    Their midrange SoC fare pretty well, though.

      We the consumers do NOT want to lose another competitor.

      Back in 2015 we had architecture designs from Nvidia, Qualcomm, Samsung, Apple, and Stock ARM. In addition to Stock Mali-GPU, we also had Apple, Tegra, Adreno, and PowerVR. We also had better price control in the market. And each year the upgrades in efficiency and performance were notable.

      Now?
      We're merely dreaming.

But low-end & midrange move the most volumes, hence emphasis rests on it. Also flagship Exynos never show up in midrange except FE.

          Aluminium mid-frame molded with plastic where necessary. This is what Samsung has been using since at least 5 years now. It holds the battery, motherboard & the entire phone assembly, and dissipates the heat from the battery & CPU using thermal pad towards display. Watch this teardown:
          Galaxy M35 (aluminium with vapor chamber) https://www.youtube.com/watch?v=cjiHAqxZMIg
          Redmi Note 13 (aluminium WITHOUT vapor chamber) https://www.youtube.com/watch?v=Pt8AtX9H9A8

          Not defending Samsung, but I was only pointing out that they have been successfully relying on complex techniques to make up for Foundry's inefficient node.

                Rodolf, 13 Mar 2025That's like changing my eating with right hand to left... moreYeah, South Korea should just sell its strategic sovereign world-#2 fabs to China. Can't imagine why they haven't thought of that one.

                  Exynos has bad reputation only thanks to Foundry division which is far behind TSMC. The issue is power efficiency & technology development has been trailing to match vs TSMC. Also due to skewed marketing their Transistor density is low for any given node. So example -
                  Samsung 4nm = TSMC 5nm
                  Samsung 5nm = TSMC 6nm
                  Samsung 10nm = TSMC 12nm
                  etc.

                  Exynos division is not given choice , they must use Samsung Foundry because Foundry itself is moving slow & struggling to keep customers which give TSMC 1st preference. Hence Exynos try to compensate by putting less power intensive CPU & less GPU cores & lower Hz to counter overheating. Recent emphasis on Vapour chambers that are very large than competition along with display side heat dissipation via Aluminium block is to compensate for less efficiency of Samsung Foundry.

                  In the long run, however, it helps Samsung compete vs Chinese Gov subsidized companies especially in entry level segments to differentiate with 5G & AMOLED thanks to money saved via in-house Foundry. Hence Samsung should not sell its foundry because it manufactures its RAM, UFS & SSD chips on them as well. Selling Foundry will make Samsung less competitive in these sectors.

                      Meanwhile samsung exynos is known as google tensor elsewhere

                        That's like changing my eating with right hand to left hand!

                        Just sell the whole semiconductor department to someone capable of doing better, like to Xiaomi or Huawei.

                          Kids, this is why you should never be a conglomerate.

                            fren, 13 Mar 2025samsung should just cancel the exynos business and focus on... moreMore competition is good, plus exynos used to be good, there is potential. Remember snapdragon 810? Google tensor is the hopeless one.

                              Hopefully this will bring better optimization in future designs.
                              Design wise, Exynos 2400 is showing a good rebound, and 1480 onward also are pretty good for the class.
                              And 4nm Samsung foundry is actually quite decent. Snapdragon 6gen1 uses Samsung 4nm, and it sips battery.

                              With Qualcomm pushing the prices of their SoCs (and for good reason, they're the best now with the Oryon cores), Exynos is needed more than ever to at least provide an alternative competition.

                                Exynos was always just competitive enough. Not great, not terrible. But competitive enough doesn't turn heads. They need a winner like Apple's silicon was for Apple.

                                    Personally I also find this move questionable. Because there is not a real silicon compiler, microarchitects and the experts on the silicon process should work together to actually create implementable and efficient solutions, if they separate them, they'll just create additional work at the end, when they'll have to coordinate it to actually create a floorplan and stuff, also I'd expect it to make the chip bigger in the end and less efficient.
                                    If their plan works out however, that would show that they haven't actually been cooperating inside Samsung LSI. Still a risky and potentially stupid move.

                                      Ew Exynos... I won't buy it anyway.

                                        It would be a good move. encouraging the competition between Mediatek's blazing fast Dimensity 9 series chips. and Snapdragon's 8 series chips. they're terrible now. but the future. SHOULD be good.
