Refreshing a dramatic journey of not buy by Nvidia, Arm has announced its latest flagship CPUs. Coming to your Android 2023 devices, we have CPU Cortex-X3 and Arm Cortex-A715.

As usual, these designs will be part of a system-on-chip CPU cluster. Assuming a normal layout, Arm’s proposed design would feature a 2023 SoC with one large Cortex-X3 core, three medium-core Cortex-A715 CPUs, and four small Cortex-A510 cores, which are returning from the current generation. .

Arm is promising a 25% performance improvement over the X2 CPU, while the Cortex A715 claims a “20% increase in power efficiency and a 5% increase in performance” over the current-generation Cortex A710. Arm claims 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 theoretical flagship SoC that only supports 64-bit. The smaller A510 CPU is making a comeback, but Arm says it’s an “updated version” with a 5% power drop.

A 25% year-over-year improvement for only the largest CPU won’t set up any benchmark charts. For reference, our test shows that Apple’s A15 is about 38% faster (in single and multi-core tests) than the best Android phones, and a single big 25% CPU boost will mean 2023 Android phones will still be slower much more than the 2021 iPhone. Apple uses the Arm architecture but not Arm’s design, as Apple seems to be the better Arm chip designer.

Span length distance from actual product

Arm’s announcement is only of Designs that other companies can use for a real consumer chip, and most of the time that means Qualcomm or Samsung SoC. The gap between the Arm and the final product means you have to disregard the company’s claims of expected performance, as it still has to be filtered through someone else’s implementation of the Arm’s design. Last year, none of Arm’s X2 predictions actually came to fruition. The company promised a “30 percent faster“CPU, when in fact, the X2-based chips on the market was slower or by the previous year’s X1 chips.

Have was a rumour that Qualcomm will not use Arm’s proposed SoC design layout for its 2023 chip, the Snapdragon 8 Gen 2 SoC. Rumors claim Qualcomm’s layout will be one Cortex X3, two Cortex A720, two A710 CPUs from the current generation, and three A510 CPUs. The justification as this means that Qualcomm doesn’t want to completely remove 32-bit support for the Chinese market, and pulling two A710 CPUs from 2022 to next year will continue to work on the 32-bit ship.

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 make GPUs with AMD. Your best bet to see top of the line Arm GPU in a product is to go with the rare top of the line Mediatek SoC. For what it’s worth, the new ARM GPU has a brand new name called “Immortal GPU“The Immortalis-G715 is the first Arm-designed GPU to feature hardware ray tracing (Samsung and AMD announced a similar feature last year). Arm claims the GPU is 15% faster than last year.

Arm is telling its partners to go crazy with the big chip designs, against the M2, but we're not sure anyone is listening.

Arm also expects vendors to scale Arm chips with SoC designs for laptops and desktops. The company introduced a new configuration that includes eight X3 CPUs, four A715 CPUs, and no small cores. Last year, Arm tried a similar idea when it proposed a chip with eight X2 CPUs, but we don’t think anyone has accepted the company’s offer. Qualcomm plans to finally hit the laptop market in end of 2023 with chips designed by its Nuvia acquisition.
