Love the thread title
Anyhoo, here's the deal in a nutshell from my perspective:
1.) Intel 10nm is garbage and will probably leave Intel without anything meaningful for any singular <10watt SoC in 2019
2.) The biggest "problem" for the GPD Win 2 now is lack of GPU resources. That only gives us a few options (
AND ALL of these options are 25-30 watts)
2a.) Amberlake + Nvidia MX150 (or MX250) = This is best combo but would have to cool two distinct places and makes device wider.
2b.) A single Intel solution available now, the 8109U. This is IntelHD655 and has 128MB of EDRAM (fast cache for CPU + GPU)
But GPD probably can't even buy this chip in small quantities 2c.) AMD V1605B. Last I heard about this was lack of support when working with OEM. This could still happen but I think it's unlikely.
So basically 2019 doesn't give that many options and if there was going to be a GPD Win 3
it would need a significantly better GPU to even qualify as a big enough upgrade. And yes it would be more expensive than Win2.
The biggest problem here is the wattage. The Win2 battery is pretty massive (~40Watt Hour). If we used this same battery and ran it at 30watts (Probably have to go up to 14v or whatever, too many amps at 7.6v) the battery would only last 80 minutes. Without going crazy, if we hit 60 watt hour battery, it would probably be the best trade off between battery life and weight.
For those wanting a cheaper Win2 there is already an option available. It's the 3965Y:
https://ark.intel.com/products/122698/Intel-Celeron-Processor-3965Y-2M-Cache-1-50-GHz-This is mostly a 7y30 without Speedstep and a bit less cache. It would still offer close to 60-100% more perf over Win1 and is the same socket as 7Y30 (Read: Should be pretty much drop in compatible with Win2 board)
On linux you could play a lot of Gamecube titles with MESA Vulkan drivers, but on Windows we still need to wait for improved drivers and integration on Dolphin. OR just wait for VideoCommon to be updated on Dolphin and get DX12 support back in mainline Dolphin.
PS2 wouldn't be as good as Win2 proper, but some games would work. Mostly the 3965Y should offer 60% of CPU perf compared to 7Y30.
But technically a 3965Y Win2 "Lite" edition could probably be priced around $425-450
Obviously this is just technical side of chips we'll be able to use when trying to forecast what is most likely going to happen.
For features, I'd like:
Clickable Analog Sticks L3/R3
Analog L2/R2
Get rid of mouse / xinput switch
Instead install Optical Mouse sensor like P2 (just include Right-click and scroll function somewhere)
Always on Xbox controller and always on keyboard and mouse
