855 has better performance and it's really noticable in games but I guess u could also use 777 but ngl still both of them are unusable

When it comes to raw Performance it's Sd855 If you want efficient Battery and Balance performance it's SD 778g Question why is 855 called flagship than 778g? A: the answer of that is my first sentence now Shuu Shuu Sd778g fans

The main catch is on display resolution. If you lower the resolution of the display, you will get better performance. This has been done with SD 855. SD778 was tested in higher resolution than SD855. (Device Display Resolution)

This test is not accurate. The 855 performs better in gaming and has superior GPU raw performance.

What? The are vastly different, they are not even using the same cores (A76 vs A78), they literally have nothing in common.

Gnus, Their performances are similar, even though they are from different generations. That's probably what he or she meant.

Marcos, He/She says it was the same but slowed down. I believe that if 778 had the same clocked CPU, it would be much faster than 855. They are just totally different in every aspect.

anon, Yes, you're right, but the CPU frequency has a good ratio like 2.84, which is better in performance. And Adreno 642L, which means L is low for device consumption, is good. My phone, an A90, performs high with SD 855 and can play PUBG on max settings, but it gets quite hot, like my CPU gets up to 78Β°C. Yet, even with that heat, I can keep playing until my CPU reaches 80Β°C, at which point the game exits. What I mean is that the SD778G can play at a more comfortable temperature, better than the 855. However, if you have a cooler or play in the cold, the 855 could be better. I believe both will give you good performance.
