    JakoDel, 08 Oct 2024imagine spreading misinformation this confidently. how can ... moreOpenGL-ES 3.3 (Embedded version, limited hardware acceleration, for portable devices and OS Embedded such as Android) = OpenGL 2.1 (Full version, complete hardware acceleration for workstation and desktop)

    OpenGL 2.1 = DirectX 9C (latest API version in Hardware Accleration for OS Desktop Windows XP)

    In fact, some games that use the Directx 10 (OS Desktop Vista), forcefully turn under the emulation of the same (Wined3D = Software, to support OpenGL 4) and in general, they also go wrong with medium FPS that do not go beyond 10-20 FPS In that type of GTA style games (leaving out the disgusting alternative mods that also impoverish the minimum requirements and without the CPU side computation of the shadows), in fact therefore, using all the computational power on the CPU side. (not to mention the generation of heat and thermal throttling)

    Vulkan side, essentially and so far, the lack of hardware (or software) extensions to the correct graphic management of the Mali GPUs (and derivatives): Shader Model Hardware technically old or not fully compatible with the requirements of a Chronos (see OpenGL-ES )

    So-affected members are all those OEMs who persist in using Arm-Mali technology (so it's not just an MTK speech)

    This type such as System On Chip therefore is not preferable to the Custom SoC of a Qualcomm, which cleverly, actively participates in the Mesa Driver Project and in fact, making it possible for the real retrogaming in hardware acceleration. (With his Adreno GPU, much more similar to a discreet Apu for laptop and non-embedded as in the case of the GPU-Arm)

    To cut short: when I bought the SD-8 Gen 3, I found myself in a position to not be able to play my GOG bookshop (or at least part of those games of my Gog bookshop) on it. (Since relatively new soc, natives fallaci and Mesa driver drivers absent)

    From there to about 3 months, the first Mesa drivers were released for this part.

    Now I can play a 2013 Tomb Raider in Directx 11 (Wrapper Mesa Vulkan 1.3 fully compatible with the Chronos requirements and the Shader Model Hardware), High Settings, 60 FPS and without problems of any kind.

    Before it was not possible.

    What I want to say;

    - It is essentially useless to buy a product, which on paper declares to you 1000 (like the Native Qualcomm drivers of course), when the lack of adequate software support, makes that initial figure drop to 100.

    In summary, you will have a Ferrari, who goes on a medium sedan on track (because it lacks software support), so you will be limited in the use of that hardware and that software.

    If MTK had had the mystical wisdom of those who look to the future, at this hour I would have gladly used a MTK SoC in my device.

    But until proven otherwise, it is not so at the moment.

    In the future, an opening would be possible at least on the GPU documentation side, a documentation that is currently non -existent (Copyright Arm).

    Moral: Because if you are a real gamer, you don't let yourself be easily combined by the screen numbers, by the games of a PlayStore and members.

    Because you don't only look at the technical side but also to the practical side of things.

    And to do this, there is a need for a lot of humility with yourself and a lot of intellectual honesty.

    Two qualities, which are almost non -existent per day today.

    Here is the explanation of a steamdeck and an Mid-Gen smartphone (on the other hand, very consumer park) of the competition. (and which fall within the famous 1000 bags)

    It is not disinformation, on the contrary;

    - It is to wake up who still sleeps. (moreover, who sleeps chasing the dreams of others and not their own)

    Especially if the portfolio is not that of the manufacturer X, Y, Z, but it is always that of consumers that pays it. (and their frustration in discovering that everything is marketing, or deception of perception)

    IMAO.

And when gaming, its super smooth but, gets really super hot then throttles around 30-45minutes of Genshin impact. My cousin's Xiaomi 14 that has SD8gen3 appears much better in thermals though also throttles at some point but not as hot as the 8gen3. The DM9400 will surely be better at thermal handling.

            MagicMonkeyBoy, 07 Oct 2024I would like to try a D9400 in an Asus Rog 9 Pro when launched. Probably, you would regret the purchase, especially if the Asus cost you 1000-1300 bags (100 bags less than the SD counterpart).

            And the reason would be very simple; the Immortalis G925 GPU (aka MALI), is affected by the same problems as the previous ones.

            The impossibility of going beyond OpenGL 3 and the lack of support for the Vulkan API and therefore, finding yourself with an emulator in X86, which only runs titles in Directx 9.0/9.3 (the latest API used in the XP environment), and at most, some spurious titles in DX10 from the Vista era, since, there are no public documents of the sources and hardware operation schemes.

            So you should be satisfied with a very simple and basic implementation in a VirtIO environment.

            You would then have the regret of having a SOC, which however mature in terms of performance, in practice you would not be able to use it to its full potential.

            The regret of finding that even a medium range SD SOC, would do the same fps in games. (because more supported by the GitHub and GitLab community)

            So in analogy with cars, you would find yourself with a Ferrari that goes like an average sedan.

            Because, those who buy a high-end device and have Gaming in mind (the Desktop one), do not do it for the "playstore games", nor for the "stadium fans", but have in mind practicality and innovation even in the retrogaming field.

            They do it, because they love Gaming.

            So, the best advice I can give, as a passionate gamer, is to spend those 1000-1300 bags, for a Real Handheld PC.

            Maybe a SteamDeck (which would save a lot of bags), or a Legion Go (even better than an Asus)

            With the rest of the 1000-1300 bags, you could buy a mid-range device for everyday use.

            But if you have in mind that an MTK SOC, today, is for "gaming", you continue to fall into the marketing trap.

            Marketing, usually, needs the "blood" of buyers, to quench its thirst.

            Mine are obviously simple observations, but they are observations that would like to make you reflect on the use you make and will make of a device that you will always pay a high price for; your pockets.

              According to leaked information, the IPC (performance per clock) of the 9400 surpasses that of the A17 Pro, while the 9300 is only on par with the A15, which is still an impressive figure.

                I would like to try a D9400 in an Asus Rog 9 Pro when launched.

                    Cortex A17 was more powerfull than custom Krait on Snapdragon 805.
                    Cortex A9 was more powerfull than Qualcomm's Scorpion.

                    X925 seems to be more more interessant as despite an heavy frequency difference, 3,63ghz on 9400 and 4,47ghz on 8 Gen 4, single core performance is not that different.

                    Cheating ? It wasn't ! every modern soc on a modern OS use task scheduling and adapt cores frequencies to the application.
                    If you install a CPU monitoring app, there's not any overclocking at any moment
                    The article everybody refer to was writen on Anandtech, is based on a single benchmark : PCMark.
                    On PCMark, without that "cheat", only little cores are used...do you think it's normal ?
                    On this test, there's a webbrowsing simulation, as I said, only little cores are used...when you open Chrome and start webbrowsing, big cores work.
                    I did the test on Redmi Note 8 Pro. Asked Anandtech's guy to do the same...he refused ! What kind of journalist is he? Refusing to verify what he wrote !

                    According to LinkedIn, the guy work now for...Qualcomm!!!

                      D9400's best flagship so far of all Mediatek SoCs that can match SD8 Gen4 or X Elite performance.

                      Hopes that the D9400 has the same power consumption as D9300+ if there is a improvements in power efficiency after bumping its frequency.

                      Nothing special since, the same armv9.2. But the numbers increases.

                        RedMagic User, 06 Oct 2024Well unless they go and put customized cores on their next ... more1. MediaTek uses higher clock speeds - Between last year's D9300 and 8 Gen 3, the only thing clocked higher in the Dimensity chipset was the GPU. The CPU clocked speeds, however, were lower than 8 Gen 3
                        2. Cheating in benchmarks - While it may be true "in the past", that's not the case now. You can watch some reviews from GeekerWan showing just how fast MediaTek has caught up to Qualcomm
                        3. Using customized cores - While this is a valid statement, using PC micro CPU architecture on a mobile SoC isn't easy

                          People seems skeptical of D9300 and D9400 because of the usage of many X core. Phone will prone to overheating if you run benchmark especially with D9300 and newer design. But when you're using it daily, it's barely maxing out the 4 X core. The clever design of MTK using multiple X4 core and A720 as the "small" core in D9300 is that you can get task done at a faster rate while using same energy. This is why the core were significantly slower than normal A720. A720 are normally pushed so that apps can run on it and not being slowed down.

                          A520 can also be pushed to do the same things with the same time as A720 except it will require more power and generate more heat. Ex A720 running at 2.0Ghz can do 5task on 30sec with around 2w. A520 cores can do it in 2 ways. Either takes longer and 1min to do 5task and consume 2w at 2.0ghz or takes 30sec to do 5task at 4.0Ghz with 4-6w of power.

                          One of the good thing in this design is that, it costed MTK the price of die per wafer because it's a bigger SoC. And from what seems to happen with D9300, MTK lowered their profit margin on each D9300 SoC as device comes with D9300(k70 ultra) aren't that pricey while SD8G3 weren't even adopted in lower priced device. This means QC raised the price of SD8G3 instead of lowering profit margin. Of course the next gen both are raising prices. Tsmc 3nm are pricier than 4nm that are currently used in both.

                            - It is the Most Supported at Software level.

                            I have a RedMagic 9 pro with SD8-Gen3.

                            If it had come out with an MTK9300, I personally would not have purchased it.

                            The reason?

                            Lack of OpenSource on the Driver side and Lack of Software support for those Drivers.

                            Aka, MESA.

                            Unlike you minds, who focus on performance, benchmarks and numbers in general, my mind would be more inclined to think of a SOC that makes its performance efficiency, the pride par excellence.

                            It means that if, for example, an MTK9600, was thought, designed and built around maximizing the efficiency perf/watt and around the Software (the OS, its libraries and external Libraries), we would no longer need "4GHz" impossible to manage even by a REDMagic in its devices!

                            Rather, a SOC that worked for example, at 2 GHZ, but that would guarantee 100℅ of performance, software compatibility and Optimization, would be a hardware and software "miracle".

                            I bet that an Apple, would be an example of how to Optimize.

                            Except that from Apple, usually only the Marketing is copied, and NEVER the concept of Optimization of the parts.

                              Anonymous, 05 Oct 2024All are Arm v9.2. As Cortex A55 managed to run with A75, A... moreTry to think of ARM V9.2 wilder as in terms of scalable SIMD extensions, improved accelerator interconnect on core or micro cluster. Don't think of it related to core - cluster mesh in form of DynamIQ. Which by now goes to 15 core's with up to 32 MB of shared L3 victim cache (far from it and on older versions in current SoC's QC 4 MB and MTK 2 MB). The X925 is and only to extent so far one utilising SIMD and any interconnect for others is optional and thinking mainly to A725 by others so far from ARM A series. Interesting for me would be a micro server two core L2 shared version of A725 with even wider SIMD and similarly unified between those two and interconnect to good mining full costume ADSP. You can get one order of magnitude (10x) more performance in FP and high parallel processing in general performance increases per W (especially when you don't need a lot of integer). It's a shift from being bottleneck to actually coming in lead to X64 counterparts (especially when it comes to specific evolving matrix ROP accumulations or such trough DSP interconnect). I personally am not fun of victim cache buffer's nor increasing lateness regarding DDR. So it's time to go with HBM in SoC's if you really want to continue with high parallel to moderate number of threads all good feed future gains. For me that's critical for large scale GPU's, DSP's... progress on SoC's and in generally regarding efficient computing.
                              Other contrapart of equation is good documented and need adopted ADSP architecture that develops can use and you are not getting that from ARM, QC, any GPU vendor and so on.

                                RedMagic User, 06 Oct 2024Well unless they go and put customized cores on their next ... moreLet's be honest, you've never use mtk before. This is coming from me who's used Helio X20 on Leeco le x3(good design but bad performance, atleast at the time), I used Helio G90T (the 1st comeback chip before dimensity 1000) on the redmi note8pro, then I used dimensity 1200(really good chipset even coming close to SD870) on the Redmi k40G (f3 gt global). Then I used dimensity 9000 (the 1st chip to ever beat sd8 gen1 not the plus version) on redmi K50 pro. After that I used dimensity 9200+(good chipset but got bad efficiency due being overclock over the normal d9200). And now I use k70 ultra with the dimensity 9300+. And oh boy, the chipset is indeed very powerful. This is coming from someone who's been using mediatek almost all the time. For clarification, I do have ipad mini 4. and SD phone being SD660 on the Redmi note7.

                                Considering MTK always have to brute force their way in the smartphone apps, the d9300+ are very powerful. All apps the on the play store are usually optimized for SD based chip because they have the brand recognition. This is clearly seen when I'm using D9000. when MTK wins against SD, you can feel the apps being slowed and brute force instead of optimized for. And considering D9300+ do have them at almost top except this time, SD does win benchmark with some phone unlike during the d9000 time. Even in this situation, the dimensity doesn't feel slow at all.

                                Lastly, to the stability benchmark doesn't actually provide a good understanding of daily used. A BENCHMARK is designed to push the SoC to the limit. This means, any design the weren't meant to do that does it. Mediatek design with the D9300 using 4 X core and 4 A720 wasn't design to run at full speed. While using app with the power monitor tools turned on(can be find in the dev option), this chipset barely using the any of the X4 core. Most of the time, they are idling. You're are scrolling IG, FB, while using A720 core that are around 1.8GHZ, that is way better than using A520+A720(A720 needs to be used to load more content and video play). Highest speed Xcore are usually for opening apps.
