I am looking to pick one of the 4gig versions, for the primary reason of a portable emulator. I have created some with Raspberry Pi's before but want more power and to be able to play steam games / older windows games. I have been comparing LattePanda and UpBoard/Core. They look basically the same from a compute perspective. Same processor and ram and X86 windows support. I have seen videos of upboard playing gamecube games https://www.youtube.com/watch?v=SKUudCSUFn0 I have not been able to find confirmation that LattePanda running Windows could do that. I suspect it should as it is same basic hardware. I prefer latte panda because lower power requirements, audio out jack, SD card slot, onboard BT/WiFi. Shipping / Tax is much cheaper as well. I just don't want to buy one and a screen and have it show up and not run similar to the youtube video I posted.
Anyone have experience in this area or can speak confidently that if that video uses same process, ram, OS, that I shouldn't have anything to fear?
Thanks

I don't think you have ANYTHING to worry about. The Atom in the video you listed is... Well, an Atom. It's single thread performance is ~1/3 as powerful.

Even with the lower clock, the Alpha's Core M3 uses the mainline architecture (Kaby Lake) vs the Upboard's Atom (Cherry Trail). The Upboard CPU just won't compete. The Alpha's CPU wins hands down.

(Upboard) Cherry Trail GPU
12 execution units @ 200mhz base clock, 500mhz burst.

(LattePanda Alpha) Core M3-7y30 GPU (HD 615)
24 execution units @ 300mhz base clock, 900mhz burst.

The LattePanda Alpha will make the Upboard look like hot trash.

I might not have been clear, I am not looking at the alpha but this one https://www.lattepanda.com/products/3.html the "regular latta panda" with 4 gigs of ram. I would love the Alpha but it is a lot more expensive. The 12v usb C is also worrisome, as I would need a new battery pack. Doesn't seem like there is a good selection of 45w USB C battery packs available. It does make me look a little more at the Delta because I didn't realize price was close, but the 12v still scares me.

Thanks for the details on the processor difference with your links and info that is helpful.

Whoa, yeah, I guess my first post doesn't exactly help. The "regular" LattePanda has a Z8350 just like the UpBoard. You'll see similar performance as shown in the video within a margin of error for most things. The only thing I could imagine differing would be ram speeds, I imagine both are DDR3(L), the upboard is 1600mhz ram, the LattePanda is... Well, I can't find out any info on that. It could be figured from CPU-Z if someone here wants to check it. It's likely at least 1066mhz, it could be as high as 1600mhz. I wouldn't worry about it TOO much. I've seen various reviews on the LattePanda, and it seems to throttle pretty heavily if not cooled well, so you'll definitely want to get adequate cooling if that's the route that you go.

Not a problem on your first post, it was still good information and I learned a new tool in the links you sent out on CPUbenchmark which is very handy.
As for the cooling. I was planning on getting the heatsink with fan from the store. That looks to go best on the bottom of the board. What about the top, should I think about any heatsinks for that? It will be in a portable enclosure, so I do know I need to dissipate the heat. There is a sticky on cooling mods so I will also check those posts out.

The PI3 I have does get hot but with a fan for exhaust at bottom of pi and heat sinks on the 2 chips I never ran into issues.
I think after that I might take the plunge!
Thanks for all your help
