performance for that card ie artificially segmenting against the market expectations, which is daft.
You better believe if Vega Fe had uber titan like gaming capabilities they would enable it and market it as such, they are not because frankly it cant-hence this rubbish about just for game development.
The alternative to that Is what I mentioned in an earlier post, that AMD is pulling some masterful sandbagging for an early Christmas present, not impossible but extremely unlikely imo.
Im dismissing entirely the notion that AMD is doing neither of those and is working on an unready driver that is going to increase performance by 35℅ in one month of work- they have had 8 months to work on drivers- most of the gains would be in code already.
Edt; Just to restate- I would love some crazy driver action as I would probably go buy one, also I still think the bandwidth limitation rumours are fishy as hell, I expect if true just fixing that would bring 20℅ or so I would think, but would also hamper compute, so they would be shooting themselves in the foot with Vega Fe either way.
