damn! D8450 is way better in performance stability and battery life than D8400. test it on OPPO Reno14 Pro vs Xiaomi 15T. OPPO Reno14 Pro got 15 hours for daily usage, while Xiaomi 15T got 9 hours for daily usage.

theres a difference as the software for xiaomi and oppo is different. to make a fair comparision, you should use both phones with xiaomi's android 15 and play a 4k video in youtube and compare the battery drain

You can see in the note, they said 8450 is the same chip as 8400, just changed something for better thermals and sustained performance.

blud, Are you idiot? It says 8400 ultra is same as 8400 not 8450 8450 is a better SOC than 8400 and first of all it comes in 8350 series

They are the same they both give the same performance just that 850 is on more phones and some of those phones have better cooling systems so the 8450 perform slightly better that the 8400 ultra. Meaning they both are the same if you find 2 phones with those SOCs pick based on other specs

Everything same, MediaTek is renaming the processor every time. Just go to Snapdragon: better cooling, performance, long time stability, etc.
