After a remarkable trip in which Nvidia decided not to purchase Arm, Arm unveiled its newest flagship CPUs. The Cortex-X3 and Arm Cortex-A715 CPUs are about to be available for your 2023 Android devices. One large Cortex-X3 core, three medium-core Cortex-A715 CPUs, and four small Cortex-A510 cores from the current generation would make up the 2023 SoC in Arm's suggested architecture, assuming the usual configuration.
The Cortex A715 claims a “20 percent energy efficiency boost and 5 percent performance uplift” in comparison to the current-generation Cortex A710, while Arm promises a 25 percent performance improvement over the X2 with the X3 CPU. The 2020 Cortex X1 CPU is said to be faster than the A715 according to Arm. Although Arm claims it is “an upgraded version” with a 5 percent power decrease, the smaller A510 CPU is making a comeback. As a point of comparison, our testing revealed that Apple's A15 is around 38% quicker (in single and multi-core tests) than the top Android smartphones and that even with a 25% increase in the single large CPU, 2023 Android phones will still be much slower than a 2021 iPhone. Since Apple appears to be a superior Arm chip designer to Arm, Apple leverages Arm architecture but not Arm's designs.
Arm only releases designs that other businesses can utilize to create actual consumer chips, which is typically a Qualcomm or Samsung SoC. Because there is still work to be done on putting Arm's idea into a finished product, you should take the company's statements about predicted performance with a grain of salt. None of Arm's X2 predictions for last year actually materialized. The X2-based chips now on the market were slower or on par with X1 chips from the year prior, despite the company's claims of a “30 percent faster” CPU.
For its Snapdragon 8 Gen 2 SoC, Qualcomm is reportedly not going to follow Arm's preferred SoC architecture structure. One Cortex X3, two Cortex A720s, two A710 CPUs from the current generation, and three A510 CPUs, according to the rumor, would make up Qualcomm's architecture.
Additionally, Arm unveiled a new GPU architecture that is not generally used by most suppliers. A rare flagship Mediatek SoC is your best hope if you want to see a flagship Arm GPU in a product. What's more, the new ARM GPU now goes under the moniker “Immortalis GPU.” The GPU, according to Arm, is 15% quicker than it was last year.
We doubt anyone is listening when Arm orders its partners to create enormous, M2-fighting chips. We doubt anyone is listening when Arm orders its partners to create enormous, M2-fighting chips.
Additionally, Arm anticipates that vendors will scale up Arm processors with SoCs intended for laptops and desktops. A novel configuration with eight X3 CPUs, four A715 CPUs, and no tiny cores was proposed by the company. Arm made a similar proposal for a chip with eight X2 CPUs last year, but we don't believe anyone took the company up on that offer. Qualcomm intends to finally enter the laptop market in late 2023 using chips made after acquiring Nuvia.
