Arms
After a dramatic journey of not being bought by Nvidia, Arm announced its latest flagship CPUs. Coming soon to your Android 2023 devices, we have the Cortex-X3 and Arm Cortex-A715 CPUs.
As usual, these designs will be part of a cluster of system CPU chips. Assuming the normal design, the design proposed by Arm would have a 2023 SoC with a large Cortex-X3 core, three mid-core Cortex-A715 CPUs and four small Cortex-A510 cores, which are back from the current generation.
Arm promises that the X3 CPU will improve performance by 25% over the X2, while the Cortex A715 claims “20% energy efficiency and a 5% increase in performance” compared to the Cortex A710. current generation. Arm claims that the A715 is as fast as the Cortex X1 CPU from 2020. The A715 also drops 32-bit support, making it the last part of our flagship theoretical 64-bit SoC . The smaller A510 CPU is coming back, but Arm says it’s an “upgraded version” with a 5% power reduction.
A 25 percent year-over-year improvement just for the larger CPU won’t set any benchmark on fire. For reference, our tests showed that Apple’s A15 is about 38 percent faster (in single- and multi-core tests) than the best Android phones, and only increase the large CPU in 25 percent would mean that 2023 Android phones will still be much slower than an iPhone 2021. Apple uses the Arm architecture but not the Arm designs, as Apple seems to be a better Arm chip designer.

An arm’s length from real products
The Arm ad is only for designs that other companies can use for a real consumer chip, and most of the time that means Qualcomm or Samsung SoC. The distance between Arm and a final product means that you have to take the company’s projected performance claims with a grain of salt, as it has yet to be filtered through the execution of Arm’s design by d ‘another person. Last year, none of the Arm X2 projections came true. The company promised a “30 percent faster” CPU, when in fact, the X2-based chips on the market were slower or equal to the previous year’s X1 chips.
Announcements
There are already rumors that Qualcomm will not use the SoC design scheme suggested by Arm for its 2023 chip, the Snapdragon 8 Gen 2. SoC. The rumor states that Qualcomm’s design would be a Cortex X3, two Cortex A720, two CPUs. A710 of the current generation and three A510 CPUs. The justification for this would be that Qualcomm still doesn’t want to completely leave 32-bit support for the Chinese market, and dragging two A710 CPUs from 2022 until next year would keep the 32-bit train running.
Arm also announced a new GPU design, which is not normally used by most vendors. Qualcomm has its own GPU division, Adreno, and Samsung now makes GPUs with AMD. Your best bet for seeing a flagship GPU Arm in a product is with a Mediatek flagship SoC. For what it’s worth, the new ARM GPU has a brand new one called “Immortalis GPU”. The Immortalis-G715 is the first GPU-designed Arm with hardware ray tracing (Samsung and AMD announced a similar feature last year). Arm claims that the GPU is 15 percent faster than last year.
Amplia / Arm is telling its partners to go crazy with big chip designs and M2 fighting, but we’re not sure anyone will hear it.
Arm
Arm also expects vendors to augment Arm chips with SoC designs for laptops and desktops. The company introduced a new configuration that would involve eight X3 CPUs, four A715 CPUs and zero small cores. Arm tried to come up with the same idea last year when he suggested a chip with eight X2 CPUs, but we don’t think anyone accepted the company with that offer. Qualcomm plans to attack the laptop market by the end of 2023 with chips designed for its acquisition of Nuvia.
