The Mediatek Dimensity 9300, the succesor to the Dimensity 9200 will apparently released soon in the coming months. Till then, we have has several leaks about this chip and they paint an interesting picture.
The CPU of the Dimensity will apparently have a configuration of 4 Cortex X4s + 4 Cortex A720s. There is no Cortex A520 or any other Cortex A500 series core.
This leak was discussed in this reddit thread
I myself thought that such a configuration would be an inefficient thermal disaster, but the insight obtained from reading the above thread proved otherwise.
They speculate that the D9300 will have a single Cortex X4 core clocked at high speeds (3 GHz+) and the 3 other cores will be low-configured Cortex X4s with less caches and lower clockspeeds.
Apparently these 3 low-config Cortex X4s will carry the multicore performance. They mention how such a low-config Cortex X4 is actually more efficient than a high-config A720 (running at high clock speeds; 2.8GHz+, which is what SoC vendors have been doing for a long time). This is possible because the Cortex X4 cores have a wide design with higher IPC than the A720.
Speaking of the A720, we come to the other 4 cores of the Dimensity 9300. Apparently these A720s will be the low-config ARM unveiled at TC2023, running at a clock speed ~2 GHz. These four A720 cores will spiritually replace the four Cortex A510 "efficiency" core used in previous designs. This configuration of four A720 cores is similar to that in Apple's Bionic chips. The redditors mention the A720 can serve the purpose of an "efficiency" core well, although one person notes that the A720's leakage below 0.5 GHz will destroy it's efficiency.
Thus, the Mediatek Dimensity 9300 might represent the beginning of a new era, where the Cortex A5xx are no longer a Smartphone SoCs efficiency cores.
What are your thoughts on this?

Update 22/07/2024 : I have decided to rename the thread from "Dimensity 9300; The end of an era for the Cortex A5xx core?" to "Mediatek SoC Thread", so that henceforth the discussion may not be limited to only the Dimensity 9300, but also other Mediatek SoCs, such as the upcoming Dimensity 9400 and even Mediatek's rumoured Windows PC SoC.
