    Can't they just make ss 865 cheaper.
    They can even save money on designing new chip.

      Anonymous, 07 Oct 2022Even 720G is more powerful than 835. So it isn't similar.Only cpu is more powerful. Gpu is 10% lower.
      778g gpu is between 845 and 855.

        Anonymous, 08 Oct 2022Wrong math ... If SoC efficiency is 1.00 point , then ... ... moreThat efficiency comes at the same level of power the previous chip produced. And the efficiency is not always used to prolong the battery life but rather push performance figures because apart from the efficiency consumers demand raw performance increase

          The 7 Gen 1 is not even available for everyone and only seen on Oppo's China Reno8 Pro, and yet we already seeing Gen 2? I don't see any problem slowing down the pace. Even 750G and 765G is still more than enough for most people.

            Anonymous, 08 Oct 2022It is not. It is even below 690. 690 is a new chip. But 835 is really old now.

              Kurokaze, 08 Oct 2022750≥695>732G>720G≥690>835≥730 >820>712 I... moreIt goes something like this:

              (QSD 810-level) QSD 632, 460, 662, 665, 636, 680, (QSD 820-level) 675, 678, 660, 480, 670, (QSD 821-level) 710, 712, 730, 732, 720, (QSD 835-level) 765, 690, 750, 768, QSD 695 (QSD 845-level), QSD 778, QSD 780, QC 7g1, QC 7g1+ (QSD 855-level).

              Note: I didn't include ye olde chipsets like QSD 650, 652, 653, or reference to older flagships like the QSD 805 and below. It's kind of pointless to mention them here.

                Anonymous, 08 Oct 2022It is not. It is even below 690. 750≥695>732G>720G≥690>835≥730
                >820>712

                I think you're confused on something. The 690 is the same as the 720G

                  Anonymous , 07 Oct 2022If every year efficiency increases by 10% then in 10 years ... morethe efficiency number means the new chip can run at the same performance with the older one but with lower power consumtion. and the increase % in performance means the new chip run at higher performance but also with the same power consumtion. you can only take one of those 2. sp every year you will see 2 increase in number but manufacture always priority performance. thats why you will not see those chips with the same performance but better power consumtion

                    Anonymous, 08 Oct 2022Wrong math ... If SoC efficiency is 1.00 point , then ... ... moreMaybe he's thinking it's using -10% less battery upon each succession.

                    Year 0: 1.0000
                    Year 1: 0.9000
                    Year 2: 0.8100
                    Year 3: 0.7290
                    Year 4: 0.6561
                    Year 5: 0.5905
                    Year 6: 0.5314
                    Year 7: 0.4783
                    Year 8: 0.4305
                    Year 9: 0.3874
                    Year 10: 0.3487

                    ...so yah, after a decade of consistently 10% decrease in power draw, you're still looking at about One Thirds of energy used. It's not 1% or 0%. It is inversely-exponential.

                      Year 10: 2.593

                      After 10 year, SoC should be 2,6x more efficient. Obviously they are not.
                      8g1 inside a phone powered by S4 Pro should give 160% more battery endurance.

                        Anonymous, 07 Oct 2022Even 720G is more powerful than 835. So it isn't similar.It is not. It is even below 690.

                          Peter-B, 07 Oct 2022As far as I can tell there are only two phones with the 7 G... moreJust a heads up Peter about the efficiency and performance claims. Those are the theoretical claims made by ARM, and they've always been exaggerated to some extent. If you go back to the announcement, you see they are comparing it to the QC 8g1, which is built on Samsung Node, while the "new" chips are using TSMC Node. There's an increase in cache which can amount to the performance increase in synthetic tests.

                          The battery life increases are a "known secret" in the industry. As you increase the frequency the chips run faster and faster, but not proportionally so. There's a point of diminishing returns, which is why we need to add more cache, higher bandwidth, more memory, and other co-processors to help with specialised computing. Also at the top-end there is a lot of instability so higher voltages are used, which means more energy and heat. The so-called power curve that is mentioned, and it's the weakest here. If you take an older chipset running at 100% performance, it will use a high number of energy. Now when you introduce a new chipset which has a longer curve, and you test at the same 100% performance, you realise it is lower on the efficiency curve, and isn't at the top end. Then you can make "technically true" claims about 20% efficiency, when in real life you may only get 1%-5%. We've seen Intel use this same tactic throughout their 14nm lineup from 2015 to 2019.

                          The truth is that the 2023 cores (X3, A715, A515) are a slight refresh of their 2022 cores (X2, A710, A510). And we shouldn't expect the new QC 8g2 to be that much different to the QC 8g1+, but decently better than QC 8g1. And the same goes for the rumoured QC 7g1+ (in this article) versus the vanilla QC 7g1, which wasn't impressive, and barely matched the QSD 778 chipset from 2021.

                          Everything has been pushed back by 1-2 years by the pandemic, even Apple has taken advantage of it (A16 vs A15 vs A14). For a proper generational uplift, we need to wait until 2024. That's when TSMC's next-gen node will be in full production with their 3nm lithography. Also the ARM Corporation has different divisions and teams. The Cortex-A730 is supposed to debut then. It's designed by their European Team which has a stronger track record than the US Team, when it comes to actual performance and efficiency gains in the middle of the energy curve and real-world testing.

                          The other truth is, a well-optimised software (ie Custom ROMs) can yield a great uplift in real-world use for performance and efficiency (ie Against Bloated StockOS). So the aging QSD 855 processor can contend with the newest phones running the QC 8g1 chip, and the likes of the QSD 870 versus the QC 8g1+. But things will definitely change for the next-gen processors in 2024.

                            Lg awesome, 07 Oct 2022Its like a rebranded snapdragon 820 😂😂Even 720G is more powerful than 835. So it isn't similar.

                              Anonymous , 07 Oct 2022If every year efficiency increases by 10% then in 10 years ... moreEfficiency take consideration both perfomance and power consumption, if soc is efficient doesnt necessarily mean has more battery life or is better soc at least in phone.

                              Cpu can be effiiency but using lot of power hence its not good for phone, good example is Dimensity 9000 or Snapdragon 8 gen 1, they have Cortex X2 core which is more efficient than Cortex A77 in Snapdragon 865, but for it to be efficient it need to use 4W, which is lot of power for phone soc, hence even though its efficient it cause lot of heat.
