Checking Nano Review I saw that the A715 is an ARM v8.6Yeah, if this is so, Samsung has been using the same cores for 4 generations now. Cortex A78 was a core announced by ARM in 2020, and the A55 is even older than that.
Exynos A78 + A55 Phone 1280 2 + 6 Galaxy A53 1380 4 + 4 Galaxy A54 1480 4 + 4 Galaxy A55 1580 4 + 4 (?) Galaxy A56
2025 midrange phone with cores from 2020. This would have been excusable if it was like a very low end (<$200) phone. But no, this is Samsung's Galaxy A5x series, which has an MSRP of about $500.
Wait what? Isn't A715 an ARMv9 core?
It is possible that the core clocked at 2.9 GHz could be a Cortex X1.
However, it was recently revealed that the mass production of the Exynos 2500, which was scheduled to be featured in the Galaxy S25, is difficult due to yield issues. This has once again raised concerns about the yield and quality of the 3nm process
With no customers at 3nm, Samsung is converting its 3nm fab to a 2nm line. The company plans to install a 2nm production line with a monthly capacity of 7,000 wafers by the first quarter of next year. Testing will be conducted on the next-gen Exynos chip, codenamed Tethys.
Same source says that Exynos 2500 will not be used in the main S25 series coming early next year. Only the flagship phones coming later in the year will use it (S25 FE, Fold 7, Flip 7). It is alluded that the Exynos 2500 is being ported from SF3 to SF2.They have abandoned 3nm and plan to switch to 2nm. The Exynos 2500 will not be used in the S25.
This sounds highly dubious. Designing CPUs is not easy. Samsung used to designt their own ARM cores once upon a time. It was called the Mongoose CPU, and the last version was the Mongoose M5 in the Exynos 990 from 2020. Those cores were subpar relative to the competition, and it's no wonder Samsung shut down the Mongoose team and scrapped their custom ARM CPU project.S26 with in-house GPU, S27 with in-house CPU?
They first could resurrect their own in house CPU since they have the Mongoose project. At least they have some knowledge. Making a in house GPU takes time, just look at Huawei.Rumour:

As for Custom GPUs... They are already using AMD's RDNA, which is an excellent graphics IP. Semi-custom would make sense to some degree; perhaps Samsung wants to add their own modifications to RDNA. Like how Xbox/PlayStation use a customised RDNA architecture. Also AMD has announced that they'll be merging RDNA and CDNA in the future, to create one unified GPU architecture called UDNA. UDNA sounds like it'll be good for PCs, but not for smartphones perhaps. If so, it would make sense that Samsung would be exploring making a customised fork of AMD's GPU IP.
Sony and Microsoft have more invested in getting it right as gaming and therefore heavy gfx is the main use case of consoles.perhaps Samsung wants to add their own modifications to RDNA. Like how Xbox/PlayStation use a customised RDNA architecture
With RDNA Samsung atleast put themselves in unique position, they werent as good as Adreno but they did better than Mali. You could see Emulators like Yuzu/Skyline taking advantage of that Gpu and produce good results.Sony and Microsoft have more invested in getting it right as gaming and therefore heavy gfx is the main use case of consoles.
For Samsung it's more about just having something that works and doesn't seem embarassingly behind the competition as Mali was not so long ago.
If ARM continue to improve with Mali then Samsung could switch Exynos back to it.
After all it seems very unlikely that AMD will let them use RDNA for WoA SoCs, so they need to go back to either Mali or PowerVR to become a player in that growing market.
Meanwhile makes me think how Huawei's Maleoon fares in this moment.With RDNA Samsung atleast put themselves in unique position, they werent as good as Adreno but they did better than Mali. You could see Emulators like Yuzu/Skyline taking advantage of that Gpu and produce good results.
Mali is Good in benchmarks but when it come to replicate that perfomance in real life it struggle. Like in highend Emulation majority of heavy 3D games would just crash.
So going back to Mali would make Exynos lose advantage, it can't match Dimensity efficiency while having same Gpu.
Samsung Electronics plans to decide on the mobile AP to be used in its flagship product 'Galaxy S25' to be released early next year between the end of this month and early next month
The S24 uses a mix of its own AP Exynos 2400 and Qualcomm's Snapdragon.
It was expected that the S25 would also be equipped with the Exynos 2500, which is currently under development, but as the process is difficult and the yield is evaluated to be insufficient, the market recently has a dominant outlook that Qualcomm's Snapdragon products will be fully adopted.
The problem is the cost. APs, which are expensive compared to other parts such as displays, account for a large portion of the cost, and if third-party chips are used, they have no choice but to accept a high price, which inevitably increases the cost burden.
If issues such as yield are resolved and Exynos is installed, it will be the best for both the System LSI division that makes it and the MX division that makes smartphones, but if not, there will be limitations in using it in flagship products that must show the best performance, so Samsung's concerns seem to be deepening.
The MX division is experiencing a problem where sales are increasing but operating profit is decreasing due to rising costs
The Exynos 2500 was supposed to be the "Dream Chip". But Samsung Foundry seems to have dropped the ball.A Samsung Electronics official said, "We will consider the possibility of installing Exynos until the very end."
Or.....If S25 is another Snapdragon only generation, then it's over for Exynos high-end. Even the competent E2400 wasn't able to offset the bad press the name has. E2500 not existing would only further increase such bad reputation.
I guess it's time to go with Mediatek as the second source and try to prop it up as a Snapdragon rival in the west to reduce QCOM influence.
That or start to dramatically increase the prices, giving Apple totally reasons to make near everything in house.If S25 is another Snapdragon only generation, then it's over for Exynos high-end.

In order cores for "secure processes"?Why is Samsung still clinging to the Cortex A5xx, when Mediatek has demonstrated it's better to get rid of them?
It will be a success if A5xx series will no longer be included in mid-range chips But I guess no one in android space, due to marketing reasons, will dare to release a SoC with less than 8 CPU cores. Even Qualcomm had to spam M cores to keep the magical 8 number goingSamsung based announced the Exynos 1580!

I never said that M cores are crappy, or there is anything wrong with them. The thing is I doubt you need 6 of them in the mobile SoC other than to boost benchmark scores. If all the background tasks can be handled by a cluster of 4 A520 cores, then 4 M cores will definitely be able to handle them sufficiently.M cores are not A5xx crappy cores.
