Apple will have to increase core counts again if mediatrk continues to improve the this pace 💻🤔[1] The new GPU architecture from ARM is looking great. I mean... Look at that Perf/Watt uplift over D9200😱. Goodbye Valhall.
[2] Seems like in the CPU department Mediatek put all the balls in the multi-core department. The Cortex X4 cores is clocked at 3.25 GHz and only has 1 MB L2 cache, whereas the SD8G2 has an X4 @ 3.3 GHz with full 2 MB L2.
[3] Seems like they are cheaping out on the CPU caches.
SD8G3 : 5 MB Total L2, 12 MB L3
D9300 : 3.5 MB Total L2, 8 MB L3.
Kinda understandable as the monstrous CPU configuration would indeed take up a lot of space.
What do you guys think?
Honestly the perf/watt uplift over Qualcomm isn't really that great as even I'd have expected, probably partially because these cores aren't really at their ideal operating frequencies, and then they also don't have as much L3 or L2 cache (QC has 50% more L3 and twice the L2 on their prime X4, and then similar cache for a few of their A720's to MediaTek's X4's) - which makes a big difference to total SoC + DRAM efficiency.[1] The new GPU architecture from ARM is looking great.

Where did you see standby?This is ground breaking.
Standby battery life is on par if not better than the 8 gen 3.
Shows that the lack of little Cortex A5xx cores is not an issue.
This is unprecedented.
The era of the A5xx cores is over?

In all likelihood A5xx will be relegated to lower end streaming devices and cheapo phones in the coming years.today we probably are already in situation where even phone's smallest cores should be ARM's intermediate cores instead of small cores

I'd be interested to know how successful Neoverse E licensing has been so far.
Yeah they only released an AE version of A65 so that makes sense.and an automotive AI company whose name I'm forgetting

So are they using the AE version or not?I'm not actually sure that's true. They list the A65 and A65AE separately on their website and in documentation. For instance:
Cortex-A65AE | Multithreaded CPU for Safety-Critical Automotive Tasks
Arm Cortex-A65AE is the first multithreaded DynamIQ CPU for automotive and safety-critical tasks like ADAS. It offers high throughput, resilience, and DCLS for fault tolerance.www.arm.comCortex-A65 | Multithreaded CPU with High Throughput and 8 Cores
Arm Cortex-A65 is the first multithreaded Cortex-A DynamIQ CPU, offering high throughput with dual-thread processing and up to eight cores, for sensor fusion and vision-based systems.www.arm.com
They specify in a number of places that the straight A65 is for non-safety-critical uses, whereas the A65AE is safety-critical.
EDIT: Also I lied about the company using A65 for automotive AI. The company is SiMa for their MLSoC product, which has a cluster of A65 (not A65AE) for embedded vision applications - but it seems like automotive is only a secondary target market for them (after UAV and industrial use.)
So are they using the AE version or not?
Majority of phones can sustain 60%+ of performance for more than 1 hour, for comparison Vivo X90 with Dimensity 9200 could sustain 74% in 60 minutesPhones rarely run flat out for more than a few seconds in real world usage, so this is probably not that big of an issue.
Rumor: Dimensity 9400 CPU core config might be as follows.
Cortex-X5 MP3
Cortex-A730** MP5
** Tentative name; codenamed "Chaberton"
