This is a first time I'm thinking about skipping new Exynos SoC. It's not much info about the chip as of now but from what I can see Samsung has ditched Cortex-A73 and continue to utilize their custom M1 cores that are present on 8890.
We would need to wait for a proper Anandtech review of E8895 to get more details but for now all the benchmarks clearly exposing M1s, not M2s.
CPU single-threaded scores are pretty much identical to 8890.

Mali-G70MP20 is interesting but we get terrible ARM drivers that are far worse then Adreno this days. Mali GL ES driver doesn't support buffer_storage and driver updates cycles are linked to a major OS updates, driver updates are not as frequent as Adreno.

Also there are two versions of 8895:
Exynos 8895m = 2.3ghz , 18 gpu cores
Exynos 8895v = 2.5ghz , 20 gpu cores
Looks like Samsung just used the weaker one so there wont be a massive difference in performance between the two S8 variants.


M1 details are scarce and benchmarks isn't impressive. SD835 might be a better choice for emulation this time.

Their custom cores are only lightly customized versions of the A73's, so it's not a big deal. In fact the lack of raw performance uptick is likely because Samsung focused on fixing issues and improving overall performance longevity instead of bursting to loads that cannot be sustained. As for the GPU drivers, Bifrost is probably the closest thing to working we'll be getting from ARM. Midgard is likely going to remain slow. Also the drivers being tied to OS updates is rarely an issue with the chip itself.

Exynos 8895 in single core GB4 has 1974 vs 2059 SD 835. So exynos is not far behind SD. But drivers much better at Qualcomm

M1 means it wasn't touched since 8890 (if this is indeed correct they're not a customized versions of the A73's, M1 likely shares a lot common with A57s). You could expect overall performance longevity/sustained performance improvement due to the new 10nm vs 14nm on 8890, not CPU design eg SIMD/NEON, narrower 2-wide decoder.

Adreno driver updates isn't as tied to OS as Mali (different release cycles, frequent revision submissions to partners branch, OEMs can pull the driver more frequently).

Obviously my point of interest/disappointment in E8895 is tied to Dolphin, drivers clearly an issue in this case

Mali driver updates aren't tied to OS. You are confusing an OEM decision with a vendor decision. Also the Exynos 8895 is using M2 cores, so your sources suck.

Right, they're not tied to Android at all, it's just ARM release cycles are different so vendor is never pushing updated revisions without OS update. Obviously isn't tied to OS isn't it?

M2, great, you must have a link to your source?
