ARM unveils Cortex-X3 (+25% peak performance) and Cortex-A715 (+20% efficiency)

29 June 2022
These are second generation ARMv9 design and both are 64-bit only. The little A510 core has no successor yet, but small improvements made it more efficient as well.

                  Hi Please attach prices on any featured divices, materials and etc.

                    Kangal, 30 Jun 2022What is the best chipset, depends on the best compromises, ... moreThe designs I'm mostly excited about are 0+5+0, 0+3+5, and 1+2+5. Here's why:

                    0+5+0: Has lowest latency!
                    5x Cortex-A73 cores which can be miniaturised on the modern TSMC-6nm will run very well. With the cache at a somewhat low (128KB each) amount, they will function similar to Cortex-A55 at low-end but can ramp up performance instantly. We're talking clockspeeds between 2.1GHz all-core, or potentially a 2.6GHz boost. Symmetry is the motto here. Multithreaded software will run fastest in this design, which dictates if this gets the best performance here or the lowest, but it's efficiency should be the higher than other options regardless.

                    0+3+5: Optimal balance!
                    Here we will use the DynamIQ / BIG.little setup, which is a net gain. However, since the software platform on AndroidOS is not fully optimised we have landed on this strange setup. We avoid the inefficient Cortex-X1 processor, and invest all that thermal potential into 3x Cortex-A78 cores (512KiB each) which can work together and CONSISTENTLY hit (2.7GHz) high frequencies. The small cores (64KiB) will also be given breathing room, at 2.0GHz all-core, so they can help if possible. There will be slight latency, but better than the industry standard. All-hands on deck is the motto. Efficiency should be great overall, no surprises.

                    1+2+5: Best Compromise!
                    While the Cortex X1 in general is inefficient and not very useful, there are certain uses for it. Very intensive calculations, particularly with Emulation (Xbox +), or Intensive Games, or Professional Applications may benefit greatly with the pure grunt (1MiB) it delivers. AndroidOS and the platform is somewhat optimised, however, peculiarities will cause delays in the above two options, and not-here. This design allows the X1 to closer to 3.1GHz potential, instead of throttling like other designs. To make the best use of this core, matching it with 2x Cortex-A73 that are small (128KiB) but work efficiently 2.2GHz will prevent from suffering too many stutters in the middle. The five Cortex-A55 small cores (32KiB), can handle idle tasks. They will barely hit the standard 1.8GHz frequency, and are needed to help boost performance in the midrange tasks. Latency begins to become an issue. Race-to-Idle is the motto here. Good efficiency overall, with sacrifices made to provide the option of bonus performance if/when necessary.

Take Android fans are their love of AnTuTu for instance, specifically how they can't help themselves in lording the 'higher' scores over their Apple counterparts. This despite AnTuTu themselves stating the numbers are not comparable between the two platforms.

                                And as to your reply to about Apple chips falling behind, yeah your dreaming if you think Apple haven't retained all relevant license's relating to ARM IP, and thus would be fully capable of implementing any of ARM's advances as and when they felt necessary.

Believe it or not, AndroidOS but more importantly it's Apps have evolved a fair amount in its day. Some new processor designs were thirsty, so using them sparingly was the better option, whilst others were more balanced in efficiency. The Cortex-A53 had "decent" performance back in 2013, and it is still comparable to the likes of the Cortex-A55, Cortex-A510, and Cortex-A515. However these are all deemed as "atrocious" performance now for 2023.
