Snadragon 820 & Exynos 8890 Dolphin performance Discussion

I read that the 820 will be made with Samsung's 14nm process. So, hopefully that and it's better(well at least according to Qualcomm) power management translate to longer sustained loads and less throttling.

No.  Qualcomm marketing "it's better" BS can leave.  It's not going to be better.  Sustained loads are not a priority for Qualcomm because they don't care about power use they want to cater to casuals.  They are a layman's processor maker.

or wait for an android phone whit intel core i7 + Nvidia GeForce GTX 970.xD

Nvidia X1 device are easily reaching the playable range and saying that they are all the same is a disservice to the chip makers actually doing a better job.  Just because his project is still a work in progress doesn't mean it should be damned with zero praise and generalized to hell.

In order to have an acceptable performance (subjective) on mobile SoCs you'd need at least GL ES 3.2 + buffer_storage implemented (Mali might get ES 3.2 but without buffer_storage= bottleneck continues) this would be absolute minimum specs. In order to have close to a full speed performance you'll likely need Vulkan and Vulkan backend, potentially it could utilize lower CPU clocks, when SoC is throttling/less clusters=win (no specs yet so purely in theory)

btw the SD 820 will be powered by unicorn sparkles, so this thread is pointless.

Yeah but the Exynos 8890 is supposed to be powered by Diamond Unicorn sparkles,  so it would be even better.  Making this thread even more pointless.

I don't know guys. Call me an optimist or naive but, I think we're only a year or two away from great dolphin performance on our android phones. The next version of android should hopefully have all the graphics APIs we need for proper dolphin support and the next generation or two of mobile SOCs should be efficient enough(through a smaller dye process) for sustained performance. Well, at least that's what I'm hoping for anyway.

Yeah, we're not that far away. Better video drivers, CPU designed by engineers instead of marketing (nobody needs an octa-core one), and we're almost there

But of course, only for light games. There are still plenty games which doesn't run well on the desktop either...

I'm not too sure about Exynos 8890 since it's lower cores are still A53s @1.5GHz so once it starts to throttle expect thermal config to aggressively utilize lower cluster, pretty much the same as on Exynos 7. This octa-core thing isn't really good for emulation

Okay!  So both the LG G5 and Samsung Galaxy S7 have been officially announced.  Somehow, someone has already done a teardown of the S7 and found something interesting.  It has a heat pipe that's supposed to draw heat away from the cpu.  According the GSMarena article here , even when running multiple benchmarks, the phone kept it's internal temperature in check.  This could bode well for better sustained performance in dolphin.  I can't wait to see how well it runs on the S7 and G5.
