Snapdragon 855

So it's that time of the year again.
The new Snapdragon is about to be relessed, and this time it's supposedly a more powerful Single Core supported by a weaker tri-core system.
Do you guys think that this kind of set up will be beneficial for dolphin ??


Cheers!

So it's that time of the year again where the answer is "we don't know until a device with said chip is released so Dolphin can be tested on it"

Cheers!

Actually, that's really not great.

Dolphin needs two fast threads. Not one. If Qualcomm is giving us a configuration that only promises one high performance thread, then Dolphin will suffer, or largely be the same as existing chips because it may just be scheduled to run on the middle cluster.

Android CPUs are largely fine as is these days. The issues remaining are some thermal throttling on some phones, and bad GPU drivers we don't care about across all phones.

I was kind of worried about that too. Hopefully there will be at least somewhat of an improvement. I could really use a 20% speed increase in Super Mario. Oh and in Morrowind too of course.

I think the new setup isn’t that bad, 2.4GHz on 3 cores is more or less enough to get within spitting distance of the S845. All the big cores are still big, just that one core gets a higher max clock and a bit more cache to itself. Couple that with the arch improvements on the base A76 design they built on (and the single core being able to run at 2.8GHz), and i’d wager an improvement. The Kirin 980 was able to provide a non-trivial bump in performance (getting near the A10 in terms of single thread perf). At the very least, if thermals still suck, the effective performance at the same lowered clock speed would be higher than previous gen (upwards of 30% single core perf over A75/Kyro 380).

Remember, there's no one "single threaded performance" value. The exynos mongoose had some really good benchmark numbers pre-release.

According to anandtech (https://www.anandtech.com/show/12520/the-galaxy-s9-review/4), those still persisted in the final product. Just with the CPU being extremely wide and power hungry, to the point where the cpu governor had to aggressively regulate multi core frequencies (down to 1.7Ghz max on a full quad core load). Couple that with a spectacularly bad cpu governor from Samsung (their DVFS seems to perpetually miss ramping up frequencies in time). Plus Samsung literally said they nerfed the Exynos M3 in real world to make the snapdragon look competitive. Bottom line, those benchmarks numbers (like the 3600 in GB4) did actually persist in the final product, it just wasn’t feasible

as @helios says one fast threads is meh. if dolphin run on the middle cluster perfomance will be very similar to sd845

SD855 will incorporate something called elite gaming.

but the most important thing is that hopefully come with good video drivers but if this is not the case it would be a real shame

Well yeap SD845 perform better than SD835 for Dolphin-Emu, so SD855 probably will be greater, but we have to see also if they are going to release new Adreno GPU..
At the moment leaked images showing SD855 combine with old GPU Adreno 630 but who knows until they release on real Android Device..
Also most important is power consumption & power hunger which enveloping heating and eventually thermal throttle to Soc..

Apple A12 Bionic showing there magnificent new 7nm CPU killing every other CPU in the Benchmarks but is that true??
Or they cooked Benchmarks remember Apple rare released Benchmarks.. But yeap we all know Apples falling so they should do something cool!
